Our users were reporting occasional pixelation when playing video, and we were baffled as to what the cause might be.

Then we realized that the following setting was the cause:
  • Charms -> PC Settings -> Ease of Access -> "Make Everything on your screen bigger"
Setting off: http://www.plexapp.com/mfeingol/bugs/win8-370/Normal.png
Setting on: http://www.plexapp.com/mfeingol/bugs/win8-370/MakeEverythingBigger.png

It's subtle, but clearly visible as a degradation in video quality.

Is there any way we can work around this at the app level?

Thanks.

Interesting issue. Is this with progressive download or smooth streaming?

Progressive download.

cf http://forums.plexapp.com/index.php/topic/61856-pixelated-video-at-any-res-transcoded-or-direct/ to see users reporting this, in case there's useful data in there. Feel free to ask questions there if useful. :-)

Can you please give it a shot with just a simple MediaElement and see if the same thing happens there? Just guessing but I'm thinking this is probably an issue for the Windows team. Ideally the rendering pipeline would be smart enough to not scale twice and lose data (which is what I'm guessing is happening based on your description).

Hi,

Can I just say this is not limited to the plex app or the setting Charms -> PC Settings -> Ease of Access -> "Make Everything on your screen bigger" (this setting is greyed out on the surface pro). I've been using some YouTube apps on the store (e.g. Youtube+) and all the videos I play on my surface pro have been downgrading video quality and videos are all blocky (even with videos at 1080p). The only work around is reducing my screen resolution from 1920x1080 to a lower resolution like 1600x900 then all the videos play fine within Youtube+.

Pretty sad that Windows 8 is having scaling problems with it's hardware that it was meant to be run on.

Really want another work around if possible, no point buying a laptop with a 1080p screen if you have to run it at a lower resolution.

Tim:

I just wanted to add that I've tested the "XAML media playback sample" from the WinRT samples.

I see the same pixelation effect when playing back media.

So I guess Player Framework is off the hook. :-) But how do we get this reported to the right people?

Yes I agree with mfeingol. I don't think raising the issue in the forums is going to help alone. We need to ensure this is reported to the right people.

If it is reported to the right people then I'm happy to help out as much I can, if they require configuration settings etc.
