Depending on how many people want what, maybe you would be able to bring some IPSB and some IPSM, depending on the minimum quantity that your supplier wants.

I'll be ordering from the manufacturer. MOQ is 100, so yes, I'll be taking a relatively significant risk. I'd like to minimize it as much as possible by bringing in a product people want.

It appears their product line isn't very well described, as the specsheets I got from the manufacturer do not have some of the models mentioned, but for now, I'll be looking between the two,
QH270-IPSBS
QH270-IPSMS

Similar specs, but the BS only has "DVI dual Only", where the MS has "DVI (dual) / RGB / HDMI / Audioin/out / MHL(next version)" Although, I assume no one will want the audio output from these monitors - why have such a pricey monitor with low end speakers, right? (it may just be the picky audiophile in me, though. what do you guys think?).

Oddly enough both panel types are described as,
"S-IPS / with white LED backlightunit / glare / black coating LGD LM270WQ1"
I'll have to figure out (well, and wait for their second response), to my other questions.

Oh, also, I assume the MS (50$ more expensive, too) panel is the one with the OSD, as it has dynamic contrast capability. a question has been sent about input lag with that one, too.

I'd assume the QH270-IPSBS would definitely be the most popular, considering it's the cheapest and how many people are fine with a pretty bare-bones monitor as long as it's a 2560x1440 glossy IPS, plus the benefit of no scaler. Also, the fact that it doesn't have tempered glass like the IPSB reduces the chance of issues, since 2 people over at overclock.net seem to have dust behind the glass in theirs.
 
If I end up with dust I'll probably open mine and clean it, so expect teardown pics if that happens.

Are you planning on selling these on ebay or in some storefront?
 
Couldn't wait any longer. Just ordered the speakerless Catleap from DreamSeller, 413.90

Once it gets here, I get to upgrade my 5770 - to a 7850, once AMD releases them this month.

What power adapter are you all going to use?


I need to pick one up, but from the images of the ones on amazon it looks like most are designed for a US plug input, with multiple outputs for other countries.


http://www.amazon.com/NETHERLANDS-T...2?s=electronics&ie=UTF8&qid=1330648232&sr=1-2



they may also allow other country plug inputs to a US outlet, but they damn sure did not make that clear from the images.

I thought the plug end tips for the korean monitor were different than the US plugs, you saying it comes with a standard us plug that can be inserted into any standard US wall socket?

The power brick has a standard pc cord connector. Just use a spare cord you probably have laying around.
 
might have found another korean company that sells the same panel. Something tells me they probably come from the same manufacturer with just a different exterior, b/c this one even has the crappy rear speakers too. It might be worth looking into, or possibly cheaper http://english.gmarket.co.kr/challenge/neo_goods/goods.asp?goodscode=202737383 if you scroll down to specifications it lists lg ips display and 6ms etc.

here is the company website (I think). http://www.preegia.com/bbs/board.php?bo_table=04_2&wr_id=40

Hi, looked at this forum on occasion for years, anyways does anyone like that 10E chap etc know if these are likely to be factory calibrated?

TFTcentral said the Hazro 27 "C" model was, and thats pretty much the same screen as this I think.

Im not a professional user , and have not used a calibrator, but I buy IPS mainly for nice accurate natural colours and the Dell U2412M disappoints.

They probably aren't. We're getting the most basic models with only one input, no scaler, no OSD, etc. so I don't see why the manufacturers would waste time and money calibrating these. The more expensive 10 bit monitors might be calibrated, but we would need someone to read the Korean reviews of those to be sure.

The Crossover 27q LED looks very interesting with its aluminium body and sturdy stand with good ergonomic functions such as swivel, tilt, pivot and height adjustment.

Indeed, but it only has a single DVI input, and the build quality of the back looks a bit...shoddy.

on a side note, calibrators aren't too expensive, if you have high end IPS monitors it makes sense to pick one up.

yeah gmarket is just for reference :)
I agree, crossover looks to have the best usability, since it has tilt pivot height adjustment etc.

