FIXED PIXEL DISPLAYS – SELECTING THE OPTIMAL RESOLUTION AND
REFRESH RATE
Display devices based on LCD, DLP, LCOS, and plasma display technology have a specific number
of display elements, or pixels. This is also referred to as the “native resolution” of the display device.
These devices are usually capable of showing higher or lower resolution signals, but can only do this
by scaling the image up or down to the native resolution. In order to avoid additional image scaling it
is important to know the native resolution of your display device.
Check your operation manual to determine the native resolution of your display device. The video
scaler output should be set to match this native resolution. The video scaler output refresh rate should
be set to 60 Hz with most LCD, plasma, D-ILA / LCOS and DLP displays. Higher refresh rates are
not recommended with these display technologies because they usually do not improve the image and
may actually cause compatibility problems.
