My desktop with video VGA and DP outputs is connected to an 1680x1050 display, with VGA and DVI inputs only. My TV is 1920x1080 and it has HDMI inputs only. A DP to HDMI passive cable arrived yesterday and I was able to do test on the TV. Youtube plays 1080 fine in chromium when connected to TV: less than 1% frame drops, max 38% cpu load for chromium in top. This is not happening when I connect the desktop to the display ( VGA or DP-DVI adapter): almost 10% frame drop and aprox. 89% cpu load. My thinking is CPU is used a lot to do that crop from 1920x1080 to 1680x1050. > I'd suggest to check where is spent most of the CPU time, in mpv or in > Xorg?

If I use mpv to play youtube link, the results on TV and display are the same or better, looking like youtube in chromium on TV. Using -vo x11 is using almost 55% on cpu and I get mpv complaints in console about performance. Is there a way to replace HTML player from chromium with mpv and play the stream inside the chromium page on OpenBSD? Thank you.
