Hello,
I am having an issue with a Brightsign LS445 connected to a Samsung QM43B. I have it on input 1 and another source on input 2. When I switch inputs via Crestron control to the Brightsign, it will not output any video until rebooted. I put an analyzer on the end of the HDMI and it didn't see anything. Once the Brightsign reboots, it is completely fine until the display is turned off or the input is switched. Has anyone ever seen that?
