Hi All,

As many of you are aware from my multiple posts i was in the process of upgrading my monitor over the last couple of weeks.

I finally got my new monitor and opted for a Asus ROG Swift PG279Q!

To help others thinking about upgrading their monitor and also to share my experiences, i have listed below what i have learnt and what the monitor is like (photos to follow).

Firstly my main concern before upgrading my monitor was IPS-glow or black light bleeding. After research these are 2 very different things. A really good place to learn the differences is at TFT central (which also recommends you buy your monitor from overclockers):

http://www.tftcentral.co.uk/reviews/asus_rog_swift_pg279q.htm

All this concern about back light bleed and ips-glow actually made me specifically look out for it - and when your specifically looking for something then your likely to find it.

When i unpacked my new monitor and turned it on - i instantly saw ips-glow. Disappointment set in, but since then its become less of an issue when i am actually using the monitor.

IPS-glow is something that is unavoidable with ips panels, but what makes it more pronounced is the size of the screen and the viewing distance. Obviously when getting a new monitor your naturally excited and sitting really close (as i did).

But because i went from a 22inch to a 27inch - sitting at the same viewing distance (about 40cm) i did notice ips-glow in the corners.

However shifting the monitor back by around another 25cm actually made a big difference, ips-glow was reduced.

Its worth noting a curved ips screen will increase ips-glow in the corners depedning on size and viewing distance aswell compared to a flat screen.

So in my limited knowledge of my research in the last 2 weeks - i would say this monitor (the one i have) there is virtually no backlight bleed, but does have ips-glow. The extent of it will depend on your viewing distance.

Saying all of that, and in my initial disappointment and close viewing distance, i took pictures and contacted the store i bought it from (currently in Singapore - so cant buy with OC).

They have agreed to a 1 for 1 exchange when new stock comes in - but with the adjustments i have made in viewing distance, i'm starting to think if it is required. I will post photos for people to opine on later.

One point to note is that no mater on viewing distance, when watching movies that are dark (like batman) ips-glow is always present and never disappears. When playing games, surfing the net or watching bright / light videos i do not notice it - but was really obvious with Batman movie.

So i will see if this is the case when i go to do the exchange on the replacement (if i take it).

Now that the elephant in the room for me (IPS-glow / backlight bleed) is out of the way, i couldn't find any other fault with the monitor.

No dead pixels, no bright / dark pixels - i ran many tests and the screen is perfect.

The build quality is excellent and, for me, i love the design.

This has led me to conclude 27inch with 1440p resolution is the ideal size for me - i'll do gaming but also video editing. I am actually happy i didn't go to 32 inch or 4k resolution (i will wait for these when OLED and graphic card power increases, as then viewing distance / ips-glow is not a problem), i think for my current setup (desk and room) 27inch at 1440p is the sweet spot.

So overall this is how i feel:

Positives:
Love the design
Love the resolution and size - meets my requirements for my usage
Good build quality
No dead pixels or bright / dark pixels
Easy installation

Negatives:
IPS-glow - i'm unsure if this is standard for ips panels and viewing distances or if my monitor has a fault

Summary: this is a great monitor that i feel very happy with. If it didnt have ips-glow i couldn't imagine a more perfect monitor. With ips-glow it may be something i that i live with - depending on whether its a fault or the same as every other ips panel.

I will keep everyone updated on how the monitor performs in the coming weeks and how the exchange goes.

I will also post photos of the monitor and the ips-glow for the more seasoned experts to give their view aswell.

Many thanks :)

Sorry to trounce on your thread (useful feedback for the PG279Q), but that's incorrect. A curve actually slightly reduces perceived glow from a normal viewing position. It is just that the flat 34" AH-IPS panel seems to have less backlight bleed, generally, than the 3800R curved variant. This fact is pointed out on some of your research sources, too.
 
Hmm, TFT central also point out this fact on curved screens for the following reasons - which is also what i noticed:

"We see many reports of users who mistake IPS glow which is a panel characteristic, for backlight bleed which is a build quality issue. This glow in the corners is caused by your angle of vision when viewing the screen and is because of the pixel structure on the IPS panel"...

