If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen. Add+ Monitor Fan noise -- If I over clocked this monitor to get it to 160 and was in a hot room the monitor fans would kick on and stay on to the point where i would put on my head phones to drown it out along with my video card. You can thankfully still adjust this if you like, it’s not locked like brightness is on many screens in the sRGB mode. The default colour temperature was a little too cool at 6858k (6% out from our target), although not too bad. Note that the overclocked refresh rate of 160Hz is only available at 4K resolution, it is not available at 1080p or 1440p.

The light AG coating of the panel is welcome, and much better than the grainy and dirty appearance of older IPS AG coatings. We’ve seen very popular models like the 27″ 27GL850 with 1440p resolution and 144Hz, 34″ 34GK950F with 3440 x 1440 resolution and 144Hz, and 37. This can also help retain contrast, tonal values and ensure gradients remain smooth as corrections are carried out at the hardware level, and not at the graphics card level. We used the X-rite i1 Pro 2 Spectrophotometer combined with the LaCie Blue Eye Pro software package to achieve these results and reports.For PC connectivity the DisplayPort is the most common option and required to support the maximum resolution and refresh rate of the screen, with HDMI being available then for connecting external games consoles or Blu-ray players potentially. The monitor includes two HDMI inputs, but you’ll need to use DisplayPort to take advantage of everything it has to offer. The brightness range of the screen was wide with the ability to offer a luminance between 465 and 90 cd/m 2.

The SpyderX Elite sensor works in tandem with a software suite to assign a score to different sections of a display’s performance and you can see how it fared on the score card above. Contrast ratio had taken a small hit, and was now measured a 923:1, down from around 994:1 we’d seen out of the box but not by a massive amount. Colours looked vivid and bright thanks to the wide gamut backlight but the colour balance and temperature felt good.Of course, this also depends on what type of games you play, what PC setup you have or plan to get, and what frame rate and picture settings you’d be satisfied with. Height adjustment is also very smooth, maybe a little stiff moving it downwards but overall very good.

It is a little debatable whether you will gain much benefit from the higher PPI on a screen this size compared with a 2560 x 1440 standard model, but some may notice picture quality and sharpness improvements. Manual does not show any image of the back ports, the Update software asks for USB C - A connection and I wasn't sure if my monitor had a USB C connection or should I use the A ports to connect to a USB C port on the computer. The overdrive has been optimised here for achieving a good balance between driving faster response times, and avoiding too much overshoot creeping in at the lower refresh rates. If you press your ear up to the top of the screen you can hear it whirring away a little, so if you are super-sensitive to this kind of thing or have a silent PC then keep this in mind.The NVIDIA G-sync logo on the left hand side of the foot is a sticker by the way, so can be removed, whereas the LG logo on the right hand edge is etched on to the plastic finish and is permanent. There may be a need to switch between different overdrive settings in some cases, depending on your usually attained refresh rate output and graphics card capability. Other features include variable backlight, DFC (adjusts brightness according to the screen), and Smart Energy Saving – all of which we recommend leaving disabled for the optimal image quality.

It does make life a bit more complicated than if you just ran at a native resolution, which is where the more common 2560 x 1440 res fits in to the 27″ display space. I didn’t test it with an AMD GPU, but it is also compatible with FreeSync if you have a Radeon card. These optimal settings helped the screen look a bit better than out of the box, certainly helping with the brightness if nothing else. The on-screen reticle is the same as most monitors: great if you need it, but best avoided in online multiplayer to keep things fair. There were a couple of areas where the backlight shone through a bit more brightly in the lower corners, but they were hard to see in normal usage.Some people may find this problematic if they are playing a lot of darker games or watching darker movies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc.
