The LG 42 C2 OLED is a TV that's popular to use as a PC monitor, especially for gaming. It replaces the LG 48 C1 OLED, and it's available in a smaller 42-inch size with a headphone jack and wide-set feet that make it easier to use as a PC monitor. It has gaming features most high-end TVs have, like HDMI 2.1 bandwidth, a 120hz panel, and variable refresh rate (VRR) support, but it lacks other features monitors normally have, like a DisplayPort connection and an ergonomic stand. As it's a TV, it's also easy to stream content while you're not gaming as it has a built-in smart system, a tuner, and image processing features, so you don't need to use your PC to watch movies and shows.
Note: We tested the 65-inch model as a TV, which you can read about here. However, the results of the two reviews aren't comparable because of the different ways we score TVs and monitors. We also test them using different picture settings.
Our Verdict
The LG 42 C2 is great overall. It's amazing for gaming as it has a fast 120Hz refresh rate with HDMI 2.1 bandwidth and variable refresh rate support that make it ideal for console gaming or PC gaming with an HDMI 2.1 graphics card. It also has low input lag and a near-instantaneous response time for a responsive feel. It's fantastic for watching SDR or HDR movies in the dark because it displays perfect blacks, has no blooming, and highlights stand out. It's good for the office, as it has decent text clarity and wide viewing angles, but it doesn't get bright in PC Mode, meaning it isn't ideal to use in well-lit rooms.
- Fantastic reflection handling.
- Wide viewing angles.
- Perfect black levels.
- No blooming around bright objects.
- Not very bright in PC Mode.
- No ergonomic adjustments.
The LG 42 C2 is decent for the office. It has a large screen that makes it easy to open multiple windows at once, and the text clarity is decent too. It has wide viewing angles that make the image remain consistent from the sides, which is ideal if you need to share your screen with someone else or if you sit close. It has fantastic reflection handling that reduces the amount of reflections, but it doesn't get very bright. Unfortunately, it doesn't offer any ergonomic adjustments, but you can mount it if you want to adjust it. Also, OLEDs run the risk of permanent burn-in when exposed to the same static elements over time, like the static elements from the PC software.
- Fantastic reflection handling.
- Wide viewing angles.
- Large 42-inch screen.
- Flicker-free backlight.
- Risk of permanent burn-in.
- Not very bright in PC Mode.
- No ergonomic adjustments.
The LG 42 C2 is amazing for gaming. It has HDMI 2.1 bandwidth that allows you to play 4k games up to 120 fps from HDMI 2.1 graphics cards or current-gen consoles. It also has low input lag and a near-instantaneous response time for a responsive feel while gaming, and it has variable refresh rate (VRR) support to reduce screen tearing. It's also fantastic for dark room gaming as it has a near-infinite contrast ratio, and there's no blooming around bright objects. Unfortunately, it doesn't have a DisplayPort input, so you'll need an adapter if your PC doesn't have an HDMI port.
- HDMI 2.1 bandwidth.
- VRR support.
- Low input lag in Game Mode.
- Near-instantaneous response time.
- Perfect black levels.
- No DisplayPort input.
The LG 42C2 is fantastic for media consumption. It looks incredible in dark rooms thanks to its perfect black uniformity, and it has no blooming around objects. It's also big enough to comfortably share your screen with someone sitting next to you, and it has wide viewing angles. Although it doesn't get bright in Game Mode, it gets brighter outside of it to make colors look vivid, and it displays a wide range of colors in SDR.
- Fantastic reflection handling.
- Wide viewing angles.
- Large 42-inch screen.
- Perfect black levels.
- No blooming around bright objects.
- Not very bright in PC Mode.
The LG OLED42C2 is great for content creators. The big screen has enough screen real estate to easily see your entire work area at once. It also has decent text clarity, but editing programs don't support the RWBG subpixel layout, meaning text doesn't look as clear in some programs. It also has wide viewing angles that make the image remain consistent from the sides, but it doesn't come with an ergonomic stand if you need to swivel the screen to show a client or coworker. Sadly, OLEDs risk permanent burn-in with constant exposure to the same static elements over time, like if you constantly have your editing program open.
- Fantastic reflection handling.
- Wide viewing angles.
- Large 42-inch screen.
- Flicker-free backlight.
- Risk of permanent burn-in.
- Not very bright in PC Mode.
- No ergonomic adjustments.
The LG 42 C2 is amazing for HDR. It displays perfect blacks without any blooming around bright objects, meaning it's a fantastic choice for watching movies in the dark. It also delivers a satisfying HDR experience because small highlights pop, and it displays a wide range of colors with minimal banding between shades of similar colors. However, it has only decent color volume, meaning it struggles to display some very vivid colors.
- Perfect black levels.
- No blooming around bright objects.
- Near-perfect DCI-P3 coverage.
- Small highlights pop in HDR.
- Limited Rec. 2020 coverage.
- Only decent color volume.

Differences Between Sizes And Variants
We tested the 42-inch LG C2 OLED, and it's also available in larger sizes. For the most part, the results are also valid for the 48, 55, 65, 77, and 83 inches, but text clarity is worse on large sizes because they have lower pixel density. We tested the 65-inch model as a TV, but the results aren't comparable between the TV and monitor review because we tested each with different settings and methodology. Although it's not really a variant, LG also released the LG 48GQ900-B, which is a very similar display to the C2, but with features and inputs more typically found on monitors.
| Size | US Model | Stand Type | Headphone Port |
|---|---|---|---|
| 42" | OLED42C2PUA | Feet | Yes |
| 48" | OLED48C2PUA | Wide Center Stand | Yes |
| 55" | OLED55C2PUA | Narrow Center Stand | No |
| 65" | OLED65C2PUA | Narrow Center Stand | No |
| 77" | OLED77C2PUA | Narrow Center Stand | No |
| 83" | OLED83C2PUA | Narrow Center Stand | No |

Popular Monitor Comparisons
The LG C2 42 is a great display with better picture quality than most monitors, thanks to its perfect black levels. It's an amazing choice for console gaming or PC gaming with an HDMI 2.1 compatible graphics card, and the smaller screen size is an advantage compared to past C Series models that were available in 48 inches. Of course, you lose out on features found on other monitors like a high refresh rate, a DisplayPort connection, and an ergonomic stand, but if you want an OLED to use as a gaming monitor, it's amazing.

The LG C4 42 OLED is a newer version of the LG C2 42 OLED. Some of the changes with the C4 include a brighter screen, more vivid colors, and a slightly higher refresh rate, making it the better choice in most cases. However, if you can find the C2 for less and don't mind the reduced brightness, you won't be disappointed by the older TV.
The LG C2 42 OLED and the ASUS ROG Swift OLED PG42UQ are both 42-inch OLED displays with a few differences. The LG is a TV, so it has more built-in features like a smart system and image processing, but the ASUS is a monitor with a USB hub and a DisplayPort input. In terms of picture quality, they're very similar, but the ASUS gets brighter in HDR; you just need to make sure it's updated to the latest firmware for the best performance.
The LG 48 CX OLED and the LG C2 42 OLED are very similar. If you care about text clarity, the C2 is a better choice because it has a smaller screen with improved text clarity. Other than that, they're both very similar overall, but the C2 has a few more features.
The LG C1 48 OLED and the LG C2 42 OLED are very similar, with the main difference being that the C2 is smaller. The smaller size increases pixel density, resulting in slightly better text clarity. The C2 also has a different stand that makes it easier to route your keyboard and mouse cables through. However, if you care about HDR or want to use the monitor in a bright room, the C1 gets brighter.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
