3.0 out of 5 stars Gorgeous display, but too small to use without scaling.
Reviewed in the United States 🇺🇸 on October 22, 2015
As someone with a multi-monitor setup at work, I like having lots of desktop space. While some people purchase 4K monitors and then depend on scaling to keep things from being too small, my intent was to make use of all 3840x2160 pixels with no scaling whatsoever.

First impression is that this monitor is huge! Coming from a 24" monitor, this is a substantial increase in size, but that's a good thing. If you want a smaller monitor, buy a smaller monitor. The shock of the larger size wears off after a while, so don't let that aspect intimidate you.

To drive such a high resolution monitor, you're going to need a decent video card. I chose an ASUS STRIX 750ti for its ability to support 3840x2160 via DisplayPort and that it wouldn't run its fans unless the card was stressed (such as when playing games). I want as quiet an environment as possible, and this card served that need. The only thing that I wished it had was an HDMI 2.0 connection for future compatibility with other 4K displays that might not have a DisplayPort connection (such as a 4K TV), but in this situation, the monitor and the video card matched up well, and the price was good.

Even with a 32" monitor, I was a little concerned going in that it would be too small for comfort to use without scaling. By comparison, a 24" 1920x1200 monitor is approximately 96 dpi, whereas this monitor is approximately 140 dpi. Without scaling, that means that everything is going to be about 50% smaller.

Everything went very smoothly upon installation, and Windows 8.1 detected the high resolution of the monitor and automatically set it to scale so that dialogs and programs weren't too small to see decently. Unfortunately, this caused text to be slightly blurry, and no adjustment of the scaling settings could get the sharpness that I'm accustomed to in non-scaled displays. Since I wanted the extra desktop real estate, I set the display to not scale, but that reduced the size of programs and dialogs to a physical size that made it difficult to see things comfortably. It did make the text very sharp, and I really wanted this to work out, so I spent a couple of weeks trying to come up with a scenario that I would be happy with.

To see an illustration of the difference between scaled and non-scaled, I have attached screen captures of Adobe Dreamweaver in both modes. The non-scaled image is very sharp, while the scaled image has a slight blur to everything that can be tiring when viewing text for many hours a day.

That aside, once you see the gorgeous images that this monitor is capable of, you may not want to use a lesser monitor. Watching 4K videos on YouTube (esp. those in the Jacob + Katie Schwarz channel) will assure you that this is a monitor you'll want to keep unless something gets in your way. Unfortunately, the scaling issue as well as the small size of non-scaled content was a big negative for me.

The second negative came from the monitor itself. Unfortunately, my monitor had a buzzing sound emanating from around the power plug connection. In a busy office environment it may not have been noticeable, but in my quiet office, it was annoying. Given that I bought the monitor from Amazon Warehouse Deals at a substantial discount off the list price of a new monitor, I really wanted it to work out, so I tried to see if I could deal with it. Even after a couple of weeks, I was never able to get over it, and while I could have tried to get a replacement, I decided that the issue that I had with the size of the display in the non-scaled mode was another negative that I couldn't overcome.

The buzzing problem is a risk you take when buying something that is not new. Looking at many reviews for this monitor, it appears to be an isolated issue and not a widespread issue. Kudos to Amazon for its great return policy.

This experience showed me the benefits of having a 4K monitor, though, and I think I'm hooked. I just know, that for my situation, I need to have a larger monitor so that the dpi is less than 140 so I don't need glasses just to see things comfortably. That means that something in the 40" range would probably work quite well, but there is only one monitor available domestically that is 40" that is specifically intended to be used as a monitor (the Philips BDM4065UC). The reviews are a little questionable on that unit, and the only other options are monitors sourced directly from South Korea, so I'm looking at 4K TV's that can do 3840x2160 at 60Hz and 4:4:4 chroma, which is a rabbit hole all in its own. I keep hoping that more manufacturers will release 40-43" monitors in the meantime, but it's been a couple of months, and nothing yet.

If you can deal with the slight blurriness of the display when being scaled (or find a setting that suits you that I couldn't), or you have very good eyesight to see very small (but sharp) text, this is a very nice monitor. Its retail price is quite high, though, so I suggest looking at the specs and reviews for other 4K monitors to see if they might fit your needs at a lower price. The 27" market is crowded, and the 32" less so, with 40" a rarity, but once you see a 4K display you might never want a 1080p monitor again, and you'll look at your 1366x768 laptop with disdain for its shortcomings.
