Introduction

Looking for a USB-C 4K display for your notebook?

Would you like FreeSync and HDR for PC / console gaming too?

Well, the LG 27UK850 offers a reasonable price for all that!

Image Quality

The LG 27UK850-W monitor is based on an IPS panel that ensures precise, consistent and vibrant colors that make the display suitable for professional photo editing tasks.

It supports 10-bit color depth (8-bit + 2-bit FRC) and is factory-calibrated for over 99 percent of the gamut coverage of sRGB colours.

The 4K UHD resolution offers incredible quality of view with over 8 million pixels which on the 27″ screen of the LG 27UK850 display result in a high pixel density of 163 pixels per inch.

Having a high pixel density would make it look small, so you’ll need to scale up the interface to make everything larger, crisper and more accurate in effect.

In addition, the 350-nit peak brightness gets a small but noticeable boost to 450-nits when viewing HDR-compatible content.

The LG 27UK850 however lacks the correct color gamut and contrast ratio for a top-level HDR (High Dynamic Range) viewing experience.

A monitor does not qualify for VESA entry-level HDR certification without at least 90 per cent of the DCI-P3 color gamut.

However, some HDR content on the LG 27UK850 does definitely look better and more vivid, but it’s not nearly as good as on some more powerful HDR monitors.

Performance

The LG 27UK850 4K monitor has minimal backlight bleeding and IPS glow while the input lag performance is top-notch of around 10ms.

Overall the output of the display is without problems. The wide viewing angles of 178 ° make sure the image looks amazing no matter the angle you look at the screen.

The LG 27UK850 is also flicker-free and has a built in filter against the harmful low-blue lights.

Set the ‘Response Time’ setting in the OSD (On-Screen Display) menu to ‘Faster’ when it comes to gaming, to get the advertised response time of 5ms.

No prominent ghosting or motion blur is noticeable even in fast-paced video games, although a refresh rate of 60Hz will be very slow if you are used to higher refresh rate displays; however, if you prefer better graphics than performance, 4K more than makes up for it.

Features

The LG 27UK850 HDR display provides a range of additional features on the run.

All common features found on LG monitors, such as On-Screen Control (to adjust OSD settings in a desktop app), Screen Split (to divide the screen into different multitasking layouts), and advanced picture adjustments, such as 6-axis, gamma, etc.

Other gaming features include Black Stabilizer, which changes the gamma curve in dark parts of the image for more visible details, Dynamic Action Sync, which further reduces the input lag, and pre-calibrated presets for FPS and RTS game genres.

You can simulate HDR for non-HDR content, using the HDR Effect feature. There are four different HDR modes, in addition: HDR Vivid, HDR Standard, HDR Game, and HDR Cinema.

Finally, if you attach the monitor to a compatible AMD graphic card or Xbox One console, the LG 27UK850 supports AMD FreeSync which provides a variable refresh rate.

FreeSync removes all screen tearing and stuttering for a smoother gameplay experience, with minimum input lag penalty.

The FreeSync rate for the LG 27UK850 is 40-60Hz / FPS (frames per second). So, as long as your FPS rate stays within that range, you’ll experience no screen tears nor stutters.

Design & Connectivity

The monitor ‘s design is modern yet simple with thin bezels so it fits in any environment.

In addition , it provides flexible ergonomics including height adjustment up to 110 mm, -5 ° /20 ° tilt, 90 ° turn, and VESA mount compatibility with 100 x 100 mm, but you can’t swivel the screen to either left or right.

The 27-inch LG 27UK850 monitor features rich networking options including two HDMI ports, a DisplayPort, a USB-C port, a dual USB 3.0 hub, a headphones jack, and two 5W MaxxAudio built-in speakers.

The USB-C port supports Alternate DisplayPort mode and power delivery up to 60W. So, with just one cable, you can switch 4 K video , audio, data and power at the same time.

Note that the USB-C port is limited to a USB 2.0 bandwidth when used for purposes other than as the upstream port.

All display ports do support HDCP 2.2, so the Netflix content can be streamed, Amazon Video, etc in 4K UHD. FreeSync works over both HDMI and DisplayPort with a 40-60Hz dynamic range.

Price & Similar Monitors

The price of the LG 27UK850 is $549.99 MSRP which is relatively appropriate considering its multitude of features, performance and image quality.

Check out the LG 27UK650 which is a more compact 4K HDR model if you are looking for a similar display but do not need USB-C.

Conclusion

All in all, the LG 27UK850 IPS monitor is great for anyone needing an HDR, FreeSync and USB-C 4 K panel.

It has great design, rich connectivity, and plenty of extra features for both gaming and everyday use. All that for a fair price.
