Take 1 monitor. Works perfectly prior to being attached to a new system.

Connect monitor to new system - corrupt image at bios & after windows loads... not that you can tell when windows loads.

Test new system with another 2 different monitors, works perfect.

Test monitor with another system, works perfect.

Same leads, same GFX card etc.


lol.. I'm confused. :crash:

Maybe have a look for a bios update, i know its a bit mundane but could be worth a look.

Bios is up to date.

The system works fine, it's just the monitor that's being quirky but I've tested the monitor on another system & it works fine. Even checked the cable & that works fine too.

Monitor works on every system bar the one it's meant too...lol.

The pc works with every monitor apart from the one it's meant too...lol.

:chuckle:

Maybe turn the monitor on/connect it once Windows has booted up and see if that works :p

Done that too... `tis a strange one that I've not come across but taking a spare monitor when I take the `odd` monitor too.

Checked the refresh rates??, if the GFX is set higher than the monitor can cope with it can corrupt the display

Sure it's set to 60KHz.

It's the same GFX card that was in the machine previously & it worked on the same monitor.

lol

Try the alternate DVI method (if available) in the GFX advanced menu; or untick it if already selected.

i HAVE had exactly the same problem and it was a GFX card setting, but it was so long ago I cannot remember exactly what!

What res are the 2 monitors?

I would place my bets on the Graphics Card, and I would take a punt that its the graphics card memory, or part of it at least.

This next bit is purely speculation, but I would guess that the two monitors are running at different default res's, and the one that doesnt work runs at a higher res. That would make the video card use more memory and possibly push it into the area of memory which is bad, and so would corrupt the display!

As I say, thats a guess, but it seems like you've tried most of the obvious, so I'm trying to think out of the box a bit :)

One other thing I remember, setting the GFX bandwidth in the bios to zero helped with one card I had, it had a large amount of memory and didnt need to share system memory, and it was the sharing that was buggering things up.

I appreciate the theories but we tried the gfx cards in the system they are in now with my spare 17" monitor & they worked perfect.

Also tried with another 15" monitor & worked perfect.

Hopefully it's just a daft refresh rate issue but I can't see it myself but will find out :D

What is the res of the new and old monitors though?

Actually, you can check if its a refresh rate issue etc by starting it up in safe mode. If it doesn't work in safe mode, you can eliminate it being a refresh rate problem. If it doesn't, it could still be any of the other solutions listed above.

Just to let you know, I had a very similar problem (pretty much identical) to the one you describe on another computer. It turned out to be the solution I suggested.

It's either the refresh rate or a dodgy VGA/DVI adaptor.

Soon as I get it tested I'll let you know :D

And the winner is......

Dodgy DVI/VGA adaptor!

Bloody thing :D
