Why is the video not 1080p when recording certain online videos?¶

CASC can only record to the resolution of the video displayed on the mirrored screen.
If the resolution of the online video played on the mirrored screen cannot reach 1080p, then CASC cannot record to 1080p
Some models of HDMI cables, HUB does not support certain online video platforms. These online video platforms do not output 1080p to these displays. But only outputting low resolution displays.
Suggest users to replace cables, HUB, or directly connect the monitor to the computer. And ensure that when playing online videos, the screen can display 1080p images before using CASC for screen recording again.
