This confirms some fairly relaxed calibration measures for the screen that have been achieved as it comes out of the factory. No real control over the LED back lighting unless you use the software and the monitor is connected to the PC VIA a USB cable which has never worked for me trying 5 different cables and all the ports on a very modern AM4 Gigabyte motherboard. We separately measured the colour space using ChromaPure and thankfully confirmed that the sRGB gamut had been properly emulated, measuring 97. 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. It did lose some points for luminance uniformity as the left side of the screen was up to 20% dimmer in one test.
In our view you need a screen of about 40″ in size (like the Philips BDM4065UC for example) to use an Ultra HD or 4K resolution effectively without OS scaling. G2G response time here which was in line with the figure we had from our smaller sample set earlier.
The 27GN950 obviously offers 4K resolution and some other features, whereas the 27GL850 was “only” 1440p, but the Nano IPS panels performed very similarly when it came to these other areas. Instead, you should just use the ‘Fast’ mode which will make sure that all pixel transitions are made in time with the monitor’s 144Hz refresh rate thus eliminating ghosting and preventing inverse ghosting. It’s important to note that this is a G-Sync Compatible monitor and uses a Freesync module, not Nvidia’s proprietary tech. The stand is a matte black plastic colour and is thick and chunky, providing a sturdy and stable base for the display.

We have divided the table up by panel technology as well to make it easier to compare similar models.In fact it is arguable that the wide range of 2560 x 1440 resolution panels in the 27″ sector are about as high a resolution as you want to go, without making fonts and icons too small natively. Alternatively, consider the Acer XB283K KV with a USB-C port and 65W PD in case you have a compatible laptop.
The contrast ratio was improved a bit but remained very close to the default setup and the manufacturers spec of 1000:1. However, it can also make some colors appear over-saturated in content which was developed with the more common sRGB gamut in mind. The brightness range of the screen was wide with the ability to offer a luminance between 465 and 90 cd/m 2. You can certainly see chroma sub-sampling when you use that old method especially in desktop applications, but that was not necessary now that DSC was being used. 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.These adjustments before profiling the screen would help preserve tonal values and limit banding issues. You need to ensure you have the necessary operating system and applications to handle scaling effectively for your needs. Response time performance may well be different than at the higher refresh rates supported, and you may need a different overdrive setting for optimal experience. PC gaming for instance will be much less of a system drain at 1440p than at 4K, allowing you to potentially push up to higher frame rates and use higher settings. The screen has an external power supply and the screen also comes packaged with the power cable and adapter that you need.
