I have it, and it's been already mentioned a few times by others in this thread.

Though I don't think it has to do with G-Sync enabled, because I have it disabled it's still happening. I also think it has increased in frequency over time.

I haven't seen any comments on a firmware upgrade fix; do you have a link? I only read one review on Amazon once, where the customer send it in for repair but Acer supposedly didn't recognize the issue and just returned it (probably because it's happening so infrequently and they're lazy bastards).

.

All five of my monitors that I've tried have displayed this problem. I have tried a new display port cable a different GPU as well. Here's a link to another person that has the same problem https://community.acer.com/t5/Predator-Monitors/Anyone-have-the-XB321HK/td-p/418682. Here is a couple of reviews on Amazon from the 27' version. It sounds like the same problem.

"Acer has an acknowledged firmware bug that is causing a display issue that shifts one half of the screen, as if it rolls over itself. You will see two vertical lines where the center of the screen is and where the edge of the monitor is. Sometimes this happens to the right half of the screen, sometimes to the left half, and is affecting everyone who owns the monitor as far as I know. As of this review (6/2/16) they have only just acknowledged the issue and there is no way for owners, we're told, to update the firmware themselves! Though they have not given us any confirmation of what they want us to do to fix this, they've eluded to us all shipping our monitors to one of their service centers. They have not yet told us whether they expect this to come out of our own pocket, but I assume that will be the case.

So consider with your purchase you will have to do one of the following:
-Tolerate turning off and on your monitor daily to fix the vertical line issue, indefinitely.
-Taking your brand new monitor to an Acer Service Center (might want to look them up first to see how far you are going to have to take it, don't be surprised if Acer tells you if only certain centers can update firmware)
-Shipping your brand new $700 monitor to acer, probably at your own expense

They won't let me provide a link to threads about this on Acer Predator forums, but they are there. No way I would purchase a new monitor unless I was guaranteed it had the updated firmware, nor could I let someone do that in good conscience."

"Please don't give Acer any business until they fix a pretty major flaw with this product and deal with all of the inventory that they've already sold to places like Amazon.

Before I start, let me say that, aside from this annoying problem, it is an amazing monitor and I absolutely fell in love with it at first. There is an issue where a vertical line of pixels from the middle of the screen will end up on either the left or right edge of the screen. At first I blamed my video card and the DisplayPort cable that came with the monitor. I should have checked the Acer Predator forums first.

They know about the issue and they want you to bring/send the monitor to their Acer service center to get the new firmware applied. Seeing as this was only announced last week, I imagine it will probably take awhile before new monitors can be purchased with the fix already applied.

This is my first Acer monitor, and it will likely be my last. I only hope this review can stop others from making the same mistake I did."

Here's a review of the XB321HK from Amazon.

"This 32" IPS UHD monitor comes with G-Sync. As such, you pay quite a price premium, so you'd better expect top-of-the-line quality. Unfortunately, the Acer XB321HK falls far short of a product that deserves to be priced so highly. My first purchase of this monitor had two dead pixels and many, many what I'm going to call "sub-dead" pixels. In the picture attached to this review, I held a camera less than an inch away from the screen displaying a solid black image. You can clearly see the red dead pixel in the middle of the image. However, all the other pixels you see that are not black are what I call "sub-dead". Their off-color is only able to be seen by getting very close to the screen -- closer than is safe/comfortable for viewing, so not something you'd notice. Still, the clear lack of quality in the entire screen is apparent.

I have seen other reviews here that complain about backlight bleed; I did not test for this. The viewing angle alone from such a large monitor does cause color distortion but that's the fact of the technology -- a problem different than backlight bleed.

I have seen one other review that complained about glitching/flickering. This *is* something I encountered with this monitor. Using the same DisplayPort cable with a different monitor (23", 1920x1200 IPS) I have no issues and have never seen flickering for the two or three years I have used it. However, this monitor, on average one occurrence every two hours, will have a less than one second flicker/glitch where either the entire screen will quickly go black and come back, or a vertical strip of varying length of the screen will quickly flicker to a corrupted red/green mix and then fix itself just as quickly. I say "on average" because it certainly isn't predictable, but certainly will occur given enough time.

