December 11, 20232 yr When connected to some PC monitors, the image is larger than the physical screen: about 20 pixels at the top and bottom sides, and 50 pixels at the right and left sides are missing. This happens as soon as the board boots (without logo), the start of lines are truncated, and this also happens on text ttys (Ctrl + Alt + F1..6). I guess it's about a boot env variable, but I could not find it.
December 22, 20232 yr i live with that on samsung old 26 led tv. It doesnt have image adjust / auto settings in tv menu, so its menu option. in sway or gnome i dont see upper bar with time and volume settings , but i can click on edge and menu shows up. On sway also setting floating windows for apps is usefull. Edited December 22, 20232 yr by nihilowy
December 27, 20232 yr Author The issue seems solved in kernel 6.7.0-rc4. But other issues appeared (among which no more sound). For now I'm staying with 5.1.160.
December 27, 20232 yr I had the same issue with an old Samsung TV/monitor and use a HDMI->VGA adapter as workaround.
December 28, 20232 yr Have you redirected the sound to hdmi in the settings? Default send to the jack.

Contrary to 5.1.160, the sound output menu is empty when booting with 6.7.0-rc4 On 12/28/2023 at 12:44 AM, royk said: I had the same issue with an old Samsung TV/monitor and use a HDMI->VGA adapter as workaround. I was considering a DVI adapter to stay "digital". But your solution is bolder! On 12/22/2023 at 10:29 AM, nihilowy said: i live with that on samsung old 26 led tv.

I looked in the edid informations which appear in: /sys/devices/platform/display-subsystem/drm/card0/*/edid I found "wxedid" to decode and edit the edid (it's a tricky binary format). The relevant "timing" informations are identical between the two monitors. I tried editing the edid and writing it back: no change. Nor does it seem to change anything when given as a boot parameter.
January 4, 20242 yr @bolet75 Yeah HDMI -> DVI didn't work for me either. About the audio, HDMI audio doesn't work yet on the mainline kernel, jack input/output would need to be set correctly in the dtb, last time I checked it didn't work either: https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/mainline-status.md Edited January 4, 20242 yr by royk correction
June 24, 20242 yr Author The problem is gone with another monitor, still on HDMI connection. As I'll keep that new one, I won't be able to test this issue in the future. As I said early, the issue is solved in newer kernels (not yet in 6.1.43 though which I upgraded to before I switched the monitor). So the issue looks like depending on both kernel version and monitor model. The fix which happened in recent kernels probably isn't worth backporting.
