G7 Monitor Not Detecting DisplayPort

[Gridsquare]

This past December, I purchased the Samsung Odyssey G70B - 32" 4k Monitor, model #LS32BG702ENXGO

When I turn my PC on, about 50% of the time, the monitor just goes to that "you have 60 seconds for DP to be detected or it turns off" screen. My second monitor, some old Dell 1440p, running on displayport, ZERO issues and detected 100% of the time. Now, if I unplug my G7 DP at the monitor and plug it back in, it seems to work. That, or I have to restart the PC and hope it detects it.

I have a very high end PC, 7950x, RTX4090, 64gb DDR5 ram, etc... all with the latest drives. I used this monitor on my secondary PC with  a 2080ti, same issue. 

I have updated every driver and firmware possible, nothing has fixed this. Any ideas?

Is that the 27" one (based on the model number)? I have the 42" one, model number is LS43CG700NEXXY. The menu for the device looks totally different to yours. 
I thought maybe you have a newer one and they changed the software. If that is so then they're not rolling it out for existing hardware as currently my software/firmware is uptodate.

Same. The menu on the 42" looks nothing like that.

The one in his pic is definitely a newer model since it HAS a different version of DP to begin with.

my one has display port 1.4 I think that’s why I can change it and after I changed it stopped working again until I unplugged the monitor

How I solved this problem is starting my PC up on a small monitor via HDMI while the Odyssey cable is not plugged into the PC, and then after I log in to windows on the small monitor and get to my home screen, I disconnect the HMDI cord and plug in the cord going to the Odyssey. Seems to work every time, just a useless extra step adde... and now I have 2 monitors instead of 1. Glad I spent $900+ on a monitor that needs another monitor (joke joke joke).

Samsung would fix this problem if they actually cared about their customers.

I was having the same issues. I switched off game mode and used HDMI port 2. Problem solved for me. Hope this helps 🙏

That's great that you figured out a way to relieve yourself of the migraine, but it doesn't help in the fact that we purchased a 144hz monitor and with using the HDMI cable, we're stuck at 60hz.  For me, if I up it to 120hz, by using NVidia CP, and switching to HD 3840x2160 (Native), I get the flashing on and off.

We all could have saved a boat load by just buying a small smart tv at this rate...but we paid for a gaming monitor and should receive nothing less than a product that works.

SMSNG needs to remove their thumb, if you catch my drift.

Let me share the fix that helps me regularly. The problem is, that for some reason Windows stop recognize the monitor and start treating it like a Generic PnP Monitor. Despite the driver being installed. This usually starts after the update within Windows or just going Suspend. In such case, disconnect the monitor and delete the unused PnP Device via cmd command:

pnputil /remove-device /disconnected /class Monitor

Of course you can first check what you are deleting by command:

pnputil /enum-devices /disconnected /class Monitor

You don't have to worry much about this, as it only deletes the information on the PnP installed hardware that is generated anew each time you actually connect to the device (that's why PnP, right). All those switching ports and similar above are I believe just another way to force Windows re-recognize the device.

What firmware are folks running on the Odyssey G7? I wonder if there's a correlation between that and other factors like OS, GPU drivers, etc..

I'll start:
Odyssey G7 43"
Firmware: 1622
Windows 11 24H2
EVGA 2080 FTW3 Ultra Game Ready 576.52
