View Full Version : Anyone using those ~$350 27" 2560x1440 S-IPS screens with their Macbook Air?

I've seen a lot of positive reports about Korean 27" S-IPS monitors on Ebay. They use similar panels as the Apple Thunderbolt screen.

The cheapest versions only have dual link DVI. I guess this won't work with the MBA unless you buy an active dual link DVI converter.

There is a version with HDMI input. Would this work with MBA mDP to HDMI? 2560x1440

The problem with those panels is that if you get bad pixels, just to ship back is so costly that it won't make that much sense to be honest...
I don't do that much design work, so I'm using 27" TN panel that I got awfully cheap...

They sell models with perfect pixels too. They're feedback is positive so I'm willing to take a risk.

I have one en route. Should arrive by Monday. I'll report back, but yes, feedback has been very positive.

Here's an all encompassing thread detailing the experience of MANY who've went the Korean route.

Don't forget to factor in the pricey $65 Dual-Link DVI adapter though.

If you have a Microcenter nearby they're selling the Korean 27"s at a reasonable markup. That way you have an easy return in case of any problem.

I think the version with HDMI input should work without the pricey adapter.

In Europe these dual link adapters costs about ~100 eur. So buying the monitor with HDMI should be cheaper.

You would be limited to only 1920x1200 through HDMI though.

Yes but the way apple has HDMI implement currently there isn't anyway to get anything higher then 1920x1200. Also since we are talking about Macbook Air's you would have to use a mini displayport to HDMI adapter which are limited to that resolution, are two similar but different technologies. There are a lot of factors as to why it is limited.

Besides we are just talking about these monitors with the Macbook Air specifically which will be limited to 1920x1200. Just look at the Mac Mini and the new rMBP the HDMI ports on them are also limited to that resolution. If they are then I can bet that the MBA would be to.

Do you mean you personally tried a Macbook Air 2011 (or later) with a 2560x1440 monitor through mDP to HDMI?

Ok. Well... Having had a 2011 27'' iMac and being somewhat color conscious as an amateur photographer I can say that with the exception of the bezel, the PQ is pretty damn solid. The colors and rich and images sharp

BUT...

I rolled the dice and went for the tempered glass version - which the sellers warn run the risk of shipping with dust behind the glass.

Well, there wasn't any dust.

BUT...

There is what looks like a god damn crumb of Styrofoam about a centimeter off the bottom edge on the right corner... behind the glass. F Me.

AND...

If you jack the brightness up and toss on a pure black image you'll definitely notice some bleed in the corners. You'll see it clearly in the image below but it's being grossly exacerbated by the camera sensor.

BUT...

for $360 (Monitor plus Dual-link DVI from Monoprice) I'm still satisfied. Very satisfied.

How shoddily are those things being put together if the seller themselves warn of dust in the screen? I do wonder about their longevity.

I am still considering whether to pull the trigger or not. Basically, these cheaper Korean brands (Shimian, Yamakasi, Achieva, CrossOver) all run the LG IPS panels which Apple uses for their Cinema screens.

There multiple variations of each brand (some more than others) and comes with different options (built-in speakers, HDMI stero, tempered glass, etc).

Unfortunately, one of the biggest drawbacks is their main use of DL-DVI. If you search MBA or MBP with any of these monitors, you'll find a few articles stating u need certain DL-DVI, Thunderbolt, MiniDisplay hardware to make it work.

You can't find any other monitor of that size with that sort of resolution w/o spending a fortune.

As long as you take the $60+ USB/MDP adapter into consideration when purchasing, you shouldn't be disappointed. It's simply not plausible to get the max resolution (with a MBA) w/o one of those "pricey" adapters.

If you want a similar monitor for more money and one that doesn't require one of those adapters, you left with an option such as this one which has a DP connection:

I bought the Shimian in April and it has been well worth it. I'm still really impressed with it. I wouldn't buy the tempered glass version though because it's just one more thing to potentially have a problem. The monitor worked perfectly with my 08 MBP but I didn't need any adapters for it. I plan to pickup an Air next week when I get back from vacation so I can't speak about that, but like others said you would need the DL-DVI adapter and not HDMI.

