MG279Q

Most probably because if it's under a certain time frame since purchase, it doesn't matter whether they have technical understanding or not. They'll have to take it back, if you have buyer's remorse.

Ps. Or at least it was so with the old DSR (distance selling regulations). There was apparently new additions to the rules recently (like last year or so), so not 100% sure how it's nowadays. You might have to pay for the return fees.

Ps2. Neither the dead pixels nor the IPS glow would be categorized as faults, most probably. They would have to be GLARINGLY obvious and distracting in day-to-day usage, otherwise they'll just ignore them. Also, if you go via the manufacturer themselves, they might just send you a new one, which in turn might be a refurbished unit.
 
I'll be returning it. And I'll be wanting a replacement - I'll give the MG279Q one more go!
It was thinking about the sent replacement that made me think Asus might be better. Reseller might just blithely go and grab the next box from the warehouse whereas Asus - as they're no doubt familiar with this problem - might be more likely to send me a better one?
Wishful thinking I know.
 
Well, not sure how Asus handles things, but at some point there were some horror stories how Dell kept exchanging the returned monitors for refurbished units with increasingly worse flaws. The "next box from the warehouse" might be the better option, assuming the retailer doesn't stock refurbished ones, or re-send returned units without first sending them to the factory for refurbishing.

Then again, if there are no returns at that moment, they'll naturally have to send a new one.
 
I would go to the seller first, they will be faster. You might be waiting a month or more for Asus to return a monitor to you.
 
I'm a MG279Q owner and I see some glow/bleed/light from the bottom right corner but not the top right corner as in your photo - but it did go away when I moved my head.

If your new monitor looks the same then it could just be that these suffer from it.
Also in the bottom right corner is where the 'light from the power on/off is which is also a pure white light as well so possibly could be linked? (and it's a fair sized white light)
 
I know I have two concurrent threads going about this monitor, but I'll put this comment in this thread as the thread title is suitably general.

It's back to the point I mentioned earlier.
Why can I not get a higher refresh rate than 120hz?
I have the latest NVidia diver. Are there any specific monitor drivers I should install? I can't find any?
Is it something to do with the fact that if I right click and go to Change Resolution, the monitor there is listed correctly as the MG279Q, but if I open Monitor in Device Manager it's listed as Generic PnP Monitor.
I've tried changing the refresh rate in both the Change Resolution>Advanced Settings>Monitor box, and also the NVidia Control Panel. There is no option higher than 120hz.
I think it must be something to with a driver that speaks to the monitor, because when I first turn the monitor on - before it has properly 'shaken hands' with the machine - the OSD shows that the monitor has a 144hz refresh rate. this soon switches down to 120hz as Windows 7 loads.
Any ideas??
 
I don't know if it's just a coincidence, but at Tom's Hardware forum, there's someone else with pretty much the same problems with 144Hz and GTX770.
http://www.tomshardware.co.uk/forum/id-2753844/asus-mg279q-hitting-144hz.html

Furthermore, the OP in that thread says he has come across people using the monitor with GTX970 and GTX980, and they've had no problems. So there's indeed a possibility that there are issues with older nVidia GPUs with this particular monitor.

But yes, the fault could also be in the "Generic PnP Monitor". An inf driver would be handy in that case, as it would override the default driver. Then there's also the CRU (Custom Resolution Utility):
http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU

While that one seems quite complicated (and a VERY long thread, 160 pages :D), many users still recommend it. From what I've understood, using a custom EDID override disables the Freesync. So if you at some point decide to upgrade to an AMD card, you'll have to turn off the override to get Freesync working again.

But, didn't nVidia Control Panel also have some sort of custom resolution and timings -option? You might have to try with trial and error, if the automatic values don't work.
 
Interesting, thanks Aatu. I'll have a look through that thread.
I'm also curious as to what you said about an inf driver? I confess I have no idea what that is. I've been to the Asus website and I can't find any MG279Q driver downloads or anything, so where can I get the correct inf driver?

