Yes, Target Display Mode came back with Monterey and nobody realized it.
Nice it works on Ventura, did not test it....
Ventura has a lot of problems especially on pre AVX2 hardware like our iMacs. OCLP does not support these iMacs, so do not wonder when finding a lot of bugs.
Console app provides logs, OCLP debug version provides logs, but currently we do not want bug reports of unsupported (by OLCP) Macs. Most of them we already know and it is a pain....to see another post ending with "any fix?".
Appreciate your help, but please no Ventura discussion here (it is about the graphics card) or on Discord (unsupported system), check this thread....
Bad things happening ..
Yesterday I was trying to do something with another SSD, but because I was tired, during assembly I attached the display on the iMac very badly. At the morning the display fell, the connectors were damaged.
After re-bending pins in connectors - Fortunately, everything works, except for one thing. GTX780M doesn't want to work anymore. When I turn it on, I have 3 LEDs (disconnected display) and the iMac has a chime loop. After plugging in the old GPU (HD6770M) everything is OK.
What could theoretically happen?
I tried to refit the GTX twice but no changes..

This is the exact reason why I stop assembling my iMacs on standing position.
Now I always place their back on the face of a low table with 360 degrees of open space around.
One small cardboard box to lift the LCD panel high enough so I can reach both my hands to inside the iMac.
My backlight high-voltage board seat is also damaged not inserted can also be used without much effect, my pads are ripped off. I tried to weld myself unsuccessfully.
The screen seat is also damaged I welded myself to replace a can be used normally.

Since I could not get the K2000m working at all with my third iMac i7, I decided to try a "bake" with the native card: preheating oven at 200C, leave it there for 8 minutes, switch off the oven and open lid and leave it there cooling down. Mounted the card the next day and guess what? It worked!
Do not know how long this will last so I am still curious how to proceed with the K2000M. As said, disconnecting Camera/BT did not have any effect, machine did not boot, only 2 leds.
Any ideas/suggestions?
Regards
Does Ventura work on iMac 27" mid 2011 with OCLP without any issues???104 / 5 000

No support with OCLP on Ventura as of now and please just check the docs or the OCLP docs about the support situation.
My method for updating firmware was by SSH/Ethernet and boot from USB but since the card prevents booting, I can not flash the bios as I have done with other cards.
I did the same with the card, there is no communication with the board and the diode was not lit, but I decided to try and it was work
after booting linux I had such a path:
27 root@grml /lib/live/mount/persistence/sdb1/flash # ./nvflash_linux --save ~/original.rom

First of all, a big THANK YOU to all the people who contributed to this thread. Having the possibility to revive these wonderful machines is truly awesome.
Now to the bad news: I read so many posts from this thread I can't give an estimate, but still... I can't get my iMac to POST with the new GPU
Situation: WX4150 on 11,3 iMac
Install the new card with copper plate, K5 pro paste for memory and MX-4 paste for the GPU. Detach the internal hard disks to boot from @xanderon's grml-based usb. After discovering that my ethernet module is fried, I use a usb keyboard to blindly setup a wifi connection. Finally, with an SSH connection I flash the
Now I know that I can't get the boot menu since I don't have OC installed, but I would expect to see the grml usb printing stuff. I have tried to flash other vBIOSes, specifically the ALT version from @internetzel's post and the WX4130 GOP and ALT (thinking that maybe they sold me a different model), but after each round of: blind wifi setup, flash, reboot + PRAM reset... I get the same black screen.
Did I do something wrong in the process? Can I try something to see if the problem is the card itself? I am starting to think it could be defective and not as new as advertised.
Here is the result of the first flash of the
P.S. since the close-up image is not so clear, the VRAM memory of the card has the following writing:

No, you need OC to switch on the backlight on boot to see at least something.First of all, a big THANK YOU to all the people who contributed to this thread. Having the possibility to revive these wonderful machines is truly awesome.

Check the first post for the known issues with these cards and High Sierra. Double trouble....
P.S.:
If you took these pictures before testing the card yourself I would guess it was not really new. You might see the difference in color or the gold MXM slot contacts. The first approx. one millimeter is darker than the rest of the contacts. A sign it has been plugged into a computer/slot before. New cards have equal colored contacts
