Hi I've been doing a few videos about the ASUS TFP and did a comparison video today and noticed something which kind of explained in my head why I sometimes think the screen is flickering (not the reported type) and why it sometimes feels like the brightness is changing ever so slightly.
You only need to watch the first minute but you can see the screen flickering whereas the HP touchpad doesn't flicker at all. Is this due to a ropey screen refresh rate? It's like when you watch old news reports with CRT screens going mental (although not as bad). I also notices that the contrast and colours actually seemed better on my touchpad which was odd. Are there any apps out there to tinker with contrast and colour saturation and stuff?
Cheers,
Felix
P.S. how do you embed youtube videos? Do I need an X number of posts?

I don't watch Netflix on my phones that much, but i was bored today on lunch and decided to watch a Doctor Who episode. I noticed that the video playback was very dark and grainy (brightness all the way up). I'm sure others have noticed this as well but i couldn't find any posts about it. I know that the phone is capable of 1080p playback so i fired up an HQ youtube video and it looked anything but high quality. The pentile display could be the culprit in this case, but it seems like it would be the gpu because it still seems like the resolution is low. Thoughts? Comments?
Hd on my phone looks great. I won't deny the pentile display leaves a lot to be desired, but not on pictures and videos. At least for me.

The graniness during playback is a negative characteristic of the pentile display that some people notice and others don't. The graniness is greatly reduced (even eliminated) when you turn the brightness down. I would recommend turning the brightness down to the lowest setting. The photon's display is so bright that you will probably never need to turn it up.
I noticed the dark grainy too, I thought it was just the program I was watching.

I've tried that and the quality was a bit better, however the contrast ratio on this phone is so great that the darks are dark as hell. I don't notice the pentile "screen door effect" unless i am looking for it, or if it catches my eye for a split second. Oh well, i still love the phone, i guess the Iphone's retina display spoiled me.
I dont think its the videos or the software playing the video. Its the Display Technology Moto chose to run with. Ive been on 30+ android / windows mobile / ios phones and this phone has the worse Display I have ever seen.
Its great that the display is in QHD res but the colors are awful on this phone. Coming from Evo 3D / Nexus 4G those 2 phones alone have bright colors. Especially the Nexus since it uses a AMOLED screen.
The photon is a GREAT phone but the display is just crazy bad. All my pictures / videos don't have enough color to them which then give it that grainy look. Shouldn't have to turn brightness down but even while doing that, there is still grainy picture.
Ima hold on to the photon for a lil while longer and then might jump to GSII.

Oh boy, i think i can smell whats coming... sorry for starting Display War II.
The blacks being to dark is black crush. This can be fixed with software. Hopefully something like voodoo will come out to allow us to make these changes.
Also note that display also has white sub pixels in addition to RGB which is supposed to increase the perception of brightness without being brighter. At least that is what i understood.
Last note when watching netflix, 4g and wifi seem best. Not sure if the limited 3g bandwith could be lacking the addition black information making the blacks crush.

Black Crush. That is exactly what it is. Everything else in this phone is near perfect. GPS locks in seconds. Speaker for music is loud and clear. Camera takes beautiful pictures. The camcorder is beautiful also at 720p 30 frames per sec. Phone is beast. Only draw back i see is the display BUT phone is nice and bright while outside in direct sunlight. As for the display i guess thats when DLNA and Micro HDMI come in LOLOL.
With the significant drop of SuperAMOLED quality control or just plain bad luck on my end I've decided to call it quits and look at other screen technologies and suffice to say the rumored Tab 11.6 is peaking my interest and probably that device will come with PLS.
I've had a chance to compare the Tab10.1 and Ipad2 but I really didn't do so extensively, I was comparing the TF201 , Ipad2 and Tab7.7 and after a lot of testing I've concluded that SuperAMOLED only offers better blacks, the rest is just a subjective preference like color saturation, even viewing angles are superior on the TF201 and Ipad2.
My primary usage is video playback then web browsing, Im also particular with white tones across all brightness levels and with my current Tab7.7 the white tones at low brightness are just horrible compared to the TF201, Tab10.1 and Ipad2
Anyone with extended experience on the said devices can share their opinions between the PLS on the Galaxy Tab 10.1 vs the IPS on the Ipad2 or TF201?
BUMP for my post, how does the Tab 10.1's screen perform in terms of movie viewing?

Pretty good when the brightness is turned all the way up, This being on Dice Player @ 255/255, Better contrast and color, I think Bravia engine can be added to enhance the colors.

about 95% of the time I use the device at the bed room, so 0-33% brightness might be up my alley. When you say better contrast and color is that in comparison to the Ipad2 screen ?

