how do you handle turning the TV's on and off. 4 TV's of the same manufacturer using one remote will turn them all on or off. However get the wrong angle and only two or three turn on. hit the power button again and the off one turns on and one of the on ones turn off. frustrating

I worked for a major proAV equipment maker for 16 years. This gear looks pretty good; price point, form factor, ease of use are all on point. But there's no talk of bezel compensation or any kind of degree of fine-tuning the wall. Be careful with this one. My professional opinion is 6/10.

Question for you. I'm having an issue that my images are sideways. I did the output rotation. However, all that does is move the image from left to right. Any suggestions?

Does this video controller pass CEC display on and off commands from the input to all of the displays?
