you could lower the black level of your tv, so you don‘t see those artifacts in the dark areas.
Amount of 4k videos on youtube movie#
remember, one already heavily compressed blu-ray 4k movie has about 66-100gb, whereas a youtube video of the same length has about 6-10 gb. Those blocks are compression artifacts - youtube’s compression reduces the original file by a factor of - i don‘t know 100? - in comparison to an uncompressed 444 stream - so something‘s got to give. but most youtube videos are in 4:2:0, 8 bit chroma-sampling anyway, rec709 should work fine, i guess. Rec 709 is the color space for hd - if you want 4k hdr, you need to set something different (eg. even then it‘s probably easier to do this via displayport (and adapter, if refresh rate - there should be no difference in sharpness between 60hz and 30hz, but if your tv interprets the refresh rate (in combination with the resolution) wrong, or one point (cable, tv) is not compatible this could result in a blurry picture.

you need a hdmi 2.0 compatible adapter, tv and cable. Does not matter if the videos are in 1440p HD or 1080p HD.Īfaik some adapters - like apple‘s - are limited to 30hz. black or dark suit people are waring) shows up like blocks of dark images. Under Display, what color display profile should I choose? I just use HD 709-A by default. Does a adapter leads to some unclear video images when expanding the youtube playing window? It is like watching things with a glass that is not completely clean.Ģ. That adapter outputs 30Hz so it causes the lags in dragging the mouse pointer and windows. not sure if it is 2.0 or 1.0) but there is no change in my situation.ġ. I have also tried another HDMI cable (bought many years ago. It shows that 3840x2160p 4K, 16:9 on the screen.

I pressed the Display button on the remote controller of my Sony 49X900E TV. Under Display, I can choose different resolutions.
