I understand you are having difficulties watching your Slingbox via Newwatch.Slingbox.com on the second monitor for your PC. Unfortunately, we do not technically support using any of the SlingPlayers on a second monitor. The good news is that there are other options for streaming other than Newwatch.Slingbox.com, so you might be in luck!
The other SlingPlayer options you could try on your PC are listed and explained in the article below:
Hope this helps!

It's been a year and a half.. Can this be revisited? It's absolutely ridiculous to say that we can use sling to watch TV, but NOT on a second monitor... Afterall, the reason most people would use this is to watch TV while working on their PC - If watching TV was going to be the primary activity, I'd probably just sit in front of a TV?!
Can you point me to where in the instructions or other documentation it points out that the sling ONLY works on the primary monitor?
