Hi all,
I’m trying out the jetson with a very small monitor (480x800) and I’m running into some tearing issues
See here: PXL 20230629 080116891 LS - YouTube
One thing the video does not capture well is that there is no tearing where the mouse pointer is (the foreground?) but the screen tears otherwise.
Does anyone have any thoughts on how I could solve this issue?
Thanks
Is this a pure HDMI interface ?
Hey WayneWWW,
Yes, pure HDMI

Do you know what is the required pclk this panel need?
