In fact you can have the same CPU usage with International or Chinese version and zoom on by disabling logd and killing one process. You need to connect using adb. The video 1080p 60Hz is still stuttering though. With this mod, you need to disable zoom then reboot if you want to change your zoom settings :

#Activate ADB in dev mode and use an app to connect adb over wifi

adb connect <@IP>

adb shell

su

#We need to remount the FS to modify a file (to apply parameters on boot)

mount -o remount,rw /system

#Backup the original file

cp /system/bin/init_preinstallapk.sh /system/bin/init_preinstallapk.sh.bak

#Save some CPU (a lot!)

#Need to disable zoom and reboot to change zoom settings

echo "stop logd" >> /system/bin/init_preinstallapk.sh

echo "ps | grep trapezoidTest | cut -d\ -f7 | xargs kill" >> /system/bin/init_preinstallapk.sh

#Shutdown

reboot

Hi everyone,

First of all, thank you for all your great work by pushing our beloved Wanbo T2 Max to its limits; I already succeeded in booting directly on HDMI with adb commands, but I really need to boost/overclock the HDMI stream quality/fps (still some lags);

I'm using CMD and ADB command lines, and everything's okay 'till I got here:

4. Now using text editing app and manual edit the extracted .xml file with your package name within.

5. After edit completed, save and proceed with below command in your remote adb

I really don't have a clue how to find and to access /sdcard/SuperSU to modify the xml file, and WHAT to modify in it :/ Do I need to install a xml editor on the Wanbo, then launch it and open cpu_dvfs_scaling_antutu_packages.xml ? Then what I am suppose to modify?

Sorry for these noob questions, I'm new in all that; by the way, does "speeding up" the HDMI app helping avoiding video stuttering?

Thanks!

P.S: and YES, I'm using the zoom function; by turning off Wifi and Bluetooth, 1080p/60Hz is almost flawless 90/95% of the time, even if the keystone/zoom function activated.
[General Accessories] mikevirgil:
By the way, I got another bluetooth question: do you guys have issues with the T2 Max about bluetooth Lags/delays (soundbar, earpods, etc)? Is there any app/function/settings to solve this issue?
[General Accessories] AmateurPAL:
I got my T2 Max and using it for last 11 days. I found lag/shutter/framedrop issues in all the native video playback. In almost all apps I tried. I'm not using zoom or keystone corrections.

But I have no issues with the HDMI inputs 1080p/60Hz. Wifi and Bluetooth is almost always on. I'm connecting to my laptop through HDMI and done some rendering tests on MPC BE, but no tearing or other rendering issues found.

May I know, how do you test HDMI performance? Are you just experiencing the shutter issues, or testing through any app?

By the way, mine is an international version with firmware version W073_DC.1080T2.Zeasn.21010915. For me also there is no OTA updates available. It says latest version while checking.
[General Accessories] AmateurPAL:
I came across this PCB while tracking the company name found on the firmware OTA url. I'm not sure though. May be something similar: http://en.top-tech.com.cn/index.php?c=content&a=show&id=127

There are few other boards listed on this page. Please check.
[General Accessories] mikevirgil:
Thanks for your quick answer; I'm watching my ISP STB Box directly on the Wanbo HDMI port (no KVM/switch/splitter); I got to install the latest International OTA firmware (21030519). All movies watched with my STB are perfectly fine when displayed on my LED TV; as I stated before, almost everything's running fine on the Wanbo, except 5-10% of h265 encoded movies with some drop frames.
[General Accessories] peppebi:
I found that there is still stuttering when playing videos from an external source. It's a better performance compared to the internal apps but still not perfect. I think the problem is related to frame rate of the content because some 1080p file plays fine while some other have stuttering. It reminds me my nvidia shield tv pro 2019 that has a similar issue with netflix and you have to manually activate a beta function to have the correct frame rate. But in this case the issue is between the player and the app while with Wanboo is between the player and the projector itself. I'm saying this because I'm using it with an Amazon fire tv cube which can automatically adjust the frame rate to cope with the one of the contents but I think that the projector has some problem with these adjustments.
[General Accessories] Godin83:
Hi all! Very useful forum as I cannot find almost any information about this projector. I got mine a few weeks ago and pretty happy using it with a Xiaomi TV stick... there’s only 1 simple thing bothering me: is there any way to save the Zoom settings? It’s quite annoying to have to resize the projection every time I am turning on the device. I have it in a fix position so I don’t want to have to resize each time I am turning it on... thanks for the help in advance!!!
[General Accessories] jakseth:
thanks i will try
[General Accessories] mikevirgil:
Try to look for firmware update in this topic (look for 21010915 firmware in your model is the International version); once this firmware is flashed, you have to turn on developer mode and enable OTA updates, then you can have the latest firmware which fix the resizing issue :)
[General Accessories] AmateurPAL:
A general question:

