I have a Gateway monitor that has a lame resolution of 1024x768. It has a refresh rate of 60 hertz. I also have a GeForce 8500 GT, and an Intel Core Duo which runs at 1.6 ghz. I read in another article on this site that the monitor can be the cause of my problems, which are that my computer displays most video games with jagged edges, and it can't run any dynamic lighting at all or it lags. Some games it has a hard time running are Ghost Recon Advance Warfighter 2, and Stalker: Shadow of Chernobyl. The dynamic lighting is the biggest problem. Could my monitor be the cause of this?
