I have recently purchased a brand new VISIO flat screen TV and am having issues getting the HDMI output to work consistently from my Dell laptop. I can now consistently get video from the laptop to appear on the TV just fine. The first time I tried running pandora through the TV it worked perfectly and I didn't have any issues. But now, one day later, whenever I try to run a video with sound, or even just have pandora go through the tv the TV screen goes black. If I continue running the video it will eventually go blue screen on the tv and say "Not Support!" This is very frustrating and I'm hoping someone can give me a fix to this situation where it seems that the TV is having a hard time handling the data coming to it from the laptop.
