|If the main chipset drivers have not been installed, that may affect the max resolution you can choose. |
XP doesn't have the drivers built in for most things that first came out after XP was first released, circa 2001, and it doesn't have some of the drivers built in for things made before that.
Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.
By default, Windows shows you only the resolutions both the video drivers and the monitor drivers support.
Installing the specific monitor drivers makes them available to Windows, but doesn't necessarily set Windows to use those drivers.
Go to Control Panel - Display Properties - Settings and make sure it says FX1500 on your model of monitor - if the monitor is set to Plug and Play Monitor or something other than your specific monitor model or model series, you need to click on the Advanced button on the Settings window and change the monitor drivers Windows is using to the right ones.
Click on the Advanced button.
Update Driver button.
