OK. How do you plug in to the monitor? Is it through a VGA or DVI cable? Or do you also use the HDMI on your monitor? If you are using VGA or DVI, the issue may be with the HDMI. I say that because if the BSTV stream is copy protected, it may not see your graphics card as HDCP compatible and thus it would block that stream from running over the HDMI. That's a stretch but is a possibility. One thing I would try, though, is to turn off your PC, plug in ONLY the HDMI cable to your Big Screen, no other display hooked up at all, THEN turn it on and try out BSTV. I have seen it work that way before. Basically your PC needs to see the HDMI Display as the only display from the get go. As another possibility, if you don't have the latest driver for graphics card, try and download and install the latest driver and that may make a difference. Make sure to reboot after the install, even if it doesn't say you have to.
