Nope, not as far as I know. Even if you find a seller that will check for back bleed, who's to say his/her standards will be the same as yours? I doubt anyone is going to measure it with a spectrometer and tell you that it's within such and such a range.

They also offer a plain stand model for about the same price as the Shimian. The Catleap though? I have no idea. The price has jumped huge on those since I was shopping for mine in May.
So really... if you want to pay extra for pixel perfect from a specific seller, do it. Make your decision on price and looks. Since you said you don't care about looks, just base it on price.
Green-Sum is selling the Catleap for $330, if you're set on that model... I found the listing buried among a pile of 490-500 dollar listings.

whats the "without glass" part? whats the viewing difference w/ or w/o

yea I noticed the Catleap prices have skyrocketed since May, I wasnt sure if there was actually a reason. Yea actually went through green-sum's feedback and "view item" for ppl who had paid $300-329 and links to the $520 auction on ebay, odd

In regards to all the non "usually mentioned" brands like potania/neo or whatever, I'm guessing they use the same panels, and are just newer sellers trying to get in on this?

how bad can this backlight bleeding get, for say gaming?

oh and from what i read ppl hvaen't been to happy with Green Sum lately, hmm

My Shimian Lite came in after only 2.5 days. Talk about fast shipping. I bought mine from Red Cap who tests them out prior to shipping. There are zero dead pixels from what I can tell so far. I attached a side by side with my Asus VE278Q that I paid more money for than the Shimian. The Asus is on the right. The viewing angles and color fidelity are incredible. I calibrated the display with windows and then compared it to an icc profile I downloaded. It was quite comparable.

I'm very happy with the way all this turned out. My Asus for sale and with any luck I'll be able to recoup some of the cost. I could care less about 60hz vs 120hz. I run on a GTX 680 SC and am quite happy with playing at 60fps with vsync on.

I hate coming into a forum with no posts and asking this, but I'm at a loss.

I just had my Shimian QHD270 arrive earlier today. I'm running a new Macbook Pro-Retina, a Monoprice dual-link DVI adapter. Everything is plugged in, USB & Thunderbolt/mini display port all snug. I've tried 2 different Dual link DVI cables. Power brick is green. Checking 'Monitor' in System preferences the computer can see the QHD270, but all I'm getting from the display is a blue blinking light. From what was written earlier in the thread this means the monitor detects no signal, but as I said, the computer can see it is there. Are there drivers necessary to use the Monoprice adapter? I know with non-Apple USB-Ethernet adapters you need a driver, does the Dual-link DVI need a driver?

Thanks

In my understanding, you don't need a driver for such an adapter.
However, it is not so simple to convert DisplayPort to Dual-link DVI,
that most of those adapters including Apple's one have some issue.
Actually, I'd like to get one, and it seems that Kanex's one is better than others.

just a bump on what buying one "with out glass" refers too, are there different glass panel options on these?

Some models have the tempered glass on top of panel.
For instance, Yamakasi Precision 2703 or Achieva Shimian QH270-ISPB(or ISPI which is "inner" or "inside" version) has always tempered glass.
For some other models, it is optional.

I think I actually read somewhere that Macbook Pro Dual DVI does not work with these...not sure where I read that.

I have a 7950 video card, so which one is the best lol smile.gif
Achieva Shimian QH270-Lite for $330-360
Crossover = $390
and the Catleap for $500
Why is the Catleap $500? is it that much better, hell why is the Crossover more than the Shimian.... I remember not to long ago they were a bit cheaper, or i'm insane possibly
Also see: Potalion - $370.00, Inch Matrix Neo, PCBAnK I never see anyone talk about these brands, i'm sure they do but not that i've read

pretty sure people in this thread have gotten the PCBanK and the Potalion - they are all basically the same. I cant comment on the price swings but if i had to guess the catleap is more expensive because its a better know name now because of threads like this one.

I have 2 Shimian QH270s, running off a 7950, and i play GW2. game looks beautiful. I got them from TA_Planet, I did not pay for perfect pixel, but i got perfect pixel. 1 monitor has a good amount of light bleed in the bottom right corner and the other one has a small amount of top bezel sag, but TBH those issues are so minor in the grand scheme of things i don't care.

@Sibuna - I noticed you purchased both of your Shimian QH270s from ta_planet. I am about to buy 4 of these from him and he said that he included a 110~240V free voltage adapter included. As well as the US plug adapter. Did you get this free voltage adapter from ta_planet when you ordered and if you did, does it work like it should? Just checking to make sure I don't need to buy some other voltage adapter for the monitors to work properly and so it doesn't overheat and blow up. If you could get back to me really soon that would be great. I tried to send you another PM but it says I maxed out my 2 PM's per day.

Thanks so much for your help.

Michael
