You can scale the wall up to huge sizes with enough units and each TV is rated for 24hour/7day operation. The video processor is built in to each TV so you can either send a signal to one TV and it will spread it across the wall or you can run each TV on it's own source and jump back and forth between video wall and individual sources. They are direct lit LED's so there's no light bleed or bloom on them either. If you make changes to one's video settings you can export it to a usb stick and import it to the other units instead of doing it manually/remote. The bezel is 1.75mm thick so when you place them together in a wall the total distance between actual displays is only 3.5mm.Įach set is factory calibrated so that they display is uniform across all units in a wall. These particular TV's are pretty cool though (protocol aside). Connect the 2 DB9 ends of the Serial to USB and Ex-link cables, plug the 3.5mm jack into the Samsung TV service port. There is actually a commented line in it that says *abandoned, protocol sucks, no response, no power on, must use IR* Connect the DB9 (RS-232) to USB to your PC (USB end) and install the driver. Later, after dealing with a Sharp LCD that had energy saver settings i learned that turning off energy saving would allow the The ON command to work. When i was testing the commands a couple years ago i wasnt able to get the TV to turn ON with RS-232, all the other commands worked perfectly. When I started digging for my rs232 JS file I finally found it. I have an RS-232 document for EX-Link also.

You could only power it off or issue other commands while it was powered on (volume, channel ect) and there was no feedback except an ACK or NOK response. When I gave up on Samsung TV's several years ago you could not power on a Samsung from the exlink/232 port. Not only that, I can actually query the TV's for their state!!! ZOMG!!! I don't know if this is limited to these pro televisions (its a 4 panel Samsung UD55EB video wall) but power on via rs232/exlink actually turns the TV's on.
