The Dell G3223Q is Dell's first 4k gaming monitor with a 144Hz refresh rate and HDMI 2.1 bandwidth. It's 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, 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 an edge-lit local dimming feature, too, but it only works in HDR.
The Dell G3223Q is great overall. It's an excellent gaming monitor thanks to its 144Hz refresh rate, HDMI 2.1 bandwidth, and quick response time for smooth motion handling. It also has low input lag and variable refresh rate support to reduce screen tearing. It's impressive for the office and excellent for content creators with its 4k resolution and large screen, and the remarkable out-of-the-box accuracy means you don't need to get it calibrated. It's very good for watching multimedia content with a few friends since it has wide viewing angles, but it's only decent for HDR because it has a low contrast and a terrible local dimming feature.
The Dell G3223Q is impressive for office use. The large 4k screen delivers clear text, and there's enough space to open multiple windows at once. It also has okay ergonomics and wide viewing angles, making it easy to share the screen with someone next to you. You won't have issues using it in a bright room either as it gets bright enough to fight glare and has good reflection handling.
The Dell G3223Q is excellent for gaming. It has a high 144Hz refresh rate with a 4k resolution and HDMI 2.1 bandwidth, meaning you can play high-frame-rate games from consoles or a PC without issue. It also has a quick response time across its entire refresh rate range, and there's VRR support to reduce screen tearing. Sadly, it isn't good for dark room gaming because it has a low contrast that makes blacks look gray, and even if it has a local dimming feature, it performs terribly and only turns on with HDR games.
The Dell G3223Q is very good for watching multimedia content. The 4k resolution allows you to watch your favorite 4k movies and shows, and the 32 inch screen provides an immersive viewing experience. It's good for viewing in bright rooms with a few friends because it has good reflection handling, and the wide viewing angles mean that everyone sees an accurate image. However, it doesn't perform well in dark rooms because blacks look gray and the local dimming feature is terrible, and it only turns on in HDR.
The Dell G3223Q is excellent for content creators. The 4k resolution and 32 inch screen help deliver sharp images and you can see more of your work area at once. It also displays a wide range of colors in SDR and the out-of-the-box accuracy is simply remarkable, meaning you don't need to get it calibrated. The okay ergonomics and wide viewing angles also make it easy to share the screen with a client next to you as you can turn the screen and see the same image from the side.
The Dell G3223Q is decent for HDR. It has a wide HDR color gamut with good peak brightness to make some highlights stand out. Unfortunately, blacks look gray in the dark due to the low contrast, and even if it has a local dimming feature that automatically turns on in HDR, it performs terribly, as it doesn't improve the contrast or make small objects stand out.
We tested the 32 inch Dell G3223Q, and the results only apply to this variant. It's the only 4k monitor part of Dell's G Series gaming lineup, and you can see the differences between each monitor below. Dell has other 32 inch 4k monitors available too, like the Dell S3221QS and the Dell U3223QE, but they're part of different lineups.

The Dell G3223Q and the Gigabyte M32U are both excellent 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 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.
The Dell G3223Q is better than the Gigabyte M32UC for most users. The Dell has a faster response time, resulting in much clearer motion, especially in dark scenes. The Dell also has much better viewing angles, so the image looks the same even if you're not sitting directly in front. If you're in a dark room, though, the Gigabyte is a better choice, as it has a much higher contrast ratio, resulting in darker, more uniform blacks.
The Gigabyte M28U and the Dell G3223Q are very similar monitors, with the big difference being that the Dell has a larger screen. Besides that, they each have a 4k resolution with a 144Hz refresh rate, VRR support, and HDMI 2.1 bandwidth, and you won't have issues playing games from consoles on them. The Dell displays a wider HDR color gamut, but it has worse tone mapping anyways, so colors in HDR look better on the Gigabyte. They each have smooth motion handling, but the Gigabyte has a backlight strobing feature, which the Dell doesn't have.
The LG 27GP950-B and the Dell G3223Q are similar 4k monitors with 144Hz refresh rates, but there are a few differences. The Dell has much better reflection handling, so it's a better choice for well-lit rooms, and it has much better out-of-the-box accuracy. They each display a wide color gamut in HDR, but the LG has much better tone mapping so colors look better. The main difference between them is that the LG supports 48 Gbps bandwidth of HDMI 2.1, while the Dell has 24 Gbps, so the LG doesn't require compression for high-frame-rate signals.
The Samsung Odyssey G7 S28AG70 and the Dell G3223Q are both excellent gaming monitors. Overall picture quality is a bit better on the Dell because it gets brighter and has better reflection handling, so it's a better choice for well-lit rooms. Also, it has much better out-of-the-box accuracy and quicker response times, especially at lower refresh rates. However, the Samsung has better ergonomics because you can swivel it, and it supports higher HDMI 2.1 bandwidth, meaning your graphics card doesn't need compression for high-frame-rate signals.
The Dell G3223Q is a bit better than the Sony INZONE M9. The Dell has a wider range of ergonomics, so it's easier to place it in an ideal viewing position. The Dell also has much better accuracy out of the box, as colors aren't oversaturated, and there are no noticeable issues. Finally, the Dell model offers better build quality, as there are a few issues with the construction of the Sony monitor's stand, and there have been reports of quality control issues with the Sony model.
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 okay ergonomics as you can adjust it any way you like it except rotate into portrait mode. However, it has a narrow swivel range and limited height range, meaning it's a bit harder to place in an ideal position compared to other monitors. 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.
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.
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:
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.
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:
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 over-saturated in Adobe.
The Dell G3223Q has an excellent HDR color gamut as it displays 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, meaning it isn't future-proof because more content will come out in that color space.
The Dell G3223Q has an amazing HDR color volume. It displays bright colors well, but it's limited by the incomplete color gamut and 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 good reflection handling. Although reflections from strong light sources can get distracting, it has high enough peak brightness to fight glare and you won't have any issues with it unless you place it opposite a really bright light source.
The Dell G3223Q has a fast refresh rate that you can achieve with HDMI 2.1 graphics card that support Display Stream Compression, but since all HDMI 2.1 graphics cards support compression, you won't have any issues.
Although NVIDIA doesn't certify the Dell G3223Q as G-SYNC compatible, it still works over its entire refresh rate range with HDMI and DisplayPort connections. FreeSync also works over both inputs.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The Dell G3223Q has a very fast response time at its max refresh rate. Motion looks smooth with the 'Fast' Response Time setting, which performs the best because 'Super Fast' and 'Extreme' each have slower total response times with more overshoot, leading to inverse ghosting.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The response time at 120Hz is excellent, meaning motion looks smooth when playing console games at 120 fps. Like with its max refresh rate, the 'Fast' Response Time setting has the quickest overall response time with the least amount of overshoot.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The Dell G3223Q has a good response time at 60Hz. It's slower than at higher refresh rates, meaning you see more motion blur, but it's still good. There's also some overshoot in dark transitions, which causes a bit of inverse ghosting. Once again, the 'Fast' setting performs the best, which means you can leave it on that setting and not worry about changing it if the frame rate of your game drops.
The Dell G3223Q doesn't have a backlight strobing feature to reduce persistence blur.
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.
The Dell G3223Q has a Console Mode that doesn't have any issues playing games from the PS5, thanks to the HDMI 2.1 bandwidth. As the monitor 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. This makes text clarity a bit worse, but it doesn't affect the gameplay experience. The monitor's Source Tone Map feature that tone maps in HDR according to the game.
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.
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 where 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:
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.
