You'll be better served if you get a new video card. That being done will provide the typical DVI/HDMI port(s), which will readily support your new LCD monitor. That way the resolution options will cross-reference and be a go. Yes, your Dell PC will support this, I assume you have either PCI or PCI-e type slot to mount new video card. If this AGP, then look for a PCI type video card. Your specs will show what you have. I also suggest you get a 512mb video ram card for a good fit on your system. While, you can install more or capable video card, then the PSU becomes an issue as you need better PSU to support the newer video card. Notice, you can't do one w/o the other upgrade(s). Your Dell 4500 is dated and thus you deem what cost can be permitted.
I have a Dell Dimension 4500 with XP, Video card NVIDIA GE Force4 MX 420, the system has TV out if that makes any difference. My old CRT monitor is on its last days.
Is is possible for this system to support a newer model LCD monitor, and have a clear image? I read where the max resolution is 1920x1200. But now it is set on 1024x768.
Any help would be appreciated.
