I submitted the post above. Has anyone not seen this? I still don't have a solution. But the fact that nobody has seen it means its something simple, being overlooked. To me its a bit suspicious that it aligns with the current position on the video position progress bar below it. Sure, its centre screen, but did some sort of display indicator get toggled that I can't find a way to turn off?
it s not a windows 10 issue
i have the "middle vertical red line" also on windows 7 (updated my initial reply)
i have also tried the latest stable and beta AMD gpu (R9 390) drivers, and the red line is still there
i have uninstalled and reinstalled the ie / chrome / firefox plugin, and the red line is still there

i found a an old .avi video in my pc, and i played it using Windows Media Player... that resulted in the same mid red line
(so it got me thinking that the issue is not related only to slingplayer)
so i googled "red line windows media player" and i actually found several results... mainly confirming that this may be caused by a setting from the amd graphics card : DEMO MODE
i had no idea that was turned on by default... disabling the function worked for me
slingmedia-admin you may close this as being resolved
I have vertical red line, perhaps 10 pix wide, exact centre, on whatever content I am displaying from my slingbox. It only happens on a single Windows 10 workstation, not on any other Windows 10 laptop or other device.
The ads do not have the red line (blahhh) but the streamed program does. This appeared about a month ago and I'm not sure what changes were made to cause it. Perhaps a Windows update, but every other Windows machine is fine.
Its not full screen, just in the program display window of SlingPlayer (when the video display isn't full screen it is confined to the SlingPlayer video display frame).
Have uninstalled and reinstalled.
Have played with display driver settings to see if one of them is causing it, nothing yet. Display adapter is Radeon R9200. LG monitor using HDMI.
Have searched the web, have searched the Radon site.
