External Monitor via Airplay

[testtobi]

Hi,
I very often use an external monitor and the gpu panic appears not very often. With the fix and no external monitor they don't appear.
But I prefer working with an external monitor, so I thought about using airplay and an apple tv to connect the monitor "wireless" to my macbook.
Do you think this will gonna work with no gpu panics?
I don't have an apple TV device now, so I can't test it.

Hello-

I can only give you my experience with that situation. About 6 weeks ago I successfully installed the GPU patch and my MacBook Pro behaved fine after that (with no external monitor). A week ago I had an occasion where I needed to use an external monitor. Very shortly after connecting to the external monitor the GPU panic returned. It was so severe I could not get my MacBook to run for more than 10 seconds (after rebooting) before it would crash, due to a GPU panic. Since then I have tried with 3 different external monitors and got the same result each time.

I have no idea why using an external monitor would make a difference, but clearly it makes a big difference. Apparently more work needs to be done to have the patch include a use case of an external monitor. This was a big blow to my plans for using my MacBook..

My understanding is that the patch works by limiting the amount of GPU that the OS is able to take advantage of. ie it throttles it to level 2, whereas level 3 is when the GPU panics.

Unfortunately, when you plug in a monitor it forces the GPU to level 3 regardless of what the kext tells it to use. This is hardware level switching.

Ultimately, this is a hardware issue (from Apple!) and we're lucky that Julian has made us a patch that works at all.

Hi! Just to report my experience: I now use my MBP mid.2010 at home, but up to the last December I've used it at work connected to the 27" Dell display and Julian's patch worked…

I can confirm that the patch somehow worked for me with an external monitor as well. Like a week or so. Then the macbook crashed (for some other reason I guess because there was no kernel panic screen afterwards). Now however it crashes very often works, although I applied the patch again.

For now I disconnected the external screen and forced the GPU to integrated only.

Hello, thank you for this patch, I also have a MBPro 2010 - 15 "- i7, the patch works but not with an external monitor.As soon as I plug it and I open FFox for example, the mac crash and reboot. It's come from an hardware condensator issue : [https://www.youtube.com/watch?v=DzcgT_fiVTA]

Hello @kameleon1er. Yes, what you are saying is exactly what is said in the FAQ :

As said in Disclaimer section of the project, the fix will not work when using external screen. In this particular mode GPU internal firmware has more privilege than the kernel extension file : it's kinda overriding the fix. Hardware fix is necessary if you want to use external screen. You can also check this video if you want to fix the board : https://www.youtube.com/watch?v=DzcgT_fiVTA

Hi all,
I face this same issue during usage of external monitor via hdmi>display port adapter.
Setup without the external monitor is work like a charm.
Fun fact is that the cause of instant crashing is when you start move your bookmarks on Edge browser.

The fix does not work with external screen as said in the disclaimer section of the readme file here : https://github.com/julian-poidevin/MBPMid2010_GPUFix#disclaimer