Thanks
 
Yeah, can't help you with that. I tried to search it myself, but couldn't find one. During the CRT-era, inf drivers were more common, I think. Not sure when is the last time I've seen a separate inf driver supplied by the manufacturer.

But in any case, if you manage to find the inf driver (or another user is willing to extract/copy/create the inf file of their MG279Q monitor with the Monitor Asset Manager -utility (http://www.entechtaiwan.com/util/moninfo.shtm)), the inf driver should be possible to override in the Device Manager. I assume that's the place where the "Generic PnP Monitor" is stated?

I've done something similar before, though I wanted to fool the Windows into thinking I had a Passive 3D monitor that was compatible with nVidia's 3D Vision (I used the Acer HR274H inf driver), while I actually had an incompatible Passive 3D HDTV. Long story short: it worked.

Now that I looked into it again, it's called "EDID inf override". Here's the portion that explains the overriding procedure:
(the process is otherwise identical, just with a different inf-file)
2) Install the HR274H .inf override through Device Manager, to make your system think you have a supported Passive 3D monitor
a) Extract the contents of the ZIP file containing the Acer HR274H .inf override
b) Open Device Manager by opening your Start Menu and typing "Device Manager", then press enter
b1) or right-clicking on Computer and selecting "Device Manager"
c) Expand the "Monitors" category, and right-click the currently installed monitor and select "Update Driver Software"
d) Click "Browse my computer for driver software"
e) Click "Let me pick from a list of device drivers on my computer"
f) Click "Have Disk..." toward the bottom right of the window
g) Browse to the location of the INF file you extracted previously, then press OK
h) Press "Next", then "Install This Driver Software Anyway"
i) Reboot
Ps. Not sure whether I wrote that guide by myself for future reference, or whether I found it somewhere else. If someone recognizes it as their own, they can freely claim credit for it.

Ps2. You MIGHT be able to get it working with ANOTHER 1440p 144Hz monitor inf driver. But if the timings are non-standard in the MG279Q, it might get stuck in an "out of range" mode, or in the worst case (although unlikely) even damage the monitor. The safest option is for another owner of MG279Q to extract the inf file with the Monitor Asset Manager -utility.
 
To be honest I'm reluctant to try stuff like that, because as far as I can tell this monitor should be working at 144hz without any problems. Makes me think that maybe the DisplayPort cable isn't very good. I've heard of people having problems with one DP cable but not another.
 
Ok so on the 120/144hz issue you have I also had it but it was via a different problem.
This is only on Windows 10 insider and then upgraded to full so it didn't happen for me on older versions of OS (as I never had those OS's running on this monitor)

I had an AMD 290X and I was underwhelmed by Freesync and running at 144hz it kept being 'flaky' so i'd get the a random blackscreen flick up as the refresh changes and all of a sudden the 120/144hz and sometimes 90hz became greyed out in the Catalyst software and checking my adapter properties in device manager those were now not listed and monitor was running at 60 or 72. (quite often 60).

So I changed the displayport cable to a new one and this seemed to happen a lot less but still randomly happened which was annoying the hell out of me and I upgraded to a 980Ti as I wasn't pushing the FPS I wanted at 144hz and was getting fed up with freesync on such a crappy range and it never really worked properly (mainly disabling it on all games as the menu screen runs higher than the range and switches it off and not back on...)

On Nvidia it's been fine, I've not really had the issue at all. Some games have had a screw up on alt/tabbing and hz then changed or I had to knock the monitor off and on, but this tends to be really old games (Everquest 2), newer games have had no issues at all thankfully. But that's more been explorer crapping out - I really should clean install windows 10 at some point but hey ho...

Thankfully when I've gone to adapter properties and check on hz and it has maintained 144hz every time (phew!)

So not really a solution as such but I do think that the cable change I made seemed to help a lot so perhaps that's a good start if you have a spare you can borrow from somewhere?
