Q: MacBook Pro resolution problem (1080p) using El Capitan
Hi all,
I have a MacBook Pro Mid-2012 running OS X - El Capitan 10.11.6. In addition, I have a LG monitor 23 inches (model 23MP55). I'm using a Thunderbolt to HDMI cable to mirror my display, but I'm getting an issue. The monitor starts to get noisy when I put a 1080p resolution. However, it works fine with a low resolution like 720p.
I tested my MacBook using another operating system, and it just worked perfectly well on the highest resolution. Also, I tested my cable in another monitor, this time running OS X in my MacBook, and it worked fine. Moreover, I reseted all things that I could NVRAM, SMC, and I even reinstalled the OS X.
I think is probably a issue evolving the video card driver. Do you guys have any clue what might be? Here is a picture of my monitor with this problem.
