Interlaced CGX screenmodes
« on: July 04, 2007, 09:25:56 AM »
Any CGX screenmode above 1024x768 on my A4000 is interlaced. Though 1024x768, which is not interlaced, is rock solid, the interlaced higher-res screens are a bit flickery. Is there any way I can configure this out, or is it a limitation of my monitor?

I'll try my Thinkpad at the same resolution on the same monitor and see if I get the same flicker. If I do, at least I'll know there's nothing I can do about it. If I don't, then I'll have a play in CGXMode and see if I can reduce or remove the flickering.

Thanks

I have already tried setting it to normal instead of interlaced but when I test the screenmode it's stretched double height. I suppose I can compensate for this by changing the frequencies?

Ok I set the screenmode to Normal instead of Interlaced and found a frequency that worked, and my display is rock solid now :-D

Thanks guys
