Mac Pro 2013 Pink Startup screen

Just a quick update...
I am still having this issue, I contacted Apple around 2 weeks ago and they booked me in to have my Mac Pro serviced by Stormfront over here in London UK.
I was called by the Apple technician who said that he was unable to reproduce the pink screen problem and the Mac Pro was starting up completely normally. He also said that he had run diagnostics on my Mac and everything passed okay.
I collected my Mac Pro today, took it home and started it up and found the pink startup screen still there.
I'm not sure what else to do now? Has anyone found a solution to this issue?

If your monitor has another connection port except HDMI, please try it.
Or try a different monitor, and different connection methods, just to check.
If the issue is always there, you have to insist for repairs...
[doublepost=1483776220][/doublepost]Some more options:
1.Also try to reset (again
) your PRAM/NVRAMBut do not press the (⌘), Option, P, and R keys only for once - one reboot.
Startup and hold them pressed for 3 reboots before you release them.
Try this again and again.
Apple's directions:
- Shut down your Mac.
- Find Command (⌘), Option, P, and R on your keyboard.
- Turn on your Mac.
- Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
- Hold these keys until the computer restarts and you hear the startup sound for a second time.
- Release the keys.
Good luck...

2. Also, is it possible to boot from an external HD, with 10.11 installed, and do some restarts with this HD selected as a startup disk, to see if there is a difference...

Thanks filmak!
My monitor only has 2 HDMI input ports, I have tried both ports with different HDMI cables connected to the Mac Pro. I've also tried connecting via HDMI to a 42" Panasonic TV, results are the same, pink startup screen.
I tried the PRAM reset method you advised but it didn't solve the problem.
I've also tried booting from an external USB3 SSD which had Yosemite on it and was upgraded to Sierra. In both cases the pink screen still remains.
I've sent an email to the repair company to say the issue is still there and I hope to hear from them soon. Other than that I don't know what else to do.
I am seeing the pink screen on start up after a fresh install of 10.12.2 (it was running 10.10.3 public beta before, but this was the first clean install on this machine since it was purchased 2 years ago) on a 1080p screen via displayport and HDMI.
On a 4 k monitor via displayport I get no image on screen until the login screen (thus I don't see the pink screen) . Previously I would get the regular boot screen.
I am pretty sure this is a software issue as it immediately started occurring after a clean install of 10.12.2. Running the diagnostics shows no errors. I have seen similar issues with some of the public betas. Resetting the pram and smc had no effect.
No other ill effects have been noticed.

Has anyone tried the macOS Sierra 10.12.3 update yet? Please let us know the outcome. I hope this one will solve the problem!
Not fixed by 10.2.3. I believe it is 10.2.2 sw bug, as it started right then. Funny if they have replaced a card for it.
Please help me understand this, if this is a macOS Sierra software issue then surely reverting to a previous OS X version e.g. Mavericks, Yosemite or El Capitan would get rid of this issue?
Could this be a firmware issue? I believe that firmware updates are now usually downloaded and installed automatically when updating through the Mac App Store.

I suspect the bug is either in EFI (hidden partition on boot volume -> unless you _really_ wipe the drive it is retained even if you format+reinstall), or firmware. Login screen is handled by EFI, so either firmware+EFI it _has_ to be, not actual OS partition.
Ok, I think I understand now. So is there any way to reset the EFI and Firmware to a factory state?
Thank you all for your detailed hints. In my case nothing changed (reset PRAM/SMC, different cables and monitors).
Its going to be worst. I've observed another issue with my nMP. Randomly my (BT) apple keyboard shows that it's turned off and turned on (keyboard indicator is blinking - keyboard connected then keyboard disconnected). After few seconds my mouse is frozen (Logitech MX Anywhere 2) and I'm not able to do anything. Computer/system works but there is no control on my system. After SMC/PRAM reset it worked fine - sometimes one or two days then finally problem is back ...
What is interesting, it never happened with Bootcamp (Windows 10) on the same machine.
I'm really upset and good for me I have apple care. Anyone noticed similar issue?
How to explain apple support that it happened randomly and this is difficult to reproduce?

Hi D9B!
Have you had any luck with the issues you're having?
Was AppleCare able to help you?
I recently had my computer assessed by another Apple Authorised Service Provider. The company is called Amsys and they were able to collect my Mac Pro from my home. They have assessed my computer and all of their diagnostics tests have passed however they were not able to reproduce the boot screen issue and therefore the problem remains.
The technician did mention that this is a known issue with macOS Sierra. The service I received was great even though my issue was not resolved. The whole process took 5 days including shipping the Mac Pro back to my home.

We did a diagnostic test (again) during my phone call with Apple Support. We didn't find anything. The guy has informed me that I should bring my Mac to Apple Authorized Point due to artifacts that are showing up during OS loading process (1 cm "artifact line" on the bottom screen is blinking). Referring to other issues I've, Technician said that it's very strange behavior. I need to plan my visit at Apple Authorized Service

Good News Peeps!
I was reading the following thread earlier and decided to install the 10.12.4 Public Beta 6 and the issue with the pink startup screen has been fixed! I'm super happy and I thought I would share it with you guys, I hope it fixes the problem for everyone.

Additional information...
DO NOT perform a PRAM reset! In many cases this causes the glitch in the startup screen.
Before updating to 10.12.4 public beta 6, I took a note of the BOOT ROM Version. It seems that this too was updated when installing the beta.
I also booted into internet recovery and the startup screen is back to the regular white (OS X Mavericks).
It seems that there are a heck of a lot of unusual graphics issues with macOS Sierra affecting many users with a wide range of Mac hardware, old and new. I think it's safe to say that this is a software issue.
I hope Apple can identify these issues and fix them in the coming updates. I would like to write to Apple to share my experience, anyone know of how I could go about doing this?

Well, if it's software, I'm not sure if it's specific to Sierra. I haven't updated to Sierra (still on El Cap) and have had the same issues described here and on other threads.
