How do I change the frequency or refresh rate the
monitor uses? (Digital DV I Input)
Due to its digital design and the implementation of the new
digital standard interface, the LCD monitor supp orts fixed
frequency used in the DVI Standard up to 1280 x 1024. Unlike
traditional CRT monitors in which electro n beams are
co nstantly scanned acro ss the screen, there is no need to
change the refresh rate of the d igital input LCD monitor
because screen flicker is not a p ro blem fo r this typ e of
monitor. The LCD monitor also supports lower resolutions
(1024 x 768, 800 x 600, 640 x 480, etc.) by scaling these lower
resolution mo des up to the 1280 x 1024 resolution req uired
by the monitor.
The screen flashes during boot-up or resolution changes.
While bo oting up or changing resolution, the graphic card
re-initializes its video memo ry and this is so metimes
observed as screen flashes. The effect of this pheno menon
varies fro m card to card and it is not considerd a problem.
If you are unable to correct the problem using the
TROUBLESHOOTING section.
Please refer to the cover of this manual for any warranty
information or number to call about obtaining service on
your LCD Monitor.