the presentation images look pretty similar to the other companies. I wonder if the same design person made them up for all of them :p

found a review for the Crossover 27q http://www.playwares.com/xe/maingame/19660693

they also reviewed the Catleap q270 http://www.playwares.com/xe/21449157 (8.0 score )

and Achieva qh270 http://www.playwares.com/xe/maingame/20925987 (8.0 score )

another review, different company yet the same panel "3VIEW PB2700" http://www.playwares.com/xe/20531033 (for some reason the panel scored slightly higher than the other 3 above. not sure why, since i cant read any of it)

finally a FIFTH company with the same lcd panel: "first" fsm-270hv http://www.preegia.com/bbs/board.php?bo_table=04_2&wr_id=40

things are getting crazy over on the overclock forums, some people are claiming they can increase the refresh rate on the catleaps to 97Hz... craziness, did not even think that was possible with any current ips displays, and still not convinced it's real.

craziness starts here:

I like the style of the Catleap better myself but fewer people seem to have tried one out. The whole 97Hz thing seems a bit......strange to say the least.
 
I doubt that it does not skip frames @97hz. I will believe anything under 76hz which would be amazing.

I wonder if the high refresh rates will work on the S27A850D...
 
I have documentation from the manufacturer:

2560x1440@60Hz
Horizontal Freq: 88.8 Khz
Vertical Freq: 60.01 Hz

1920x1200@60Hz
Horizontal Freq: 74.10 Khz
Vertical Freq: 59.99 Hz

Might apply but I'm unsure what's going on with his system.

I will verify when I get mine. It's not outside the realm of possibility, but it's certainly unexpected.
 
I should really stop checking this thread and the one over at overclocker.net. My tax refund just came back, too....MUST RESIST....
 
27" IPS panel for this kind of $$ is almost too good to be true. If someone gets a hold of a bunch of these stateside to sell i'd be all over it.

Soo many brands. Just need to figure out the best way to order it.

I fully agree, i highly highly doubt it gets anywhere near 97hz without dropping frames. I'm thinking bandwidth and mainboard limitations, panel refresh etc etc, the deck is stacked against it.


Edit: take my assumptions with a grain of salt and check out the interesting clues ToastyX posted below.

Actually, the deck is stacked in favor in several ways. This particular panel is directly driven internally by a DisplayPort signal, not LVDS like most other panels. These monitors also have no OSD or scaler, so it's likely the controller just does a straight in-place conversion from dual-link DVI to DisplayPort because that would be the cheapest implementation. This means the monitor might accept anything you give it and send it to the panel. If that's the case, dual-link DVI and DisplayPort both have the bandwidth to pull this off. The limit that person ran into was actually the RAMDAC limit of the video card, which limits the pixel clock to less than 400 MHz. All of this gives me hope that this is real. I will do objective tests when I get mine and post the evidence if it works.
 
HDCP Support at all? So because this doesn't have a scaler, I wouldn't be able to play a game in 1080p or an older game in a lower resolution other than the 1440p one? Is this correct?

Your video card would do the scaling based on the driver settings you pick.
 
Got my IPSBS. Doesn't seem to like anything over 65hz though, and ToastyX's utility doesn't seem to want to work at all. Odd.

Either way I couldn't be happier, no dead pixels, contrast is apparently great, viewing angles great, only issue is the stand which is a bit flimsy and there seems to be a bit of horizontal color temperature difference from top to bottom. Not a huge deal though.

Couldn't be more satisfied for $400 :)

Pics? :D
 
My catleap came in this morning.

First impressions:

* Package was bubblewrapped like others have mentioned.
* The stand is a bit wobbly, and the monitor seems to lean a little bit to the right.
* It does have VESA mounting holes in the back, but it's covered by that gray plastic which you have to break off to access them. The gray plastic was already breaking off out of the box, so I might as well remove it since it serves no purpose. The rest of the monitor is intact.
* It's glossy, not tempered glass.
* 1 dead pixel in the bottom left, 1 speck of dust behind the panel in the bottom right. This is not the same as the dust that people are getting with the tempered glass versions. This is behind the panel and leaves a faint gray shadow. I've encountered this before with other LG IPS panels, so it's not specific to these monitors. The dead pixel and dust are in corners where I will almost never see them, so I'm not bummed out about it.
* 5 buttons: power, brightness up/down, volume up/down, although this one doesn't have audio input, so the volume buttons are useless. For some reason they included an audio cable anyway.
* The backlight doesn't seem to flicker strongly at a lower brightness.
* It's dead silent, even at a lower brightness. If you hate buzzy monitors, this monitor is for you.
* These monitors need calibration to look their best. I'm used to calibrated monitors, so the colors out of the box seem a little off, but not terrible.
* I will check for backlight bleeding when it gets dark.
* Black seems to glow more when looking left to right than right to left, so the bottom right corner will appear to have more glow.
* There's no lag as far as I can tell, and there shouldn't be considering there's no scaler or OSD.
* The pixel response times aren't the best. It's definitely not 6 ms. It doesn't have overdrive. It's about the same as the NEC EA231WMi, which is rated at 14 ms. It's also worse when first turning on the monitor, but gets better after warming up.
* I can confirm that it actually does accept higher refresh rates without skipping frames, but my video card (ATI 5670) won't let me exceed the 330 MHz pixel clock boundary, so I can't get 97 Hz. The best I can get is 85 Hz with these timing parameters:

