Hey there, I thought I would ask for some assistance from this forum as I am at my wits end with this problem. I am trying to run Netflix in fullscreen mode on my mid 2014 rmbp with gt 750 and intel iris dual graphics. It used to work just fine, however recently I have been getting some serious problems. Yesterday while watching in fullscreen mode,as soon as the menu tool bar timed out (faded away from the screen because I didn't use my mouse) the entire screen went black and there were rainbow coloured pixels flying around the screen. I tried a PRAM reset which resulted in fixing that problem, however now instead of going black when the tool bar fades away, my screens hue changes to a much darker blue colour, and whites get blown out super saturated and bright. Now, I have narrowed the culprit down as much as my limited computer knowledge can let me. When auto graphics switching is disabled, I have absolutely no issues at all with netflix in full screen. I even downloaded GFXCARDSTATUS, and using that little app I was able to manually select the gpu that i wanted to use. This is all great that my 750m runs fine, however I am wondering if the Intel Iris graphics card is failing? I ran startup diagnostics by holding the "D" key on startup, and it came back saying no issues. When using GFXCARDSTATUS to manually select the Intel Iris card, my issue returns. Some help would be greatly appreciated. Please note that this issue does not happen when using any other fullscreen apps, such as VLC player or Photoshop. Thanks and have a great day!!!
