I'm pretty sure it's just the GPU going wonky or the PSU acting up, but I wanted a second opinion on this. Here's what's going on. I've got my DLP TV connected to my GPU with a straight HDMI cable, and another LCD tv connected with an HDMI cable going through a DVI adapter. The LCD TV has no issues, but the DLP TV will seem to lose the HDMI connection whenever I play a video. It happens most frequently with flash videos, but it can happen with an MKV too. Doesn't matter if the video is full screen or not. Now, my DLP TV is 73" and the LCD is only 22", and it doesn't matter how I switch the ports around, it's only the DLP TV that has this issue. I have another LCD TV that doesn't work too well, but I'm pretty sure that's an issue with the HDMI handshake or something. The computer detects it just fine, but the TV won't show anything. PSU is a 700w, GPU is a 570.
