LG 24GS65F-B  Monitor Review

The LG 24GS65F-B has a gaming-oriented design with an all-black plastic body. Unlike other LG UltraGear monitors, it doesn't have any red accents, and the branding blends in with the rest of the monitor.

The build quality is good. The plastic materials feel solid with minimal bending, although the front bezel flexes a bit. There's glossy, reflective plastic along the outside of the housing that feels a bit cheaper, though. Besides that, there aren't any obvious defects, and even the stand holds the screen well.

The ergonomics are great. Besides not offering any swivel, you can adjust it how you like. The height adjustment feels smooth and easy to perform, but the other adjustments need some force. There's a small hook built into the stand for cable management.

The stand is large and takes up a lot of space, especially for a 24-inch monitor. It holds the screen well with minimal wobble, and even when it does wobble a bit, it stabilizes itself quickly. 

There's a joystick underneath the bottom bezel to control the on-screen display.

The LG 24GS65F-B has a disappointing contrast ratio. Blacks look gray against bright highlights, and it lacks a local dimming feature to improve this.

Though this monitor doesn't have local dimming, we still film these videos so you can compare the backlight performance with a monitor that has local dimming.

Settings

• Game Mode: Gamer 2 (after calibration)
• Brightness: Max

The SDR brightness is good. It gets bright enough to fight some glare in moderately-lit rooms, but visibility is a problem in sunny environments.

Settings

• Game Mode: Gamer 1
• Brightness: Max

The HDR brightness is okay. Although it's fairly bright and fights some glare, highlights don't pop at all. It also has inaccurate PQ EOTF tracking, with raised blacks in dark scenes and a slow roll-off before reaching its peak brightness. It's tone mapping before your source does, limiting how bright highlights get.

The gray uniformity is excellent. Colors are uniform throughout, although the edges are slightly darker. The uniformity is the same with 5% gray.

The black uniformity is disappointing. There's clouding throughout, and it lacks a local dimming feature to improve the uniformity.

The accuracy before calibration is okay. It doesn't have a dedicated sRGB mode, so colors are oversaturated. The gamma tracking is off, as most scenes are too bright. On the plus side, its color temperature is close to the 6500K target, and the white balance only has some minor inaccuracies. 

The accuracy after calibration is remarkable. Calibrating it fixes most issues, particularly with oversaturation and gamma tracking.

The monitor includes R/G/B and Six color hue and saturation settings to fine-tune your calibration.

This monitor has a fantastic SDR color gamut. It covers all of the sRGB color space used in most web content. It also displays a wide range of colors in the Adobe RGB color space, but reds are oversaturated and greens are undersaturated, although you may be able to fix this using a color-managed app.

The HDR color gamut is great. It has great coverage of the common DCI-P3 color space, with minimal inaccuracies, but it has more limited coverage of the wider Rec. 2020 color space.

The HDR color volume is decent. While it displays a wide range of colors, it fails to properly display dark and bright colors well, so HDR content looks muted.

The horizontal viewing angle is okay. It's fine if you need to share your screen with someone next to you, like for co-op gaming. However, the image gets darker and colors washout at wider angles.

The text clarity is decent. Using Windows ClearType (top photo) helps make text look bolder, but there are still some legibility issues. These photos are in Windows 10, and you can see them in Windows 11 with ClearType on and with ClearType off.

The direct reflection handling is good. The matte coating absorbs light well and spreads most out across the display, with minimal light reflecting off the screen.

The black levels rise a bit in bright rooms, and combined with the monitor's low native contrast ratio, blacks look gray in any environment.

This monitor has some distracting reflections in a bright room. Although the coating absorbs light well, the light spread out across the screen makes visibility an issue in sunny rooms.

Due to bandwidth limitations, you can only get the max refresh rate over HDMI with 8-bit signals, and not 10-bit.

Unlike other modern monitors, this one doesn't support HDMI Forum VRR.

The LG 24GS65F-B has good motion handling across its VRR range. The 'Fast' Response Time setting performs the best at most refresh rates, with only a bit of blur, but it has more inverse ghosting than 'Normal' and 'Off' at low refresh rates. The 'Faster' setting has such high CAD that it passes the limits of our chart, which you can see in an alternative graph.

The refresh rate compliance is good. While its response time isn't fast enough to make full-color transitions before the monitor draws the next frame, it's still faster than many other LCD displays.

The CAD at the max refresh rate of 180Hz is good. There's only a bit of blur with the 'Fast' Response Time setting and no noticeable inverse ghosting. The 'Off' and 'Normal' settings have more blur, while 'Faster' has distracting inverse ghosting.

The CAD at 120Hz is good. It performs similarly to its max refresh rate, as 'Fast' has less blur than 'Off' and 'Normal', and less inverse ghosting than 'Faster.'

When using a PC with an NVIDIA graphics card, a 120Hz signal isn't available through the NVIDIA Control Panel. We had to create a custom resolution to get 1080p @ 120Hz over DisplayPort for testing. That said, it is an available signal over HDMI, and we confirmed that creating a custom resolution has no impact on motion.

The CAD at 60Hz is decent. Unlike at higher refresh rates, the recommended Response Time setting is 'Normal' because it has less inverse ghosting than 'Fast.' That said, it's still fine if you want to leave it on 'Fast' to avoid changing settings in between games.

This monitor doesn't have a backlight strobing feature to reduce persistence blur.

This monitor has some VRR flicker in dark scenes and dark areas of bright scenes. It's noticeable, but not too distracting, either. However, it looks worse in person than in the video.

The monitor doesn't use pulse-width modulation to dim its backlight. There's still a slight increase in brightness that corresponds to the frame time, but this isn't the same as a full on-and-off flicker.

The LG 24GS65F-B has very low input lag for a responsive feel at any refresh rate.

To get downscaled 1440p @ 60Hz, you need to enable the console's HDMI override setting. As the Xbox Series X|S only supports HDR with 4k signals, you can't get HDR at all on this monitor.

Unlike other LG UltraGear monitors, this one doesn't supports DTS HeadphoneX.

Tested with: M2 MacBook Pro (Sequoia 15.6.1)

This monitor works fairly well with macOS, but there are some things to note. When using an HDMI connection, there's a rainbow-like effect and gray banding on the monitor's screen. However, this isn't the case when connected to the monitor over DisplayPort.

If you're using a MacBook with either connection, the 'Gamer 1' and 'RTS' Game Modes in HDR look closest to the laptop's display, but the monitor has a warmer color temperature. If you have the MacBook plugged into power, you can close the lid and continue using the monitor. However, without the MacBook plugged into power, the monitor goes into idle mode when you close the lid. When reopening the lid or waking the laptop up from sleep, windows return to their original positions.

The LG 24GS65F-B has a handful of extra features, including:

• Black Stabilizer: Adjusts the black level so that it's easier to see opponents in dark games.
• Crosshair: Adds a virtual crosshair that your game's anti-cheat tool won't detect.
• FPS Counter: Displays the current frame rate from your source.
• Reader Mode: Reduces blue light emitted from the monitor.

You can find the monitor's user manual on LG's product support page.
