Hi,
Currently, I'm working on a SabreSD board with the latest BSP package (L3.0.35_1.1.0).
The problem is whatever I set for my u-boot settings the HDMI resolution is always 640x480.
Here are more information of my board.
1. When I typed "xrandr", I cannot see any interface except Screen 0.
2. When I checked modes of HDMI, it gives me following list.
When hotplug HDMI
U:640x480p-59
V:1280x1024p-60
V:1024x768p-60
U:2880x480p-60
U:1920x1080p-24
U:1920x1080p-50
U:1280x720p-50
U:720x576p-50
U:720x576p-50
U:1920x1080p-60
U:1440x240p-60
U:1280x720p-60
U:720x480p-60
U:720x480p-60
U:640x480p-60
My DELL monitor supports the resolution of 1280x720@60.
I checked previous discussions similar to this one, however, I didn't get any help.
Any commnets will be appreciated.
Sincerely,
Hak
Solved! Go to Solution.
Daiane,
Yes, I do.
Actually, I resolved this issue a few days ago.
After comparing my u-boot command lines with other ones, I found there's a redundant space in the video setting command line.
Anyway, thanks for your comment.
No, you should change your kernel command line. Please take a look on release notes, there you can see every video possibility.
Do you know how to change kernel command line on u-boot?