The flickering I can deal with: it's only something that happens 0.001% of the time. The sub-dead pixels I wouldn't have *too* much a problem with, since it's not apparent once you are greater than six or eight inches away from the monitor; because the monitor is so large you must be further than this distance anyway in order to see the screen. However, dead pixels on delivery simply isn't acceptable for a >$1K monitor and so I am returning it for a replacement.

If the replacement also fails quality standards, I will likely find a non-G-Sync 32" IPS UHD monitor from another company with higher quality."

i got the same problem you guys are describing the flicker, not so good backlight bleeding, and dead pixels are coming up, but i heard nightmare story's about acers warranty service, guys wasting 3 months sending it back and forth and getting no service done on the monitor at all. infact i believe acer told them that they do not replace lcds at all period... if that's the case what the hell are they doing then, anybody got any info on this, i to own a XB321HK and want to exercise my warranty which i am entitled to, somebody should file a class action lawsuit against them.

btw whats there dead pixel policy on the XB321HK, also has anybody done a rma with the XB321HK (there flagship) recently, how did it go... acer warranty department scares little kids at night mad.gif


edit: i have the feburary 2016 build of this monitor rolleyes.gif definitely thinking about rmaing

Jesus...
I have just read this whole thread for hours. As well as researched this monitor for 10 days everywhere I could look.
I was so excited reading the thread, close to happy, I could feel my heart racing...this last page really killed my excitement.
Tomorrow, I want to ask you guys some questions. It's getting late here in FL, so heading to bed.
Hope i do not get nightmares over flickering screens.
post #275 of 362
Here is my situation. Any advice would be appreciated.
My frustration with 4k dates back to 2013, at which time I was an early adopter of the Sony XBR65900A. Although it is a great TV, I was never able to watch any 4k, because the Tv did not accept any USB thumb drives with 4k content on them. We basically just used it as a tv, and forgot the 4k aspect of it.
To date, I have not seen any 4k yet, apart from a few Netflix titles that are supposed to be in 4k.
In 2013, I also had a PC built, with dual titans (early model titans).
I listened to a friend, who helped be build the computer, and he installed a P8Z77 WS (LGA1155) , motherboard and a Intel Core i7 3770K.
I have 3 Asus monitors ASUS VG278HE (144hz), which give me plenty of real estate for illustrator photoshop etc.
I play first person shooters, on one of the 27". Been playing first person shooters since Quake1 in 1997. I mostly play far cry 3 and 4 and Doom. Spanning Doom or far cry on 3 x 27 monitors is not acceptable, too much load for the two titans. There is considerable lag.
However, these days, I am mostly working and doing a lot of photo editing, and have little to no time to play.

The idea of getting the 32" Acer IPS with Gsync is very attractive, because, in theory, it would fulfill my dreams of finally seeing some 4k content from you tube, and also doing some gaming,as well as my productivity work.
I am not prepared to upgrade the PC though just yet. Sure i could buy the 32" monitor and add a 1080 to replace the old titans.
Apparently, my motherboard may not have enough lanes? Or is it the Core i7 3770K that is also not capable of handling any newer cards?
In fact, the friend who had advised me right from the start was making a mistake with the motherboard and processor, because even with two old titans, it was creating a bottleneck. I am not sure I quite understand this lane business.

My understanding is that without upgrading motherboard and processor, and video cards, it is pointless trying the Acer 32", is this correct?
Couple all this with the fears of reading through this thread, the flickering issue in particular, is worrying. I am not worried about the ips bleed or a few dead pixels.

Possibly the best solution to my problem is to continue playing on the 27" TN 144HZ, and have a secondary 4k monitor to do my work and watch some you tube 4k content.
I really do not think the old titans will give me any significant FPS in games with this new monitor. Moreover, games which allow SLI are rare. I know doom 4 does not. I'm lucky if I get more than 20 FPS on one titan with the 32" acer.

I am also worried about windows 7. I'm scaling to 125% now on my 27" which is only 1920x1080.
Ideally, I should spend at least $3'000 on a new motherboard, processor and ddr4 ram as well as two new video cards.
But many people have told me to wait until next year to do this. The problem with waiting is, that frustration grows, and by the time the wait is finished, there's a new reason to wait. Then we eventually die waiting.

