[Various] ASUS debuts ROG SWIFT PG279Q 144hz IPS and G-SYNC - Page 783

post #7821 of 9309
Received a second PG279Q today. It's better... but not by much. Seems like dirt? It looks larger than any of the surrounding pixels. Ordered an acer xb1 from Amazon germany so hopefully that will come in stock before the 14 day period on this monitor is over.

I had my fair share of frustration with ASUS, I have returned two 278Qs, waited almost a year for a 279Q only to have it returned as well, and I was wondering if anyone can post a picture with a perfect unit, no blb, no IPS glow, good color uniformity... Does such a thing exists?
post #7823 of 9309
I received my first PG279Q today, ordered from Amazon (U.S.) on 1/29 during a serendipitous moment when it came back into stock while I was checking the page (at Amazon itself, not a third party vendor).

The top side of the box had two layers of factory packing tape, but it turned out to be a December '15 model so I'm unsure whether it had time to be pre-owned.

I've spent the last two hours inspecting the panel (haven't tested the overclock or G-Sync). I can't find any problems with uniformity and there are no dead pixels or dust specks, all of which would have been immediate deal-breakers. BLB is present (mostly in the lower right) but it's hardly noticeable above IPS glow, the latter which is at normal levels for a panel of this size. I'd really have to be looking for either effect in a dark scene to see them.

I thought I had won the panel lottery before I noticed what I think are called "pressure marks" along the lower edge. I am less familiar with this defect so I was not looking for it initially. There are 5 small splotches of irregular size (the largest two about a square centimeter each), shape (I'd best describe them as nebula-shaped), and brightness (some areas exceeding 100% white). They don't show up in photos well, so the image below has been edited to exaggerate the effect. These are most noticeable on light colors and while viewing directly on-axis. But now that I know they are there I can notice them starting at about 25% gray (e.g., in my task bar). I read earlier in this thread that some have noticed their defects going away after a bit of acclimating. Will this kind of thing lessen over time? I'm not sure I can get used to this, and I definitely don't think it's acceptable for a product at this price point.

That's definitely not normal and likely won't improve over time. Return that POS and try your luck with an Acer XB271HU when they get re-stocked. Many people in these forums have had issues with the Asus compared to the XB. I returned 2 PG279s, one of them had something similar to yours. It was a cluster of super bright white pixels forming a small square in the middle of the screen. Although Acer still has awful QC (7th time was a charm for me), it isn't as bad as Asus this go around. Be careful with Amazon returns. Some people in the Acer XB271HU thread have gotten emails from them due to multiple returns.

Thanks, JLP. I've looked into this type of pressure defect some more and found that it's likely to get worse than better. I'll definitely have to return this unit. It's a pity because everything else was acceptable. I've since tested the G-Sync and overclock on it and found that those features to be working fine. The ULMB only works at 85 and 100 Hz (it is supposed to work at 120 too) but I don't anticipate using that feature.

What I did learn through testing G-Sync, though, is that I really can't notice much of a subjective improvement between 144 and 165 Hz. In fact, 120 is already quite smooth to me (and quite taxing on my GPU). Given both the quality issues and my newfound willingness to compromise on refresh rate, I am considering going with the XB270HU. (I really don't like the chin bar and gaudy logo of the XB271HU and would rather deal with the glossy bezel of the XB270HU.) I want to think the quality processes with the XB270HU have been worked out by now, or at least are more mature than for the PG279Q and XB271HU. However, I heard that some people are successfully overclocking their XB270HUs to 165 Hz now too. Does this mean that Acer is now sourcing the same/similar prone-to-defect panels from the XB271HUs in the newest batch of XB270HUs? This would put me back at square one since my rationale for the XB270HU is giving up the latest features for better quality/reliability of an established product.

Thanks in advance to anyone willing to share their thoughts. The collective frustration Acer and Asus have caused with these 165 Hz monitors (to both consumers and vendors) should be ground for legal action.

Hi guys, The local computer company I always buy my gear from has recently tested 20 of these, Here are the results.

Computer Lounge is looking into the backlight bleed of a specific high end IPS panel. We rigged up 20 of these panels and checked for BLB as well as dead pixels.

What we'd like to know is whether you think the backlight bleed on these panels is acceptable for a high end monitor.
If you bought these monitors, would you find this acceptable? This it totally up for discussion so sound off below on what your thoughts are!

For the BLB photos below, we left the monitors at all stock settings- no calibration, turned off all of the lights.
The images were shot with a Panasonic GH4 with settings at f2.0, iso 200 and shutter speed at 1/2 a second. The edited images just had their exposure reduced by one or two stops. The originals are denoted as M(monitor) and the number - M1,M2 etc. The edited images are denoted as M1-E. The reason for editing was to better show the BLB and a more realistic representation of it, as it's hard to do with just the camera alone.

Two Strawpolls here
How many have an acceptable amount of BLB?

Would you return it or keep it?:

Pretty terrifying, They even posted a nice disclaimer on the product page,

Please Note: These units have been opened and tested by Computer Lounge for quality control purposes, to make sure you get the best screens possible.

All monitors are susceptible to backlight bleed of varying levels depending on the panel technology, bezel thickness and other miscellaneous factors.
Make sure you adjust your brightness settings to a suitable level.

* Backlight bleed will not be covered by warranty until we get confirmation from Asus.
* When the display panel face is aligned to the front, the indication arrow on the base (stand) will be misaligned by about 1 degree. This does not effect the performance of the display at all, but is not covered by warranty until we get confirmation from Asus.

Whoa! That's awesome of that store to do this. Thanks for posting it. Checked out the link, I would keep 5 out of 20 of those monitors. Specimen 13 / 13E FTW, in my opinion. I just give a big thumbsdownsmileyanim.gif to Asus.

Received my 3rd unit today.. haven't opened it.. it's a December model based on the FCLMQ serial number though.. Praying it's decent! No QC sticker and doesn't appear to have been opened at all.. from Newegg.

I can sense ......

Backlight bleed in lower right corner....


Yellow tint - not that bad - but its there....


Perhaps also.... a speck of dust or a stuck pixel!


If my visions are true... I should have atleast two out of three correct!
