What type of input does the new monitor have? If it has DVI and the video card does not, it's your choice. Get a new video card with DVI or use the regular monitor input.
What is the native resolution of the new monitor and will the video card provide it? If not, back to the above.
I have a 3 year old Media Center desktop model m1050y with a basic HP 17" CRT monitor; running Windows XP. I'm about to upgrade to a 22" LCD monitor but I'm wondering if I need a new video card in order to take full advantage of the new monitor? I am not a gamer but I'll be doing some photo and video editing, as well as watching TV. I am currently using the graphics card that came with the PC: a 128MB DDR ATI Radeon X300 SE with TV-out and PCI Express slot. Do I need something with DVI? Any advice? Please let me know if there is any more info I need to provide about my machine.
