Yup I have a sharp next to my tianma for the day

While technically the sharp is better in brightness and view angles it does indeed suffer from vertical lines visible in whites

For a pixel peep like me the Tianma mouth watering colors and crystal clean whites are much more essential for my needs

To be honest, the sharp view angles are not really better they are simply greenish instead of reddish

Tianma is staying

[MENTION=1144067]hamdir[/MENTION] what color setting do you use with your Tianma panel? Just got my 10 yesterday.

Vivid? Where do you put your slider?
[HTC 10 Guides, News, & Discussion] richii0207:
Interesting. How different would they both look from an angle in portrait instead of from the side?

We finally have color control on htc 10 thanks to [MENTION=3088420]tbalden[/MENTION]

I'll try to fix the red shift on my panel and do a comparison next to a sharp unit
[HTC 10 Guides, News, & Discussion] cdd543:
Wow. I sent two units back because of the tianma screens. On verizon now and wish I could get one with a sharp panel.
[HTC 10 Guides, News, & Discussion] fun_key:
[MENTION=1144067]hamdir[/MENTION] I am very interested by your results.

IMHO it is not a calibration problem as the tinge is especially visible under angle, but rather a property of the panel (or one of its component) but I would love to be proven wrong.
[HTC 10 Guides, News, & Discussion] hamdir:
sorry i didn't post pictures so far because ill need another device next to it for comparison, otherwise i will have to place my phone next to my phone in Photoshop

but for now here is a more specific explanation:

This a tint caused by the lamination glue solution and so far we have two solutions coming from HTC factory even on the same type of panels, some having red bias with red shift on angles and some have a green/yellow bias with green shift on angles, in case of the red shifting solution it does tint rather agressively once the screen is angled

so will the color calibration fix it? no not completely but it does improve it drastically, let me explain why, in the drawer of the Sense launcher / stock theme it has a grey color background, on a redshift affected Tianma panel this grey has a clear red bias when i reduce the R in EX kernel i get a perfect grey, the view angles are improved greatly as well, my unit is already cured so its pink shift is already a lot less than it was when it was unboxed now with red reduced it gets even better, however if we place them side by side another HTC 10 which has the more greenish lamination no matter what we do in front of the camera the pink bias will still appear exagerrated even if the R is reduced (unless you drastically reduce it and break your calibration) but to my own eyes i dont see it now where near as bad as the camera shows, in fact it looks completely fixed for me

so the short answer: yes you can improve it greatly via calibration but not solve it completely on extreme agnles
[HTC 10 Guides, News, & Discussion] earazi:
Well I did originally have a sharp panel, but I needed the digitizer replaced as the top of the screen went weird when dragging down the notification bar

I now have the a Tianma panel. Buzz has gone as well. I guess htc use Tianma for replacement even for sharp panels. It's still the same phone casing and imie.
[HTC 10 Guides, News, & Discussion] ElementRn:
I just received my HTC 10 replacement, which has a Tianma screen. My previous device had the sharp screen. I use my phone for endless hours everyday, so I remember the look of the screen exactly. On the sharp panel white always looked a bit dirty. The Tianma panel is way better. At least the loss of my first device has a sense now.
[HTC 10 Guides, News, & Discussion] arrowblade:
Can anyone check out their Tianma panel and see if they got the lines on it? Only sharp is supposed to have it but mine is Tianma and I was able to get a clear photo of the panel...
[HTC 10 Guides, News, & Discussion] omar302:
I have the Tianma display (Silver/white model) & I can see the lines, but I have a screen protector on (tempered glass), so I cannot be certain if the lines are from the display or protector.
[HTC 10 Guides, News, & Discussion] arrowblade:
Thanks for checking, up to now I hadn't had any clarification whether the lines were a sharp only thing or not. I also had a glass protector too and I removed it eventually because i also wondered whether it was the cause of the lines, but also because the 10 looks better without the protector. Still had lines though!
[HTC 10 Guides, News, & Discussion] richii0207:
Those lines are what registers the touch for the display. There should be horizontal and vertical lines forming a matrix.
[HTC 10 Guides, News, & Discussion] arrowblade:
Yep, i guessed it was the digitiser thing for the touch input as i had seen other kinds of patterns on my previous phones!

