I got mine last week with Android 9 and the installed Netflix and YouTube app both play 1080p. You always must choose open - never choose update or they'll probably stop working. You can do a firmware reset if you tried updating. Also I updated to the latest firmware (from page 2 by Titanium) and this really improved the smoothness of playback.
[General Accessories] n3w0rk:
Thanks alot. The system feels more stable on this version. No lags by navigating through options.

Which alternative Launcher are you guys using? Stuck with Wolf Launcher. Every app incl. Sideloaded apps are shown and easily accessible. But is there something preferable, better in regard of features?
[General Accessories] MB183:
Actually, I've noticed an odd side effect of the latest firmware - the options button (to the right of Home) no longer brings up the quick menu. A bit annoying as you can't change the picture settings with the current image on screen.

Has anyone tried Projectivy Tools on the T2 Max ( https://play.google.com/store/apps/details?id=com.spocky.projengmenu&hl=en&gl=US ) ?

I've used this on another Xiaomi projector and it was handy as a launcher. I'll probably try it later this week.
[General Accessories] MB183:
I loaded winscribe and it worked fine. Loaded it from the play store directly. I'm in NZ.
[General Accessories] sandtang:
I've emailed wanbo and received no reply after 1 week.
[General Accessories] MB183:
What are you asking? Trapeziod settings are designed to square up the image if the projector isn't place directly in front of the wall and at the right height.
[General Accessories] sandtang:
Oh I asked about netflix incompatibility after updating the app.
[General Accessories] a1790t:
Hello everyone. I have a wanbo T2max projector, please tell me how you can send audio via hdmi to a converter. and from there to the 5.1 system

(the converter was purchased on aliexpress)
[General Accessories] MB183:
Right... As far as I know the Netflix in the firmware must bypass some checks (like mac address) so the only thing to do is do a factory reset and DON'T update Netflix. Mine's working fine at 1080p.

Otherwise I did see a youtube (All Things China) where he has a firmware for the T2Max with a mac address tool and a netflix.apk file that might work. He has a later video for using a third party APK for YouTube, Netflix and Spotify.
[General Accessories] sandtang:
Thanks. Might check that out cos high chance we'll accidentally click on default highlighted 'update netflix' button then I'll have to go through hassle of re-setup again (and again).
[General Accessories] aumeilo:
I bought t2 max 9.0 few days ago,

Major problem other than lagging when using zoom, is the brightness problem.

For youtube or in machine app, i can adjust brightness value in settings, however there is no changes or reaction.

For using HDMI, i can adjust brightness and i can see the difference when im changing the value, indeed the changes is just a bit.
[General Accessories] oldman20:
can u play videos wothout said: "only availble on smartphone"?
[General Accessories] MB183:
Yes.

When I first ran it it asked [Update] or [Open] - I used open and was able to login and use it as normal. It supports the remote buttons and you can also use the mouse function on the remote to select movies/shows.

This worked both on the original firmware that came on the unit (I think Nov2021) and the one I update to from page 2 (Apr2022 I think).
[General Accessories] oldman20:
can you share it? thank you
[General Accessories] MB183:
It's the one from post #38 on page 2

The T2 Max only has 3.5mm stereo audio out or Bluetooth audio out capability. To use the above box you'd have to have an external HDMI source (like FireTV, Chromecast, Xbox, etc) connected to the input of this box and the output HDMI connected to the projector and a Toslink cable to your 5.1 amp.
[General Accessories] tpierot:
One doubt I have the t2max android 9, when I focus it on the wall at 1080p it seems to run at 480 and the fluidity seems bad, I don't know if there is an update to improve those aspects or what I can do to improve those aspects

(I already tried the updates on the previous pages and they didn't work, just notice that it improves the time of the bluetooth sound)
[General Accessories] blackhawks1211:
im sorry but im not sure what apps do you run, but im assuming it is a built in netflix, if it so then i got the bad news. Built in Netflix apps only detect Wanbo as phone, hence it only can ran up to 480p. but if you want to try using HDMI, it can support up to 4k, but still display it as 1080p. Hope it helps
[General Accessories] blackhawks1211:
Does anyone know about "PC Mode" settings in the Advanced Video? not sure what it is doing
[General Accessories] MB183:
I'm getting 1080 using the inbuilt Netflix. But testing via HDMI (or a movie on USB) is a good way to check the projector.

