I can't change my screen resolution in the control panel and I can't find any drivers for a Compaq SVGA Color Monitor. All of my options are greyed out.

That sounds as though you only have the "Generic" drivers installed? Go to the Motherboard or Video Card manufacturers web site, and download the video drivers and install them, Then you will be able to adjust you setting. BTW, have you tried right click, desktop, choose properties, and adjust the slider, Or if vista display settings, or can't you do that?

Heat from monitor

The monitor,screen,adapter or display of a computer is the primary user interface. Monitor problems are some of the most common computer problems since the voltages inside a monitor can be as high as 10 KV. Many of the problems can be fixed yourself by simply changing the settings but in a few cases you may have to either replace or repair the monitor.
google_protectAndRun("ads_core.google_render_ad", google_handleError, google_render_ad); How to troubleshoot and fix computer monitor/display problems
1. The monitor/display flickers
Check the refresh rate. If the refresh rate is 50 Hz/ 60Hz (depending on which country you stay), it can be affected by interference from electrical power signals like those from fluorescent lamps . Increasing the refresh rate to 72Hz is recommended , since higher refresh rates reduce eyestrain and headaches
2. The display works fine initially, then after some time there are black lines on the screen and then the display disappears
There is a problem with the copper windings in the CRT monitor which are getting heated. It is better to replace the monitor
3. For a new monitor, you get a blank screen or distorted image.
Many monitors, especially LCD monitors, can only handle resolutions which are less than the native resolution, so set the resolution at the native resolution only. The native resolution of a LCD display is lower for smaller LCD screen sizes, typically 1024 X 768 for 15" LCD. CRT monitors have a better resolution than LCD displays
4. The display on the monitor is not steady
This is a result of power system interference from users of the power grid, particularly UPS, power tools and heavy machinery. Try changing the position of the monitor.

5. There is a shadow on the images on the display
Try reducing the contrast setting on your monitor.
6. Monitor becomes blank occasionally
Could be a problem with the display card, check with another monitor. The monitor display cord and power cable should be fixed properly and there should be no loose connection.
7. Dark Spots on the Screen.
Move speakers,USB modem and other magnetic devices away from the monitor.
8. Incorrect Colors - red may become dark brown, blue becomes purple.
Check your video cables and connectors for bent or broken pins and wires. Sometimes there may be a problem with your display card, which can be retuned using a software available with monitor technicians.
9. Run Antivirus to scan corrupt software files.Virus cause distorted characters and images.
10. Set your monitor/display pixels to the software requirements. some softwares require higher pixels to run or to be displayed. some media players, web applications, video games applications and photo editors/view softwares have option to view photos on low or high quality

Unable to have 1280x768 full screen with DVI cable

Use the menu button on the monitor itself to adjust for the screen size in DVI mode.


On your SVGA adapter, go to your display properties (right click on desktop) click ADVANCED and change the refresh rate to fix the first problem mentioned.
