Motherboard does not detect GPU when displayport monitor is turned on?

Hello,

 

I just purchased a new monitor and after getting it all setup and connected my PC began to beep 5 times when booting up.

Doing a quick google search on 5 beeps on my motherboard i found a couple of older form posts saying that its caused by the mobo not detecting the GPU.

But if i let the PC sit, it boots to windows and everything works flawlessly. Its just during POST that it seems to have this issue.

I also noticed that when booting i was no longer seeing the Asrock logo with the option to boot to bios. So the no GPU makes sense to me.

I have three monitors total. One connected DVI, one HDMI, and the new one connected display port. Before the new monitor i had a display port to DVI adapter in place of the new display port monitor.

The strange thing, is that if i turn off the display port monitor the PC boots with no problems, the POST boot screen with the asrock logo shows up on my monitor connected via HDMI with no issues.

 

I have tried two different display port cables thinking maybe the cheap cable i got off amazon was the problem. But that didn't change anything.

 

Any ideas why my PC wont detect my GPU when i have my new monitor connected?

 

Below is a screenshot of my PC from HW monitor to give you an idea of my specs as well as a link to the new monitor that i purchased.

This is gonna sound like stating the obvious, I assume you have made sure that the monitor is on the correct input yes?

Technology is like a good friend that does its best to piss you off at every turn. yet we love them anyway.

A fair question. Yes, i tried with the monitor both on auto input and manually setting it to display port.

Have you been able to get an output to the monitor over any of the other connectors? Or HDMI?

The monitor works on display port once the PC boots to windows. It's just during POST that it doesn't.  

 

I have not tried using HDMI to the new monitor as I want to use display port for the higher resolution.

I have tried both of the display ports on the GPU. No difference.

Maybe the monitor simply takes a long time to wake up? One of my monitors starts showing an image during the boot sequence, the other one only wakes up at the login screen. But if I boot into BIOS then it will also show an image there once enough time has passed.

Just DP being DP. It has never worked properly for me on modern BIOS's on 3 different brands and models of displays. That's why one of my secondaries is always on HDMI so that shows the BIOS.

I tried to boot to bios and let it sit for a good 5 minutes and it never came up.  Booting to windows is much less then that and comes right up.  So don't think it's an issue with it waking up.

Thanks for the replies everyone.  Sounds like there isn't really a fix other then swapping from Display Port. So weird though that if I have both my DP and HDMI monitors on it won't work. If I turn off my DP it works on the HDMI monitor no problems.

I just did a bios update on the board about a month ago so I doubt there is a new one just yet but I'll double check tonight once I'm home.
