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). There is actually a commented line in it that says *abandoned, protocol sucks, no response, no power on, must use IR* When I started digging for my rs232 JS file I finally found it. 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.
