Re: Non-Scaling Splitter (RSP1:2 & SP1:8)
Description of terms used in this paper:
EDID = E xtended D isplay I dentification D ata. This is information that the display sends when
the communication is set up between the source and the display. The display send this
information and the source decides what signal to send.
Scaling = The ability to change a signal to another format. The most common scaling is to
scale down from 4K/UHD to 1080p.
The way a non-scaling splitter works is that is copies the EDID of output one. Essentially the
source sees only this signal request (EDID). For an example if you had a 4K/UHD display in
output one of an RSP1:2, the source would see the EDID of the 4K display only and send a
signal that is appropriate for the 4K/UHD display in ouptupt 1. If the display in output 2 is not
capable of displaying this signal, you will not have an image on this display. The solution is to
swap the outputs so that the “lessor” display is in output one and the source will then send a
signal that is compatible with that display. For an example the display that was in output 2 is
1080p, then the source will now output a 1080p signal. The 4K/UHD display that was moved to
output 2 will now get a 1080p signal.
Although rare, it is possible that neither request is compatible with both of the displays. In this
case you will need to override the EDID of the displays by using the switch on the splitter. The
switch when moved from TV to STD will now send a 1080p stereo EDID request to the source.
It is nearly a 100% guarantee that both displays will be able to process a 1080p signal. The
exceptions are very old displays that were created before 1080p and they may not be able to
process this signal. A more complex solution should be used, such as a scaling device on that
output.
