[Official] Asus PB278Q & PB278QR Thread: Read the 1st Post - Page 11

post #101 of 1502
Howdy OCers... Since I lurked around this thread for info on this monitor, I thought I'd give a little back. I don't see that anyone else has mentioned it yet (apologies if someone has) but...

The PB278Q uses PWM.

Here's my ghetto phone camera test as posted over at [H] demonstrating such.
@20 brightness
@100 brightness

The side effects are definitely visible during gaming and whether it's just in my head or not, I'm perceiving a 'vibration' effect when staring at the desktop @25 brightness. Won't affect everyone, sure, but will be a dealbreaker for some. Knowledge is power and whatnot.

I understand how PWM and works and how it can cause problems with LED backlighting for some people, but I don't have any actual eyes-on experience with the phenomenon. As I understand it, though, there are few if any LED monitors out right now that don't use PWM. I've used several LED monitors over the past few years and never experienced a problem, but they were all TN models (my home gaming monitor currently being the ASUS VE258Q).

Is it likely that the PB278Q would cause side effects for me if I haven't experienced them with TN LED monitors?

There are actually a number of LED monitors that don't use PWM, such as the Apple Cinemas, the popular/cheap Crossovers, a number of Samsung flavors including the S24A850DW, S27A850D, S27B970D, Viewsonic VP2770, the Dell 2713hm, S2440L (and probably others in the new S line) just to name a few. I wouldn't go so far as saying PWM is no longer mainstream, but it does seem to be on its way out with newer LED models.

But I went from an old, 1 frame+ pixel response, CCFL backlit monitor to this and the difference is definitely noticeable since I was used to a much more blurred effect during motion. Subjective difference to be certain.

Still, in my completely not-remotely-expert opinion, I don't think you'd see a difference, already being used to a number of LED back-lit monitors, though I'm not finding info on the VE258Q specifically. You can always test it yourself just to know for sure.thumb.gif

Has anyone had q/c issues with this monitor? I've gotten two in a row so far with multiple clusters of dead pixels on each, right around the center of the screen... Hoping the third time's the charm or it's time to get a dell u2713hm instead...

Too bad the monitor looks great otherwise.

So whats everybody's brightness and contrast at?

It's here: http://www.tftcentral.co.uk/reviews/asus_pb278q.htm
1 frame lag, not the best possible, but still great.

So now for me it is PB278q or u2713hm...not sure which one to go with...

Is the overall picture quality the same on both?

I just got my PB278Q today from Scan Computers and am using while I type this. This is the 4th 2560x1440 monitor I have had, the other three being a Crossover 27M, a Dell U2713HM, and a Samsung S27A850D. I would like to think I have enough experience to be able to make a fair judgement.

First thing I checked was dead/stuck/bright pixels... there are NONE.

Then I have checked for back-light bleed. There is some but it is very minimal and the same or less than on the Dell U2713HM. Totally unnoticeable during normal use (I never use my computer in an unlit room but for the purposes of testing I did try it and the bleed is next to nothing).

I have not touched any settings whatsoever out of the box and immediately I can tell you that this screen has the best image I have seen so far. The semi-gloss is perfect for reading and typing text, everything is super-sharp and crisp. It is not dull at all but also does not strain the eye. The height adjustment is just fantastic as I can lower it to just a few centimeters off my desk, whereas my Crossover 27M always sat too high even on the lowest setting. The glossy finish on the Crossovers gives it the Apple Cinema look which the Asus does not have, but don't let this fool you. If you are doing any kind of design or development work then you should go for non-glossy. I spend hours in front of my monitors and the glossy ones strain my eyes much more but I will concede that they are more beautiful to look at.

I can 100% recommend this monitor as THE ONE. This is the monitor that we have all wanted (or least me) which has amazing image quality, wide viewing angles, a decent price, good build quality and a great stand.

So you'd definitely spend the extra on this ASUS over a Korean monitor?

Yes but that is because my Crossover 2720MDP Gold Pivot broke after just three months and it cost me a lot of money to send it to Korea for repair. Basically any saving made on buying a 2720MDP Gold Pivot (which is the only model comparable to the Asus) is immediately lost as soon as a fault happens.

If you just want a cheap 2560x1440 monitor and don't care for the inputs like Displayport then the 27Q is perfectly good. I need Displayport to connect my laptop the monitor and get the full 2560x1440 resolution so for me the Asus is the best choice.

Also I should point out that I am not a gamer (not on the PC anyway) so the Korean ones may be better at that task - I simply don't know. I spend hours and hours in front of my monitors either doing audio production or web development work. I would be most happiest spending the time in front of the Asus than my other monitors.

The Dell U2713M is also very good but it has odd faint diagonal lines across the screen which I think is to do with the AG coating. It was bad enough for me to return it to Dell even though I liked everything else about it.