The T2Max is only 2.4gh wifi so maybe check you wifi strength. Also do you have a T2M+ ? there is a T2 Max Life that's only 480p native.
[General Accessories] Joe Ferrara:
Hi all! I have a problem with my T2 max with android 9. I have the latest firmware but my PJ suddenly shuts down and no images. It tries to restart but it fails. I installed the firmware 2-3 times but after a few hours of projection it shuts down. It seems like it loses the firmware. I don't know what to do. Any suggestions to what to do to use the T2. I already had the same issue with the previous firmware. I bought it on Banggood last December. Now is just a box on the table...
[General Accessories] sandtang:
Does not sound like firmware issue to me. Sounds more like a hardware issue. Make sure you allow air to circulate through the projector so it is not overheating. It will shut down if overheats. Otherwise, get it replaced if under warranty.
[General Accessories] Joe Ferrara:
Dear sandtang, I have the PJ to avoid it overheating. I can't replace it since I tried to ship back to China but it returned to me... How can I fix it if possible?
[General Accessories] sandtang:
Sorry I'm not familiar with fixing projector hardware. Perhaps others can help.
[General Accessories] Joe Ferrara:
Anyway, many thanks Sandtang. I hope I can fix it.
[General Accessories] Joe Ferrara:
If anyone has a suggestion to what to do is welcome!
[General Accessories] Vaca3000:
I just bought the T2 Max (T2M+) it has the same firmware as andresouza and android 9, but the input lag for games and the general choppiness are making this thing just unusable. There are any solutions for this model with the march 2022 firmware besides waiting for a new firmware?

Edit: I’m using this one

https://www.mediafire.com/file/m2mj8m7v3v7sv3a/D9-220312-EN.zip/file
[General Accessories] andresousa.com:
Hi! I was able to solve the lag issue on Xbox Series S by taking out the image setting. I took it from Soft and others to USER and I myself put a color that I liked, it stopped generating delay.

What should happen is that it gets heavy to process the image with the chosen color and there are small delays.

Try it and tell me if it's improved.
[General Accessories] Vaca3000:
Oh I see. Are you talking about color temperature? I’m using everything on user config but playing Mario kart 8 with the switch is just awful. The input lag is huge.
[General Accessories] renansc84:
Try this, set game console to 1080p 50Hz, in T2 developer mode put on force render 2d and 1 app background active
[General Accessories] blackhawks1211:
Does anyone know that we can do adb command on TvOS version of wanbo t2 max?
[General Accessories] Vaca3000:
Hi Renan, thanks for answering but sadly is not possible to change the refresh rate on nintendo switch manually
[General Accessories] djfred:
Its firmware ( costume phone android ) is not suitable compared to Android tv, I Don't know why they don't install Android tv on it like Xiaomi-owned video Projector. What's the email of this company or customer care line for recommending this, even we can send an email to Xiaomi that this side company not doing well on firmware.
[General Accessories] a1790t:
Thank you, everything worked as you said. Or maybe you know how to send sound to the JBL 3 speaker
[General Accessories] Joe Ferrara:
No help for fixing my T2 Max?
[General Accessories] sandtang:
Just want to share in case anyone else out there is using VLC android to play videos via DLNA, do DISABLE the VLC's hardware acceleration setting in T2Max, otherwise the video quality will be poorer.
[General Accessories] MB183:
did you say it was a problem with the original firmware of shutting off after a few hours? Sounds like it overheating. If you can't easily get a warranty replacement maybe open it up and see if the fans are running.
[General Accessories] blackhawks1211:
i dont have chinese device personally, but if its not a hardware issue, maybe try to unplug it first, then after plug it in back only then you hold the power button because based on the email reply i got

Hello. you can try this firmware
1. download and decompress，copy the system files（5 files） to the u disk（Format：FAT32）, decompress and compress them in the root directory of the u disk, plug the projector into the u disk, and then connect the power supply（Important steps）.