Being a gamer, I'm glad most of these monitors are pretty bare bones without a scaler and OSD, but having only one output is a nuisance sometimes. The only problems mine has are 1 stuck pixel in the upper left I never notice, a slight tilt to the left which was corrected by a folded piece of paper, and it does buzz at full brightness on huge white images/websites (doesn't bother me since I always have music or a fan going). Despite this, I think it's a great value for the money and I'd order another one in a heartbeat.

Surprised there isn't more talk about these on here. My buddy just informed me on these and he bought two of these from Green-Sum. They come with HDMI, speakers and US power plug since all the cheaper ones only have the Korean plug on them.

I can't wait to check them out. I'd love two of them myself to replace my dual 23" ACDs.

Does anyone know if they are glossy or matte?

I purchased this one:

It arrived in 3 days! I'm extremely pleased with the screen quality and build. Many people have complained about the stand, but I see nothing wrong with it as it does what it is supposed to. Although I ordered the perfect pixel version, there were still a good amount of dead pixels (10-20). However, the pixels are so small that they are almost impossible to see. Had I known that the advertised "perfect pixel" ones also come with dead pixels, I would have just bought the normal version and saved some money. Per the seller's policy, I'm going to try to get a partial refund for the monitor due to the # of bad pixels. Here is a link comparing the different versions of these displays:

It should be able to run it. I can't speak from experience how well it runs (I have a 1080p monitor, not 1440p), but it definitely is capable.

Yes, a 2012 Air will run a 2560 x 1440 27" monitor. I have used that arrangement with no problems for playing hi-res, hi bitrate movies.

Probably not so good for the really heavy duty video work, like high end gaming.

I'm not sure I understand what the appeal of these crappy monitors is. I got my Dell 2713HM which works amazing with the air for $549 on sale.
Even when not on Sale they are in the lower $600 range. Why buy a crappy one for $100 less ? :confused:

Wait Till the Dell goes on sale again.

I bought my pixel-perfect Korean monitor for $290, which is a lot less than the Dell (and has no dead pixels nor any other issues). If it was a $100 difference, I would have went with the Dell though for peace of mind.

they're not "crappy" you're comparing A+ panel to a A- panel far from crappy

Does Dell still use that crappy coating on their monitors that give a moire or shimmer effect? It was a turn off on their 24/30" monitors several years ago. These Korean monitors at least don't have that coating.

You seem to be forgetting when this thread was created. The appeal of these monitors is that you can get a good display with an A- panel for a lot less than the competition. The main interest in these was during the spring/summer of 2012, and back then the equivalent Dell was not in the lower $600 range not to mention the input lag which was off putting for gaming. One of the cheapest 1440p monitors you could buy in the US was the HP ZR2740w which at that time was around $700 but many didn't care for the AG coating on it as well as the Dell. I prefer a glossy display and still consider the Shimian a great buy for the $330 I paid in April of last year. Even now Monoprice sells one of these Korean monitors at $390 which is a great price compared to your $550 Dell.

Not to mention that the monoprice 27" has DVI and VGA only (which would require an expensive adapter) and the dell has DP and HDMI in addition to DVI & VGA.

Personally, I'd rather spend a little bit extra and get the Dell.

Purchased on Ebay from green-sum on December 15, and got it 3 days later (Canada) on December 18. I was really impressed by that - 1 day sooner then the earliest expected date (Dec 19-31 was the "range" given). I decided to purchase the QNIX QX2710 LED EvolutionⅡ 27" 2560x1440 monitor after much research (well, mainly decided to purchase one of the monitors from Korea in general - then narrowed it down to that). For just over $300 including shipping and a wave of great reviews there was no choice between spending over 2x to almost 3x for a major brand for this high resolution monitor.

I chose the matte screen (I was not even aware of tempered glass screens until I researched the Korean monitors) and my "version" of this monitor in general is bare bones (just a dual link DVI-D connection at the back & power & audio). It arrived in several layers of bubble wrap neatly taped over the main cardboard box which fits all the contents. After taking the bubble wrap sheets off, there was no signs of any marks or damage on the box itself - it was well protected.

