We’d opt to use the monitor around 50 to 75 percent brightness in a room with plenty of ambient light, and at 40 or lower at night. Finally, the 34GN850 has a two-port USB 3.0 hub, headphone jack, and power is delivered through a modestly sized external brick. Or do you forgo sRGB clamping to fix greyscale? This mode is unusable due to white trailing and haloing. Colors also remain accurate to a moderate angle but lose accuracy before the brightness decreases. It has a 21:9 aspect ratio, a 1440p resolution, and its IPS panel has excellent viewing angles, so the image looks good regardless of where you sit. If you want a monitor with better build quality, take a look at the Dell Alienware AW3420DW. The LG 25UM58 has a 21:9 IPS Ultrawide Monitor that offers crisp and sharp display. That will cause visible fringing around text, so the 8-bit color option is preferable. The 34GK950F supports HDR, and it has an optional black frame insertion feature for clearer motion. It’s possible IPS technology will remain relevant for years to come. The 950F was a $1,200 display which was on the expensive side despite its quality. The bad news, is that the sRGB mode locks you out of all color controls except brightness and contrast, so you are stuck with whatever greyscale calibration you get from the factory. However, it’s not the fastest nor the optimal choice. Copyright ©2020 Designtechnica Corporation. VA ultrawides naturally have an advantage as well, anywhere from 2x to 3x the contrast ratio. You’ll want to use the single DisplayPort 1.4a connector to unlock the 144Hz refresh rate and 10-bit color depth, as using one of the two HDMI inputs will limit your maximum refresh rate to 85Hz with 10-bit colors. Flip to the front of the display, and we’re happy to say LG upgrades the finish where it counts. Portrait CALMAN Ultimate, DeltaE Value Target: Below 2.0, CCT Target: 6500K. A last-gen mid-tier GPU, like the AMD Radeon 5700XT or Nvidia GTX 2070 Super, would work as well. The 34GK950F was no slouch in terms of response times, but this new ultrawide panel should elevate the 34GN850 to the next level. Now that we’ve covered the drawbacks of the 34GN850, it’s time to get into the good stuff. If you want a monitor with an even higher refresh rate, the LG 34GN850-B's refresh rate can be overclocked up to 160Hz. A notable omission here is no backlight strobing mode, although as we found from the ViewSonic XG270QG, these new Nano IPS panels are essentially incompatible with backlight strobing due to the backlight’s design, which causes notable red fringes while using a strobing feature. The LG 34GN850 iterates on that winning formula with a few notable improvements. This where IPS is starting to show its age, especially against modern technologies such as OLED screens and VA panels, although those come with their own drawbacks. The back of the monitor is made from smooth brittle plastics with a red ring around the mounts and IO. The 38GL950G-B has a faster response time and its refresh rate can be overclocked up to 175Hz. Saturation when assessing this display against sRGB suffers from the usual lack of an sRGB gamut clamp, which noticeably oversaturates colors. The LG 34GK950F has an excellent response time. © 2020 TechSpot, Inc. All Rights Reserved. The LG 34GK950F-B shows no signs of temporary image retention, even immediately after displaying our high-contrast static test image for 10 minutes. Although it can't be used in portrait mode due to its wide format, it has decent height and tilt adjustment range. The 34GN850 is great not only for immersive competitive gaming, but also for productivity. The 34GK950 is also available with G-SYNC instead of FreeSync. The LG 34GK950F-B is a great gaming monitor. We’re only talking 11% faster, which is nice to have, but reasonably negligible in the grand scheme of things. Then at 60Hz, you’ll see what we were talking about earlier. The 34GK950F-B has a decent build quality overall. If someone comes across a different type of panel or if their 34GK950F doesn't correspond to our review, let us know and we will update the review. Colors have great accuracy, and most people won't notice any issues. The overall design of LG monitors hasn’t changed much in the last few years.

Its reflection handling is mediocre, though, so it's best to avoid having light shining directly on the screen. The LG 34GN850 has great brightness, nearly 400 nits which is in keeping with its DisplayHDR 400 rating, although it does lack true HDR functionality. The 34GN850 has VESA DisplayHDR400 certification, which is the lowest tier of HDR monitors come can carry. LG 29UM57-P Ultrawide Monitor Calibration. Its large screen size and ultrawide format are great for having multiple windows open at the same time. You’ll find that annoying if you work or play in a dark room. This isn’t a bad showing from LG’s Nano IPS panel all things considered, and isn’t that big of a deal in moderate to bright lighting conditions, but it is a weak spot for this monitor. Luckily, the 34GN850 is highly calibratable in either the default or sRGB modes, because performance out of the box is pretty good. I was using a 28" 4K 16:9 monitor and tried this one. Calibrating the monitor helped us pull 2% more AdobeRGB color space coverage, but dropped the peak brightness by 5 nits, and reduced the maximum contrast to 840:1. The LG 34GK950F-B is a very good monitor that provides ample screen space for productivity work as well as delivering a great gaming experience. You can opt to use the included stand with the monitor, but there are a few problems with it. It also has good viewing angles, perfect for sharing your screen with your clients or coworkers. Outstanding SDR color volume. As expected, we are seeing 27GL850-like performance from this monitor, almost matching its response time and inverse ghosting performance. The sides are a bit darker; however, the center of the screen is very uniform, with almost no dirty screen effect. However, my 34GN850 had a lot less IPS glow in the bottom left and right corners than my 34GK950F, this monitor (at least our unit) was much better than average for IPS glow and while it’s not perfect – very few IPS monitors are – I don’t think you’ll notice this issue in most conditions. It was mind-boggling just how fast, buttery-smooth, and clear the image was at 160 Hz. If you’re buying an ultrawide and you’re after image quality, you’ve come to the right display. The LG 34GK950F-B is a much better monitor than the Nixeus EDG 34. If you're looking for something less expensive, you do have alternatives, and the LG 34GN850 remains a premium option. We know the 34GN850 uses 1ms class Nano IPS technology, so this should mean 27GL850-like performance right? Due to the curvature of the screen, the LG 34GK950F-B is a bit thicker than most, even when VESA-mounted. While technically inferior, games still look great on an 8-bit panel. We tested the monitor with our Datacolor Spyder X Elite, and found that our retail sample is able to cover 88% of the AdobeRGB space and 94% of the DCI-P3 space, with colors reproduced at a Delta-E (difference from real) of 1.68. Eventually you'd find it around the $1,000 mark or lower on sale, which made more sense. If you want a monitor with an even lower input lag, take a look at the Nixeus EDG 34. Good HDR color gamut. LG is still using an IPS panel, but they’ve upgraded it to their latest 1ms Nano IPS tech, the same good stuff present in LG’s popular 27GL850. When you open the software with the monitor connected, it should automatically detect that a new firmware is available. ViewSonic included this feature and it was unusable, LG has decided not to which we feel is a better choice. The LG 34GK950F-B has a fairly simple design. The 34" model uses an IPS panel, with much wider viewing angles, and it has a wide format aspect ratio, which some people prefer.
