...I have an AOC V19 monitor connected to a Dell Optiplex GX270 with Windows 7 installed. I tried to update the video card driver with the latest driver download but always get the message: "The best driver for your device is already installed. Windows has determined that the driver software for your device is up to date. Standard VGA Graphics Adapter." I used Windows 7 troubleshooter and got the message "Video Card Driver does not support Aero effects; update the driver." The driver provider is Microsoft dated 6/21/06. HELP! Can this driver be updated? Right now I can have 5 modes: 1024 by 768, 256 colors, default refresh; 640 by 480, 256 colors, default refresh; 800 by 600, 256 colors, default refresh; 640 by 480, High Color (16 bit), default refresh; 640 by 480, 16 colors, default refresh. The High Color looks best but is too big and 1024 by 768 looks good but the colors are off! Please HELP!!
