target display mode

Has anyone used TargetDisplayMode on his 2009-2011 27" iMac along with a 16" M1-3 MBPro? I’m just wondering if there are any issues created between the two resolutions that each Mac has. Do you see the MBPros display well on the 2K iMac?

I updated a 2012 MBP from Sierra to High Sierra a few weeks ago. As an external monitor I always use a 2011 iMac in Target Display Mode (Thunderbolt). The iMac runs Sierra. Weird thing is, ever since the MBP HS update, the iMac seems like it's been running extra hot and the fans are definitely...

Hey everyone, need some advice on some things and I figured this was the place. I have a Mac Pro 2010 5,1 that I have had for a few years now. Purchased a MSI AMD Radeon R9 390X series to bump up the graphics. I also have a Late-2009 27" iMac sitting around that I was hoping to use in Target...

Hello everyone, I recently bought one of the latest MacBook Pro 16" with M1 Pro processor, to replace my "old" 2019 MacBook Pro 16" with touchbar. I use my old 2021 27"iMac as an external monitor (iMac plugged with thunderbolt cable + thunderbolt/usb-c converter plugged into the MacBook Pro)...

Hi people! I was just google'ing for a way to turn the new 24" iMac (and future Apple Silicon ones) to an external display for a MacBook or PC. While doing so I came across this article: https://support.apple.com/en-us/HT204592 If i remember correctly, this post had red text at the top that...

Longtime lurker, first time poster. I'm just so chuffed that this worked I wanted to share it with y'all. I made the mistake of buying an M1 iMac without researching whether it would support Target Display Mode and of course it does not. I spent an hour on the phone with three different Apple...

I have a late 2012 iMac, model A1419, with a dead hard drive. Apparently, this 2012 model can be used as a Target Display in certain situations, but probably not mine! My working iMac is a 2020 iMac, model A2115. It seems that I could spend quite a bit of money just to find out that my 2020 +...

Hi All, A bit of help, please. I have a fairly good iMac pushing two target displays (two 2012 iMacs). When the displays are connected (USB-C to thunderbolt) they work fine -- so long as I am typing or working with the computer. However, some time after I leave the computer, the driving...

Hello, I would like to upgrade an iMac 2011 27inch to a xeon processor (e3-1280). However, the iMac also serves as good monitor for a mac pro. From what I gathered online, xeon will work but it would loose sleep function. Does target display mode put the imac in sleep function? if so, would it...

Hi Friends, I have 2017 MacBook Air. I'm using a 2010 iMac 27" in Target Display Mode as an extra monitor. I can't find this answer anywhere else online but I'm wondering if running the extra monitor in Target Display Mode uses extra CPU power from the MacBook. I'm sometimes struggling to...

I found many posts about this online and in this forum, but not for my configuration, which seems to matter. I want to use a mid-2011 Mac as a 2nd display for my mid-2017 Mac. • Main Mac: iMac, Mid-2017, Core i5, 27-inch, 3.8, Mohave 10.14.4, Thunderbolt 3 (USB-C) • 2nd Mac: Mac, Mid-2011, Core...

Hi, I'm trying to connect a Ryzen PC to my iMac 27" 2011 with a flashed K1100M running High Sierra, ( OpenCore 0.6.4 27" Nvidia config.plist ) but Target Display Mode doesn't work for some reason. I've tried it with a 2018 15" MacBook Pro using a 2m Thunderbolt 2 cable and a Thunderbolt 2 female...

As I understand it the M1 macs do not support target display mode. I have a 2011 27” iMac which I would like to replace with a new M1 Mac mini. However reading these forums it appears my iMac will not function as a display for the mini in target display mode (through thunderbolt). It occurred...

Since the first 27-inch iMac with Retina 5K display was released in 2014, Apple discontinued Target Display Mode for those models going forward. This was due to various technical limitations that were never overcome -- until today (potentially), with the release of the updated iMac 5K with the...

I have recently purchased a brand new MacBook Pro, and was hoping to use my mid-2011 iMac as a display, rather than cowering over the small screen on the MacBook Pro itself as I work from home a lot. This article on Apple's own site suggests it should be possible...

Everyone needs to go to www.apple.com/feedback and tell them to add target display mode back to their iMacs. This feature was available from 2009-to early 2014 iMac models. Apple won't know unless everyone lets them know that was an awesome feature that needs to be added. I am stuck with a 2010...

I'm having a weird issue with my 2017 MacBook Pro TB on Mojave with no sound playing from external monitor. I use my mid-2011 iMac as an external monitor with the MBP. When I have the MBP hooked up to my iMac with the thunderbolt port, sound plays through the iMac normally. Then a few minutes...

Just received the new 2018 13" MBP with the intention to use my 2012 iMac in target display mode. It worked perfectly on my 2016 MBP - but when I connect the new 2018 MBP, the iMac screen spazzes out and flickers then goes black...it seems to be a semi wide spread issue as seen in the Apple...

UPDATE: On July 28, my iMac died. We had 7 great years together, but the GPU gave out and I've moved on to a PC, rendering this thread moot. I have a 27" 2011 iMac that I want to use as a monitor for a gaming PC I plan on building. I understand this will only work if I have a special device...
