I have an Optimum Samsung cable box and a PC hooked up to a 27 inch monitor, and I use the monitor's input select to change between them.
My problem seems to be that whenever I use the computer, the cable box thinks the monitor is off so it turns its own output off. Then, if I change inputs to the TV, the monitor doesn't see a signal so it switches back to the PC.
Thus, if I want to watch TV, I have to quickly cycle the cable box and change the input, hoping I get the timing right so they both see each other "on".
Is there any way I can lock the Samsgung's output on all the time like the PC is?
