YAMAKASI Q270 JUPITER LED 27" AH-VA WQHD 2560x1440 DP HDMI DVI D-SUB Computer Monitor

I do most of my production work on an iMac27 (most recently of the 5k retina variety), but also need a functional PC on occasion. For the past several years, the display I used for the desktop PC was an HP Pavilion 27xi, which I wasn't fond of. The 27xi was well made, but I simply did not consider 1920 x 1080 1080p resolution adequate for office and coding work on such a large screen. I'd been meaning to get a full 4k screen for the PC desktop, but they are still a bit too costly for my taste. So when Amazon sent an email teaser for the Yamakasi Q270 27" screen for a very reasonable price and free shipping, I bit. Not without first reading a lot of the reviews here on the display (thanks, Megarat!!), so I more or less knew what to expect.The screen arrived within just a few days, from Korea! It came in its box, with an extra layer of thin bubble wrap around it. No damage.What I like: It's light and handy for such a large display, I LOVE the matte display surface like iMacs used to have). Colors are deep and rich, the screen is more than bright enough for office work. The viewing angle is essentially perfect from any angle, without any color or contrast shifts.What I didn't like so much are a few things I already knew about from the reviews. The stand may look good, but it's too lightweight of a solution for such a large display. The nice manual is entirely in Korean, and the default menu system, too (it's simple enough to figure out how to set the language to English, though). And whatever one might want to know is on the Yamakasi Catleap Monitor Club forum anyway.YAMAKASI Q270 JUPITER LED 27" AH-VA WQHD 2560x1440 DP HDMI DVI D-SUB Computer MonitorDid I get it to work in full 2560 x 1440 mode on my basic Dell Vostro 3900 with an i5-4460 Haswell chip? The Dell came with VGA and DVI ports, and first I tried the DVI port with the DV-D cable that came with the Yamakasi screen. With that I only got 1920 x 1080. So I put the inexpensive AMD Radeon R7 200 Series card I had used in my old HP desktop in the Dell, and connected via HDMI. Ta-Da! 2560 x 1440 resolution!To my eye, the switch from 1920 x 1080 on my old HP Pavilion 27xi to 2560 x 1440 on the Yamakasi is tremendous, and I am very happy with my purchase.

