So what could it be? Is it software or hardware based?Īll the problems you guys mentioned above are related to a faulty graphic card. The issues mentioned above started when I was using the monitor, but I had the same issues when I disconnected any external devices or peripherals later on. It's a fairly heavy screen running at full resolution of 2560x1440 but that's completely supported by Apple. I recently started using an external monitor directly through the mDP. I used the Apple Hardware Test to identify what might be the problem but with the normal as the advanced test results say there no issue with the hardware. Since then I tried to reboot but every time it cuts of the boot and the screen goes completely blank.

I'm using a MacBook Pro 15' late 2011 running 10.10.5 and in all of a sudden my screen is acting weird. If you think you may have a medical emergency, call your physician or 911 immediately.I think my graphics card is failing but I'm not 100% sure.