why the projector is designed to project slightly upward? It's really annoying to place it forward tilted with something beneath!
[General Accessories] AmateurPAL:
Yes, me too have that doubt. It may the frame rate causing the issue.
[General Accessories] Mixalisios7:
Hello,

I made the last global firmware update and after that the projector doesn’t start.

The update was made by using usb 2.0 according to your instructions.

Is there any other way to reboot the machine for example through PC?

Hi everybody !

I'm trying to control my wanbo with the remote of my fireTV-stick - as you can do with a TV (Power & Volume). Unfortunately it doesn't work. In the setup-menu, are only TV's listed an no PJ. I tried a few settings (xiaomi and others - no success.

Has anyone a working 4-digit IR code for me.

THANKS !!

hi,

does anyone have this firmware available iQiYi version 20201229 (WB-T2Max1080CN-V1.00-20201229)?

thanks a lot
[General Accessories] nostupidthing:
Can't figure out how, can elaborate? thx!
[General Accessories] AmateurPAL:
I guess you can do the other way around. Use T2 remote to control Fire stick. You have to enable HDMI CEC to do that.

[General Accessories] zbutsam:
Hello everyone

I have also bought the international version of this projector and I'm moderately satisfied by it, apart from the fact that it lags frames in 1080p videos. So, I was thinking of installing the chinese launcher app to disable zoom function since I don't use it anyway.

My question is, will I be able to switch back to international launcher if I don't like the chinese one? And if so, how can I do it? As far as I understand, if you install a new launcher, it immediately takes over and you can't switch it unless you install another one. But we haven't got the apk of the international launcher.
[General Accessories] corass:
As far as I remember, press 2x home button on remote to change launcher
[General Accessories] nohaoo:
Sure, you can switch launchers whenever you want. In the device setting, there is 'home'.
[General Accessories] peppens1:
hi,

i've the global version.

anyone has audio problems if the audio is 5.1 type?

i explain.

I tried with chromecast and netflix and there is NO audio. But if i change the audio on netflix from a 5.1 audio to Stereo audio, it works.

I tried the FireTV stick and the same problem. With any video content with 5.1 audio, the result is MUTE.

I tried a DGTV hdmi decoder to watch the television, same result because audio is 5.1.

It's a very bad limitation. I think that is a codec/decoding problem.

I thought that i can buy a HDMI audio Switcher and send only the video to projector and listen the audio with the switcher by sending it to a soundbar or something else using SPDIF or 3,5 jack.

But with this solution i'll lose the capacity to control the volume with the projector remote control.

Do you know how to solve or if there is something to connect to the hdmi cable to filter the audio and transform it from 5.1 to 2.1 channel?
[General Accessories] peppebi:
The projector can't decode all the audio codecs available so you have to adjust the settings of the chromecast (or projector) in order to send only stereo audio. In my case I use a Fire Cube 4k and I send the audio to an external bluetooth speaker via Fire Cube.

