ASUS PA246Q 24" ProArt Monitor: No Adjustments Needed?
by Chris Heinonen on July 2, 2012 1:30 PM ESTASUS PA246Q - Input Lag and Power Use
There is no overdrive or game mode on the PA246Q, as it is targeted at graphics and design with gaming as something you might do in your spare time. Despite that, it does reasonably well with just over a frame of lag from our measurements. There is a 10ms input delay for processing the image, and then 24ms of rise and fall time for the pixels themselves, leaving to a total lag of 22ms. Your effective lag is probably right around 16-17ms, so a single frame. It isn’t the fastest gaming monitor out there, but it isn’t bad either.
With its CCFL backlighting system, the PA246Q is not a power efficient display. At minimum brightness it uses more power than the 27” HP ZR2740w and uses just slightly less at maximum brightness despite having maximum light output that is only 65% of that in the HP. Of course it does have a much larger gamut enabled by the CCFL backlighting system, but it does take a lot more power to do so.

Just wanted to leave my two cents as I've owned this monitor for about six months now.I've generally been very impressed with this monitor - I have a wide variety of needs and I find it fits most of them. I do some semi-pro video and photography work but nothing too fancy (photoshoots for local bands, that sort of thing), play lots of games and do some Netflix watching and the like. I've been very pleased generally with the Asus display - the colours are great, and a huge step up over my TFT display I had before. I've also noticed no ghosting issues at all in games and movies (I initially replaced my 'old' 24" TFT with a BenQ MVA panel and while the contrast was incredible, the streaking and ghosting was a major distraction).
My only major complaint about the display is the poor black levels relative to newer LED-backlit screens. Compared to my old TFT/CCFL display the Asus is about on par, but it can't hold a candle to the newer TFT/LED and MVA/LED screens.
I've recommended the screen to a couple of friends who are in similar boats to me - people who use their computer for entertainment, but are also reasonably serious about using it for art/video/photography.

"there is no game mode or overdrive for enabling faster response from the display"ASUS's term for Overdrive is Trace Free. Its permanently active in this model (can't turn it off or change the degree).

A very astute observation -- thanks for posting this insightdishayu - Tuesday, July 3, 2012 - link
There are so many cheap 27 inch korean IPS 2560x1440 resolution displays on ebay that sell for under $400. They utilize panels from LG, the same ones used in Apple's cinema display. I would REALLY like to see a legitimate review of them. I'm quite inclined to buy them but i don't want to end up wasting 500 of my bucks. If only Anand could review them somehow?Here's an ebay link. (this is the pixel perfect model, which comes with a guarantee of zero defective pixels)

Basically the only way Anand can review it is if you bought it and sent it to them. They only review what companies send to them for review. They dont buy their own gear.prophet001 - Tuesday, July 3, 2012 - link
It would be nice to see a review of something like that. However, I think it's safe to say that it's not that cheap because it has the same quality as other similarly spec'd panels.dishayu - Tuesday, July 3, 2012 - link
Doesn't apple's 27 inch IPS cinema display cost something in vicinity of 1000 dollars?I just randomly linked this one as it was the first to turn up in my search results. There are monitors selling for around 360 mark as well. And 299 if you don't want a 0 defective pixel warranty (replacement only for 5 bad pixels or more, a couple of pixels out of 3.7 million might not even be noticable at this pixel density but i don't know that for sure)
