Mirroring will work for a short 25 second time frame and then time out back to sleep.

Doing quick searches, I found this is a common issue with High Sierra and mirroring to external monitors.

Sierra Cannot Overscan For External Monitor Acer Upgrade My OS

Unfortunately I cannot upgrade my OS any longer and dont really want to upgrade my Mac as it has been beautiful since I have upgraded to a SSD.

Anyone know if they finally got a work around for this issue Thanks in advance.

Are you operating your MacBook Pro Mid 2012 in clamshell mode If you are, the external monitor should mirror what the MBP has on the screen.

What I did was keep the lid closed on the MacBook and it would mirror perfectly.

If you open the lid on your MBP, it will extend the display, not mirror.

Or, maybe Im not understanding what it is youre trying to do.

I am attempting to use it in clamshell mode or with the MBP closed, having it display to my screen in a mirror mode.

Each of which have issue keeping the mirror mode on for more than 25 seconds or so before booting back to sleep mode.

When looking at the drivers, it is a known issue(according to HPSamsungAcer) that mirror mode bugs out when running High Sierra with an external monitor.

I have also read that my MBP will not accept 4k5k monitors, so I avoided trying those.

I was hoping since the last update about the issue was a couple years ago that there was some sort of work around but Im not finding any luck.

I looked up the specs for your machine and it still shows that its supported by Apple which is good.

I still cant find any reference to the glitch with High Sierra, however, is there any reason why you dont upgrade to Mojave With Mojave you can continue to use your 32 bit apps if you have any, and Mojave will format your SSD to APFS which will give you better speed and efficiency.

Your MBP can actually go all the way to Catalina but I dont advise doing that as it will kill off any 32 bit apps and drivers that youre using.

By that I mean which type of cable are you using Im assuming mini displayport.

When downloading the driver, there are some install notes, one issue being 10152.

Its a hard thing to find, but reaching out to HP and Samsung techs said the same.

Unless there is another way for me to upgrade to Mojave, but my software update tells me I am at my wall so to speak.

I am using a USB 3.0 data hub with a HDMI connector into my monitor.
