The Dell G3223Q is Dell's first 4k gaming monitor with a 144Hz refresh rate and HDMI 2.1 bandwidth. It has a 32-inch display and is currently the only 4k monitor in Dell's G Series gaming lineup. It has a Console Mode that allows you to play 4k games up to 120 fps from the PS5 and Xbox Series X thanks to the HDMI 2.1 bandwidth. It also has native FreeSync variable refresh rate (VRR) support to reduce screen tearing, and the G-SYNC compatibility mode works on it, too, even if NVIDIA doesn't certify it. It has a few extra features, like a dedicated sRGB mode if you need accurate colors, and there's also an edge-lit local dimming feature, but it only works in HDR.
We buy and test more than 30 monitors each year, with units that we buy completely on our own, without any 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 and custom tools to measure various aspects with objective data-based results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance against the competition, and whether or not it's easy to find.
Our Verdict
The Dell G3223Q is decent for PC gaming. While it has a 144Hz refresh rate that's good enough for most gamers, it isn't ideal for competitive gaming. It also has good motion handling across its VRR range, but it still has motion blur. Its input lag is low enough for a responsive feel at high refresh rates, but it increases at 60Hz, which is disappointing for playing reaction-based games. Unfortunately, it delivers limited picture quality because it has a low contrast ratio that makes blacks look gray, and it has a terrible local dimming feature that causes blooming.

Popular Monitor Comparisons
The Dell G3223Q is a decent 4k monitor for PC gaming that has features like HDMI 2.1 bandwidth and VRR support, so it's also a great choice for console gaming. It also has remarkable color accuracy, which is great if you care about accurate images or want to do some photo editing on the side. That said, it has increased input lag at 60Hz, which is disappointing for playing reaction-based games, and you can get better value with a more reliable option like the Gigabyte M32U.
Also, see our recommendations for the best 4k 144Hz monitors, the best PS5/PS5 Pro monitors, and the best monitors for Xbox Series X.
The Dell G3223Q and the Gigabyte M32U are both decent 4k gaming monitors. They're very similar overall as they each have a 144Hz refresh rate, HDMI 2.1 bandwidth, and a quick response time, but the Gigabyte has a backlight strobing feature, which the Dell doesn't have. However, the Dell gets brighter, so it's better for well-lit rooms, and the out-of-the-box accuracy is much better, too.
The Dell U3223QE and the Dell G3223Q are different types of 4k, 32-inch monitors. The G3223Q is a gaming monitor with a much higher refresh rate, VRR support, and quick response times, while the U3223QE is an office monitor with much better ergonomics and a bigger selection of inputs. Besides the different features, they have similar picture quality, but the G3223Q has much better reflection handling.
The Dell G3223Q and the LG 32GR93U-B are both good 4k, 144Hz gaming monitors. They perform very similarly, but the LG has a slight advantage when gaming at 60Hz as it has a faster response time and lower input lag. The Dell has a more accurate sRGB mode, but the LG is still accurate regardless. Besides that, both monitors are very similar, and you'll be happy with either.
The Dell G3223Q and the Samsung Odyssey Neo G7 S32BG75 are both excellent gaming monitors with different panel types with strengths and weaknesses. The overall picture quality is better on the Samsung as it delivers deeper blacks with much better local dimming and makes smaller highlights pop more in HDR. However, the Dell is better for co-op gaming thanks to its wide viewing angles. If you care about image accuracy, the Dell has much better out-of-the-box accuracy and better motion handling with high-frame-rate signals.
Test Results
The Dell G3223Q has a rather simplistic design with a silver and black body. It also has blue backlighting around the hinge in the back that you can turn on and off.
The build quality is great. It's well put together, and there aren't any obvious flaws. It's entirely plastic, which feels solid and only flexes a bit in the back. The hinge on the stand is sturdy and supports the monitor well. Overall, it feels better built than other plastic monitors.
The Dell G3223Q has good ergonomics, as you can adjust it any way you like it except rotate into portrait mode. There's a cutout in the stand for cable management to help keep your setup clean.
The stand has a large base that takes up a good amount of space, and because the top is a bit slanted, it's hard to place stuff on it. The stand also supports the screen well, as there's minimal wobble.
The joystick helps you navigate the on-screen menu, and you can customize three of the buttons to shortcuts if you want to quickly change a setting or switch inputs. There's a power button on the bottom right side. If you want a monitor you can control via a remote control, consider the Samsung Odyssey G70D S32DG70.

