Timing Chart - ViewSonic E655 User Manual

Timing Chart

The ViewSonic E655 digital monitor can run at an extensive range of
resolutions and refresh rates. Certain standard resolutions are factory preset.
There are also 16 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
E655 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.
Video Timing
The video timing mode is made up of three elements:
1. The resolution, which is the number of data pixels times the number of
data lines that make up the screen.
2. The horizontal frequency, which is the speed that the electron beam travels
across the screen, left to right.
3. The vertical frequency, or refresh rate, which is the speed that the electron
beam finishes all the rows in the screen and returns to the top.
