Achieva Shimian QH270| $400 IPS 2560x1440 Korean Monitor

NCX, you mean minimal input lag, yes? Because I've never seen an LCD display without ANY input lag at all.
 
Most displays I would classify as having "no input lag," have 2-3ms if we look at PRAD.de's reviews.

85hz works on my S27A850D

What refresh rates can you do at 2560 x 1440?

Over at OCN some users says they can get 70hz from their Shimian.

At 2560 x 1440 my only options that are showing up is 59hz and 60hz.

I am only running two HD 3400 cards, one for each monitor. Not sure if a better card would allow me to go higher. I plan on upgrading but not for awhile. Need a 7970 first for my gaming rig.

These monitors with the glass and no AG at 2560x1440 look absolutely amazing. :eek:

I think the number of reports is a bit low to draw any conclusions about dead/stuck pixels. Considering that they all use the same panel (AFAIK) then I don't put much stock in the idea that one would be any better than the other. Also, looking at the poll just now the Acheiva defect rate is 22% vs. 20% for the Catleap.

I wish the poll had different options for type of defect. I wouldn't be too bothered about dust behind the tempered glass since that's probably easily fixable.
 
I don't want to veer too far off topic but it just goes to show that manufacturers all along *probably* had no interest in designing an IPS monitor with higher refresh rates. That's assuming the Catleap does it by a fluke and wasn't designed that way on purpose.

They did 120hz with TN panels, now i'm guessing they used TN partly, or mostly, to increase the profit margin, cheaper parts and all.

But what the heck do i know...
 
VA/IPS are still too slow in terms of pixel response times to match the motion clarity of a 120hz TN. Even @60hz there is a noticeable difference. I had the fastest IPS (Asus PA238Q according to PRAD.de) and could still see a clear difference between it and my TN panel @60hz. They could still release (and will release 120hz VA soon) 120hz IPS, but just let people know that they will not be as fast as a 120hz TN (claim 6ms @120hz). I doubt any one would complain.

I used Necris' timings for OC.net and was able to achieve 96 and 100hz on my 850D. I slightly changed them because my 850D went bonkers when using the same timings. Still have to confirm if it skips frames or not but it is interesting that they work with PLS displays as well.

NCX i had thought about the whole motion clarity situation between the different panel types and without question that would be a concern for enthusiasts and possibly the MFRs.

Maybe it's easy for us armchair enthusiasts to imagine different scenarios, but i still think MFR's could have made a killing designing and advertising a "75hz" or "80hz" IPS monitor and charging an extra $50-$75 for it easily.

I'm sure the devil is in the details somewhere as usual, motion clarity/pixel response being one, but i found it to be food for thought.
 
Well I'm going to order one for a test run, if it works out well we'll order 3 more (2 for a triple monitor setup, and 1 more for a friend).

Going with the Catleap just because it looks like it'll work better in a triple LCD setup, going to see how hard the bezel is to remove. I hated my first eyefinity setup because of the giant bezels.

I just tried 82Hz and 75Hz on my S27A850D. Frames appeared to being dropped, although the monitor accepted them fine when I didn't mess with the blanking values. When I tried modified blanking values to get 85Hz under 330MHz the screen showed but there was a delay and slight blurring on the screen as if the scaler was running.
 
So the base Catleap has no scaler right? So I'd have to feed it 720p or 1440p in order to get full screen content (outside of my PC).
 
Usually anything labelled a monitor is "dummy".

Some mentioned if it you feed it less than native it just centers and scales down at 1:1 pixel mapping. Which I kind of prefer, I hate stretching images.

Will find out when I order and see mine though.
 
The catleap can't handle non-native resolutions. I tried feeding it 720p, but I get a garbled image no matter what timing parameters I try. The centering was done by that user's video card.

What happens if the game resolution is set to 1024x768, will there be black bars all around?

Yikes can't believe that I forgot about that.

Would this one work? http://www.newegg.com/Product/Product.aspx?Item=N82E16812225036

Couldn't seem to find a dual link version on monoprice.

It's not likely to work. HDMI is single-link, so I don't even know what that adapter is for.

That depends on your video card's scaling settings. You should be able to scale it while maintaining the aspect ratio, leaving black bars on the left and right.
 
I just sent Dream-Sellers my request for 3 tempered glass ACHIEVA Shimian QH270-IPSB LCD's if he can guarantee against dead pixel and dust behind the glass. Will see if this seller agrees.

Ah, good to know then. I'm only using this hooked up to a PC so no worries there.
 
I kind of use my monitors to play consoles as well. Is there a version that we know does have a scaler?
 
The 7970 should be fine, I can't see any modern video card not supporting this.

And no, you only need the north american cable. The standard cable that comes with any of your PSU's or monitors you buy here. The PSU itself that comes with the Catleap has that plug on one side.

That's the one I'm about to order, with a 5870.
 
Its showing an external power brick and close to the bottom it says its a korean plug.
 
Few questions.

Does the shimian have more inputs than the catleap? From this pic http://avlove.co.kr/ebay/20120223/qh270_ipsb/contents.jpg it seems that the shimian has component ins and hdmi (i know its the same as vga), while the shimean only has vga and dvi. Does having component in means theres a scaler in the shimeans? I know that having no scaler results in less input lag, which I do want.

