Smearing and blurring are everywhere at 120Hz, and the colors are WACK.I'm interested to see how it works out- for now, I'm holding off on monitors, partly because the market hasn't yet settled with the likes of inexpensive Korean-built high resolution units (with the 27" units hitting 120Hz, which is very appealing), and partly because we've seen just how inexpensively 4k monitors can be built; essentially +20% in net manufacturing cost, it seems.

Don't buy the hype, kiddies. 120Hz IPS isn't really here yet.
Waco wrote:I measured it the only way I have available to me -- subjective comparison against a true 120Hz display, my VG248QE. They aren't even in the same ballpark for fluid motion, even without enabling LightBoost on the VG248QE. I'm talking about the same order of magnitude as the difference between 30fps and 60fps here; night and day, truly not even comparable.Did you measure it or is this purely anecdotal?
Waco wrote:I agree about the first lightboost-enabled 120hz IPS. I'll sell my little sister to get one! (This is a joke.)Interesting. Perhaps that's just a bad example (the response times on my X-Star are excellent)? I imagine the first company to come out with a lightboost-enabled 120 Hz IPS will take the market by storm.
EDIT: Mine won't do 120 Hz, but it does reliably do 96 Hz. It's a very big difference versus 60 Hz and there aren't any issues with color or smearing.

It is the early model you are talking about.and that yamakasi catleap is not the same for overclocking as the x-star and qnix panels happen to be. did the catleap have multi-inputs? that's going to add latency and hurt response time. there was one very special version of the catleap that was stable up to around 100hz but the price became super inflated on them as it was only a certain early revision that would overclock successfully. since then, the newer x-star and qnix panels with single dvi-d inputs have proved to be very decent overclockers. 96hz is pretty much guaranteed and the panels response time is very fast if you go with the single input version. newer panels are popping up everyday so we will have to see if they continue to improve in this area.

I mostly use it for a workstation purposes, but do play a few games every now and then maxed out max res 32AA etc - and I don't notice any ghosting or tearing. But with the Korean monitors you're probably playing a bit of a panel lottery, so you never know what you're gonna get. $650 seems steep to me, I got the 27" for $260 shipped a year ago.
cynan wrote:As far as I know, none of those Korean IPS monitors actually have Displayport 1.2. I don't think anyone's really validated whether dual link DVI can properly handle the bandwidth that close to 4MP at 120Hz requires. Or it could just be that you're right and the ASIC (timing controllers) in the things can't handle 4MP at 120Hz.

That's horrific, I'd send it back if it isn't IPS.

What do you have against PLS?
Airmantharp wrote:It's inferior to IPS in every implementation so far, especially in Samsung's own panels. It maintains the single *VA advantage, which is dark blacks, but not necessarily more 'accurate' contrast, where dark grey gradients are distinguishable.
In every implementation I've seen, mirroring S-PVA exactly, the pre-charging necessary to keep the pixel response in check resulted in the same input lag penalty. Go figure, Samsung.
I was hoping that the technology would be more of a compromise towards the MVA panels- but I've yet to see any evidence that it's much of an improvement over S-PVA, which while effective for video, was/is inferior for gaming and color critical work, both of which are important to me.
auxy wrote:I think you're confusing PLS with PVA. PLS is Plane Line Switching, and is basically Samsung's version of IPS. It's not related to Vertical Alignment monitors at all.

Airmantharp wrote:Just digging into the ASUS PLS review, you can note that they recommend the 'motion compensation' setting to be set at 100 for best input lag results- but that it be set at 40 to prevent pre-charge 'overshoot'. Good fun there, and basically confirms what I was worried about above- like S-PVA, the panel either needs input-lag inducing processing to keep the relatively slow pixel response in check, or you deal with the slower pixel response to lower input lag. Catch 22, so I'll repeat, go Samsung!
