Question Generic Non-PnP monitor issue

[XelaOlf]

Recently I was having trouble with my ASUS VG278Q monitor, the back panel started acting up and I had to send it on maintenance. Since the repairs could take anywhere from 1-2 weeks, I borrowed an old Dell LCD monitor from 2005 and a DVI-VGA cable from a friend. A couple days ago my VG278Q monitor came back, but it isn't recognized by my PC and the device manager tells me it's a generic non-PnP monitor. I've tried hard resets and replacing my DVI cables, using DisplayPort and HDMI connections, doing clean installs for my GPU driver and installing the VG278q drivers manually - nothing is working. The resolution is stuck at 1024x764, and even when I try to forcibly set the resolution to 1920x1080 the screen stretches and looks awful. Anything I run causes the screen to black out and the display says that it's 'out of range'. I'm at the end of my rope here because ASUS has not helped me at all, and they want me to start another RMA that I have to pay more shipping fees for and wait another 1-2 weeks to use my monitor. Help would be greatly appreciated!

My GPU is a Nvidia Geforce GTX 1070 ti.

Try this

Win X > Device Manager > Monitors, open drop down, right click the PnP, select "update drivers."

When I did that the "generic PnP" switched to Dell with model number. I don't know if it will fix your issues. But there is some small non-zero chance it will.

You can also try looking on the net for OEM drivers, which I've never done for a monitor, but I guess there's always a first time.

You mentioned new gpu drivers, so I'm also going to mention a dumb thing I was doing that cost me an hour before I woke up and paid attention. I was working on my upstairs build (new gpu) which is Win 8.1. Since I now have Win 10 downstairs I pretty much automatically select Win 10 options these days. I couldn't get the #!%!@ drivers to install. Finally I realized I was on Win 8.1 not win 10. There were no drivers for Win 8.1. So I tried the Win 7 drivers and everything got better. So you need to review whether you might have been doing something obviously dumb (as I was). Unfortunately obviously dumb stuff is only obvious after you've figured it out.

Good luck,
Greg N

Thanks Greg, sadly the monitor is being registered as a generic non-PnP monitor. I actually did install the VG278q drivers that ASUS provides, but sadly they don't seem to be doing anything. If the issue isn't a faulty cable, which I've tried so many different cables, then I honestly don't know what it could be. Thanks again for your suggestions and I'll check to see if maybe there is some sort of obvious issue I overlooked.

Well you've tried new cables so you're ahead of most people. I don't understand the part in your original post where you said the monitor was "fixed." I can't imagine that OEMs have the resources to employ real techs to fix the defective monitors they sell. With PC stuff, it either works out of the box or it's never going to work IME.

ASUS monitors seem to have an issue where the back panel can overheat and burnout, that's what they fixed. While the ASUS techs were fixing that issue I borrowed the Dell monitor I mentioned. I just got my 'fixed' monitor back and now it's not being recognized by my PC, hopefully that clears up what I'm talking about.

Well I'm getting the impression that the fixed monitor is not really fixed. And who knows if you have the same monitor maybe they dropped some other monitor's innards into the frame.

I've got a Dell monitor U2312HM and it is the best monitor I've owned. It's 1080p I've decided not to upgrade to higher res or refresh because it's hard to get a piece of gear that just does what it is supposed to and does it for a long time. I've had this 5 years it must be getting over 20,000 hours.

With stuff like you're experiencing I eventually reach an aggro point where I'd rather spend more money on something else and move on. If the other monitor was working on your build get yourself a dell and have done. I have thrown what looks like "new" or "good" equipment out just to get it out of circulation and making people's lives miserable.

So say I'm having these issues and a guy lent me a dell and it works that begins to look pretty good compared to waiting for repairs installing drivers posting on fora and still, at the end of the day, not having a working monitor. So in that situation I'd say well maybe I should get me a Dell and eat the loss. That is essentially what happened on my RX 590 graphics card. It was the third one in just a few weeks. I felt that I was incompetent and didn't know how to install a graphics card properly. Eventually I gave up, bought a 1660 TI and it installed easy and works perfectly (at least for now). Turns out I know how to put in a graphics card after all. So I paid about $550 for a $300 graphics card because I have, into the bargain, a worthless brand new Sapphire Nitro RX 590.

It looks like you might be getting to that point with your ASUS monitor.

The reviews on Newegg are borderline for me. My ideal gear has a combined Newegg 5 and 4 rating of 90% or greater. 85%, which is what it is for this unit, means possible problems. It's a popular model however because of price and manufacturer rep I guess. There are a lot of references to problems with Displayport and backlighting.

I will add that for many products it's VERY DIFFICULT to find 90% + ratings including motherboards psus monitors and what have you. I was just looking at some Dells that do not meet my > 90% criteria. The 1660 TI I'm using DID meet that criteria and so far so good.
