Display Problems

If the computer is on, but the screen is blank
Try pressing Fn+F1 to increase the contrast or Fn+F2 to decrease the contrast. (On
TFT displays, contrast control is not necessary and therefore is not available.)
Press Fn+F12 in case the internal display was disabled. (Do this three times to return
to the state you started from.)
If the computer is cold, allow it to warm up.
If the screen is difficult to read
Check whether the display resolution is set to its default setting—800×600 for 12.1"
or 13" displays or 1024×768 for larger displays. Check this in Start, Settings, Control
Panel, Display, Settings.
If you have an HPA display, try pressing Fn+F1 to increase contrast.
If the display refreshes slowly
Increase the amount of RAM that is allocated to video display (if your computer has
less than 64MB RAM). By default, a portion of your installed RAM is allocated to
video display: 4MB if you have less than 64MB RAM, 8MB if you have 64MB
RAM or more. (Using additional memory for video allows you to display more
colors: True Color with 8MB versus High Color with 4MB. However, using
additional memory for video results in less memory available for other computer
operations.) You can change the Auto default to either 4MB or 8MB.
1. From the Start menu, shut down, then restart the computer.
2. When you see the HP logo, press F2 to enter the BIOS Setup utility.
3. Open the Memory menu.
4. Select Video RAM Size.