I bought wanbo 3 weeks ago and i am very disapointed. Video from youtube and netflix has very few frames and sometimes viewing movies make me sick. I hope xiaomi will fix it with a new firmware. I have the global versiin. Also it shows that google play is installed but i cannot find it. It hslas its own market place. I should wait and give some more money to buy a normal one.
[General Accessories] Christos21:
Just bought wanbo. Very disapointed with the frames. When i see movies in netflix sometimes i feel sick. I hope xiaomi will fix it with new firmare. No playstore althought is installed. It has its own app store. Generally i am disapointed i should have bought a more expensive projector
[General Accessories] Xfades:
Xiaomi didn't make it, it's from their eco-chain, but Wanbo is making it. So Wanbo might release a new firmware but i wouldn't count on it.
[General Accessories] vedran2006:
i am no expert, but what i realized by pure testing is in VLC player if i resize the movie that stutters to 4:3 it improves drastically. so it may be that the issue is related to aspect ratio of the file, as T2 forces 16:9. can anyone that has some background knowledge confirm?

i have global version, latest firmware and i turn zoom off. play from VLC on projector connecting USB extrenal drive to T2.
[General Accessories] peppebi:
I will try.
[General Accessories] pitju:
The problem is that the projector stopped working once in the opening menu, it went dark and I restarted in vain. The system seems to be loading, connecting to the bluetooth device, but no menu, just a dark image. Is there a solution for this? The machine is still new. (Global version)
[General Accessories] bacecek:

I just check with the china retailer customer service. according to them, iQiYi version and the other china version that is able to flash to global firmware uses different mainboard. as such, there is no way for iQiYi version to flash to global firmware/the other china firmware or vice versa... too bad...

[General Accessories] Neogamaes:
Hi,

Thanks for this great topic.

I have 1 newbie question. Can I directly connect to adb wirelessly the first time I want to connect to the projector or do I need a USB step first ?

Thanks for your help,
[General Accessories] Neogamaes:
Do you mind typing out the commands here for changing the resolution over ADB and also to activate the zoom settings?

Thank you
[General Accessories] Coldieee:
I can't remember 100%, but I think you can just install one of the "WiFi adb" applications from the PlayStore. So no need for usb.

To change resolution it is the standard adb command, e.g. adb shell wm size 1280x720

You can also control the zoom feature using the pre-installed application. However if you want to fully-disable zoom, then the Chinese launcher is recommended.
[General Accessories] Neogamaes:
Thank you for your quick answer!

Fabiogenk was mentioning a 720p but with a firetv stick remaining at 1080p.. I wonder what it means exactly...

I have the global version but I need the zoom since the projector is a bit on the side..

I just hope to have something fluid with my firetv stick.. even if I have to go down to 720p.
[General Accessories] kagaya81:
New version is also shown in their china official website.

The price is advertised as RMB1599 (USD248.40). The current version is selling at RMB999 (USD155.19) in most of the china websites. almost USD100 increment.
[General Accessories] Coldieee:
I think fire stick will always match the resolution of the projector. However some apps have the option to play downscaled 1080p/4k content.

Turning the projector's WiFi and Bluetooth off may help a little with frame drops.
[General Accessories] Neogamaes:
Alright. Thank you very much for your answers. Everything's clear. I will indeed stop WiFi and Bluetooth: Can I do that simply in system setting or do I need again to go through ADB ? (If yes a lil help on the code would be perfect 😅)
[General Accessories] proview77:
This worked for me.

I changed this projector 720p, but fire stick remained 1080p resolution.

When I use smartube, The difference between stock software and firestick is huge.

Firestick shows way better quality.

Netflix, youtube with firestick plays 1080p 60 smoothly using zoom option.

I think external device like firestick can be a good solution for the lagging performance of this projector.

Ola eu tenho wanbo t2 Max global como que faço para desligar o zom dela para não perder mais a queda de taxa
[General Accessories] gordnnnn:
hey, i've got this tiny little projector now. (global version 21010915) yes there is a little bit of 1080p/60fps video stuttering.

I have done those things :

in developer options i turned off all animations.

also in developer options i set 1 background process.