What other options are there in 4k? I do not want any TN. Are there any MVA panels with gsync? Someone told me Samsung was coming out with new gaming monitors next year?

Guess I was lucky, my XB321HK is gorgious, even backlight glow, no dead or lit up (sub)pixels and no weird lines or distortions/lines/flicker.

I feel for you guys, as with a perfect panel this screen is the most beautiful thing you've ever seen.

I must say I have now bought a LG34UM95, XB321HK and XB271HU (and two Led TV's) in the last 5 years and they are all without a single imperfection.

Sometimes I think vendors cherry pick monitors for different countries / stores depending on regional law. Like EU and especially my country is very pro-customer and in my country you can practically 'test' about any product for a month and send it back within that time and get a full refund.

I have an XB321HK, and while i do get the same flickers, i can safely say that it's really not that big of an issue. It only happens maybe once every few hours and only for a split second; and i've yet to have it happen ONCE during gaming, only during web browsing. (come to think of it, i don't even recall seeing it on the desktop either. I think the ONLY time i've ever seen it was during web browsing. I've had the monitor for a month and a half and it's only happened maybe 30 times in that whole time; roughly once a day (then factor in a handful days that i didn't use it etc..)

Not sure where you heard this info from, but an i7 3770K and motherboard would be perfectly fine for this monitor. The thing you have to understand is, the higher the resolution the less CPU power matters. When you increase resolution you are basically shifting more and more of the workload onto the graphic card and off of the CPU. Seriously go look up 4K CPU benchmarks, you'll see things like the AMD FX 8320 being just as fast in gaming fps as like an i7 4960X six core etc.. this is because the extra power of the six core i7 just isn't being utilized as most of the work is being done by the GPU due to the higher pixels.

And no, games that allow SLI are not rare; in fact there are more games that support SLI than not. I'd hazard a guess that around 70-75% of modern games support SLI at least decently. It's true that DOOM does not but that's literally the exception, and DOOM is not that demanding, even at 4K i can EASILY get 60fps even with a single GTX 1070 or 1080.

The only reason your old TITANs are getting low fps is because they are significantly weaker than newer cards; it has nothing to do with a "bottleneck". And PCI lanes are easy to understand really. Your 3770K has 16 lanes, and each Graphic card needs 8 lanes to function in SLI, so your 16 lane 3770K works with two graphic cards perfectly fine! For a 3rd card you would indeed need to upgrade, but the new pascal graphic cards are limited to 2 way SLI for the most part anyway.

Overall the original GTX TITAN is actually only about as fast as a GTX 780. For reference, a GTX 980 TI is roughly TWICE as fast as one of your TITANs. And since SLI doesn't add a perfect 100% extra power (more like 75%), you are getting about 1.75x the power of a GTX 780, which is roughly about the speed of an overclocked GTX 980 or GTX 1060. If you got a pair of GTX 1070's for example, you would have MUCH more power! Just ONE GTX 1070 is already as fast as BOTH of your TITAN's, and having two of them would give you around the power of FOUR of those TITANs.

If you want true 4K at 60fps you have a couple choices that are quite good.

A) Get two GTX 1070's. When in a game that supports SLI you would easily get 60fps at 4K in most games (only the ABSOLUTE most demanding games would drop below, and only with maxed out Ultra settings and high anti-aliasing etc.. which isn't necessary at high resolutions)

B) Get two GTX 1080's. This gives you about 25% more power per card than the GTX 1070, meaning that even in games that don't support SLI you will get around 45-50fps or higher even in modern demanding games with Ultra settings. In games that DO support SLI you're basically guaranteed 60fps in 4K.

