Macbook Pro mid 2011 screen glitching

That looks like an issue with the built-in Display Assembly.

Connect an external display to see if the same thing happens on the external. Enable mirroring to the external display to be certain. If it only occurs on the laptop's built-in display, then you know for sure the Display Assembly is bad.

I hate to break the news to you,KHL____, but it looks like a hardware problem to me. If you hold down the shift key while rebooting, you should be able to get into safe mode and see if the problem repeats. I’d also recommend doing a back up of your main hard drive as well which every Mac user should do regularly for peace of mind and safety. It is easy to set up and do, Requiring only an external hard drive with the same roof capacity as your MacBook Pro mid 2011, what is about 800 gigs. The graphics card in it is technically replaceable but it is a royal pain in the butt to do so. You might be better off looking for a newer MacBook Pro or a refurbished one somewhere.

Sorry to hear that. I think you’re right. Apart from trying to boot a disc recovery application from the built in dvd drive or the USB port, or trying Apple Recovery of some kind, hold down Apple (command)+R key on startup, or Internet Recovery ( option, apple+R held down on reboot) ya might be up the creek...... i guess you’ve tried the usual stuff-reset smc/pmu and zap pram first, yees,,right??? And you have already done a backup and backed up your stuff, yes right ??? Might be time 2 say goodbye to it.
