Bad IPS glow unavoidable?

I received an Asus MG279Q a few days ago which I will be returning, I should have a replacement arriving some time today.
The reason for the replacement is IPS glow.
I read it's an unavoidable downside to the technology and therefore some glow is to be expected. But I've never had a clear idea of just how much glow is to be expected.
As I said my replacement should be arriving in a few hours. I'm hoping it'll be a better monitor. If not maybe I'll return it again and get another replacement. Or is this whole course of action something of a futile quest?
Maybe this is as good as an IPS panel gets?
Admittedly things look splendid when the image displayed is full and bright colour. As has often been reported it's when there's a dark screen that the problem reveals itself.
Here's a photo of the problem, taken during the day. That glow in the bottom right corner is not a reflection or daylight catching the screen, it's IPS glow.

Am I deluding myself to think that I might be able to get an IPS without this problem?

Thanks
 
Brightness is set way down to 28. More or less following the tftcentral settings recommendation.
So your LG doesn't have a trace of this effect in any of the corners even if the screen is displaying a dark image and your viewing it head on from about 2 feet away?
That's interesting as that would suggest that IPS glow problems are not inevitable.
Hmm.
 
You can't really notice it if the screen is displaying a bright colourful image, true.
But surely this isn't good enough!
I've scrutinised them both now and I would honestly say that they are identical!
Perhaps I have utterly unrealistic expectations.
But then look at this...

His is pretty near perfect, right? So good ones obviously exist!
 
I would definitely say that the problem is more conspicuous on camera compared to the naked eye.
Evsknight, would you be able to take a picture of your monitor displaying a dark screen from your normal viewing position to compare with mine?

Thanks.
 
Yeah, to reiterate, the camera does exaggerate the problem. But it is certainly noticeable.
It is noticeable in that space picture in the video. In fact any time when the displayed image is dark there will be a visible milkiness in the bottom right corner - but it does not appear to the eye as starkly conspicuous as it does in the pics/video.
I'd probably think this was as good as this panel gets had I not seen that video that I linked to in post #10.
So I'm probably going to return it again to Amazon and give it one more go!
 
Thanks evsknight - that makes for a very interesting comparison!

Haggisman - yeah, I said in the video that that 'glow delay' is only visible on camera as it adjusts to the different brightness. To the naked eye it's instant.
 
Well from 2m away the glow would disappear for me too but unfortunately I have to sit a bit closer to the screen - nearer 2 feet - and from this distance it means the angle from which the right corner of the screen is perceived is sufficient for this effect to be visible.
Oh well, I've emailed the retailer, let's see if they can give me a second replacement.
If the problem is still there then I'll get on to Asus as you did Melmac. Incidentally, I'll be very interested to hear what your replacement is like - do keep me posted!
 
Well...
The retailer first said they were going to have their Fulfilment Centre team physically examine other MG279Qs they have in stock to see how widespread the fault was, then if they found a good one they would send me that, if not I'd send mine back for a refund.
Fair enough.
But I just got another message from them now saying that actually they can't do that as the packages are sealed so they could not open to examine. D'oh.
They've asked me for some details so they can investigate the problem, and while they're investigating they said they're going to withdraw the item from sale!
In the meantime, I'm to return this my second MG279Q for a full refund.
Pfft.
So, I'll be without a monitor.
Can anyone please tell me of a 27" IPS 1440p monitor that is subject to Quality Assurance of sufficient competence to minimise the chance of a customer receiving a screen saturated in IPS glow?
144hz would be nice but is not essential.
I will be gaming on this so I'd like good response time and low input lag (so that probably rules out the beautiful blacks of a VA panel) And one of the games I'll be playing is Elite Dangerous - a dark game that will reveal unsightly levels of IPS glow in an instant.
Or is that a quest for something that doesn't exist?
I mean maybe I should be widening my parameters and considering TNs. Just how bad will their eccentricities appear on a 27" panel? Are the colours really anaemic?
Help me out folks! :)

Thanks
 
After the retailer got in touch with me and said they couldn't provide another replacement and that all they could offer was a refund, I thought I'd get on to Asus again to see if they could help at all.
Just because it might be of interest to others, here's their response...