catleap-detailed-85hz.png


I will do more in-depth testing later along with pictures.

85hz!

@ToastyX can you post your before/after calibration results and an image of the backlight?

Seems like these are the montior to buy @400$. if if the colour presets are not fantastic it is still cheaper to get one of these and an excellent and a colourimeter like the i1 display pro than to buy any other 27" 1440p display.
 
Pretty sure we're only going to see 85hz on the Catleap's. My Shimian doesn't seem to want to touch anything higher than 65hz and even then sometimes it just decides not to display it.

edit; could be my video card though? no idea really, it's an old 8800gtx.

I'll get around to it. I haven't even calibrated it yet.



85 Hz proof pics (catleap):

I set the camera's shutter speed to 1/10th of a second and took pictures at 60 Hz and 85 Hz.

I used Refresh Rate Multitool, which is a program that synchronizes with the monitor's refresh rate and draws a bar moving from left to right once per frame.

60 Hz:
catleap-bars-60hz.jpg


85 Hz:
catleap-bars-85hz.jpg


Notice how more bars are drawn in the same amount of time at 85 Hz, and no bars are skipped.



I also did the old mouse cursor test:

60 Hz:
catleap-mouse-60hz.jpg


85 Hz:
catleap-mouse-85hz.jpg


Notice how more cursors are drawn in the same amount of time with less spacing between each cursor. The movement is perfectly smooth with no skipped frames.

Note: If you do the cursor test, make sure to use a 1000 Hz or 500 Hz mouse, otherwise it may look like it's skipping due to mismatched rates.

For reference, this is how skipped frames look like:

mouse-ds.jpg




This is the real deal. It can actually do higher refresh rates properly, and NVIDIA users might be able to get more than 85 Hz if the pixel clock is not limited to 330 MHz.

The 97 Hz limit seems to be due to the pixel clock hitting the DAC limit of 400 MHz. I bet it could hit 100 Hz if the timing parameters were bumped down a bit, but I don't have an NVIDIA card to test this with.
 
Got my Catleap in today too! After fooling around with it for an hour and half, ToastyX's review seems to be pretty spot on.

-The package was wrapped in bubble wrap and there was no damage to the monitor.

-The stand is a bit crap. It's a little wobbly and the monitor leaned to the right. Removing the ring of plastic on the bottom of the stand that allows the monitor to swivel helped a little with the lean, but my more permanent solution was to fold an envelope in half and stick it under the stand. Not pretty, but my desk is usually covered in papers and crap, so it blends in. :p
I'm glad there's a VESA mount hidden on this thing, because I'm going to look into getting a better stand.

-The cables the come with the monitor are fairly short. This isn't such a big deal with the power adapter, because you can always get a longer cord. The DVI-D cable is 4 to 5 feet long, which might be too short for some.

-No dead pixels or dust stuck in between layers for me.

-The screen is very glossy, so I wouldn't use this monitor at all if there's a strong source of light behind you.

-Backlight bleed is pretty bad in the lower right corner of the screen. Here's a pic at max brightness and one at minimum. Both pictures were taken with my Galaxy Note in a not-quite-dark room, but they give you an idea of the problem. I currently have the brightness set somewhere in the middle - it's hard to tell, because there's no OSD. Max brightness is good for burning out your retinas. :D

-I haven't messed with any games yet, but the Lagom pixel response test wasn't very impressive. We'll see how it affects things, since I'm coming from a quick-ish TN.

-My Catleap accepts higher refresh rates, but only up to 81 Hz. If I input anything higher, Windows defaults back to 60 Hz.

Overall, I'm pretty happy with it! It's not perfect, but it's also much cheaper than the ZR30W that I was looking at getting. I'll keep an eye on this thread, so feel free to ask questions.
