I have been using a hdtv as a monitor for several years now, the only problem is since I've started mining and bought a sapphire 5830 and 5570, I can no longer switch my tv to another source and then back without locking up my computer. Has anyone seen this before? My google searches have been fruitless. I don't have to have the miner running for it to lock up. Same thing happens if I remote desktop! I assume its an hdcp issue of some sort but have no idea how to resolve it? Any ideas
You might be at the edge of your power usage? Switching a monitor might cause a slight power glitch that burps the gpu?
