Absolutely baffled on new Monitor display

[DrPopkorne]

I thought I'd post here as it isn't education related but home use.

 

I got a new HP OMEN 25 monitor last night for gaming and it was amazing, really nice clear display.. and used my old monitor as a second screen.. all excited for a long session of Destiny 2. After connecting everything together I made it my main display, set it to 144Hz 1920 x 1080 and played several hours with friends. I did install the HP driver directly from the website, but did not restart the PC afterward.

 

This morning when I turned on my PC only the old monitor displayed and the infamous 'No signal from the PC - Entering sleep mode' message appeared on my new monitor. I could not see any reference to the HP OMEN in device manager, no related drivers appeared to be there to perform a rollback, and on the Screen Resolution page there appeared to be a generic pnp monitor at a tiny resolution locked at 50Hz. Here's some of the things I tried:

• Restarting the PC again
  
• Reinstalling the driver again, however unlike the first time it didn't say 'detected omen 25' - instead 'detected generic pnp monitor'
  
• Reconnected all the wires, tried another Display Port cable and tested both were working on another device
  
• Used a HDMI cable which produces a display to test the monitor wasn't broken
  
• Performed a factory reset on the monitors UI panel
  
• Performed a system restore however it doesn't look like everything reverted back, the monitor software is still present
  
• Tried loading the HP monitor software but it closes with a not responding error
  
• Checked the NVIDIA Control Panel and there is a second display but it is showing as a DVI-D instead of Display Port
  

 

The monitor is plugged into my NVIDIA GeForce GTX 970, same as my HDMI monitor.

 

I am absolutely stumped at this, and gutted as I've gone through a chore to retrieve the parcel that was delivered to the wrong address only to get it as a lovely surprise last night and find out it looks amazing, only for it to go bust the next morning. Has anyone got any suggestions that might bring this to life?

Couple of things to try

 

On my ultra wide monitor my Display port isn't picked up unless I have a DVI cable plugged into the monitor too (doesn't need to be plugged in the other side) - wierd but works for me

 

Also searched and found this to maybe try > Windows 10 or GTX 970 does't detect 144hz Monitor HELP! (Also Display port issues..) - [solved] - Displays

That link has an interesting suggestion, it's not too far off my issue. I must admit one of the things I skipped was unplugging the monitor and PC power.

 

Sadly I'm at work now so I'll have to try later tonight. I feel quite dirty being an IT technician when I've failed to resolve a ticket for myself!

just an FYI and you probably do not have this issue but a display port cables limit is 3 meters (for max bandwidth) 1080p@144 maybe too much if you were using a 5 meter cable. (and maybe a cheap cable)

 

for testing you (an I'll assume a lot now) could enable multiple monitor mode in the bios and use the intel igp to test the monitor to help isolate the issue. (if you are intel and have dp on the mainboard)

[DrPopkorne]

It's about a 1.5m cable I believe. Sadly I'm using an MSI motherboard and couldn't locate a section in the BIOS for display of any kind.

 

I will maybe see about borrowing a different display port cable from work though as both ones I tried were the same make, could possibly be cheaply made.

Thanks for the suggestion suiko. This worked! Display Port seems to use a bit of power. We sometimes get display issues on our Dell PCs at the school that use a hdmi adapter, and the display port monitors stop working. Maybe I should have seen it. Could I maybe buy you a coffee for your assistance?

Hehe nice one! Glad it helped

 

Thanks for the coffee offer

 

Just help others on here when you get chance that will be enough for me