2. Waiting for about 10 seconds，will have a progress bar indicates the upgrade. If there is no progress bar, you can try steps 1 and 2 again.

3. After 100% completion, please wait for about 5 minutes. After the data is loaded successfully, you can enter the interface.

unplug and plug the power brick is the important step, maybe you can try that one first
[General Accessories] nookey1280:

Does anyone know how to access the developers option menu? I want to activate GPU rendering to see if I get a better framerate when reproducing video from an USB.
[General Accessories] n3w0rk:
Not necessary. Install this APK and it will show a Shortcut to Developer Menu https://xdaforums.com/t/app-firetv-noroot-launcher-manager-change-launcher-without-root.4176349/
[General Accessories] blackhawks1211:
Niiceee, i will try this one, and hopefully it works

Thank you

Edit:

It does work but it doesnt show any resolution option in developer option, i wanna change resolution to 720p in TVOs in hope of i can use keystone without framerate drop, but thanks anyway for the answer
[General Accessories] n3w0rk:
Only possible with ADB (or root?)

Quick Tutorial:

Download and Extract this ZIP file: https://dl.google.com/android/repository/platform-tools-latest-windows.zip

Open the Folder "platform-tools"

Hold Shift + Right-Click on any empty area

And choose "open command window here"

On your Projector. Go to Developer Menu and activate USB- Debugging + Wireless Debugging.

Note: Once Wireless Debugging is active, your WiFi will stop working on next reboot (Be sure to de-activate it again once you're done.)

Go to your TVOS Settings -> Network Settings -> Select your current connected WiFi and remember the IP-Address displaying.

Back on your Computer. Write down adb connect <ipadress>

Once he succesfully connects then simply write down

adb shell wm size 1280x720

or

adb shell wm size 1920x720

then at last adb reboot. Hope this helps.
[General Accessories] Diego19891989:
How do you stream using the VLC app? I can't find a streaming option in the app
[General Accessories] sandtang:
In VLC app, select Browsing, select Local Network. Your media server will show up here (sometimes need to wait a few seconds for it to appear).

You can then favourite your media server so that it'll appear at the end of the Browsing list, faster to access in future.

Tip: go to vlc app Settings, DISABLE hardware acceleration to get better video playback. Default is Auto which renders videos in lower resolution and less smooth.
[General Accessories] oldman20:
is it permanent?
[General Accessories] Diego19891989:
Do you think that we will get OTA updates still after installing this software?
[General Accessories] Diego19891989:
Ok. I managed to get 60 fps in video reproduction with the T2Max and zoom activated! I installed the latest firmware, which was shared here in this thread, I activated CPU rendering in the developers option using an APK to access that menu, and I use VLC media player with “hardware acceleration” deactivated in settings. Now the projector plays movies just like my computer.
[General Accessories] Diego19891989:
Did you find the solution to this problem? I'm in the same situation as well
[General Accessories] jorferri:
Nope... I had to return it as the support service was awful
[General Accessories] blackhawks1211:
do you have android version or tvos version if i may ask? and when you say VLC media player is it from your pc via hdmi or using apps inside projector?

thank you
[General Accessories] Diego19891989:
I found a work around. The proyector needs to be turned off and on for the changes in video settings to take place. So, you can't adjust video settings in real time, but you can adjust video settings restarting the proyector.

I've read somewhere that if you plug in an HDMI cable, you can adjust video settings in real time while playing a movie from your computer (buy I didn't try myself). It could be a way to adjust the image in real time.
[General Accessories] Diego19891989:
Check my last response. I think I found a solution
[General Accessories] Diego19891989:
My proyector came with Android 9 and it still has Android 9. However, it is a version of Android 9 mod by the manufacturer. It is called TVOS by the manufacturerer in settings/info. Basically, I updated the proyector to the latest version (which is not available via OTA, but it was uploaded by a user here in this thread). In fact, there are two versions uploaded in this thread. I tried with one, it didn't update the proyector. So I tried with the other, it did update the proyector.