(don't give work this litte thing)

i disable all apps which i can cause i don't need this ****ty ui also gapps.( can't understand why someone will stream content via netflix and prime video during the native apps. no videvine L1)

Turned of Bluetooth and WiFi and Switch HDMI EDID Version to EDID 1.4

and now.....voila

i'm using a miTV stick, and after all that done the performance is MUCH MUCH better. yes, there are still some micro stuttering, but this isn't to bad at all.

Now i love this tiny little projector. The picture is awesome If you remain the price of 130€.

But now my question....i downloaded your file. you say ist version 21030519, but after flashing it, i am still on 21010915.

i also put ota test mode on, but it says that i am already on latest version.

Can someone give me a link to 21030519 please? cause i don't can find anything...

Edit: turned on my wanbo this morning and Start watching. I see stuttering again.

Then i have a Look in Developer Options and i see the Background processes are on Standard again. I Set it Back to 1 and stuttering disapears 😁

Did anyone now why the setting didn't was save?
[General Accessories] Josefkappa:
Received yesterday my T2 Max, I lower its resolution to 1280x720 and did some tests with a Chromecast 2. It seems to work very well also with zoom/trapezoid correction on. I can confirm that Netflix, Prime Video and Youtube play 1080p smoothly.

UPDATE: I did other tests, always with Chromecast 2, zoom on and lowered resolution, after all it seems 1080p playback isn't perfectly smooth. I'll try to install Chinese launcher to deactivate zoom and see if there are differences in playback smoothness.

UPDATE 2: Yes, with zoom off playback is perfect (to my eyes, at least), no stutter at all.
[General Accessories] peppebi:
Guys no matter what you change in settings: this projector is crap and can't process video signals correctly. I don't think is a problem of resolution because you will have stuttering watching 720p videos on youtube or even if you watch sd contents. With an external device there is no frame drop (tried with youtube) but still you will have some stuttering so the only answer I have is: crap!
[General Accessories] mohjax:
Guys,

A little help pls... I updated my wanbo t2 max using the usb thumbdrive + power button (10 sec) and I seemed to brick the thing... only thing showing during the restart are vertical lines on a blue background...

Any idea what to do with this? Thanks
[General Accessories] Josefkappa:
As reported in this discussion, to deactivate the zoom in global version you have to install the Chinese launcher. You can find it here: https://xdaforums.com/attachments/newlauncher-1-0-zip.5196695/

I translate your question with Google, hope this is the right answer ;)
[General Accessories] gordnnnn:
Dude, you're right. This projector isn't a game changer. But, check the difference with 1 Background processes Limit.

I also use external Hardware. The onboard Software is truly crap.

But think about people who won't spend 500€ or more...and for the money of 130€ you got a massive real 1080p Image.

Yes color, contrast etc is not the best, but this projector isn't crap at all.

It's a inexpensive option to get some Cinema Feeling at Home.

#nohate
[General Accessories] peppebi:
I strongly disagree. I have done more or less everything you suggests one month ago and yes, there is some improvement but it's far from being perfect.

What's the point of having 1080p or 720p or 4k if the projector struggle to reproduce contents with the correct frame rate?

What's the point to have android if when you use it your eyes bleed? I would have rather have a projector without android and use that money to have a better motion handling when you connect an external device.

I have just bought a used Optoma hd33 (I only paid 5£!!! They sold it as faulty and instead was perfect and I only had to clean some oxyde on the board inside) and at 1080p is far, far, far better than this crappy thing. Same as other cheap chinese projector that you can find on amazon but they are not portable.
[General Accessories] gordnnnn:
Not everyone got a full hd projector for 5 bucks.

I only wanted to give my settings to this Thread and hope it helps someone.

It normal that when you spend Money, you will get a better projector.

But this one isnt totally crap. With this settings my eyes didnt bleeding any more 😉

[General Accessories] proview77:
I don't remember it exactly because it was long time ago.

I used 'remote adb shell' in playstore.

After installed 'remote adb shell' , I checked wifi address in setting of t2 max.

By using that address, I connected between phone and t2max via 'remote adb shell'.

After that, I wrote "wm size 1280x720".

That's all.
