Hi all! I've just received new monitors at work. They are bigger and nicer than before. The computer is the same. Previously, I had no problem playing videos on any major streaming service. Now, I can only watch YouTube on any browser and Netflix on IE and Firefox (but not Chrome, and I do mean IE, not Edge). Any other streaming service (Amazon, Hulu and Showtime Anytime) does not work. Spotify's web player also has the same problem.
The issue is that as soon as I start to play a video, the screen will immediately go black and after a few seconds, both monitors (same model number) will indicate that they have lost signal from the computer. I can hear the sound playing in the background. If I alt+F4, the browser will close and the monitors will reconnect. I am running Windows 7.
Interestingly, if I restart my computer I can once again play a video in any browser, but only for a short time. After a while, the monitor will once again disconnect.
Any thoughts? My tech support is at a loss but have narrowed it down to probably being an issue with Flash.
