Looking for IPS with good colours and lowest input lag

What about the BenQ BL2710PT ?

It shouldn't have any backlight bleed associated with bad QC on those LG panels or "IPS glow".

That isn't true. Backlight bleed can be seen on models with panels from any panel manufacturer, it isn't an issue isolated to LG IPS panels at all (nor does it affect all LG IPS panels). AU Optronics are hardly known for their top notch quality control when it comes to their panels either.

And as for IPS glow, that's a characteristic of light transmission behaviour within the matrix. This matrix arrangement of PLS also causes this behaviour (PLS glow if you like) and there is no reason to think that AHVA won't be the same in this regard. It would be fantastic if it wasn't, but that remains to be seen.

Well for a panel that's taken 3 years to design since 2560x1440 IPS was first available and is priced higher than the U2713H I don't see why BenQ have bothered at all if it offers no major improvements. :p

Why couldn't they have just scaled up their 5000:1 1080p panels?

When I first read about AHVA technology towards the end of last year I did actually think it would be a VA based technology for its monitor implementation. For whatever reason, be it technical or otherwise, there are no 2560 x 1440 VA panels in production or slated for production in the near future.

The BL2710PT is marketed specifically as a monitor for a CAD/CAM workflow where the superior colour accuracy of an IPS style matrix is preferred over a VA matrix. I would like to see 2560 x 1440 VA panels (on a more general note), but BenQ definitely had a more significant gap to fill in the market by not having any IPS or IPS-like models in their repertoire. They are always more comfortable using their own (AUO) panels where possible, which is where AHVA comes in.
 
just received my vp2770, WOW :eek: had a quick blast on bf3 and its great, pixel perfect, not sure about bleed, dont know how to test that.
how do you overclock the refresh rate???

so far i'm impressed :D

Good glad your happy with it will be getting this monitor sometime in next couple months just waiting on which GPU I'm going to get at the same time.:)

Sorry Dont know anything about overclocking a monitor never tried to do it an light bleed you use black back ground to see think there is so test programs you can get online need to download them myself so be ready to test mine.

Just wish the stand wasn't so big, pushes it too far forward on my desk, may need to invest in an alternative.
Can overclock in the nvidia control panel, so far not so good under dvi, will give DP a go.

Have you seen this vid review on the viewsonic? http://m.youtube.com/watch?v=YD5MDUKBXig&desktop_uri=/watch?v=YD5MDUKBXig
According to this guy it has the lowest input lag, shame ocuk dont stock them :(

Just read NCX's full review and am slightly confused. PRAD.de did indeed measure 7.2ms of input lag (with an oscilloscope, no less) and that is good for a non-TN panel. However, NCX says that we should add to this 5.2ms for the average pixel response times, i.e., 15.4ms total latency (my own calculation).

Indeed, seems snappy for a non-TN panel, except that I cannot for the life of me figure out where he got the 5.2ms figure! Viewsonic certainly doesn't claim 5.2 but rather 12ms. PRAD's review refers to this 12ms claim but measured the response time as actually being 18.6ms, i.e., longer than a screen refresh takes at 60Hz!

So yes, while the 7.2ms input lag figure is good for a non-TN panel, the total display lag (total latency) would appear to be not 15.4ms but rather 22.6ms.

Perhaps I'm missing something obvious, but I don't think so. From what I've seen so far, NCX missed the part of PRAD's review where they measured the response time as being 18.6ms

EDIT 1: I should point out that 18.6ms for an IPS or PLS panel is actually quite typical. This post is not meant to suggest that the Viewsonic is unusually laggy (on the contrary) but rather as a friendly suggestion to cross-check the claims you see, both by manufacturers and by reviewers. With so many specs to measure, record, evaluate and keep track of, human errors do happen

EDIT 2: Fun trivia: TFTCentral measures this screen's total latency (input lag plus response time) as being 26.2ms. PRAD used an oscilloscope for their input lag measurement, so their 7.2ms figure is almost certainly the most reliable, which means in turn that my 22.6ms figure is probably on the right track.

In any case, I would agree with TFT's analysis that this monitor is good for non-hardcore gaming:

The lag of this screen has been categorised as CLASS 2 as detailed above. As such it may not be quite as suitable as other models for very high end gaming or fast first person shooters, but then again, this isn't really a gamer-orientated screen anyway.

The 5.2ms figure came from the value Prad uses to determine the pixel response component of 'display lag'. It is half of the average response time using the fastest acceleration setting on the ViewSonic. In actuality this isn't really very representative at all as nobody would be using that setting due to the intense overshoot. The 'Advanced' setting, though, is very well balanced.

It is important to separate out the pixel response time and input lag - one contributes to how responsive the monitor looks whereas the other contributes to how responsive it feels. The signal delay, which is what is often considered to be the 'true input lag' is relatively short on the ViewSonic, shorter than any other competing WQHD model from mainstream manufactures like Dell, Samsung and ASUS. It is this signal delay or 'true input lag' that determines how snappy the monitor feels in relation to input. For a fluid/connected feeling though it's really a mixture of input lag, pixel responsiveness and refresh rate (and indeed sampling method - sample and hold etc. but let's not go there) that is important. On the ViewSonic the motion blur is essentially as good as you'll see from a 60Hz monitor and the signal delay as good as you'll see from this sort of monitor. As a result it is one of the best 2560 x 1440 gaming monitors out there from mainstream manufacturers.

Hopefully these concepts will all be easier to grasp when that long-awaited article I'm working on is published ;).

BF3 ("hardcore gaming") is hardwork after using a 120hz panel, looks amazing though, and its something i can cope with. This was a big decision for me, my previous monitor was a benq xl2420t and for FPS games there are none better, BUT, for me the picture quality was very poor. So if i played games especially FPS 24/7 i would have got another but as thats only around 20% of the time i can live with the slower responses and just be in awe of the quality :D
If this panel came with 120hz and had a price tag of £800 i wouldn't hesitate for 1 second, well maybe a few seconds whilst the mrs leaves the room and i can then place the order!!!
 
I don't like games like BF3 think its my age like slower pace games now so wouldn't need 120hz either think the viewsonic will be perfect just hope the stand can be pushed back enough on my desk.

the back of the stand is touching the wall, which makes it 11" to the front of the screen if that helps
 
On my dell 2407 monitor screen is 8.5 inches from back of my desk so 11 inches is huge difference so you have no way to make it less then 11 inches with the Viewsonic stand.
Will need to check this out more that stand makes the screen far too close to my eyes.
I want Viewsonic screen about 7 inches away from the back of the desk because its a lot bigger at 27".

These look good but pricy Ergotron LX arm mount I've got glass desk though.

I think I'm just going to keep my 2407 and buy a benq xl2411t for gaming as its only around £230 new and I can have the 2407 for graphic work.

It seems that there are no decent IPS monitors with the minimal input lag im looking for.

I'm starting feel same way will keep using my 2407 an wait 6 months an see what new models come out.
 
I have 4 monitors already lol still may buy the Viewsonic but don't want spend loads of extra money because the stand is too big that be stupid.

Ergotron Neo-Flex Flat panel monitor stand for £41 looks good should fit the veiwsonic.
