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
