Lg - 55 Class (546 Diag) - Oled - 2160p Reviews

The LG GX OLED is a high-end TV in LG'southward OLED lineup. It's a new Telly in 2020 and it sits correct below the LG WX, which is an even thinner TV that comes with an external box instead of having the inputs on the TV. Its main competitors are the LG CX OLED, the Sony A8H OLED, and the Samsung The Frame 2020.

Design

LG GX OLED Design Picture

Curved No

The LG GX has an incredible blueprint. Information technology's very thin and the TV has a uniform thickness throughout. There are tapered edges where the front and back panels meet, which allows the TV to sit flush against the wall when wall-mounted, making it look like a picture frame. It comes with LG's Affluent Wall Mount, and y'all can buy feet separately if you don't want to wall-mountain it.

LG GX OLED Stand Picture

LG sells anxiety you can buy separately for this stand up, which is what we did, and they hold the Telly well. If yous don't program on wall-mounting it, then consider the LG CX OLED, which is a very similar TV that'southward cheaper and it comes with a stand.

Footprint of the 55" stand up: 45.4" 10 10.seven".

Note: If you buy the feet separately you also get input covers.

Wall Mount VESA 300x300

The back of this Boob tube is made out of metal. In the photo, there'south a encompass where the defended wall-mountain goes, and yous can also VESA-mount it if you choose. There'south an L-shaped console covering the inputs and information technology allows y'all to route wires to the center of the Television set if you wall-mount information technology. There's as well cable direction through the optional feet.

Notation: The input covers come with the feet if y'all buy them separately.

Borders 0.35" (0.9 cm)

The borders are sparse and aren't distracting.

LG GX OLED Thickness Picture

Max Thickness 0.94" (2.4 cm)

The LG GX is very sparse and won't stick out when wall-mounted. It's fifty-fifty thinner than the Samsung The Frame 2020.

LG GX OLED Build quality picture

Incredible build quality. The LG GX is extremely well-made with a unique design. The back is mainly fabricated out of metal that doesn't flex much and there aren't whatever visible build quality issues.

Automatic Brightness Limiting (ABL) 0.051

The LG GX has okay pinnacle effulgence. Information technology gets vivid enough to gainsay glare in moderately-lit rooms, but information technology may not exist practiced plenty for a vivid environment. Because of its ambitious Automatic Brightness Limiter (ABL), its brightness isn't very consistent beyond unlike content and it quickly becomes dim with large, bright areas.

We measured acme brightness before calibration, although we usually accept the results later on calibration. This is because calibrating the TV significantly improved the 100% peak window up to 269 cd/m², while the other results simply slightly improved by one or two nits. Since scale changes per unit of measurement, not every TV would get brighter similar ours, and some may get dimmer.

We measured the SDR height brightness in the 'Expert (Dark Room)' Picture Mode with OLED Light at its max and Peak Brightness setting on 'High'. We got the brightest image possible with these settings, as seen in the 10% peak window test.

Local Dimming No

Backlight No Backlight

Update 07/26/2021: We've added two new videos demonstrating the backlight behavior with existent content.

Since this Telly doesn't have a backlight, it doesn't have a local dimming feature. Information technology tin dim pixels individually, so vivid objects and subtitles are displayed perfectly, with no visible blooming.

Decent brightness in HDR. This TV gets bright plenty to bring out pocket-size highlights in HDR. However, similar in SDR, it apace loses its brightness as large, bright areas cover the screen considering of its aggressive ABL. If you want an OLED that gets a flake brighter in HDR, check out the Sony A90J OLED.

We measured HDR tiptop brightness in the 'HDR Picture palace' Picture Mode with OLED Light at its max, Peak Effulgence fix to 'High', and Color Temperature set to 'Warm ii'.

Update 12/08/2020: We remeasured the accuracy after calibrating our spectroradiometer. The review has been updated.

Decent out-of-the-box color accuracy. Most colors are slightly inaccurate and white balance is off, which affects shades of gray. The color temperature is slightly cold and for the most part, gamma follows the target curve well, except extremely bright scenes may be too brilliant.

We had to calibrate the Television receiver twice because we had difficulty calibrating the 5% and 10% grayness stimulus levels while being connected to HDMI 1. We calibrated it once again through HDMI ii, and then these results are taken from HDMI two. The color accuracy only slightly improved and you can see our original results from HDMI 1 here:

Color Calibration Aye

Later on calibration, color accuracy is nearly perfect. Any remaining inaccuracies are almost impossible to spot with the naked eye and the color temperature is extremely close to the 6500K target.

We originally calibrated the LG GX through HDMI 1. While trying to calibrate the 10% grayness stimulus, information technology heavily afflicted the 5% gray stimulus to the point where the screen looked blue. This made it difficult to get a proper paradigm post-scale. We recalibrated information technology a 2nd time on HDMI two, and even though it slightly decreased the final score, it resulted in a better final image.

LG GX OLED 480p Picture

This TV upscales 480p content well, with no obvious upscaling artifacts.

LG GX OLED 720p Picture

The LG GX upscales 720p content, such every bit from cablevision boxes, without any bug.

LG GX OLED 1080p Picture

1080p content looks nearly as good every bit native 4k content.

