1280x1024 = 1,310,720 pixels per screen. 1440x900 = 1,296,000 pixels per screen. The latter resolution is a little less. There is a simple formula for calculating how much video RAM a card needs to support specific resolutions. Multiply the total pixels per screen by the number of bytes per pixel. Then convert that number to megabytes by dividing by 1 megabyte, (1,048,576)
If you want to run at 1440x900/24 bit resolution
1440x900 = 1,296,000 pixels x 3 bytes(24 bits) = 3,888,000
If my Control Panel maximum resolution is 1280x1024 resolution will it be compatible with a 1440x900 resolution LCD Flat Panel monitor? The aspect ratio is different, as is the maximum resolution, so I am trying to find out if I should buy the new monitor. Or do I have to get a new video card or something else? Thank you for any help you can offer.
