Getting out of my depth now. I don't work in related field or even have a videophile gene in my body. Is it a 4K BR disc or 1080p? Maybe the scaler chip in the BR player is trash?I am trying to wrap my brain around this. If the 4K video is really 720P when scaling apps 300%, then I can't tell the difference between 720P and 4K with no scaling?
But if I play a bluray player, not through windows, and set it at 720P, I can sure see the difference on a 4K tv
Delivery still on for Monday but who knows with the weather going through the easterly region of the USA from whence it is has been shipped (NY).The HP RX 550 2GB should have DDR5 , run 4K at 60Hz, and is supposed to decode VP9 with the better drivers. I am not sure how to test VP9
Programmable shaders can be used for some of the decoding like post-processing but not all of it and at considerable performance cost compared to dedicated fixed function decoding units. In some aspects of decoding using the shader resources is slower than just offloading to the CPU. This is why the GPU has dedicated video encode/decode processing units, which VP9 content cannot exploit in this case. But H265/HEVC runs wonderfully (because it has explicit support in the video processing unit and driver).I don't know what this means. Shaders are within the GPU, right? as is the video decode path? Where does one see the video decode path?
I think you meant 30 or 60 fps, not Hz.My GPU cards are both 30hz, the 4K TV is 60hz, youtube 4K is usually 60hz. I bet things would smooth out with a 60Hz card.
Youtube is saving on bandwidth. Either the video they have on their servers isn't full 4K or they are transferring a lower res version to your PC because they have determined that your internet isn't fast enough.Now the youtube stats say it is displaying the 4K video at 640X360*3.5, so youtube "knows" the 350% scaling in effect and does not alter the 4K image , so if I go full screen there is no difference.
I know but he said his 'cards were 30hz' and videos don't have a refresh rate expressed in Hz.
The bluray player will downscale the video to 720P and then the TV's upscaler will try to stretch that 720p over 4K worth of screen real estate. The result will obviously be a mess. Most 4K TV upscalers work best with 1080p video.But if I play a bluray player, not through windows, and set it at 720P, I can sure see the difference on a 4K tv
Technically yes but nobody customarily describe the video's frame rate in Hz. And what does a 30Hz card mean?How to watch at high frame rate To get high frame rate playback, watch a YouTube video at a quality of 720p or 1080p. In the quality menu, high frame rate will be listed next to the resolution. support.google.com
Hz and FPS are same and youtube supports 1080p60 videos.
Possibly some really old card that has a video output port that can't do any better than 30Hz.
