Windows 7: Can't change screen res/video mode not supported

Hi I just installed Windows 7 over my XP-SP3 os. I can't change the screen resolution. When I go in & select 1024x768, my monitor goes black with a square box that says "Video Mode Not Supported". I can select other screen resolutions but that error comes up & when it goes away, my selected resolution doesn't save.

My monitor is a Samsun 173v.

Did you install your graphics card drivers? Also the monitor driver itself? looks like they may of stopped with the monitors drivers on your particular monitor back in 04' from there website

I did install the monitor driver & the utility drivers that came with the computer a long time ago. I assume the graphics card drivers were in there? I also went to devices & updated all drivers... only 3 actually downloaded updates & the rest were good. However that didn't solve my problem.

It also gives me that same error everytime I reboot or turn the pc on & then resumes the normal screen when Windows is loading the desktop.

As you said drivers that came with computer a long time ago, You need the newest drivers that are for windows 7 especially the graphics card driver. What graphics card do you have, can you fill in your system specs more.

I've already gone into Devices & clicked Update Driver for all devices - a couple updated & the rest said they were already current. Problem still persists after doing that.

How do I find out what my graphic card is?

Welcome to seven forums Brennie369 :Type DXdiag in the search box. Open dxdiag, and click on the display tab. Fabe

OK we have to do it this way. Go to device manger>click on display adapter>properties>details tab>drop down menu>hardware id. Copy and paste the hardware id string. Fabe (edit) it would also help to know if you are trying to install 32 bit or 64 bit as you only have half of the minimum ram requirements for a 32 bit system. Another important piece of hardware is your motherboard, if it's a Nforce 2 or 3 no way.

Ok here's what I get with that:

It's an SIS 651 Graphics. Their are some 2009 drivers for windows XP. in microsoft Update catalog, which you can try and install in compatibility mode Compatibility Mode Choose the most current driver from the catalog>click on add>save to basket>click on view basket >choose location to download>download. Go to device manager click update driver>browse>let me pick>have disk>point it to the place you downloaded the driver and install. I really don't know if it will wotk, but good luck.