Also, does the catleap have a tempered glass version? I really want the glass.

Thanks
 
The ~$400 models being sold on eBay only have dual-link DVI. The Achieva Shimian QH270-IPSTDP has more inputs, but it costs $767.90 and probably has one frame of lag.

The catleap has a tempered glass version but nobody on eBay is selling it. I don't recommend the tempered glass versions anyway because too many people have had issues with dust in the screen, which is also a common problem with the 27" iMacs. They're all glossy anyway, so I don't need one more layer between me and the image.
 
Another round of price reductions, $389 and $393 shipped for the base Catleap Q270 SE (no speakers, high refresh rate) that was originally selling for $411.

The different Shimian models have been lowered as well, they are starting at $379 shipped.

I don't imagine them going down in price much further, but these sellers are competing pretty hard for our money :cool:.
 
Thanks for the update, SJetski!

FFS, these guys must know I'm about to do my taxes (late, yeah yeah)...

NP

They just lowered the prices on the Catleap Q270 SE again btw, $379, $385 and $399 shipped.

One of the sellers has lowered the price of the Shimian to $369 shipped. <-- Note to thread-skimmers, remember the Shimian's refresh rate doesn't go as high as the Catleap's.



Edit: Dream-seller is currently listed as "out of the office", but he managed to lower his prices anyway. I wonder if there will be another round of price reductions tomorrow/monday.

Edit: Dream-seller just raised his Catleap price to $399 again, he must have been hit with PM's about price protection inquiries.

It seems though that the Catleaps have more issues with backlight problems and pixels if memory serves after reading the entire thread over there the past couple of days.

I'd grab the cheap Ahieva Shim model and enjoy 60Hz just fine myself, but everyone is different.
 
The Achieva can only go to 65hz so far without dropping frames.

I can't get any higher or the image goes corrupt. I've tried PowerStrip as well as ToastyX's CRU utility. At 71hz I got a weird vertical plaid picture. Definitely has no detectable input lag either.

And it's definitely not an over-driven panel, so no corona/halos on movement, but a little more blurring than the other 27" I've tried. Also the back-light at low brightnesses seems to have minimal flicker, and brightness control seems wide.

Mine is also a non-tempered IPSB version.

Mine arrived on Friday. It has one weird pixel an inch from the top-middle which shows black with red and green, but cyan with blue. Otherwise uniformity is decent, white point isn't bad around 6200k (but slightly greenish), and it has a huge back-light regulation.

It has some back-light bleed at the bottom.

Definitely not a mistake at $400.00 Mine also came from dream-seller but was blue saran-wrapped, not externally bubble wrapped, but the packaging was immaculate.

I totally hear you Limahl, everyone has their own list of concerns and preferences.

In addition to being more proven, if not outright the safer option, the Shimian costs less, and is still capable of a small 10% refresh rate bump. Some may laugh at that 10% but the rest of us know that a potential 10% increase in frame rate just crosses the threshold of being noticeable in games.


10e, thanks for posting your observations. The backlight bleed at the bottom you're getting may settle in and improve over time, but with your experience i'm sure you knew that already :p
 
While people with these panels are actively viewing this, what did you buy (or already have) to hook this up to a US electrical outlet? Just wondering if it doesn't matter what I buy for that stuff (since tbh I've never had to do it before)
 
You just need a standard power cable, like the one you use for your computer or any other monitor.

Honestly, there isn't a big enough sample size to make a determination.

Here's my catleap's backlight:

The bottom right is a little bit brighter, but it's fine otherwise. No edge bleeding.

I'm not an owner but i've read each post two or three times now in both threads. All you would need is a standard three prong powersupply-type cable, otherwise the included power brick does all of the voltage converting.

Edit: Toasty beat me to it.

Toasty that's some nice uniformity your Catleap has, and to think cameras exaggerate the flaws, it must look great in person.
 
Hoy crap the prices are better now.

Seller greensum's got most of them at 369-379 now.

30-40 bucks cheaper than when I paid for the Catleap SE at 413 on Thursday.

BB
 
Oh that's it? Sheesh, all the eBay descriptions had me thinking I'd need to change my outlet -_-
 
Well that's frustrating. $30 more than I paid less than a week ago. Mine got here today, will give impressions later.

Never said my memory wasn't faulty :p

There's only 29 votes on the poll atm which is far from a representative sample, esp when talking about LCD panels. For people considering a buy on these, I'd take the time to read that thread start to end to see what sorts of panels people are actually getting and the types of flaws they've found so far. The OP has a lot of the info copied into his first post, but there's plenty of other info spread out there as well.

You might get a mint panel like the OP over there did, but if you have problems, CS is half a world away and they may not be of much help, so educate yourself as best you can before you toss that $400 at them, esp if you're very picky about what your screen looks like.

Though, for $400 really, a 27" 2560x1440 IPS screen is a steal even if not "mint", esp with the lack of an AG coating on it. One guy got his in with a broken frame and still set it up and is using it I believe, he liked it that much! ;)
