We are working on OMAP35x EVM Revision D board with TI PSP SDK 02.01.03.11. We tried to display

video on DVI port. We found that DVI display works on LG, DTI and Accr monitor but it doesn't work on

HP and JVC monitor. Our settings is : omapfb.video_mode=720x480MR-16@60 omap-dss.def_disp=

"dvi". We need a very urgent help on this. Any help and suggestion will be greatly appreciated!

When you say "doesn't work" what exactly happens? Does the monitor report an invalid signal, or do you get a corrupt/blank display?

if you can e-mail me at sclynes@ti.com I will send some test code which will directly configure the DVI output through direct hardware register programming to help determine if this is a software or a hardware issue.

Just out of curiosity, do other resolutions work on all monitors or are all output resolutions broken?
