Question Monitor not recognized by Windows, driver won't install, can't get 144Hz ?

[patroclusx]

OS: Windows 10 (64-bit)
CPU: i7-7700k 4.20GHz
GPU: GTX 1080
RAM: 32GB (speed unknown)
Monitor: AOC G2460PF 144Hz

I ran into this issue first when I attempted to use the DisplayPort, and it wouldn't work. We'd just get a "no signal" message, if anything at all, but it'd usually just display a black screen and then automatically switch back to HDMI after some time.

A little research told us this may have to do with the drivers. Instead of the monitor driver showing up in Device Manager as its model name (AOC G2460PF) like it does in Settings, it's under General PnP Monitor. I attempted to update the driver to the manufacturer drivers several times, but each time, Windows determined that the best driver was already installed (even if I manually entered the exact location of the manufacturer driver).

I even uninstalled the General PnP Monitor entirely, to no avail. I also tried to install the INF file within the drivers folders (a thread here also suggested that, with positive results for the original poster), but that didn't work either.

I am on Windows 10 (64-bit) and have a GTX 1080 (latest version, 536.99). I double-checked everywhere to make sure that the 1080 can, in fact, run 144Hz. It can; I'm not going insane. But for the life of me, I can't figure out why I'm stuck at 60Hz or why I can't get rid of the General PnP Monitor driver or why Windows thinks the best driver is already installed.

I've been dealing with this issue for almost a year now, as it's never been a priority, but I'm done with keeping it on the back burner. Please, please help. I've experienced the beauty of 144Hz in the past, and I'd really like to get it working on my current set-up. Thank you!!

Update your post to include full system hardware specs.

Regarding:

"I ran into this issue first when I attempted to use the DisplayPort, and it wouldn't work. We'd just get a "no signal" message, if anything at all, but it'd usually just display a black screen and then automatically switch back to HDMI after some time."

And HDMI worked - correct? Are there both DP and HDMI cables connected at the same time?

Are you able to test video cables and the monitor on any other known working systems?

The objective being to narrow down to a potential culprit be that culprit the host computer, its' GPU, or the video cable(s)?

Take a look in Reliability History/Monitor and Event Viewer at the next sucessful boot and working monitor.

Either tool may have captured some error codes, warnings, or even informational events related to the DP failures.

Updated! The HDMI cable does work, yes. Currently, both are plugged in, but they're not usually.

The HDMI cable I am using worked on another 144Hz monitor (on a different PC; i5-7600k & 1060) and was getting 144fps. The GPU of that PC does not have DisplayPort capability as far as I'm aware and was achieving 144Hz on this AOC monitor as well, just with the HDMI cable. I'm not able to test this monitor or the cables I'm using on another PC right now, though, unfortunately.

I went into the Reliability History, and nothing stuck out to me that might be related to this issue. You might be a better judge, though, if you want to look at the screenshot here. As far as the Event Viewer... I'll be honest; I've got no clue how to navigate that or what to look for.

Thanks for replying so quickly, though! I appreciate it a lot. Sorry I'm personally not too much help.

G2460PF only supports 60 Hz on HDMI by default. You can use a custom resolution to get 120 Hz. But 144 Hz will not be achievable with HDMI on that monitor. As to why DisplayPort isn't working, I'm not sure.

Not sure that I understand correctly but I would not expect to see a GPU having its DP and HDMI ports connected at the same time to the corresponding ports on a monitor.

Switching video cables even if only one is left connected may be problematic especially with regards to @Glenwing 's post. When "confused" the system just rolls back to some simple default configuration.

As for Reliability History:

There is some problem with Apple Music - reinstall if needed. Uninstall if not needed.

Likewise for Razor Chroma

Not sure about the failed update warnings with respect to "YourPh" (Your phone?). Look at the details.

When I first got the DisplayPort cable, I unplugged the HDMI cord entirely and plugged in the DP cable. They're usually not both plugged in. They were yesterday because I was just quickly trying to see if I could get it to work again, like maybe all my previous attempts were flukes lol

Apple Music is an experimental app, so I'm not super surprised. I'll go ahead and reinstall both.

This is the message under technical details for the topmost failed update warning: "Installation Failure: Windows failed to install the following update with error 0x80073D02: 9NMPJ99VJBWV-Microsoft.YourPhone."

How would I go about getting 120Hz (with an HDMI)? That'd still be an improvement for sure, but when I try to change the refresh rate, I only have options up to 60Hz.

My partner said he had 144Hz when this was primary monitor, and his PC (the i5-7600k with a 1060) does not have a DisplayPort... but he also doesn't have the greatest memory (bless his heart) and could be mistaken with his current monitor.

I figure that the General PnP Driver has to be the root of this, since the DisplayPort cable is brand new... but it could also be the ports on either the monitor or PC... but I wouldn't know the first thing to physically look for.

My suggestion is to uninstall Apple Music and whatever is being represented by "Microsoft.YourPhone".

Is Phone Link installed? May or may not have been knowingly installed.

Just go without any Apple related software, features, and functions for a bit and focus on the HDMI/DP monitor issues per @Glenwing 's post and suggestions.

Change only one thing at a time and allow time between changes. At least a restart or two.

Objective being able to avoid some loop: Fix A to break B. Fix B to break C. Fix C to break D. Fix D to break A again.
