2010 mac pro 5.1 display stopped working & will not come back on

2010 Desktop Mac Pro 5.1 was working great for years. Still using Snow Leopard 10.6.8

for making use of music software. Machine started acting odd by screen sometimes not coming on and having to restart. It worsened until one day it just would no longer come on at all. I purchased a new Radeon HD 5770 because everything on the net said the card was most likely the problem. It is not the card. After replacing it, the machine chimes it is on, but screen remains black. I use the mini port with an adapter to HDMI. Checked the cable, it is good. Tried a different cable, same thing. Monitor works fine as TV screen. What do I look for next? Everyone has phones now. All the Mac fix stores are gone. I want to stay with the desktop. My screen is 32” big. I like it like that so I can see the music I write. Also the software demands 32G of RAM. A little pocket phone can not do the job. Please Help.

You are correct, the first thing that goes on these is the video card. To test you need a KNOWN GOOD replacement card. So first find out if indeed that new card is good. The second thing that fails is the power supply. It can be a partial failure. The symptoms are usually that the machine reboots on its own. Over time this increases in frequency until it is doing it four or five times a day.

thank you mr mayer. changing the card to a different slot did not remedy the display problem. I have tried changing the HDMI micro adapter to the other port just to eliminate that possibility as well. Power cord is OK. HDMI cable is OK. New 2032 battery installed. I have tried changing the connector cable for the Radeon 5770 from PCIE Aux A to PCIE Aux B just because I thought it might refer to which port I plugged the new card into. No luck there either.

If the tiny white button next to the battery is a PRAM reset button, I have depressed it as well. Still, the machine chimes on every time but the external monitor [which works fine] stays black. I always recheck the "source" option on the remote just in case as well. I will be glad to pay someone to identify or even better- fix it as working on this HP PC makes me nuts. I have been a Mac person since my 1st PC back in 1990. All my pals in entertainment said it was an absolute necessity. I now agree.

What was the source on the card? If you want me to, I can check both cards on my Mac Pros.

The physical slot the video card is in might be faulty. Try moving the video card into a different slot and see if that helps.

If this doesn’t help maybe change which port the cable is plugged into on the monitor?

Other than this I cannot tell what is wrong I am sorry.

I am facing a similar problem. My Monitor is not displaying anything , but i can hear the MAC is booting and working. After long researches, i am now going for a new card thats Metal Compatible. the new Mojave and catalina versions need metal compatible graphic cards.

Why dont you also try this.

According to Apple, the following graphics cards are known to be Metal-capable and compatible with macOS Mojave on the mid-2010 and mid-2012 Mac Pro models:

  • MSI Gaming Radeon RX 560 128-bit 4GB GDDR5
  • SAPPHIRE Radeon PULSE RX 580 8GB GDDR5
  • SAPPHIRE Radeon HD 7950 Mac Edition
  • NVIDIA Quadro K5000 for Mac
  • NVIDIA GeForce GTX 680 Mac Edition

Apple also lists other AMD graphics cards that "might" be compatible with macOS Mojave:

  • AMD Radeon RX 560
  • AMD Radeon RX 570
  • AMD Radeon RX 580
  • AMD Radeon Pro WX 7100
  • AMD Radeon RX Vega 56
  • AMD Radeon RX Vega 64
  • AMD Radeon Pro WX 9100
  • AMD Radeon Frontier Edition

You can check to see if your graphics card is compatible by holding down option while selecting Apple logo to access System Information. Under Graphics/Displays, if "Supported" is listed next to the Metal entry, the graphics card will work with macOS Mojave.