I watch a lot of series and some movies on my Tab while in bed and imo it's pretty great (especially when they're 720p ). It's almost always at night so no problems with the sun shining on the screen though. With the sun shining directly on the screen, I doubt you could really enjoy any movie ...
I have my brightness set somewhere between 50-100/255 on Dice Player, depending on the movie and if I have any lights on in the room.

Yeah around daytime it's best on 255 but around night time I keep it to 150 or such, any higher at night is like an alien abduction
Hmm on a superamoled screen i keep it at 46 only. But that doesnt really matter as long as the whites in web pages remain white unlile oled.

I've been wondering the same too, On my desktop it shows XDA is creamish/pink but on the tablet it shows that xda is white o.o

Strange, it shows the same color for me both on computer and on the tablet. I *did* have the "white xda" problem in the past though, both on my desktop, laptop and tablet. Thought it had something to do with a faulty .css or something similar though, haven't seen it in a long while now.
What I mean is on low brightness levels the white tones on the SuperAMOLED screen becomes either grainy or may turn into yellowish,pinkish or blueish depending on the the screen you've got. Though movie quality is great I also noticed it makes an actual scene darker crushing detail.. Samsung tried to fix this with a different gamma profile on the Galaxy Note but it ends up giving blocky blacks.
I've come across a store demo unit and sadly I cant transfer over my media files, BT just takes to long and the Tab10.1 has no wifi direct.
Is backlight bleeding a common issue on the pls screen?

PLS is plane line switching where as ips is in plane switching. The only difference between the Displays is the light thourough put is higher in Pls that ips hence the more vibrant colors and brighter backlight

Hey,
I've just bought a V30 today after my Nexus 5 started to have some issues to hardly use it as a daily driver.
After spending some time on it, I've noticed that the display is quite blured if you look close to it (it can be seen mostly on white backgrounds). It looks like watching a 480p image on a 1080p display in full screen. Everything seems to have lower resolution than it should have (note that I've tried to adjust brightness and resolution but it seems to be hardware related)
Is this normal? Is it like this for all oled displays?
Thank you for your answers

Are you talking about grainy looking? That happens on very white backgrounds in my experience. Shouldn't be blurry though. Any chance you are able to take a picture of what you are talking about specifically

Yes something like grainy, mostly noticeably on 50% brightness and white backgrounds but also on other colours (like there is a another layer between the oled screen and a display). Should I sent it back ?
@Klyno
From what I've read on the matter it seems to be just an inherent "quirk" for the V30s P-OLED display (kind of like the "Blue-shift" effect that happens when viewing the screen at a certain angle and beyond). There was a thread on here somewhere about the display that some people mentioned this. You can try exchanging but I'm not sure it will help. Maybe someone else can chime in ( @ChazzMatt frequents the V30 forums quite often so I'm sure he can direct you to the right thread). Maybe try the display thread under real reviews category

Hello,
Did anybody noticed in the camera app that the screen is kind a flickering in some situation?
I am not talking when you are taking pictures or video, but just before that
It is like you can see your screen frame rates
I am not sure if this is normal and if it is a camera thing or a screen thing
Happens on a lot of phones. Usually it's down to the lighting. Pixel 3 is terrible for this especially when indoors.

Hey, when using the mobile phone to shoot TV, computer and other screens, found that there are vertical stripes or horizontal stripes flashing. Because the screen refreshes the screen at a certain frequency, which is beyond the range perceived by the human eye. However, the camera head can capture it. If the scanning frequency of the camera does not match the refresh frequency of the screen display, stripes will appear when the screen is photographed. This is normal.
Hi all,
I would like to get some feedback on the AMOLED display quality in regards to uniformity when displaying a grey screen?
Did Samsung improve anything here or do the AMOLEDs still have clouding issues and the displays are not really uniform?
I have a Tab S3 and Tab S4 both with some clouding visible especially when displaying grey and dark grey.
Thanx in advance,
am
From what I have seen the AMOLED display on the SGTS7+ is actually pretty good for watching videos, the colors are excellent and so are the blacks.
It's an excellent display, as long as you use it over 30% brightness
As soon as you dive under 30%, it's a color-calibration sh**show, with a huge green tint issue (pretty much the same thing for any high-refresh rate displays of 2020. This issue was fixed by the following generation of displays, with the help of LTPO technonology)
I use it 5-6h per day as laptop replacement, and it's a blast during day time. But as soon as I want to watch movie at night time, the green tint forces me to push the brightness higher than my eyes wished.
The severity of the green tint will vary from one unit to another, but no one is spared.
