Acer Predator XB270HU Vs Asus ROG Swift PG278Q

Nobody can really say until the Acer is launched, any opinions would just be surmising :) One could assume the Acer superior due to its 144hz IPS type screen but until it's tested we don't know.. It might have all kinds if issues for all we know :eek:

Me I'm very interested in purchasing the Acer but I'm very concerned it could be a stinker for all I know.
 
After years of stagnation, It's a mad crazy time to buy a new monitor at the moment. The new Acer sounds like a step in the right direction, but as a rog swift owner I'll be skipping the Acer for sure, and I think my next screen will be...

3440 x 1440 superwide
Possibly curved
Ips or VA (leaning more to VA now after getting a VA sony tv)
120hz
Gsync/ freesync (whichever is best)

I thought this would be years away, but the way things are going I think it may come sooner than later.

Only thing is worrying is response time but most people say they really don't notice

Depending on what Acer has done, they may very well notice if coming straight from a ROG Swift.

If Acer has added a buttload of overdrive then they will notice overshoot/ghosting with 144Hz enabled and overdrive on full.

If Acer has not added a buttload of overdrive (and the real response time is closer to 12ms) then there will be smearing at 144Hz because the pixel transitions cannot keep up with the fast screen redraw intervals.

I hate to say it, but I fear this monitor will only perform comparably to the ROG Swift at 144Hz if there is some new AHVA panel tech that has yet to be picked up by TFTCentral and which somehow manages to have an 'authentic' 3-5ms response time. That would be truyl revolutionary, though I'm not holding my breath
 
Well, when you search around you do find lots of people talking of the IPS 120hz Korean monitors that have been around for a while now, and although it can be a lottery with QC on those, if you get a good one they perform very well by most accounts. So hopefully that bodes well for these news one coming out.
 
I'm really happy with the Swift although if the Acer is better then i'll swap it out. The Korean OCed panels still have awful blur compared to the native TN panels but this Acer is using a totally different tech so I don't think it's wise to compare them.

It's funny that so much new Monitor tech arrives at once, it was impossible to hide the Swift from the wife as it was a different size to my old screen, the Acer should be easier though as it's another 27". :D

More blur than TN? Most probably.

That said, I would advise against generalising about these 'Korean' screens. The PLS panels in the QNIX, for instance, have worse smearing when OC'd than do the IPS panels in the Catleap/Overlord. You also have various anecdotes on the internet that are unreliable, because they appear to be from people with the 'wrong' screen (multi-input models that skip frames). The long and short of it is that no professional review site has done an in-depth response time analysis of the 'real' overclockers - i.e., oscilloscope and photosensor for measuring numbers, combined with screenshots from PixPerAn - while in an OC'd state. If I'm wrong about this and someone can LINK me to such an analysis, I'll happily eat my hat.

What I can say is that I went directly to an IPS @ 120Hz from a native 120Hz TN. While this TN was not in the same league as the ROG Swift (it was a Samsung 950D) I literally noticed no difference in terms of motion blur, and 120Hz on the IPS seemed just as smooth and responsive.

Having a TN and VA beside each other for years I can safely say that the Acer Predator is in my basket, along with another 970 Infinity Black and the Samsung external optical drive. Bring on GTA! :D
 
it's really too early to tell how the new 144Hz AHVA (IPS-type) panels will perform which is what the Acer XB270HU will be based on. They've been in development by AU Optronics for a while now and will be the first native 120Hz+ panels of this type developed. the limitation with IPS panels has always been the response times, as there's little point pushing a higher refresh rate when the response times can't keep up with the frame rate requirements. The pixels need to be able to refresh at least every 6.94ms overall to be able to keep up with 144Hz refresh rate. up until now a good IPS panel (without massive overshoot problems) has been able to get down to about 8 - 8.5ms G2G average at best.

So the real test will be whether AUO have managed to get real life response times down to <6.9ms G2G average consistently. i expect they've managed to achieve that, but the second test will then be whether they can do it without introducing noticeable overshoot problems. we will have to wait and see, but as soon as i can get my hands on one i will be carrying out full tests at TFTCentral to see how it performs :)

The Korean OC'able models might be able to reach >100Hz, but from what i've seen the overdrive circuits are very poor, or none-existant and so response times are probably 10-16ms G2G commonly. that's why a lot of people like the improved frame rates and smoothness, but complain about the motion blur.

I just hope reliable reviews come days rather than weeks after release as i just wont be able to bring myself to drop £500 on a monitor without it being tested by someone who knows what they're talking about.

Good post, Badass. I still don't believe any professional response time measurements have ever been published for the Korean OC'able monitors, but in any case with mainstream-brand IPS-type monitors finally starting to ship with high refresh rates, we don't have too much longer to wait.
 
I am waiting for the TFT Central review. I have the QNix at 8ms and have gotten used to it comming from a Asus ROG swift, so 4ms if true would be a gained improvement even though it is not 1ms.

The HUGE advantage for the XB270HU is that it is IPS , which should not have the artifacts the Asus has as a TN panel (vertial lines when moving horizontally with certain colours).

Also it is native high refresh rate without having to overclock.