And when I say VLC, I'm talking about the app in the proyector installed from the play store. The film is on a USB thumb connected to the USB port.

But I'd like to refine something that I said. I said that the film plays at 60fps, but that's not exactly true. What I wanted to say is that it plays exactly like in my computer, without any stutter. However, films normally play at 24fps (that's how they are recorded). If you are used to game at 120hz, you will find some choppiness if you look for it. But that's not a problem of the proyector.

Some notes related to this device

I managed to fix "Unable to obtain MAC address" error on wifi connection in this way

Go within Settings -> About Projector -> Hold click button on Version for few seconds -> usb debugging on OFF (that enable ADB over wifi without third-party apps. adb over usb instead doesn't work remaining on charging status)

Then reboot and everything seems fine.

I'm also looking for ir (remote control) mapping in order to use my phone IR blaster.

Looking at the dmesg logs, seems to use this mapping. I'm trying to write a lirc config and load it with irplus app

Hello question, is there a different android os 9.0 or firmware? Because my Android os 9.0 has a different UI interface. Mine has a blue UI interface like an old version. I have a Xiaomi android tv stick (android os 9.0) and the UI interface is not like this. Thanks in advance!
[General Accessories] MB183:
Yeah, this is the Whale Launcher (you can install other launchers).. I have this too... seems to be what they are calling TVOS built on Android 9. I'd prefer the proper Android TV experience. Does anyone know how/where to get a firmware for this projector?
[General Accessories] AGluk:
Hi guys!

I have the same projector, and it looks like I've bricked them.

While firmware updating, it reboots on 53% and doesn't power on anymore.

After applying power, the red LED starts to light and that's all. I can't power on it, not by button nor remote.

I have C003_368V35LVD_D3 2L board inside.

Maybe there is some way of booting it in FASTBOOT restore mode? Like on the phones...

Hope for you help!

Found some UART on back side of the control board. Maybe it can be used for recovery procedure?

Has anyone encountered Netflix Error 0013? Sometimes my Netflix on this projector showed 0013 error and can't seem to find the solution, some sites suggested general fix for this error is to try the different version of Netflix, but I think I shouldn't mess with Netflix version since we cannot update it. Mine is still the version came out from factory.
[General Accessories] Jeffreylyr:
Hi all, so last week i accidentally ALMOST bricked my t2max android 9 by factory reset through ( Projectivy Launcher -> Mediatek Settings -> Factory settings ).

It sort of deleted stock video profile/decoder??(ive no idea where it went wrong) after the reset. After which my HDMI output is red tinted, built-in youtube app videos are red tinted, any form of video is red tinted. Homepage/ settings etc are fine, (FYi) changing red gain/saturation doesnt help.

So i dialed in to China support. Through whatsapp and email convo, they sent me a latest firmware for June 16, 2022.

Download link:

[Edit] Based on email snipplet attached, the above download link expired on 30/07/22 18:44 hrs. Here is the new link

https://xdaforums.com/t/wanbo-t2-max-android-9-0.4426961/post-87227573

(update method is the same mentioned in this thread -> Off -> Unplug power -> Plug in FAT32 usb with the files -> plug in power -> press power button and hold -> update screen immediately ELSE repeat steps)

Hope this reply helps, Together with the lastest firmware here ( 16-06-2022). Reply to this to keep track of new changes that ive not noticed/ listed). TYVM

New things ive noticed:

1. It fixed my red screen issue mention above

2. It solved the bluetooth latency issue mention in this thread. No choppy audio anymore !

3. WIFI run at its normal 2.4ghz stipulated speed instead of throttling when bluetooth is connected. Roughly 2~15mbps which is normal for my house.

