Awesome, thanks for the insight. Shame this monitor costs way more than I'd be willing to pay, but it is great that we're finally seeing higher resolution 120Hz (possibly strobed) monitors.

VA panels are known to have superior blacks/contrast on paper, but in reality thats not the case.


Its like those PSU ratings, 700W for 30$, but its peak measurement not constant. For example, what use of high contrast, if there is no detail in the blacks? you cant see the grey tones, there is color shifting, and so on. And you get results like this..



Pay atention to the vest, and the cracks in the rocks in the bacground...there is no details, only black so for movies you will see only figures in the dark parts, no details what so ever, which is super mega giga annoying.



Look at her hair on the right corner, no details like i said, and obvious over-saturation - loss of detail.



Again, missing details.....

This, this and this....The qnix qx2710 pls has this problem too with its "deeper blacks". I despised and sold it....

TN or IPS. Better be IPS, if its TN, that price is awful!

120Hz a placebo? rolleyes.gif

I guess you need to be good at twitch shooting and doing things at a fast rate to notice.

120 Hz does nothing for anyone's performance in a game (unless you are one of the people who gets motion sickness without 120 Hz).

It's all a placebo effect.

I've used 120 Hz screens. They're nice. Much nicer than 60 Hz. But the color shift/junk viewing angles from being TN is just god awful and I can't stand it - gaming or otherwise.

I'm pretty darn certain it's probably TN, due to the 1ms quotation.

HOWEVER........

A refresh cycle at 120Hz = 1/120 = 8.3 milliseconds. With a strobe backlight, you can bypass the vast majority of GtG under certain conditions. 1ms effective measured persistence an IPS/VA is actually theoretically possible with the following:

(1) Backlight strobes of 1ms each, on clean, fully refreshed frames.
(2) Aggressive pixel driving techniques to hide the remaining 7ms in total darkness. Basically, squeeze the remaining pixel transition (GtG from one color to another) completely into the 7ms dark period between backlight strobes.
(Example: high speed video of LightBoost)

As long as you can squeeze the GtG into total darkness (backlight off), the GtG can be messy (unseen to human eyes) for a whole 7ms. What's matter is the LCD is done refreshing and clean, during the final 1ms, during the backlight strobe. You see, mathematically, backlight strobes can be shorter than GtG. Motion clarity becomes dictated by the length of backlight strobe (persistence).

Remnants of transitions need to remain well under 5% (e.g. less than 5% crosstalk between refreshes) in order for the motion clarity effect (of typical game material) to be clearly dominant. On several good TN panel, some transitions are so complete that transition inaccuracy by next refresh is below human vision noise floor (e.g. like the difference greyscale level 254 versus greyscale level 255). At this point, GtG totally, completely ceases to be the limiting factor in LCD motion clarity, and the length/brightness of the strobe becomes the motion clarity limiting factor.

VA just barely reached this stage (EIZO's FG2421, especially when warmed up), but I'm not sure if IPS has reached this stage yet.

My bet is it's probably an IPS monitor. check out their existing PB278Q monitor. I bet you they literally slapped in a G-Sync module and OC'd it to 120hz and called it a PG278Q

https://www.asus.com/us/Monitors_Projectors/PB278Q#specifications

If that's the case, then it may be an IPS monitor.

Yes, unless you've set strobing to 100 or 110Hz. I play BF3/4 at 100Hz strobed because getting 120 consistently is quite difficult, almost exponentially more difficult than getting an almost steady 100FPS.

Try it on any IPS and most VA panels -- you won't be able to read the street name labels.

Only strobe-backlights (including LightBoost, GSYNC's ULMB, Turbo240, BENQ Blur Reduction) successfully pass this test.
60Hz = baseline
120Hz = 50% less motion blur
strobed = 80-95%+ less motion blur

This is important for people who adore CRT motion clarity, fast panning/strafing/turning with zero motion blur.

I'm betting this monitor that ASUS announced, includes a strobe backlight.

But we are talking generally here, not only for gaming monitors, i was responding to the user who wanted to know why IPS own VA smile.gif

Here is another example btw,



Look at the the sides of the picture, the rocks....no details in the blacks = useless.