"The bigger the screen, and the wider the field of view, the more obvious this glowing from the corners will be. On a 34" screen like this (Acer X34) there are very wide fields of view and so you will notice it when sat up close to the screen and viewing dark content. If you move your viewing position back a bit, it will be reduced."
 
to addon on - you are actually correct, curved screen reduces the glow slightly - its the fact that ultra wide screens that cause more glow.

Thanks for pointing it out :)
 
I'm confused. You're saying you're noticing Glow in the corners, but you should be getting glow all over the screen. You havent said anything about BLB apart from the fact you're saying you dont have any, which I find really hard to believe. Are you sure your glow is not being highlighted in the corners by the blb ?

i think you've got it now anyway, but just to clarify - the bigger and wider the screen, the more likely you are to see some glow from the edges from a normal viewing position. it's all about the angle your eyes make with the screen. an ultra-wide just means there's a much wider angle to the edges than a 27" like your PG279Q. curving the screen slightly towards the user from the edges helps a little :)
 
Sharing some photos - is this ips glow or does my monitor have an issue? thanks

Your angular shots show IPS glow primarily, whereas the 'centre' and 'far away' shots illustrate backlight bleed towards the top right and bottom left.
 
ok thanks for the feedback :) - at least now I know the difference and can state this when going for the exchange. They have also offered to test the new monitor in the shop as well, so I know what to look for.
 
Mine arrived today and it also has backlight bleed, though I'm unsure whether to return it. Love the monitor and so far I haven't noticed it while gaming.
 
Computer Lounge opened 20 of these, and they said that around half of them had unacceptable levels of bleed, and by the looks of the pictures they all had it to some degree.

They really need to sort out the QC issue, which is exactly what this is!

I opted for the Acer XB271HU instead and have been much happier with it. The BLB is much lower to me, and the screen uniformity is better.

I think they need to stop using AUO panels personally.

I have same screen. BLB is virtually non existent, IPS Glow is evident bottom right but doesnt bother me at all. I was one of the lucky ones.
However if you read the main thread plenty of people dont like this monitor.
ASUS ROG Swift PG279Q 144hz 2560x1440 IPS G-Sync.

said it before say it again whoever brings out a screen with no blb or ips glow will clean up. Its technologically possible but in the current climate seems like an impossibility.

Maybe but not sure it's just the panel they are using, I think it's also the way the panel bezel is clamped to it, the BLB is often just caused by uneven pressure.

I'm sure in the future this may be fixed, but it's been a longstanding issue with the tech really, and fixing it probably costs more than dealing with the returns - a lot of people probably just put up with BLB or may not even notice it as much.

No way. We can put men on the moon and in space, we can send a solar power plane round the world non-stop, you can use satellite imagery to zoom in on a 1 metre square piece of land yet we can't put together a plastic frame round a LED screen without even pressure and construction because it costs too much to do right ?

Sorry dont buy it.
:rolleyes:

I'm not saying they can't, I'm saying they probably won't!

If you are running a business, and you send out screens like this, and you get maybe 15% returns (completely random number btw). Then sure it costs to deal with the returns, but it may cost them less than actually fixing the problem properly.

Profits are up, customer satisfaction is down, but who gives a crap about that anyway these days?
 
Just thought i'd update everyone on how i'm doing with this monitor.

The jump from 60hz to 120/144hz with G-Sync makes a massive difference, to my surprise, in FPS.

So much so that i cant imagine going back to a "plain old" 60hz monitor.

Whether its the higher refrsh rate or the g-sync or both - games are a lot smoother.

The downside is ips glow / backlight bleed, no way getting around it. When browsing the internet or working you wont notice it, but when playing dark games or watching dark movies you will.

As i mentioned previously i was going to exchange my monitor for another unit due to the ips glow / backlight bleed. However after inspecting the other ones, they all have the same issue!

Instead of a exchange i negotiated a partial refund of 23% and will keep my monitor (still with warranty) - other than ips glow / backlight bleed it is perfect.

Note for the future - next monitor will be a OLED 144hz g-sync - no new monitor until then!
