LG Monitor 27GN850-B 27GN850B 27" QHD Wide 1440p (27GN850)

Product Information

Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases. In this mode we really start to see the benefits of LG's Nano IPS technology and the additional tuning they've done with the new 27GP850. We get a response time average of 4.65ms which is fast, and that allows for 82% refresh rate compliance at 180Hz, impressive given our new and much stricter testing methods. Inverse ghosting has increased slightly but it's not noticeable in practice, and this leads to a great cumulative deviation result of 407. I also quite like how easy it is to access the 27GP850's ports on the rear, where you'll find a DisplayPort, two HDMI connectors and a couple of USB ports. This complicates wall mounting somewhat - this display does have a VESA mount - but I feel the ease of access is worth it. The overall rear design is nice, and I'm glad LG hasn't changed it substantially from previous monitors. Overall adjustability is decent, the range of height adjustability is generous, so it should be great for most users' ergonomic setup, and this is achieved with less wobble than previous designs. There's also tilt and pivot support in case you want to use the monitor in a portrait orientation.

Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches. After calibration top balance out gamma settings and color temperature, both monitors boast upwards of 99.6% sRGB color accuracy. Adobe RGB has 84.2% color accuracy on the 27GL850-B and 88.8% on the 27GN850-B as well, making both monitors perfect for people switching between gaming and content creation. However I also think that's being a bit unfair to LG. Usually when I talk about displays not delivering a single overdrive mode experience, it's because each mode is unusable at a certain point in the refresh range. That could mean decent performance at 144Hz but severe inverse ghosting at 60Hz. That's not really the case with the 27GP850, and the differences between the Normal and Fast modes are small overall. I actually found it quite hard to decide which mode is better for adaptive sync gaming, ultimately I settled on the Fast mode but overall it's a case where buyers can choose to either prioritize low overshoot with the Normal mode, or speed with the Fast mode, and get a pretty good experience across the board. HDR support is standard on both screens and shares the same technology and color boosting technology. While this mode can cause some issues otherwise with response time and refresh rate, it is a welcome boost for watching movies or generally consuming media. The big story around LG's Nano IPS panels has always been the contrast ratio. Unfortunately, LG have not been able to shift the needle significantly with this new generation.It's also a much more substantial update to the display than last year's refreshed 27GN850, with LG showing the clear goal of retaking the performance throne in this class of monitor. The percentage of the approximate area, taken by the active part of the screen, to the total front area.

Approximate height of the display. If the manufacturer does not provide such information, the height is calculated from the diagonal and the aspect ratio. Visit authorized LG retailers in Egypt to view our range of monitors and choose the right one for you. Information about the minimum amount of time, in which the pixels change from one color to another. Very often the manufacturer provides the response time for transition from grey-to-grey (G2G). Information about whether the stand can be dismounted. Usually, this is required for wall mounting.Moving into color performance now and like LG's previous Nano IPS displays, the 27GP850 also comes with a rated 98% DCi-P3 coverage, which in our testing measured in at 96%, among the best coverage of P3 that we've measured. Approximate diagonal size of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen.

Power consumption has decreased slightly across the generations. The 27GP850 consumes about 16% less power at the same level of brightness after calibration than the 27GL850, a modest improvement to efficiency but not that different to some other 27-inch 1440p gaming monitors that I've benchmarked. LG continues to provide impressive monitors for the gaming market. With the LG 27GP850, they company hasn't simply re-released a previous product with a few enhancements but LG has clearly assessed the market, noted that some newer IPS monitors were offering better performance, and stepped up their game with their 2021 27-inch 1440p monitor. This has led to several improvements over the prior model. Added text in the macOS Compatibility and Console Compatibility boxes as part of Test Bench 1.2. Also changed the FreeSync result in Variable Refresh Rate to 'Yes'. The big question though is how does the 27GP850 compare to other monitors on the market, and specifically how does it compare to the 27GL850? Well when talking about the best performance on offer at the maximum refresh rate, the 27GP850 comes out looking very strong. This newly tweaked display offers performance in line with other current-generation fast IPS products, and a step above the 27GL850. Overshoot remains about the same as the 27GL850 here, but the new model is 24% faster - plus we're getting the added benefit of 180Hz versus 144Hz which does improve clarity as well. The operating temperature shows the safe temperature range (from minimum to maximum), within which the display will function flawlessly. Outside this range it might operate improperly and/or fail entirely.

Speed

Contrast ratio and brightness are two categories that both monitors sadly fall short in. While the advertised ratios are respectable, plenty of real-world testing and monitor comparisons have provided some disappointing results. While the monitors are still great options, contrast is a major failing of the panel. If you work in a bright room or consistently see changing light around you, it may be best to consider other options. To be clear, it doesn't need that higher refresh rate to be better, even comparing 144Hz to 144Hz, the 27GP850 is better in terms of response performance, a product of tweaked and improved overdrive modes.

The storage humidity shows the lower and upper humidity limit, which ensures safe storage of the display. Storing it outside these limits might damage the display. The pixel pitch shows the distance from the centers of two neighboring pixels. In displays, which have a native resolution (the TFT ones, for example), the pixel pitch depends on the resolution and the size of the screen.Information about whether there is a possibility for wall mounting according to the VESA Mounting Interface Standard (MIS). When using the Normal mode, at 180Hz performance does improve noticeably compared to overdrive disabled, and LG has achieved this without increasing overshoot. A 6.5ms grey to grey average response time is in line with several other IPS monitors, but we can do better than this. Let's increase the overdrive up to Fast. When looking at cumulative deviation, we do see an improvement for the 27GP850, it now sits firmly among those new IPS panels we've just been talking about, although not generationally ahead. In comparison, last-gen versions like 27GL850, S2721DGF and AG273QXP all sit in the 580 to 540 range in this metric. So the 27GP850's result of 521 is in the range of 5 to 10 percent better, not a huge improvement but decent for what appears to just be overdrive tweaks, rather than an entire overhaul of LG's IPS technology - and it's doing this without variable overdrive. After some necessary post calibration, these two monitors are some of the best options available for color accuracy and gamut. Out of the box, they both struggle with correctly displaying blue tints, and the provided picture modes are nothing special. With that said, most users will not have any issues with the immediate options but taking some time to properly calibrate is a good idea. With no calibration, the 27GN850-B slightly edges out the 27GL850-B. First up we have performance in the Off mode, which is without overdrive. As expected we get virtually no overshoot, and we can see that native panel performance is around the 7.8ms mark on average. This is actually a very good result all things considered, but does fall short of what is required for a true 180 Hz refresh rate, so it might be time to enable overdrive.
