Anyone have any luck getting the remote to work? I am on my second unit and neither remote seems to work. Tech support has been no help.

BEST ANSWER: From the pdf manual available on the webpage for item# 43979 there are 2 possibilities. 1. The box must have the IR Receiver dongle plugged into the 3.5mm IR receptacle. 2. The manual does not specify the proper battery size to use for the remote. (e.g.: 2016, 2032, etc.)

Same here. Also on my second unit and neither remote has worked.... Obvious quality issues. At this point I've given up with the remote and will use the on-unit buttons. Agreed, tech support was not helpful other to recommend another coin cell (which I tried...).

No luck here. Monoprice has been removing all of the reviews as well since multiple people have complained about the remote not working.

This device claims "includes advanced EDID® management". How is this handled? I do not see an ethernet or USB port for communicating with the device. Are there RS-232 commands for EDID management? Or is it less "advanced management" and more "caches EDID of attached display".? Also, where can I find the RS-232 command set document?

BEST ANSWER: EDID modes are switch selectable as listed on pgs 12-13 in pdf available on webpage for item# 43878. CEC RS-232 commands are listed on pgs 12-18.

Affordable switch with EDID
Works great. EDID function is awesome as your windows will not get rearranged when switching between inputs. They easily stack on one another with included brackets.

Remote does not work
Remote did not work on first unit. Monoprice sent a new unit. Remote does not work on the second unit either. Piece of junk.
