Trouble with LCD TV

[caish5]

Seemed to have made some headway.

# Modeline "1280x720_60.00" 74.453 1280 1448 1584 1696 720 721 724 746 -hsync +vsync
Modeline "1280x720_60.00" 65.00 1024 1048 1184 1344 768 771 777 806 -hsync +vsync

After we changed the modeline to something we know works, it set the resoultion to that, 1024x768@60. So if we get the modeline for 1280x720 right it should work, i hope.

Why are you using NoHorizSyncCheck, NoVertRefreshCheck ? Does the problem improve without them?

Its also possible that your hardware just cannot run at a non-60Hz refresh rate.

Thanks,

Were finding that without them, the debug log told us first the vert, then the hor was out of range of whatever they were set to, but that was probably down to the modeline being wrong.

Ok, went through generated these modelines in exactly the same way... using value from manual.

640x480, 800x600, 1024x768 all work perfectly.
1280x720 refused to work, and i have no idea why.

I know that 1280x720 displays in windows fine, so the monitor can handle it.
I'm pretty sure the modelines are correct as they all got generated the same way, and the first 3 work.

The only thing that has changed is that it has gone from 4:3 to 16:9.
