Timing Chart The ViewSonic G800 digital monitor can run at an extensive range of resolutions and refresh rates. Certain standard resolutions are factory preset. There are also 18 timings which are user definable. For example, if your video card is set up to run 1024 pixels x 768 lines at an 80 Hz refresh rate, once you have adjusted the screen size and position to your preferences, the monitor will save this information to memory. Every time you run this resolution at this refresh rate, the monitor will recall your adjustments. The following table lists the maximum refresh rates at which the ViewSonic G800 will operate at a number of standard resolutions. While the monitor is capable of this level of performance, not all video cards are capable of running at these high refresh rates. Please see your video card user's guide to ensure compatibility. Warning: Do not exceed the maximum refresh rate listed in the table below for your monitor. Doing so may result in permanent damage to the monitor. Some graphics cards support refresh rates higher than the monitor is capable of handling.

The resolution is the number of data pixels times the number of data lines that make up the screen. 2. The horizontal frequency is the speed that the electron beam travels across the screen, left to right. 3. The vertical frequency, or refresh rate, is the speed that the electron beam finishes all the rows in the screen and returns to the top. ViewSonic G800 Operation 11
