The first thing that I would do is re-install the video card drivers. \n\n(I would not rely on Windows to be correct, since you can't make changes, so if necessary, I wold open the Pc and determine the exact make and model of the video card.  If you have an onboard video adapater, then I would go to the manufactors web site to identify) \n\nOnce I installed new video drivers, I would check to make sure that the video card has the ability to change and display different video modes. (640X480, etc.) You can change that via the Adapters settings in the Display window. \n\nProperties: To access the hardware properties for your video card or on-board video hardware, click the Properties button. This is the same properties window that can be accessed through Device Manager. \nList all Modes: This useful feature lists all the supported graphic resolutions and refresh rates that can be sent to the monitor by the video card or on-board video hardware. You can use the list of valid modes to find a mode that is compatible with the monitor you are using. Once a compatible mode is found, you can change the refresh rate from the monitor tab, and the display resolution from the settings tab of the basic display properties window.

What she need to do is to change back the resolution (the resolution was not changed automatically thow, and if her monitor does not support it, than it should return to normal unless she explecitly accepted that...). Restart the computer and press F8 and choose to restore the previous good configuration...

Right-Click once anywhere on the desktop (not on an icon) and click Properties.  Click the Settings tab and check your Screen Resolution.  Depending on the monitor, you'll probably want either 800X600 or 1024X780.

Try changing your display settings.\nStart, control panel, display, settings, then pick your screen resolution. Largest is 800 x 600. \nHope this helps, and I will look for more options.\nGary

Your monitor hardware does not support 1152 by 864 resolution selected by you. Turn off your PC and restart it in Safe mode, select the earlier resolution and then restart it in normal mode, your problem will be recfified.

You probably need to install/update your video card driver.  Go to your manufacturers website and download the most current driver for your model and OS.  Install it and see what happens.  It may update itself automatically or give you more resolutions to choose from.

Ok, well ... try the basics first, when you connect to the tv through the DVI cable you need to make sure you're computer installs and configures the right drivers. Go to the Control Panel and click "Appearance and Themes" and then click the "Diplay" icon. Then go to the "settings" tab. See what is listed under "Display:" It should be "Generic HD TV" or something to that effect.\n\nThe resolution cannot be higher than what you're tv will display 1080i = 1920 × 1080. \n\nAlso, try opening the Device Manager and see if you're display adapter has a little (!) mark. Try searching for updated drivers.
