Below we bring you some news from AU Optronics about some of their forthcoming panels. Surely of most interest is a new 27" panel (M270DAN02.3) currently in development which will be based on AUO's AHVA panel technology, equivalent to LG.Display's IPS and with very similar performance characteristics. This is a 27" panel with a 2560 x 1440 resolution, 1000:1 contrast ratio, 350 cd/m2 brightness, sRGB gamut and 178/178 viewing angles. Nothing special you might think - wrong! This will be the first IPS-type panel to natively support 144Hz refresh rate, something buyers have been crying out for for a long time! 144Hz AHVA and 2560 x 1440 resolution, we can't wait!

In other areas and in the 27" space AU Optronics are also set to start production on their AHVA (IPS-type) 3840 x 2160 resolution 4k panels. The M270QAN01.1 panel with an sRGB colour gamut will go into production in October while the Adobe RGB version, the M270QAN01.2 will go into production in Q4 of 2014.


Also in 27" size there are some new 2560 x 1440 AHVA (IPS-type) panels coming soon. The M270DAN02.0 with sRGB gamut and the M270DAN02.1 with Adobe RGB gamut go into production in October and December respectively. There is also the M270DAN02.2, M270DAN02.3 and M270DAN02.5 going into production in September with sRGB gamuts. The M270DAN02.3 is perhaps the most interesting as this is the 144Hz capable AHVA panel we already discussed.



Still sticking with 27" sized panels for a moment, we already know about the M270Q002 V0 which was used with great success in the Asus ROG Swift PG278Q. This was the first 2560 x 1440 TN Film panel seen on the market and is manufactured by AU Optronics. AUO also have the new M270DTN01.1 in production now which offers a 2560 x 1440 TN Film panel although it doesn't list 144Hz refresh rate as a feature so perhaps this is a standard 60Hz only equivalent.


Not forgetting their trusty old AMVA (VA type) panels they also have the new M270HVN02.3 planned for October production. This is a 27" panel with 1920 x 1080 resolution and 3000:1 contrast ratio. Still no sign of any 27" AMVA panels with 2560 x 1440 resolution we're afraid. There's also the 21.5" sized T215HVN01.1 AMVA panel which goes into production in October to look out for.

Nice .

When will actual monitors be released?

 

[Grooveriding]

 

[RaulF]

Sure would be sweet if is a amd sync play display, or whatever name is suppose to be called.

 

[DooKey]

This!!!

 

[SoulWager]

So, what exactly is AHVA? The acronym is about viewing angle, not vertical alignment.

No reason for a monitor manufacturer do that when its not a standard. let alone something that would be popular.

It's still vertical alignment:

http://www.auo.com/?sn=1282&lang=en-US

They compare it to "Conventional VA."

Really wish they wouldn't call it "IPS-type" though. IPS and VA are not at all the same thing.

I thought that it was made into a VESA standard!

Te variable sync, witch is what Amdahl doing.

 

[cusideabelincoln]

Does it also support strobing?

 

[omeds]

It states it has similar performance to an LG IPS panel which means it will have the same issues I suppose - concerning motion clarity and response time issues (muddy visuals) at 144hz. The swift still looks like a better option for a gaming display if so.

Well, you assume it will have the same issues. We really don't know though. Besides, this is what a lot of people have been asking for. You might prefer sticking with the TN panels. That's fine as well. Some of us are really annoyed by color shift though and would prefer faster IPS "type" performance.

 

[know of fence]

144 Hz IPS-type panels with pixel transition times longer than a frame, don't make much sense, but a variable refresh rate up to 144 Hz could be interesting particularly for big screens.

I also hope more of AUO's excellent TN panels find their way to market, cause for < 27" that seems the way to go.

 

[BrightCandle]

If you look at the colour transition times for an IPS they range quite highly, but while GtG can be as good as about 8ms the worst case is usually well into the 20-30ms range on all the monitors. Its one of the limitations of IPS. I don't really follow reviews for VA monitors so maybe it does better than IPS monitors when overdriven well but its really got to get down to 4ms maximum to really work well with 144hz.

 

[motsm]

The new VA panel they mention is still just 60hz, unfortunately. Guess I'll keep waiting for something with a tolerable contrast ratio.

 

[3DVagabond]

Not all IPS monitors are as slow as people think and TN panels, even 120hz ones, aren't always as fast as people are lead to believe. Then there is input lag, which panel type doesn't even address.

Looking at this chart you'll see that many companies lie about response times. They claim 1 or 2 ms and in reality their screens are slower, sometimes dramatically slower. Then you look at input lag and it can be 20 or 30 ms. Input lag doesn't affect IQ, but if you are buying a 120/144 Hz monitor for competitive gaming, it'll get you killed.

The Eizo FG2421 rated (IIRC) at <1ms measures 4.2ms. Ask around and people will tell you it's one of the best gaming monitors available. Then look at the Dell 3014, which is a semi pro photo imaging monitor. While rated at 6ms, using the same measurement method as the Eizo, it measures 3.2 - 3.85 ms, depending on mode selected.

Input lag is even worse, and since companies don't rate it, you'll never know.

Eizo = 9.8 - 13.8 ms while the Dell in gaming mode (gaming mode which cleans the signal path) is 0/none.

You can look at others on the chart and quickly see that many specialized gaming monitors are not fulfilling their promise of response times and have horrendous input lag.

 

[omeds]

I think the issue people are talking about is pixel response times - not input lag.

 

[Black Octagon]

Am I the only one who bothered to look this up in the panel database? Although 144Hz capable, the GTG response time is rated at 12ms

 

[3DVagabond]

Yes, but if you look you'll see that there are a lot of false claims by monitor companies. The chart I posted shows both response and lag specs.

 

[omeds]

I thought it was an input lag chart.

And boom there it is.. probably looks as bas as those oc'able Korean displays.

 

[Flapdrol1337]

It'll be ok if the screen has good overdrive. Eizo manages 120hz on mva after all.

And if there is variable refresh you'll still benefit from the 7ms top to bottom refresh instead of 16ms.

Still a bit strange to call it 144hz capable.

 

[Mand]

Which is why I keep trying to emphasize that while you can order the pixels to change 144 times a second, whether they're actually *doing* that is another thing entirely.

 

[monkeydelmagico]

Will wait for independent testing. I do not trust panel manufacturers claims at all.

 

[Madpacket]

I'm not holding my breath for this panel, I doubt it'll bring anything more than an overclocked Korean panel.

We need new screen technology specifically to address this problem.

Maybe strobing can be worked into IPS panels. If they can shutoff the pixel and then turn it back on, it'll never have to go through slow GTG transitions. But then non-strobed modes would still look worse (on G-Sync, which is amazing) than TN panels.

But for now, I gave up waiting on IPS. The Swift, as an 8-bit panel, has very comparable colors side-by-side my Dell U2713HM. But, it has some bad AG coating that makes it somewhat painful for desktop use (has this grain texture where as the Dell is perfect). For gaming, the Swift is just hands down leagues ahead of my Dell. And viewing angle issue are really overblown with TN in general these days.