Dear Mr. Jamie,

Thank you for contacting ASUS. We are sorry to hear that also your second replacement monitor is showing the backlight glow. Taking in consideration that this is already your second monitor, it can be that the backlight glow is caused by design.

Although by viewing some of the forums, it seems that there are also MG279Q LCD monitors that do not suffer from the bleeding or at least have a smaller percentage of bleeding.

Unfortunately just as the reseller, we also cannot say that if we issued another replacement monitor, if this will be free of the backlight glow problem.

We are sorry for the inconvenience that was caused.

If you have any further questions, please do not hesitate to contact us.

Kind regards,

Patrick K
ASUS UK Support Team
 
Yeah VA panels look splendid, but aren't they a bit slow?
Also, I'm wanting a 27", 1440p, 144hz(maybe) flavour, and I don't think they exist yet.

I might just go back to my old Samsung SyncMaster 2443 until something better comes along. :(

Isn't IPS glow a feature of the technology? I thought manufacturers had to add a polarizing filter to remove it, and most IPS screens don't have that as it costs more.

I've had two different IPS monitors over the last few years and both have had the glow to some extent.

I understand it is pretty ubiquitous to some extent. But would you say the level illustrated by my photos earlier in this thread is acceptable?
I would almost think 'Oh that's just the way it is' if I hadn't seen pics and videos like this...

...that show that there are MG279Qs out there with VERY minimal glow.
 
Thanks PCM2 - I certainly don't doubt your knowledge - I think your website is great!
So, given that I could not really tolerate the level of IPS glow on my MG279Q, and given that you say the glow does not vary between IPS screens - it is surely folly for me to be considering some other IPS monitor?
I guess I need to look elsewhere.
What I'm wanting is a good 27" 1440 with good game performance (response time, input lag.) and for it to be unsullied (or at least less sullied) by glow.
I'm coming to realise that this is very probably an entirely mythic, 'holy grail' type quest! So having no choice but to compromise a bit, what would you say my best bet might be?
Should I be considering TNs? Are their colours really that bad?
What about VAs? That Philips UHD 40-incher looks grand, but it's too big/expensive/UHD for me! Are there any decent 27" 1440 VAs out there? (Budget £400 - £500 max)
Or maybe my best bet is to stick with my old Samsung SyncMaster 2443 until technology develops.
Suggestions welcome! :)
 
Thanks a lot PCM2.
I don't mind going for a less than 144hz refresh rate. I have a single 980ti - which is lovely - but in new games like Witcher 3 at 1440 I'm not getting more than 60-70fps anyway.
So I'd be happy with 60hz.
I think you're right, I need to have a proper, eyes-on look at some of my options.
Where in north/northeast London might I be able to actually get a look at a nice selection of monitors? I went into a PC World in Stratford the other day and they didn't have any PC monitors at all. Which I thought was kind of ludicrous!

Why not try some of the limited VA 1440p monitors and see if the input lag really bothers you?

If you don't play competitive FPS, you probably wouldn't even notice it.

I've been eyeing up the current BenQ and Asus VA offerings for a while, but am going to hold out and see what AOC's Q3277PQU delivers.

I'm probably being blind, but which 1440 VAs do you mean? I'm having trouble finding many?
 
Oh bad luck melmac!
Is it another MG279Q?

Hmmph.

After my two failed attempts at the MG279Q, a bit of research finds me coming round to the idea of the BenQ BL3200PT - as prompted by krooton above.
I'd rather it was 27" so as not to lose pixel density, and I'm a bit concerned about its responsiveness in games; but it looks beautiful and, being a VA, it isn't smothered in IPS glow!
So has anyone got the BenQ BL3200PT? What do you think?