LG GX OLED 4k Picture

The LG GX displays 4k content without any problems. Fifty-fifty though it has an RGBW pixel structure, all four sub-pixels are never on at the aforementioned fourth dimension, then in that location's no loss in color resolution.

The LG GX is a 4k TV that can't display an 8k indicate.

LG GX OLED Pixels Picture

The LG GX has an RGBW pixel structure, but all four pixels are never used at the same time. The image to a higher place shows the white, blue, and green subpixels. Yous can come across alternating pixel pictures here: Photograph 1 and Photo two. This pixel structure isn't ideal for use as a PC monitor because it affects the fashion text is displayed.

Excellent color gamut. This Idiot box has near-perfect coverage of the DCI P3 colour infinite used in near HDR content and decent coverage of the wider Rec. 2020 colour space.

The EOTF follows the target curve fairly well until it rolls off at its peak brightness. The EOTF in 'Game' mode is most the exact same.

If you discover HDR too dim, enable Dynamic Tone Mapping and set Dynamic Contrast to 'Medium'. It resulted in a bit brighter prototype, as you can see in this EOTF.

Grey (Std. Dev.) 0.123

Proficient slope handling, but it's not as good as the LG CX OLED. In that location's noticeable banding in grays and greens and a bit in reds and blues. Setting Smooth Gradation to 'High' helps smooths out gradients in real content, simply information technology didn't bear on the test blueprint. Setting it to 'Medium' or 'Low' doesn't affect the gradients all that much. If yous want an OLED Goggle box with better slope handling, check out the Sony A9S OLED.

The LG GX doesn't take any temporary image retention, fifty-fifty after displaying a loftier-contrast static epitome for 10 minutes.

Notation: Temporary image retention may vary between units.

Permanent Burn down-In Risk Yes

Unfortunately, like most OLED TVs, the LG GX isn't allowed to permanent burn-in. However, we don't wait people who scout varied content to take whatever issues, but rather it's a trouble if there are abiding static displays, like if it's used as a PC monitor.

This TV has three features to help burn-in run a risk. Enabling Screen Shift selection, and setting Logo Luminance Aligning to 'Low' may help with this. There's besides an Automatic Pixel Refresher that can be run manually if needed.

You lot can read well-nigh our investigation into this here.

If you're worried almost burn down-in and would prefer a high-end LED TV, check out the Samsung Q900TS 8k QLED.

Optional BFI Aye

Min Flicker For 60 fps sixty Hz

60Hz For 60 fps Yes

120Hz For 120 fps Yes

Min Flicker for 60 fps in Game Mode lx Hz

The LG GX has a Black Frame Insertion feature that helps amend the appearance of move. For it to flicker at 60Hz for 60fps content, ready TruMotion to 'User' and OLED Motion to 'Loftier'. It always flickers at 120Hz for 120fps content if you have TruMotion enabled with OLED Motion on whatsoever setting. The BFI characteristic doesn't look as practiced with 120fps content equally it does with 60fps content (in a higher place photo) and the crosstalk is bad, so there may be some motility artifacts.

LG GX OLED Motion Interpolation (30 fps) Picture

Motion Interpolation (xxx fps) Yes

LG GX OLED Motion Interpolation (60 fps) Picture

Motion Interpolation (60 fps) Yes

The LG GX can interpolate lower frame rate content up to 120fps, which is known as the 'Soap Opera Effect'. It does a proficient job at smoothing out motion and it doesn't stop interpolating even in busy scenes, merely this may pb to artifacts with fast-moving content. However, the artifacts are difficult to discover and non too distracting.

Come across here for the settings that control the motion interpolation feature.

Frame Concur Time @ 24 fps 39.4 ms

Frame Hold Time @ threescore fps 14.iv ms

Due to the TV's very quick response time, there'due south noticeable stutter with lower frame rate content because each frame is held on longer. Enabling the motion interpolation feature can help reduce this issue.

Judder-Complimentary 24p Yes

Judder-Free 24p via 60p Yes

Judder-Complimentary 24p via 60i Yeah

Judder-Free 24p via Native Apps Yes

The LG GX removes 24p judder from whatsoever source, as long as Existent Movie theatre is enabled. It can remove judder from 24p content with OLED Motion set to 'Machine', 'Low', or 'Medium'. Nevertheless, it doesn't remove judder with OLED Motion set to 'High' becauses the backlight flickers at 60Hz. With 60p content, you have to set OLED Motion on 'Medium' or 'Car' because 'Low' doesn't remove judder completely.

Update 11/04/2020: We've retested the input lag at 4k @ 120Hz with chroma four:4:four and VRR using an HDMI 2.i source. The results are consequent with the LG CX OLED's.

The LG GX has the same low input lag as the LG CX OLED. Information technology'southward the everyman with VRR enabled, which is great. To achieve the lowest input lag possible, you accept to be in 'Game' mode. The TV has an 'Automobile Depression Latency Way' that automatically switches into 'Game' fashion when a game from a compatible device is launched. For it to work, simply enable Instant Game Response. Sadly, you tin can't use the motion interpolation feature in 'Game' mode.

If you're using this TV as a PC monitor and want the lowest input lag possible, set the input icon to 'PC' in the Home Dashboard.
