Problem with Sony CPD-520GS

[Zephyrious]

I can't get my monitor to display anything higher than 1024x768, on my ThinkPad T40 (Radeon Mobility 7500 32Mb) I'm fairly certain it's not the laptop. Can anyone give me some advice?

Thanks in advance


Matt.

You may have to install drivers for the monitor.

 

[Zephyrious]

Will do, note that CPD-520GS comes up already in Display settings, but I'll give it a shot anyways, thanks for the tip!

• Sure enough, I found a driver, I'll post again as to whether it works or not later. Thanks again guys!

I'm still having problems... The screen goes all funny and basically it looks like the monitor doesn't support the resolution... but I know it does... any other suggestions?

Have you got a 'quality' lead going to/from the computer/tv?

 

[Zephyrious]

Yeah... It's a decent VGA cable... however, there is a VD-Z3 acting as a switch... I'll check that out and let you know. Thanks for the tips!

Try adjusting the Refresh Hz higher or lower....

Tried that, didn't work, messed with the Composite/Vert/Horiz sync, didn't work... I guess I'm just screwed. Maybe it's time for an LCD

Could you make sure that you have allocated another 32MB in BIOS from RAM to the Radeon before you surrender.

While you may be changing the resolutions you may be changing the resolution for the laptop display. New Radeon laptop graphics have the ability to have different resolution settings for the laptop screen and the VGA out to the monitor. Double check, this is a guess but I have seen it cause problems before

Not exactly sure what you mean... I checked in the bios but there was no option to allocate more memory to the radeon as far as I could tell.

Please explain!

I was under the impression that the card is 32MB but is able to utilize another 32MB from system RAM.
I haven't dl'd any manuals, but if you can do that in BIOS, then fine, if not, then there may be a utility to do it.

I downloaded the omegas for the radeon 7500 and low and behold... same problem @ 1280x1024. 1280x960 works though, and wasn't there before I installed the omega drivers, and that's good enough for me. I even got it working at 1920x1080 @30Hz. Thanks!

 

[montag451]

30hz???

Does that give you a headache

 

[Zephyrious]

1920x1080 @ 30 Hz which is (I think) 60 Hz Interlaced, which is the native refresh rate on any TV, and more importantly, the refresh rate of 1080i, or true progressive scan, television. I have an HDTV! 1280x720 @60Hz works great (720p) too! I have an HD ready monitor, and a VD-Z3, watch out!