3. Accessibility setting is gone ( not in common settings). Not sure where to find it anywhere else

4. Auto Audio route to AUX output on boot( which is supposed to be like this on any device)

- Prior to update, i still have sound output through its built in speakers despite me plugging in AUX to my amplifier on every bootup. So i have sound both from my T2max and amp, which was annoying as theres latency in my amp side. Only solution was to plug out and plug in AUX cable in order for sound to route to amp instead of BOTH built in and amp.

Same things Not fixed

1. Changing picture settings (real time) only works in HDMI. Home launcher doesnt work in real time. (Same as before)

2. Background apps still automatically closes aft inactive for 4~7mins (which is annoying as i need a vpn app to run).. Need some help if can

3. In built Apps(Youtube etc) /USB media playback Still choppy when it plays 2k ~ 4k videos. 1080p60fps with HDR = LAG. 720p60fps with HDR playable.

1080p60fps no issue.

Lastly, piece of advice, DONT MESS WITH Projectivy launcher -> MEDIATEK SETTINGS unless u know what ur doing.. a factory reset is a click away without confirmation.

AND !! DO NOT!! ever click aging mode (DO NOT!! I REPEAT!!) .. With the newest firmware installed, You will be stuck in aging mode. Unable to exit, unable to shut down/navigate etc. Even after you turn off socket, and reboot, it will still be stuck in aging mode.
[General Accessories] Jeffreylyr:
Press the menu icon on controller when in HDMI mode. The middle option allows you to change screen zoom/ 16:9/ 4:3 etc .. If this doesnt work , it might be on your source side ( Pc)

In regards to this, I have uploaded tons of pictures to show my current 'setup', including projector video/picture settings.

Setup:

> budget 100" ALR screen @SGD18. Helps in daytime viewing / Ceiling light "disturbances" . You will notice vibrancy differences as compared to a white cloth/plain wall/ normal screen in both Day and Night/Dark room. Though viewing angle is very limited in daytime, And projector must be placed NOT more than 5°~10° horizontally , vertically NOT more than 1 metre from eye level.

> Projector in pictures is roughly 2.3metres ( estimated) away from screen.

> Projection screen size should be roughly 90" (estimated)

Photos taken

021505 - Room with ceiling lights On

021447 - Room with table lights On

021522 - Complete dark room

140909 - Day time condition with ceiling lights Off

021317 - Overview (Pardon/ Ignore my messy room)

021323 - Over-Overview (Pardon/ Ignore my messy room)

Disclaimer~ these are my personal preferences for a "FHD/UHD MOVIE EXPERIENCE~" . May not cater to everyone's taste buds as screen will be on the colder side/ slightly more blueish

____________________________________________________

Here are the settings in text in case you dont wanna open every photo to refer.

** Do note to do these edit in HDMI input mode to see the changes reflected immediately

> Brightness: 50~60

> Contrast: 46 ~ 56

> Saturation: 50 ~ 70

> Hue: 0

> Sharpness: 6~11

> Gamma: Dark ( Or others depending on your comfort)

> Colour Temperature: 48, -2, 20 (Follow this tgt with colour tuner)

> HDR: ON ( if possible)

> DNR: Off

> Mpeg NR: Off

> MaxVivd: Off

> Adaptive Luma: Off

> Local Contrast: Off

> Blue Stretch: Off (tbh ive no idea what this does)

> Game Mode: On (may be placebo effect, but screen refresh feels faster)

> PC Mode: Off (unless you wanna tweak colour settings from your PC side aka through Nvidia/ AMD graphics software, else Projector video/colour settings will be "bypass-ed". Aka running based on what you'll see on your physical monitor.)

* Colour Tuner: [Follow this if you want to have nice colours :)]

> Hue: <Red: 56> <Green: 59> (For an "ideal" purple)

> Saturation: 51, 49, 51, 51, 50, 58, 47

> Brightness: 57, 44, 57, 50, 50, 50, 50

> Gain: 45, 38, 49

-- After you're done, you can turn off Colour Tuner and see the differences for yourself.

* 11 White Point balance corre: [TBH, i see no differences for this]
