Are all LCD Monitors Compatible with Linux?

Ken Heng asks: "I'm shopping for a 15" flat panel LCD monitor. But since a lot of these come with their own drivers, I'm afraid that when I get one, I may be unpleasantly surprised if they don't work with my Linux system. Or if they work (yes, I have seen in Xconfigurator, you can choose the LCD panels with different resolutions), they may not be fully functioning. FYI, I'm using RedHat 6.1 on an Intel Pentium II platform. Please advise if anyone knows about this."
