SET TX PREDEFINE-EDID w

(default: 4K60-2.0)
Set the Pre-define EDID data
Where:
w is one of the 16 EDID options as given above.
GET TX PREDEFINE-EDID

When a specific EDID is required, it is recommended to use SY-PCTools (select SLIM70 PCTool
from list of tools menu) - load and save the EDID file and then select the MANUAL EDID option
by sending the SET TX PREDEFINED-EDID MANUAL

command to enable it.
To use the display EDID directly, set the switch on the transmitter to the Pass position.
4K Down-Scaling
Compatibility with 1080p display units is assured by down-scaling any 4K (24/25/30/50/60Hz)
signal to 1080p. All 1080p or less signals are simply passed through.
For 4K display requirements, 4K60 4:4:4 (or 4K50 4:4:4) input signals can be down-scaled to
4K50/60 4:2:0, ensuring the 10.2Gbps maximum output bandwidth is not exceeded (Max. 40m).
All lower bandwidth signals (< 10.2Gbps) such as 4K30 4:4:4, 1080p are just passed through.
There are three options available:

1080p: Down-Scale any 4K signal to 1080p

4K60-420: Convert 4K50/60 4:4:4 to 4K50/60 4:2:0 - (colour space conversion)

Auto: cat5e/6/6a cable and the display capabilities are analysed for optimal resolution /
colour space (4K 4:2:0 or 1080p) for 4K50/60 4:4:4 input.
Note: The frame rate is not altered – only the resolution or colour space is changed.
The following command selects the 4K handling mode:
