The LG GX is a new TV in LG's 2020 lineup with a unique 'Gallery' design. It's a very thin TV that comes with a wall-mount instead of a stand, and it's meant to sit flush against the wall. Picture quality is excellent; like any OLED, it can individually dim pixels, resulting in an infinite contrast ratio and perfect black uniformity. It displays a wide color gamut for HDR content, but it has an aggressive Automatic Brightness Limiter, so large areas aren't bright. It has variable refresh rate (VRR) support, a near-instant response time, a Black Frame Insertion feature, and low input lag for gaming. Unfortunately, like any OLED, it has the risk of permanent burn-in, which can be an issue if you watch content with static elements all the time, like the news, but it shouldn't pose too much of a problem if you watch varied content. Lastly, it has wide viewing angles, which is great for wide seating arrangements.
Note: We bought the optional stand with the TV for testing and didn't use the included wall-mount. We've read reports of people having a hard time setting up the TV, but this isn't something we test for. If you experience any issues, let us know in the discussions. If you don't plan on wall-mounting it, the LG CX OLED is a very similar TV that comes with a stand and costs less.
Our Verdict
The LG GX OLED is an amazing all-around TV. It's an ideal choice for watching movies in a dark room because of its nearly infinite contrast ratio and perfect black uniformity. Gamers should enjoy the 120Hz refresh rate, VRR support, near-instant response time, and low input lag. It also has wide viewing angles if you want to watch the big game in a wide seating arrangement. Unfortunately, it has the risk of permanent burn-in, so it's not ideal to use as a PC monitor because of the static elements of most user interfaces.
- Nearly infinite contrast ratio.
- Wide viewing angles.
- Near-instant response time.
- VRR support.
- Aggressive Automatic Brightness Limiter (ABL).
- Risk permanent burn-in.
The LG GX OLED is an incredible TV for watching movies. It has a nearly infinite contrast ratio and perfect black uniformity, so movies in a dark room look amazing. It upscales lower-resolution content well, and it removes 24p judder from any source. Sadly, because this TV has a near-instant response time, lower frame rate content may appear to stutter.
- Nearly infinite contrast ratio.
- Perfect black uniformity.
- Removes 24p judder.
- Upscales 720p and 1080p content well.
- Low frame rate content may appear to stutter.
Great for TV shows. The LG GX has very wide viewing angles, great if you walk around while watching your favorite show. It has outstanding reflection handling but may not get bright enough to combat glare in well-lit environments. It upscales lower-resolution content, such as from cable boxes, without any problems. Unfortunately, it has the risk of permanent burn-in, which may be an issue if you constantly watch content with static elements, like the news.

The LG GX is excellent for watching sports. It has a near-instant response time, resulting in minimal motion blur, and it has wide viewing angles if you want to watch the game with a large group of friends. It performs well in bright rooms because it has outstanding reflection handling, but it doesn't get bright enough to combat a lot of glare. Our unit has a uniform screen with no dirty screen effect, but this may vary between units.
- Wide viewing angles.
- Outstanding reflection handling.
- Near-instant response time.
- Aggressive Automatic Brightness Limiter (ABL).
Outstanding for video games. The LG GX has a 120Hz refresh rate and VRR support to reduce screen tearing. Its response time is near-instant and it has a Black Frame Insertion feature. Input lag is also incredibly low. Also, it's amazing for dark-room gaming because of its nearly infinite contrast ratio. Sadly, it has the risk of permanent burn-in if you constantly play video games with an interface that has a lot of static elements, but we don't expect this to be an issue for most people.
- Near-instant response time.
- Low input lag.
- VRR support.
- Risk permanent burn-in.
Excellent for HDR movies. The LG GX has an infinite contrast ratio, displaying extremely deep blacks, and it has perfect black uniformity. It displays a wide color gamut for HDR, but it may not get bright enough in HDR to truly bring out highlights. Lower frame rate content may appear to stutter because of its near-instant response time. However, it can remove 24p judder from any source.
- Nearly infinite contrast ratio.
- Perfect black uniformity.
- Removes 24p judder.
- Displays wide color gamut.
- Aggressive Automatic Brightness Limiter (ABL).
- Risk permanent burn-in.
The LG GX is excellent for HDR gaming. It's packed with gaming features like VRR support, near-instant response time, and low input lag. HDR content looks good because it displays a wide color gamut, but it doesn't get very bright in that mode to truly make highlights stand out. Due to this TV's nearly infinite contrast ratio, it displays perfect blacks, great for dark-room gaming.
- Nearly infinite contrast ratio.
- Near-instant response time.
- Low input lag.
- Displays wide color gamut.
- Aggressive Automatic Brightness Limiter (ABL).
- Risk permanent burn-in.
The LG GX is an excellent choice to use as a PC monitor. It has wide viewing angles, low input lag, and near-instant response time. It also displays chroma 4:4:4, which is important for reading text. Sadly, it has the risk of permanent burn-in, so static elements from a computer's interface may damage the screen over time, but this shouldn't be a problem if you watch varied content.
- Wide viewing angles.
- Outstanding reflection handling.
- Low input lag.
- Aggressive Automatic Brightness Limiter (ABL).
- Risk permanent burn-in.

If someone comes across a different type of panel or if their LG GX doesn't correspond to our review, let us know and we'll update the review. Note that some tests such as the gray uniformity may vary between individual units.
The GX we reviewed was manufactured in March 2020, and you can see the label here.
Popular TV Comparisons
The LG GX is an excellent TV and like most OLEDs, it delivers exceptional picture quality. However, it doesn't stand out much against the cheaper LG CX OLED, so if you need a stand or you simply want to VESA-mount the TV, the GX isn't worth it for its price. Also see our recommendations for the best 4k TVs, the best OLED TVs, and the best LG TVs.
In terms of picture quality, the LG GX OLED and the LG CX OLED are two very similar TVs and any differences come down to panel variance. Our unit of the CX has much better color accuracy, better gradient handling, and it gets slightly brighter. However, our unit of the GX has wider viewing angles. The major difference between them is that the GX comes with a wall mount that makes it sit flush against a wall, while the CX comes with a stand.
The LG GX OLED and the LG G2 OLED deliver a very similar experience. The G2 uses a newer OLED panel, which gets a lot brighter, especially in HDR, so bright highlights stand out better. On the other hand, the GX's black frame insertion feature is a bit more versatile, as it supports a 120Hz flicker with 120Hz content, whereas the G2 can only flicker at 60Hz.
The LG G1 OLED replaces the LG GX OLED, and they're each very similar. The main difference is that the G1 has the new evo panel, allowing it to get brighter than the GX in HDR, so small highlights pop more. The G1 comes with a redesigned remote and an updated version of the built-in webOS, but other than that, the TVs each deliver similar, exceptional picture quality.
The LG C9 OLED and the LG GX OLED are two similar TVs with different designs. The GX is meant to be wall-mounted and comes with a dedicated wall-mount instead of a stand. It also has a wider VRR range, a Black Frame Insertion feature that flickers at 120Hz, and better speakers. On the other hand, the C9 comes with a stand and has better out-of-the-box color accuracy, but this may vary between units.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