C) Get the new GTX TITAN X Pascal. I have two of them, and even with just one of them i am able to get 60fps in games like Witcher 3, Far Cry 4 etc.. with basically everything turned up. In Witcher 3 i run with all normal settings on Ultra, i use HBAO+ etc.. i use hairworks with 2x AA for the hair, and i disable the in-game anti-aliasing and put on FXAA or something similar using the Nvidia Control Panel; and i never dip below about 55fps EVER at 4K resolution, and most of the time i sit closer to ~65-70fps or so. And Witcher 3 is still one of THE most graphically demanding games out there. Using two of the TITAN X's my average FPS with EIGHT TIMES AA, Hairworks, HBAO+, In-game AA maxed out, all Ultra etc.. is 85fps, sometimes going as high as 95fps and never dipping below 75-80fps or so.


Which one to go for depends on your budget. If you're really strapped for cash i'd say either go for the SLI GTX 1070's (perhaps just get one now and the other later), or get a single GTX 1080 for now and try to save for a 2nd later if possible. If you can afford a couple 1080's then that's probably the most cost effective way of getting good 4K in most games. However i still think that a single GTX TITAN X Pascal is the best choice if you can afford it; it has 12GB of GDDR5X VRAM on it, it has 50% higher
memory bandwidth than the GTX 1080 (and the 1080 already has a quite nice bandwidth) and once you overclock the TITAN X Pascal to 2,000mhz (yes it gets that high) you get around 40-45% faster speed than a GTX 1080! (with water cooling i'm hitting 2,100mhz on these TITAN X's)



ALSO, one more thing to consider. If you are wanting a high resolution monitor, but aren't too keen on spending a crapton on graphic cards for this 32 inch 4K G-Sync one; then i'd say the Acer Predator X34 or the ASUS PG348Q are great choices for you. I also have the X34 and it's a GREAT monitor! It has a resolution of 3440 x 1440, so higher than normal 1440p but not quite 3840x2160 4K; it can be tweaked to hit a 100hz refresh rate which makes movement and gameplay a bit smoother and less blurry, it's still a very good quality IPS panel with great color etc.. , it's a 34 inch monitor with "ultra-wide" 21:9 aspect ratio (games look INSANE with this extra horizontal space, it basically gives you FULL "peripheral vision" letting you see enemies coming from the side that you normally wouldn't) and it's a CURVED monitor too which makes it very immersive, filling your entire vision and pulling you into the game real well. And if you use the Dynamic Super Resolution option to change the rendering resolution to something liek ~4587 x 1920 you get an image that looks fairly close to 4K (not quite as detailed, but it DOES look sharper and very crisp. It's basically like having 16x Anti-Aliasing on, or if you are familiar with Ubersampling or Super Sampling it's similar to that) and you can turn it on or off as you wish.

Overall it'd be a great monitor for you to compromise with, as your two TITANs would actually be able to achieve 60fps or more at 3440x1440p without much problem really; and you could even max out the 100fps/100hz using a single GTX 1070 or GTX 1080 in many games like DOOM.

it happened to me during gaming, the half screen flicker, its a punch in the gut when you pay for an expensive item, just to have to deal with this crap, the company has to issue a repair of some sort, i'll file a petition and have them sued the **** out of, i am unstable as the current monitor i'm using, this sucks


edit: they'll either fix my problem or refund me, i'm seriously now considering getting a dell up3216q, it has much better color reproduction, i've never really had issues with vsync, because i know you need gpu horsepower to drive certain games at insane resolution, infact from what i've seen certain games i believe were preforming actually worse with gsync

I think we owe a huge thanks to Dark Ideals. I, for sure.
How many of us knew that a computer CPU is not that important since our graphic cards are doing 90% of the work when it comes down to the large 34" or 32" monitors?
I certainly did not know this.
Basically, Dark Ideals has just saved me a ton of money and frustration, since I was going to upgrade mother board and CPU before buying a monitor.
He also owns both the 32" 4k and the 34", and it seems there is not much that difference in clarity between both.
In other words the extra investment in Video cards needed to run the 4k may not be mandatory.
I think most of us are tortured by the decision in between buying the 32" 4k or the 34" @ 3440 x 1440 ? Also which video cards to buy.
His post really answers all these questions.
I also learned that a Pascal titan could be water cooled. I had no clue.

I still feel safer with the 34" @ 3440 x 1440. When you get to my age, you are more averted to risk. The 32" seems like a riskier choice.
