The LG 48 C1 OLED and the Gigabyte M32U are very different displays with different target audiences. The LG is a large TV we tested as a monitor that has an OLED panel. The OLED panel delivers a nearly instantaneous response time, with wide viewing angles and perfect blacks. The large screen isn't meant to be used as a desktop monitor, though, and there's a risk of permanent burn-in. Although the Gigabyte doesn't perform as well overall, it's a more traditional form factor that fits on most desks, and there's no chance of burn-in.
The build quality is good. It's entirely plastic, with no metal components, though the plastic seems to be of decent quality. There's a little bit of flex on the back panel, but otherwise, it's fairly solid.
When we first tested the monitor, we noted no consistent issues with noise. However, after using the monitor extensively since our initial test, it now produces several added noises. When black frame insertion (BFI) is on, the monitor has a pulsating coil-whine-type noise. Additionally, when the monitor operates between 120–144Hz it produces a consistent hum/buzz. The monitor is also loud when the brightness is between 30 and 70 in some modes.
The ergonomics are good. It has a good swivel and great tilt range, making it easy to share your screen with another person. Additionally, its height adjustment is outstanding, so you can adjust it to your preferred position. However, it doesn't rotate, and you can't use it in portrait mode for reading long documents or put two monitors side by side in a vertical dual-screen setup. The stand features a loop for cable management. If you want something with even better ergonomics, check out the Dell U3223QE.
The contrast is mediocre, and deep blacks look gray next to bright highlights in a dark room. While the monitor has local dimming, it doesn't improve the contrast. If you want a 4k monitor with much better contrast, look into the Samsung Odyssey Neo G7 S32BG75.
Unfortunately, although the Gigabyte M32U has a local dimming feature, it's terrible. In most real content, the local dimming feature doesn't activate. The monitor is edge-lit, with approximately 16 large dimming zones, so when local dimming does activate, the transitions are very noticeable and distracting.
Enabling the Local Dimming feature locks out a few settings. It enables DCR, which negatively impacts scene brightness accuracy and locks the brightness at maximum.
The SDR brightness is very good, and it gets bright enough to fight glare in most environments. Different content causes some variation in peak brightness, and the monitor dims very small highlights slightly, but most content doesn't show noticeable dimming.
These results are from after calibration in the 'Custom 1' Picture mode with the Brightness at its max and Local Dimming enabled. If you want something brighter, then check out the Dell G3223Q.
The HDR brightness is okay, though small highlights are dimmer and won't pop. There's a sharp cut-off at the peak brightness, but this means that the monitor doesn't tone map before your computer does. However, much of the image is slightly less bright than it should be, and very dark scenes are over-brightened. If you care about HDR brightness, then check out the Cooler Master Tempest GP27U, which gets much brighter in HDR.
These results are with HDR and Local Dimming 'On.'
The Gigabyte M32U monitor has a decent horizontal viewing angle. While you can still share your screen with someone else, the image appears slightly washed out at wider angles.
The monitor has a very good vertical viewing angle, so the image is consistent if you stand up and look down at the monitor.
The Gigabyte M32U has unremarkable black uniformity. There's quite a bit of cloudiness throughout the screen, and significant backlight bleed along the top and bottom edge when local dimming is off. Local dimming reduces backlight bleed and cloudiness away from some brighter content, though it worsens black uniformity.
The accuracy before calibration in the sRGB mode is excellent, and it follows the sRGB curve fairly well. The white balance is great, and the color temperature is fairly close to the calibration target. The monitor slightly oversaturates red, but there are no significant issues with any color.
Unfortunately, using the 'sRGB' Picture Mode setting locks other settings, including Contrast and Dynamic Contrast Ratio. So, if you want to use those settings, you need to change Picture Mode to 'Custom 1,' which delivers the second-best results but worse overall performance, as you can see here.
The accuracy after calibration is exceptional. White balance and colors are nearly perfect, and any remaining inaccuracies aren't noticeable. After calibration, you can use any of the settings that are locked out in sRGB mode.
The SDR color gamut is fantastic. It can display the entire sRGB color space most current desktop and web content uses. However, it has only decent coverage of the Adobe RGB color space. It also has significant issues displaying greens accurately in Adobe RGB, which isn't ideal for professional publishing.
The HDR color gamut is good. It has good coverage and tone mapping in the DCI-P3 color space used by most current HDR content, though worse coverage in the Rec. 2020 color space.
This monitor has HDMI 2.1 bandwidth, so both DisplayPort and HDMI provide the same speeds and capabilities. Your card must support Display Screen Compression to reach these maximum speeds over DisplayPort or HDMI.
This monitor supports FreeSync and is G-SYNC compatible over HDMI and DisplayPort. It also supports HDMI Forum VRR.

This monitor supports backlight strobing to reduce persistence blur. The first time we enabled the feature with VRR, the backlight strobing continued to function as low as 10Hz, but below 55Hz, it flickers in multiples of the framerate. Unfortunately, the backlight kept fluctuating and was borderline unusable, as shown in this slow motion video filmed between 54 and 55Hz (Note: This video contains rapid, bright flashing). The effect is not that noticeable in real life, and we created the video to demonstrate the effect, not how it appears.
After experiencing this issue, we power cycled the monitor and restarted the PC, and the BFI feature behaved more like the other Gigabyte monitors we tested. Below 85Hz, the backlight stops strobing, and there are no distracting backlight fluctuations.
The Gigabyte M32U has low input lag, so you won't notice any delay and get a responsive feel. It's important to ensure the firmware on the monitor is F06 or newer, as there's an issue with input lag with previous versions of the firmware.
The Gigabyte M32U works well with the PS5. However, since its HDMI ports require Display Stream Compression (DSC) to support certain features, the PS5 is limited to 4:2:0 when gaming at 4k @ 120Hz, as the PS5 doesn't fully support DSC. If you prefer something that supports the full HDMI 2.1 bandwidth with the PS5, check out the LG 32GQ950-B instead.
The Gigabyte M32U works well with the Xbox Series X|S. While you can enable 1440p @ 60Hz with the Xbox Series X|S, you need to adjust the setting that turns off VRR and HDR, so you should leave it at 1440p @ 120Hz with VRR enabled.
The Gigabyte M32U has two HDMI 2.1 ports, making it a great choice for someone who has a console and an HDMI 2.1 graphics card.
The monitor has a USB-C port and supports a few advanced USB-C features, including DisplayPort Alt Mode and 15W fast charging for supported devices. However, the power delivery feature doesn't deliver enough power to recharge most laptops while in use; if you want a monitor with similar performance and greater power delivery over USB-C, you can look into the Lenovo Legion Y32p-30.
The M32U's USB-C port allows you to use the monitor as a KVM (keyboard, video, and mouse) switch, so you can view and control two sources with a single set of input devices, which is great if you're working from home and want to use a business and personal computer at the same desk.
The Gigabyte M32U has a few extra features, including:
It also supports Picture-in-Picture or Picture-by-Picture, allowing you to display two sources simultaneously, though this feature isn't available in HDR or if FreeSync is enabled.