But i was just checking specifically in this case because people had been saying that only Sharp had lines and Tianma didnt so i was quite surprised when i found them.

Cheers!
[HTC 10 Guides, News, & Discussion] TheHappyBuddhist:
Got my device delivered today from HTC UK. Tianma panel. Pink shifting is there. But I have been using it for sometime now and I feel that its getting reduced. But still, pink shift is there compared to my LG G3 from which I'm writing this. Hopefully it might get better in few days of time.

Tianma on Glacier Silver EU version. don't notice much of pink tint even when looking from different angles.
[HTC 10 Guides, News, & Discussion] xdn:
I've had 2 Tianma units for a week (one of them will be returned or maybe both) and I see no improvement with the pink tint. I have the phones with maximum brightness, 1 hour timeout and I try to keep the screens on as often as possible.

Those of you who have seen improvements with the pink hue, how long did this take? Were they minor improvements or the panels are now looking fine under all angles?

(quite disappointing BTW that this was not mentioned in most reviews)
[HTC 10 Guides, News, & Discussion] Kisakuku:
No longer an issue at reasonable viewing angles if you're running a custom kernel with KCAL color control.

Hey Guys (and Girls....)

We need your help.

Could you install the FPS2d app from the Playstore and run it?

You will get 50FPS if you're on Stock. So you need to keep the finger pressed on the screen the whole time to achieve 60FPS. (or activate High Performance Mode in dev settings)

And i'd like to know which ROM (and mods) you're using and what FPS you achieve.

What it looks like only Sharp panels will achieve 60FPS while Tianma are stuck on 57/58 FPS.

If we could get a few more people to test this that would be great :good:

Thanks in advance. :cowboy:

What's with the FPS trending in the thread? Is there something in a display that's affecting fps that I'm unaware of?
[HTC 10 Guides, News, & Discussion] Haldi4803:
Maybe, it's called VSync. It keeps the Framerate at the refresh rate of the Display.

Normaly PnPmanager keeps the Refresh rate on 50Hz to safe battery, TouchBoost increases that to 60hz.

Or as it seems to 58hz only and not 60Hz.
[HTC 10 Guides, News, & Discussion] richii0207:
The screen refresh rate itself is 60 Hz, which is how fast the screen can refresh it's images, or the hardware side. FPS is the image processing on the software side. When FPS>Hz, screen tearing can occur. If you have a low Hz monitor, you usually want to enable V-Sync which will limit your FPS to your monitor's refresh rate in order to eliminate screen tearing, as you mentioned.
[HTC 10 Guides, News, & Discussion] allhill:
Mine, HTC 10 32GB Carbon Grey Taiwan Version

Dunno which better :)
[HTC 10 Guides, News, & Discussion] Haldi4803:
AFAIK Vsync with Triple buffering is Default activated since Project Butter.

Therefore FPS will never go over Screen Refresh rate.

So if its NOT Vsync thats Limiting our Apps to 58FPS... What then?

It is happening on Stock HTC Rom and on Beanstalk CM13 (which uses Qualcomms Driver) so what Software is installed on Both ROMs... Or is it maybe really a Hardware issue? As some people did Report Back 60fps.

At First we had 3 Tianma with 58fps and One Sharp with 60fps. So the First tought was Sharp has proper 60hz Refresh rate. But thanks to All the people participating here we now know that even some Sharp Panels Limit on 58fps.
[HTC 10 Guides, News, & Discussion] King p1n:
Got a carbon with Tianama it's not that bad honestly, temporarily until I'm leaving droid for iOS guys
[HTC 10 Guides, News, & Discussion] richii0207:
The FPS could vary based on throttling due to heat or slow scaling, as seen on multiple rigs with the same specs and sometimes even the same rig will change in FPS benchmarks.
[HTC 10 Guides, News, & Discussion] Haldi4803:
If you would have taken a look at the Link in the Post where I asked about FPS of other people you would have seen that I made an T-rex Benchmark in 1080p one time Normal 58fps and one time Off screen 92fps. So no. Its not GPU throttling issue, its directly related on how the frames are shown on the display.
[HTC 10 Guides, News, & Discussion] TeroZ:
Something must be seriously wrong.