Skipping to the unpacking, everything was as it should be... had all the contents (and a very handy adapter for converting the A/C male prongs to the North American standard. That saved the nuisance for having to source one out... but you can plug in your own standard power cable into the small transformer anyway. The screen itself was well protected with a heavy gauge plastic sheet covering it, and the bezels covered with easy peel-off wrapping. I was very impressed with the professional packaging - even slightly superior to the major brands in stores. The entire monitor was also additionally inside a clear plastic bag which was made to fit. I should also mention the screen rested snugly in styrofoam grips inside the box - I suppose that is expected however.

Everything was set up without a hitch and I was treated with a gorgeous 27" 2560x1440 display for the first time... it was just as good as I imagined it to be. I had it placed beside my 24" Samsung monitor I purchased the year before - there was hardly any difference in the display. I did slightly increase the brightness & gamma setting in my graphics card to match the Samsung exactly... whether it was "better" or "worse" is hard to say objectively... but I did it anyway for no particular practical reason. It was neat just to see that I could match it as I never have adjusted any part of my graphics/monitors before.

No dead pixels, No backlight bleed (well nothing that I could honestly point out anyway...) On the subject of dead pixels, due to increased DPI I would say that even if there were a few dead pixels it would have hardly mattered at all. It would be nearly undetectable even with solid colours (and I did have to go up quite close when I did my visual inspection to really check for any dead pixels). I would not have even cared if there were a few - under normal usage it would be invisible) I admit, I was very happy that were were none as a matter of principle.

The overall finish was great (the stand/monitor as a whole) and the quality is top grade. Yes, the stand support is *slightly* more flimsy then some major brands but not enough to matter at the least. It doesn't flex like a spring as one Phillips monitor stand did in a store. Compared to my 24" Samsung, the monitor is "thicker" by about 2.5x. That is not because it is thick by any means, but just because the Samsung is extremely thin... again this doesn't matter in the least - it actually looks really good from the side and back to be honest - a bit better then the pictures online portrayed it to be. AND it is still slim for screen standards (about 1").

I was considerably more impressed then expected (I was expected to be content)... to top if off the labels for the backlight brightness / volume / and power buttons were actually in English! (Which looking now you can just tell looking at the online pictures enlarged) This was good because they are visible from the front and I won't lie - labeling from an unknown language is annoying if visible. That was a really nice touch for me.

The way I see it, I saved myself around $500 to have a 2560x1440 monitor without an HDMI connection. (NOTE: you actually can get a version with extended inputs such as HDMI for a premium) I would not have gotten a monitor with this high resolution due to the exorbitantly high price. When I stumbled on the Korean market for these near the end of my research it provided a faint hope I might actually have one in reach - at least anytime soon. That truly did come to be and again (forgive the sentiments) I am almost blown away how well everything turned out. Excellent shipping (it was DHL which does seem to have overall negative reviews), excellent quality, no hassle, and beautiful price.

2560x1440 is a blessing for certain things where you need/benefit from a lot of real estate, heck I was not aware of anything past 1920x1080p until recent months. The text and everything is a bit smaller because of the increased DPI, but I don't see this as a disability - its all still very legible. I am off to give a 5 star rating to the seller on Ebay now and I thank everyone (in other forums as well) for giving great insight to the Korean market for monitors.

On a final note, there is one problem with this monitor... I almost want to get another one! (Have to try and suppress the thought... 1920x1080 is plenty for the use on my 2nd computer) We'll see in a few months. Then again that is the computer I play games on (although infrequent)... might not know what I'm missing.

I'll add in this last thing... at 27" (sitting from typical distances of computer screens) that is about as close to the largest size screen without needing to move your head around to look at all sides of the screen... and at 2560x1440 that is just about the limit of reasonable viewing size... quite the perfect/ultimate combination.

OVERALL RATING OF THIS MONITOR: 9/10
OVERALL RATING FACTORING IN RELATIVE PRICE: 10/10