I've been using a Princeton 24" 1920x1200 display (Princeton Vl2418w 24" Wide Screen Dual Input Flat Panel LCD Monitor) for many years now, and have been feeling the constraint of the limited real estate. This is the display for a workstation in my home, serving as the front-end for four different computers through a KVM switch. It gets used for household tasks, as well as my work (both day-job and consulting) in the field of bioinformatics and data analysis. This wasn't an essential purchase, as the Princeton has been working fine, so it took a while for me to build up the nerve to upgrade. I wanted at least 2560x1440, and ideally 2560x1600. I didn't want it to be larger than 30", and weight was an issue, as I wanted to mount this monitor on a VESA wall-mount arm (LX Wall Mount LCD Arm) that has a 25-pound limit. After some research, this monitor floated to the top of the shortlist and I gave it a go.And it's perfect. I love it. I've had it for a month, and it has exceeded all of my expectations. Zero dead pixels. Essentially no backlight bleed. While I'm not a "serious" gamer, I do some recreational gaming, and the refresh rate is totally fine. No issues at all. Excellent contrast, excellent blacks, good colors. And the resolution is great, especially for a monitor of this size. It looks totally lovely. Now that I've got this baby installed, I'm now of the opinion that 2560x1600 would be overkill (though my opinion may change in a few years).If I were being truly objective, I would dock my rating by a star, maybe two, because this monitor wasn't turnkey: it requires some DIY effort in order to work satisfactorily. I knew this going in, so there were no ugly surprises on my end. But I suspect that some people (and perhaps the majority of the casual computer-buying public) would find this monitor to be completely unacceptable as-is.And this is because of its suboptimal, integrated stand, which is the biggest caveat I can offer about this monitor: its stand sucks rocks. It sucks rocks so hard, it turns them into diamonds. I used this monitor with its original stand for about a day or so (to make sure that the monitor worked before I broke out the tool kit), and I can add to the chorus: its built-in stand is garbage. In my case, it had two critical issues: (1) it tilted the monitor to one side by about five to ten degrees; that is, from the front, looking at the screen, the monitor was noticeably lower on the right side than the left, and it couldn't be adjusted without shimming the base. (2) It was ultra-sensitive to vibrations and wobbled at the slightest provocation. If your computer keyboard shares the same surface as the monitor stand, a decisive hit of the return key or a frustrated tapping of the backspace key would make it wobble.Luckily, the stand can be removed, and the monitor has a 3" VESA mount on the back (yay!). Unluckily, to remove the stand and get at the mount, you need to spend about an hour painstakingly taking the monitor apart (boo!). You can find instructions online (Amazon discourages external URLs in product reviews, so search for the "Yamakasi Catleap Monitor Club" with your favorite search engine), and I recommend checking out the procedure before purchasing it. No soldering is involved -- you'll only need some screwdrivers and nerves of steel -- but still, the procedure isn't for the faint of heart, so if you're not experienced with dismantling electronics, find a friend who is. Of course, if you remove this monitor's stand, you'll need to replace it with another one, such as: VIVO Single LCD Monitor Desk Stand Fully Adjustable/Tilt for 1 Screen up to 27" (STAND-V001F) . (And additionally, opening it up will void its warranty, so take a moment (or a day) to confirm that it works as expected before removing that first screw.)I'm reasonably experienced at this sort of thing, and it took me about an hour of careful surgery to get the stand removed and have everything buttoned back up. Now I have the display connected to the wall mount and I can't imagine anything better -- for my own needs, at least. There might be equivalent monitors out there, at an equivalent price point, that don't require as much effort to get them VESA-mounted, but I wasn't able to find one. I also get a minor thrill out of doing some custom work on something in order to get it exactly how I want it, so it's win-win. I'm delighted.(For some other pointers, the monitor's settings menu is in Korean by default, so if that's an issue for you, you'll need to change the language in the settings. Unfortunately, it's difficult to change the menu's language if you can't read the menu options to begin with. So try this: press the "M" button, then press the down-arrow button until you get to the "OSD" icon. Press "M" again. "Language" is the top option and should be selected, so press "M" again. This should give you a list of language options; highlight your preferred language with the arrow buttons and select it with the "M" button. If only we all used Esperanto as a standard global language, but no one ever listens ...)I also feel compelled to mention another minor nuisance: the front bezel is really, really smooth and shiny -- imagine the shoes of an ROTC cadet on inspection day. It's shiny enough that I can see the reflections of my fingers typing, which can be distracting. It also soaks up fingerprints better than sunglasses. I probably won't care about this in a month or so (update from the future: it doesn't bug me anymore), but for now, a big glaring fingerprint on the bezel of my shiny new monitor is vexing. It's the same with dust. A tiny dust particle sticks out against that piano-black background like a low-magnitude star. I guess this means I would prefer a matte texture, but it still looks lovelyAnd lastly, I am compelled to mention that this monitor has a greater resolution than what is regarded as "standard technology", so it will require a DVI dual-link or display port connection if you want to use its maximum resolution. Regular (single-link) DVI or HDMI will only work up to 1920x1200. This was an ugly realization for me, as my KVM switch only supports single-link DVI, so a new KVM switch is in my future, and thus getting a higher resolution display turned out to be a more expensive proposition than I had originally expected. But that's not this monitor's fault. Those people with only a single computer can use the supplied dual-link DVI cable and probably won't even notice the difference. But if you're using HDMI, or if your computer only supports single-link DVI, then you'll only get 1920x1080, scaled up to the full display.

Performs as advertised, VERY difficult to get to the Vesa mount to use it in portrait mode. Documentation in English is nonexistent. Onscreen menus make me feel like an archeologist missing my Rosetta stone.

What everyone says about the stand is true, but I have the monitor placed on a desk made from an old door, so if your table it solid, the stand will suffice. The monitor itself is more than adequate, given the price. The on screen controls are in Korean, but easy to figure out. The controls are minimal, but they do make a difference. All in all this is not a Thunderbolt Display, of course, but at the price I have no complaints. Unlike the Apple monitor, this monitor lacks the glass overlay, and thus is bright yet doesn't suffer from issues like reflection that the Apple monitor does. It shipped ultrafast, there are no dead pixels, and ultimately I can do my work and use the savings elsewhere. I would definitely recommend this to folks who are aware of some of the build issues that others have already spoken of, and keep in mind that you will need to purchase a display port/mini display port cable if you are planning to use with a Macbook Pro.Also, regarding the Macbook Pro (I have a mid-2014 15") I have no issues with putting it to sleep and the taking it out of sleep [as I did with a similar Shimian 2.5k monitor that uses the same panel]. All in all this is a solid solution for me and others who may be looking for a similar setup