Another likely-wrong theory: I remembered that htc said the display is calibrated against NTSC standards. Could this mean that the display is not only in standard color gamut, but also runs at NTSC/ATSC frame-time of 59.94 fps instead of 60fps ?
[HTC 10 Guides, News, & Discussion] ChronoReverse:
Seems to me that it's too consistently 58FPS to be that. I wonder if there might be a timing issue here such that it makes the phone think it's slightly slower.
[HTC 10 Guides, News, & Discussion] DeadPotato:
So after reading the whole post I have some questions. My screen is getting replaced on the following weeks and I'd like to know a couple things :

- Have any of you got a new Tianma and Sharp displays recently? Any changes on the known 'issues' on newer display batches?

- Are screen protectors affecting the chromatic shift in the Tianma panels or the visibility of the grid lines on the Sharp ones?

- Can KCal totally fix the chromatic shift once the screen has settled down? Same goes for Sharp ones?

- I think we talked too few about it or I missed the posts about it: how's the power consumption of both Sharp and Tianma displays compared? Is there one more efficient than the other?

Thanks for taking your time to reply if you do :)
[HTC 10 Guides, News, & Discussion] ilamaan:
So Tianma is the good one.

How do I figure out the panel before I buy? other than installing devcheck?
[HTC 10 Guides, News, & Discussion] Kisakuku:
Either devcheck or system info in download mode (have to be S-OFF though) or just by Sharp's distinctive digitizer appearance on light backgrounds.

Wich panel is considered better? I Have tianma and looks great... Better viewing angles then my htc m8. And compared to s7 edge of mu brother White looks More White on the HTC. On s7 edge White looks Blue. And i also couldnt use Polaroid sunglasses with my htc m8.

I dont understand why they Make phones this price class with different screens and different quality
[HTC 10 Guides, News, & Discussion] hamdir:
interesting but i dont think we ever saw a JDI HTC 10 in the wild, also does this suggest two variations on the Sharp panel controller?
[HTC 10 Guides, News, & Discussion] richii0207:
Screen polarization is due to the nature of LCD screen technology and has absolutely nothing to do with quality.
[HTC 10 Guides, News, & Discussion] 0kk0:
You are right. With quality I meant tint...striping different brightnesses etc.

But I have tianma and can see horizontal lines when I focus on it in the right angle. So Both Sharp and tianma Have striping? But no tint I can see. But what wondering if I should exchange for HTC 10 with a sharp display;)

Thnx!

What display model, how long have you had it and what have you done to reduce the chromatic shift? I have a tianma display and after my trip to Chichen Itzá (insanely hot place for my taste, it was around 41 Celsius and wasn't a specially hot day) the shift it's almost gone, so if you hadn't exposed it yet to heat and sunlight you could try that, it helped me a lot with my unit

after two months with the 10, i don't have any issues with pink/red tint or shift issues with tianma. using a custom colour profile from exkm and it looks very good to me. even on stock coolour and vivid mode its awesome. the owner before me had the device for a month. so yea everything is fine, yea sometimes lower brightness. but using manual brightness fixes it and the screen is superb compared to one x, m7, m8 and m9.

[HTC 10 Guides, News, & Discussion] PhiLee1998:
HTC has contacted me today and they say they have acknowledged the "PINK TINT" issue. The" elevation team" has said that HTC will fix this issue with a software update! I doubt how that's possible but they have acknowledged the tint problem nonetheless. Don't settle for mediocre quality when you're paying top-price for an equally top-notch device. People with pink tint, don't settle, never give in saying it's normal. You're being ignorant as a consumer and this practice leads to companies ignoring their quality. HTC's reputation is at stake, as soon as I sent them an e-mail stating I'm approaching the consumer court, they acknowledged the "pink tint" issue. I'm halfway through the procedure for consumer forum complaint but am halting it as HTC has called me up to stay put for the software update. DON'T SETTLE FOR YOUR PINK TINT, it's not normal. ﻿
[HTC 10 Guides, News, & Discussion] hamdir:
i didnt settle with it, we are on XDA right? a simple install of EX kernel with slight nudge of minus on the Red slider solved it

besides later batches has this much less in common, so its probably your bad luck (if you bought a new unit)