The Dell G3223Q has a low native contrast ratio, meaning blacks look gray in the dark. Even with local dimming on, the contrast is worse because all the dimming zones turn on. If you want a similar display with better dark room performance, check out the Gigabyte M32UC instead.
The Dell G3223Q has an edge-lit local dimming feature, and it's terrible. It automatically turns on in the 'DisplayHDR 600' Picture Mode, and you can't disable it, but you can use other HDR modes if you don't want to use it. There are eight large dimming zones, and they're all on at the same time with most content, so it's not actually doing anything, and the contrast is worse than in SDR. If there's content that forces a zone to turn off, like with the test pattern, then the uniformity between zones is awful and distracting. Also, the algorithm is slow, and it struggles to keep up with fast-moving objects.
If you're looking for a monitor with a much better local dimming system, take a look at the BenQ MOBIUZ EX321UX.
The SDR peak brightness is great. Scenes are consistently bright enough to fight glare, but small highlights on dark backgrounds don't pop much. These results are from the 'Custom Color' Picture Mode after calibration with the Brightness at its max.
The HDR brightness is good as long as you have the monitor updated to the latest firmware and you're using the 'Custom Color HDR' Smart HDR mode. Firmware version M3T103 added this mode in Smart HDR, and it gets brighter than 'DisplayHDR 600,' which is what we originally used for testing. After the update, 'DisplayHDR 600' has a Real Scene brightness of 524 cd/m² with most test windows around 615–660 cd/m², and it has frame dimming with 2% highlights. Overall, using 'Custom Color HDR' results in brighter highlights, including smaller ones that stand out more.
The monitor follows the target PQ EOTF curve well if you enable Source Tone Map in Console Mode, but there's a sharp cut-off at the peak brightness, leading to a loss of fine details in bright scenes. The EOTF is also similar in 'DisplayHDR 600' with Source Tone Map on. Disabling Source Tone Map leads to a slower roll-off, preserving details, but the roll-off also happens sooner, which means some scenes aren't as bright as intended. You can see the EOTF with Source Tone Map disabled in 'Custom Color HDR' here.
The horizontal viewing angle is decent. It's good enough for sharing your screen with someone sitting next to you, as the image remains accurate from the sides.
The Dell G3223Q has a good vertical viewing angle. Besides a bit of color washout and brightness lost, the image remains accurate when viewing from below, which is good if you want to eye-mount the display above eye level.
The Dell G3223Q has very good overall gray uniformity. The edges are a bit darker, which you'll notice if you have a full-screen webpage or document open, but there's very little dirty screen effect in the center.
There's a uniformity compensation setting available in the 'Creator' Picture Mode only, and it raises the black level to hide any uniformity issues on the sides. The contrast is worse because of this, but the overall brightness doesn't change. You can see the uniformity results from it here:
- Score: 8.4
- Photo
- 50% Std. Dev.: 3.872%
- 50% DSE: 0.125%
There are reports of users experiencing bad temporary image retention. We tested it to see if there's noticeable image retention, and even if it shows signs of it, it's minor and disappears quickly. If you notice bad image retention, let us know.
| Time (Minutes) | Photo | Retention |

The black uniformity is mediocre. The screen looks blue due to the low contrast, but there's no blooming around bright objects with local dimming off. In HDR with local dimming on, the edges of the screen are darker, but there's a lot more blooming.
There's a uniformity compensation setting available in the 'Creator' Picture Mode, and it raises the black level. With it enabled in SDR, the contrast is even worse, and you can't enable it in HDR. You can see the uniformity results from it here:
- Score: 5.8
- Photo
- Native Std. Dev.: 1.772%
The out-of-the-box accuracy on the Dell G3223Q is remarkable. You can access the sRGB mode in the 'Creator' Picture Mode by selecting 'sRGB.' The Dell G3223Q does an incredible job at clamping the colors to the sRGB color space, and the colors, white balance, color temperature, and gamma are all extremely accurate. The sRGB mode only locks the Hue, Saturation, Gain, and Offset settings, so you can still adjust the brightness and other settings. There are other picture modes where you can adjust these settings, but they're less accurate, and colors are over-saturated.
The accuracy after calibration is incredible, but it isn't that much improved from before calibration. The main advantage of getting it calibrated is that you can control the few settings that are locked in the sRGB mode.
The Dell G3223Q has a fantastic SDR color gamut. It has perfect coverage of the sRGB color space used in most web content, and it has great coverage of the Adobe RGB color space used in some photo editing programs. However, some colors, like red, are oversaturated in Adobe.
The Dell G3223Q has an excellent HDR color gamut, displaying a wide range of colors in the commonly used DCI-P3 color space. Using the 'Custom Color HDR' Smart HDR mode after firmware update M3T103 results in much better tone mapping than 'DisplayHDR 600,' meaning it preserves details better with saturated colors. However, it still has disappointing coverage of the wider Rec. 2020 color space, so it isn't future-proof because more content will come out in that color space.
The Dell G3223Q has a great HDR color volume. It displays some bright colors well, but it's limited by the low contrast ratio. It's much better if you use the 'Custom Color HDR' mode instead of 'DisplayHDR 600,' but you need to update the firmware to M3T103 to have access to the 'Custom Color HDR' mode.
The Dell G3223Q has fantastic text clarity thanks to the high pixel density. Enabling Windows ClearType (top photo) makes the letters bolder and easier to read.
The direct reflection handling is mediocre. While the matte coating spreads light out, it still has mirror-like reflections.
This monitor does an excellent job of maintaining consistent black levels in a bright room. That said, blacks still look gray due to the low contrast ratio.
There's a lot of light reflected off the screen on this monitor. This can be distracting if you place it in front of a bright light source or sunny window.
The Dell G3223Q has incredible gradient handling, and you won't notice any banding with shades of similar colors.
The Dell G3223Q has a fast refresh rate that you can achieve with an HDMI 2.1 graphics card that supports Display Stream Compression, but since all HDMI 2.1 graphics cards support compression, you won't have any issues.
| NVIDIA | VRR Min | VRR Max |
| DisplayPort | <20Hz | 144Hz |
| HDMI | <20Hz | 144Hz |
| AMD | VRR Min | VRR Max |
| DisplayPort | <20Hz | 144Hz |
| HDMI | <20Hz | 144Hz |
Thanks to its HDMI 2.1 bandwidth, the monitor also supports HDMI Forum VRR.

