I just received and set up my Slingbox PRO-HD today and after doing so I noticed there is a green tint to all the colors that should normally be black or red. I thought the issue might have been with my laptop but I ran into the same issue when I installed the slingplayer app on my tablet as well.
When I have the tv that the slingbox is connected to on there isn't any color distortion at all (this is hooked up to my cable box via HDMI and not component).
I tried swapping out the component cables and that did not seem to work.
Any other suggestions? As other posters have noted there isn't anywhere to adjust the display settings through the app.
