Timing Chart
The Optiquest Q53 digital monitor can run at an extensive range of
resolutions and refresh rates. Certain standard resolutions are factory preset.
There are also 15 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 Optiquest
Q53 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 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.
