LG 27EP950-B 27” Ultrafine UHD (3840 x 2160) OLED Pro Display with Adobe RBG / DCI-P3 99%, VESA Display HDR 400 True Black, 1M:1 Contrast Ratio and Tilt/Height/Pivot Adjustable Stand - Black

Wow, what a gorgeous display. Never seen anything like it. The whites as so white and the blacks so black. OLED is the real deal. Really exceptional color controls, excellent pixel size without gaps. Incredibly sharp. If you have a single monitor setup or are viewing this from far away, this is the display for you. 100% full range dimming on each pixel is amazing, as is the 10-bit color and full set of device interfaces (USB-C DP Alt Mode, HDMI and 2x display port. So good.The color is exceptional. The display really hits those fluorescent orange tones that I haven't seen anything else reproduce since the Dell UP2715K came out. Color controls are straight forward and useful, but not overly complex. Display remembers color modes for each interface which is really nice.Sadly if you have a two display setup and you sit in-front of one, there are major color shift problems at around 45 degrees where the other display would normally be. At that angle the color temperature gets very warm (excessive red). At an additional angle it normalizes and then has a hard shift to being very cool (blue) with a nasty gradient.I have compared this monitor to the Apple XDR, Apple Studio Display, Dell UP2715K, Dell UP2720Q and LG 27MD5KL-B. For a single monitor setup or a situation where I could sit further away from the display I would choose this one in a heart beat out of all of those.Unfortunately I do color grading so I can't tolerate the color shifts and am returning the display. My next choice would be the LG 27MD56KL-B which does not color shift even at extreme angles.Calibration out of the box was really off, and had poor repeatability comparing the two monitors I received, but can be adjusted with a calibrator - not the end of the world, but should be a lot better given the price.

I use this monitor for professional office work and occasional gaming. Despite calibration, the white balance is way off and there is almost no way to fix it. I fix it with a calibrator and a lot of manual adjustments (HDR mode) however at the expense of color accuracy. Disappointed overall for the price. Slow refresh rate too - 60Hz.The black are fenomenal and are the reason I decided to keep this monitor.

As a videophile going back to the 1970s, I've owned a number of professional monitors from the likes of Tektronix and Sony. I've been looking for something with exceptional quality in the under 30-inch range, as there is nothing whatsoever that fits that bill when it comes to consumer televisions. Thus, I was intrigued when I heard about this 27-inch LG OLED, as it seemed to be just what I was wanted. I held off buying it for some time, not quite sure if it would live up to my expectations. All I can say is, it exceeds my expectations in every regard.I am using this as one might use a television, with sources ranging from DirecTV to Apple TV 4K. I am pleased to report that it excels with ALL sources. It upscales beautifully from 1080i, with no visible artifacts. 4K content from the Apple TV looks absolutely stunning -- it's like looking out a window. To appreciate all the detail really requires a magnifying glass.Color rendition is first-rate, displaying a range of colors that simply aren't seen on LCD screens. Being an OLED, of course the blacks are perfectly black. I'm not a fan of HDR, so I've been viewing only in SDR, and the monitor affords more than enough light output -- I even had to reduce the brightness from the factory settings as it was brighter than I like.I appreciate the fact that being a "pro" monitor, it doesn't have any annoying "smart TV" features. Turn it on and whatever is at the input is immediately displayed. There's also no need to go through a ton of menus to disable all the junk that plagues consumer TVs -- stuff like noise reduction, motion interpolation (which creates the hideous "soap opera" effect), and the like. It just looks RIGHT, without all that sleaze. Since this monitor is intended to present "the truth" to content creators, that is as it should be.I've seen some other reviews that mention uniformity issues, but I'm not seeing that here. A flat white field looks uniformly white from edge-to-edge. Perhaps there are variations between samples?Simply put, I'm extremely picky about displays, and I'm 100% pleased with this monitor. Highly recommended.

Colors are great, as one should expect from an OLED monitor. However, there are serious problems with white uniformity. All you have to do is open a Word doc and the absence of white uniformity is very noticeable from one edge of the screen to another. If the primary goal is to color intensive work, this might be fine. However, for mixed usage involving productivity I'd stay away at this price point.

This display is a top notch professional display. It also doubles as a good gaming display despite the 60Hz refresh. The true blacks, ultra-crisp text, and highly calibrated colors are on point.