The Dell G3223Q has good motion handling across its refresh rate range with VRR enabled. Although the 'Super Fast' Response Time setting has the lowest CAD at the max refresh rate, the 'Fast' setting is consistently the best across the entire range. That said, there's more inverse ghosting at lower refresh rates.
The refresh rate compliance is mediocre. Its response time isn't fast enough to keep up with changing frame rates, even at 60Hz.

| Fast | Heatmap | Chart | Photo |
| Super Fast | Heatmap | Chart | Photo |
| Extreme | Heatmap | Chart | Photo |
The CAD at the max refresh rate of 144Hz is good. Although the 'Super Fast' Response Time setting has more overshoot than 'Fast,' it still has lower CAD and sharper motion, but 'Extreme' has too much overshoot, causing inverse ghosting.
| Overdrive Mode | CAD Heatmap | RT Chart | Pursuit Photo |
| Fast | Heatmap | Chart | Photo |
| Super Fast | Heatmap | Chart | Photo |
| Extreme | Heatmap | Chart | Photo |
The Dell G3223Q has good CAD at 120Hz. Unlike at its max refresh rate, the recommended overdrive setting is 'Fast' because 'Super Fast' and 'Extreme' have too much overshoot, causing inverse ghosting. This means you may have to change the setting if the frame rate of your game drops or if you change games.
The Dell G3223Q doesn't have a backlight strobing feature to reduce persistence blur.
The Dell G3223Q has minimal VRR flicker with changing frame rates, which is fantastic for gaming.
The Dell G3223Q uses a completely flicker-free backlight at all brightness levels, which helps reduce eye strain and image duplications.
The Dell G3223Q has low input lag for a responsive gaming experience with high-frame rate games. Sadly, it increases a lot more with 60Hz games, and while it's still fine enough for casual console gamers, it's still worse than other monitors at 60Hz.
As the Dell G3223Q is limited to 24 Gbps of bandwidth instead of the full 48 Gbps of HDMI 2.1, it displays chroma 4:2:0 instead of 4:2:2 because the PS5 doesn't support compression, but it doesn't affect the gameplay experience. The monitor has a Source Tone Map feature that tone maps in HDR according to the game.
The Dell G3223Q displays all signals from the Xbox Series X as long as it's in Console Mode. Keep in mind that the Xbox doesn't support HDR with 1080p or 1440p signals, so this isn't a limitation of the monitor.
As the Dell G3223Q's HDMI 2.1 bandwidth is limited to 24 Gbps, your graphics card needs to use compression for signals that require a higher bandwidth, like 4k @ 120Hz.
You can use the two USB ports to plug in peripherals like your mouse and keyboard as long as you connect the USB-B cable to your computer. While the Dell G3223Q doesn't have a USB-C hub, if you're looking for a monitor that does, you may want to consider the Lenovo Legion Y32p-30.
The Dell G3223Q works well with recent MacBooks, as VRR and HDR work, but there are some connection issues. At times, windows go back to the MacBook screen when waking up from sleep, but there are times when they stay in place. Also, sometimes, it simply loses the connection after you put the MacBook to sleep, so you need to unplug and reconnect.
The Dell G3223Q has a few extra features, including:
- Color space: You can choose either the 'DCI-P3' or the 'sRGB' color space in the 'Creator' Picture Mode.
- Console mode: Provides the best compatibility with the PS5 and Xbox Series X.
- Dark stabilizer: Adjusts the gamma so you can see opponents better in dark games.
- Display alignment: Displays a virtual grid, making it easy to line up the display next to another.
- FPS counter: Shows your current frame rate.
- RGB Illumination: There's blue backlighting that you can turn on and off, but you can't change the color. Updating the firmware to version M3T103 lets you turn it off, as before that, it was always on.
- Timer: Displays a timer on the screen.
- Uniformity compensation: Meant to provide better screen uniformity, but it just raises the black levels.
The Picture-in-Picture and Picture-by-Picture modes also allow you to view images from two sources at once, but you're limited to a 60Hz refresh rate while using it, even after firmware update M3T103.
