3.3. Switching the EDID
1. Use a screwdriver to change the memory address on the front side of the
TX200/TX300.
After either one of the rotary switches has been rotated, the unit waits
approximately 2 seconds before the selected EDID becomes active. If the
EDID status is unchanged the EDID status LEDs do not blink, but stay
continuously lit.
2. The address 00 (zero zero) has a special function. If a monitor is connected
to MONITOR OUT, then its EDID is copied to the DVI INPUT connector. If
no monitor is connected to the output then the EDID transmitted to the DVI
INPUT connector is the EDID of the last connected monitor.
Info If an invalid EDID is selected, the TX200/TX300 does NOT give a HOT PLUG
signal to the source connected to DVI INPUT.
Info After every EDID change, TX200/TX300 toggles the HOT PLUG signal for approx.
1 second. Some graphic cards or DVD players do not sense the HOT PLUG signal,
and even if EDID has been changed, the set resolution is not affected. In this case
the source device must be restarted, or powered OFF and ON again.
3.4. Factory preset EDID list
Lightware factory pre-loaded EDIDs are specially provided to force graphic cards to
output only the exact pixel resolution and refresh rate.
Universal EDID (address 49) allows multiple resolutions including all common
VESA defined resolutions. In addition, it also features audio support. The use of
universal EDID is recommended for fast and easy system setup.
