New Monitor does not work on some resolutions

January 19, 2011 at 19:10:36
Specs: Windows XP, P4 2.2GHz/1GB
I am running a Gateway 700XL with a Radeon 8500DV graphics card installed in the AGP slot. Connection from the computer to monitor is via DV cable. The original Gateway FPD1810 monitor runs well at all resolutions (about 20). I purchased a new 24" widescreen Dell monitor (model# P2411H) and it works correctly on only 4 resolutions (800x600, 1024x768, 1152x864, & 1280x1024). When I set the resolution to all others I get horizontal flickering (interlacing) and the monitor intermittently blacks out just by moving the mouse.

Dell has replace the monitor and states that it is the video card.

Can you tell me what the problem is or can you tell me what video card can be used to work on the widescreen mointors. The motherboard is a Lexington 3.

First of all you need to verify that Windows has identified your 24" monitor. All the resolutions you list are 4:3 ratio. Your 24" has 16:9 ratio. Besides that, LCD displays are best run at their native resolution. In your case that is 1920 x 1080. All other resolutions are extrapolated and will not look as sharp.

You may need to update your graphic drivers. If the 8500 can even display those resolutions the monitor must be identified by Windows. A generic PnP monitor listing probably won't allow you to select any 16:9 resolutions. To repeat, run the 24" at 1920 x 1080 only.

According to Gateway documentation your old monitor only supports 1280x1024, 1024x768, 800x600, 640x480. See the link below for specs on the old monitor.

See the tech specs for the 24" Dell at the link below.

The Radeon 8500DV is at least 8 yrs old & the last driver available is over 4 yrs old.

The native resolution for your monitor is 1920 X 1080 at 60Hz. Anything else will look like crap. It's time to upgrade your video card.

I appreciate your feedback and it sounds like I need a new video card.

So, I have an older computer (Gateway 700XL) which has a Lexington 3 motherboard with PCI slots and an AGP slot. Since my current graphics card is in the AGP slot I guess I need a graphics card for and AGP slot. I found one through Dell which is a EVGA e-GeForce 6200 256 MB DDR2 AGP 8x Graphic Card for $39.99.

My question is will this work in my machine and will it solve the problem with the widescreen monitor not working?

Also, if this graphics card will work would it be better to hook up the new monitor with the DVI cable or the VGA cable?
