I have a dual-monitor system, both monitors are the Sony GDM-F520 21". My video card is Nvidia Quadro4 900 XGL (made by PNY) which is an AGP card with two DVI output, but can be converted to analog (this is how I connected to the monitors).
The problem is the color on the two monitors are different, one is cooler than the other, and no matter how I change the color temp. and gamma, brightness/contrast or RGB values, I can't seem to find a way to match these two monitors. So the question is how to match the colors on the two monitors?
These monitors are $1600 each, I'm sure It's not the monitors causing the problem, since if I switch the connections, nothing changes (color stay the same). I had other Nvidia card which had same problem, so it's the output of the video card making them different. It's a problem, but the card is not bad (so unless there isn't a way to fix this I'm not returning it). I'm going to call the tech. support, but if anyone can save me some time, you will get an A.
If you tell me some software can do this etc. please make sure it works. At least you should have successfully solved this kind of problem before. Thanks.
