Hi all,
i trying to set hdmi script.fex to 1024x768 resolution but after script.bin generation and reboot, resolution don't change.
Is there a procedure to do it ?
i have a 4:3 monitor with hdmi input so i see stretched image using 1024x600

thanks

I solved my problem:
as describe this post http://www.the-greathouses.net/blog/2013/03/setting-pcduino-display-resolution/
setting screen0_output_mode = 27 monitor is setting to 1280x1024p60.

So i modified change_display.sh script to set this resolution

i added at line 54 and line case 27 at line 260

bye

Thanks, that was exactly what I needed for my old Eizo L568 LCD Monitor which didn't accept the default HDMI modes.

I simply added your sections to the current change_display_a20.sh and all works well.

I only get a static purple/blueish border approx 2 pixels wide on the left and on the bottom of the screen. Any idea how to get rid of this and center the active screen correctly?

Hi Heinz,
have you tryed latest Debian Image (R5) ?
Also i had some strange video problems using first images but from R3 it work fine.

Yes, I'm on R5 (this is my first, brand new board with an SD card from the shop).

But it's only a small cosmetic issue; HDMI output in general is much better than VGA on my monitor.

Are you sure the original resolution was 1024x600?

I have a display with that resolution, and i can not find a way to get it to use that resolution...
