I recently purchased two flat screen monitors and have set them up as a dual screen using my radeon 9200 graphics card. However on one of the monitors the text seems blurred and less clear than the other, as far as I can see they have the same driver and settings both in display in control panel and with the configuration on the monitor itself.

Are they both the same model? If not, try using the native resolution for each one.

LCDs tend to be funny like that if you are not using their native resolution...

your using a standard connection rather than a DVI connection.

you need to tune your screen, most LCD monitors will have a tuning tool.

this will take you step by step in adjusting the phase of the monitor - it sounds like its out of alignment slightly

Why don't you switch the cables to the monitors and see what happens. I mean take the cable connected to monitor A to B and do the same from B to A.

I know it is kinda lame but try it.

Looking at the specs for the Radeon 9200, the design should work well for dual screens:

Dual integrated display controllers to drive two displays simultaneously with independent resolutions and refresh rates

But how are you connecting the displays? Both with DVI or just one, with the other one being a VGA connector?

Looks like a good screen otherwise.
