The Acer GN246HL is a decent 1080p gaming monitor. It has a TN panel with decent picture quality when viewed from directly in front, but the viewing angles are very narrow so even at a slight angle the image looks washed out. It is also possible to flicker the backlight to clear up fast motion for gamers, but it doesn't support more advanced features like FreeSync.

Our Verdict

6.5 Mixed Usage

The Acer GN246HL is a decent monitor for mixed usage. The Acer GN246HLBbid is best suited for casual gaming. The lack of ergonomic features and poor viewing angle make it an okay choice for office use. It has a poor contrast ratio and poor black uniformity, and is best suited for a medium lit room without much glare.

Pros
  • 144Hz refresh rate feels smooth
  • Excellent response time
Cons
  • Picture deteriorates rapidly when viewed at an angle
  • Blacks are gray and blotchy when viewed in a dark room
6.5 Office

Decent monitor for office usage. The native resolution and size are basic, many people will want a larger or higher resolution monitor. It has very limited ergonomic options, and it doesn't swivel or rotate so the screen can't easily be shared with neighbours.

7.1 Gaming

Decent monitor for casual gaming. The high refresh rate helps motion look smooth. It has great low input lag, but it is higher than similar 144 Hz monitors. It doesn't support any adaptive sync technologies like AMD's Freesync. Late-night gaming isn't as enjoyable due to the limited contrast and poor black uniformity.

6.4 Multimedia

Decent choice for multimedia use. Watching movies or TV shows on Netflix or YouTube will look good, but the 1080p resolution will be limiting to some users. Dark room performance isn't great with the limited contrast and poor black uniformity. The viewing angle is disappointing, so it isn't great for sharing clips with other people.

6.3 Media Creation

Decent monitor for media creation. The 1080p resolution and the lack of ergonomic options might be limiting to some. The poor coverage of the professional Adobe RGB color space makes it less than ideal for professional users. Picture quality is decent, but the dark room performance isn't great and blacks are never truly black.

4.9 HDR Gaming

HDR is not supported. For HDR gaming, there aren't a lot of choices. The Samsung CHG70 is a good choice.

The design of the Acer GN246HL is basic with a good build quality. It's entirely made of plastic and does not feel high-end or look stylish. The stand supports the monitor well and there is no provision for cable management. Adjustment options are only limited to tilt, which can make it hard to position it into a comfortable viewing position or to rotate it for sharing. It is a very thin and lightweight monitor, allowing mobile professionals to set up an office pretty much anywhere.

The gray uniformity is good. Little clouding is noticeable and on the 50% gray picture. The image looks darker towards the upper side in the photo. This is the result of the narrow viewing angles, which causes different sides of the screen to appear slightly different colors. However, this should not cause any issues when browsing the web or watching YouTube.

The black uniformity of the Acer GN246HLBbid is poor. Backlight bleed is evident all over the screen; any dark video content, or dark video game scenes when viewed in a dark room will not look good and black will look more like gray. However, if the monitor is used in brighter rooms such as an office where the dark content is more rare, this will not be an issue.

Out of the box, the accuracy of the Acer GN246HLBbid monitor is decent when the picture mode is set to 'User'. The color temperature is a little warmer than our desired 6500K.

The monitor is missing a lot of blue in the lighter grayscale shade, whereas white balance dE is slightly higher than our 3.0 level, above which we expect most people to start noticing it. Finally gamma, is not far from our 2.2 target, but this is mainly due to the fact that the monitor is brighter in lower input signal values and darker in higher ones

The color accuracy of the monitor is a bit off at 3.1. For some people this might be noticeable.

The Acer GN246HL uses PWM to reduce the backlight, and there is flicker at all brightness levels.

There is an optional BFI mode that reduces the flicker frequency to improve motion with 3D content. This feature uses NVIDIA's 3D Lightboost technology. It is possible to modify the system to use this technology all the time. BlurBusters.com has an excellent article that covers how to activate BFI on a Lightboost monitor.

When activated there is a significant change to the color temperature (it is too warm) and this can't be changed. The contrast slider becomes 42 by default, and when raised colors are clipped. Since the BFI mode turns the backlight off for longer periods of time the overall brightness of the screen is significantly reduced to 121 cd/m². The contrast ratio is also reduced to 786 due to the change in colors and contrast slider. The contrast can be adjusted in BFI mode but causes more clipping.

Input lag was measured with DVI instead of HDMI, as the native 144 Hz refresh rate is only possible over DL-DVI.

Input lag is higher than most 144Hz monitors, but still very good. Non-native resolutions are supported, but the native 144 Hz refresh rate is only supported at 1080p. When selecting a non-native resolution, the graphics card will usually upscale the image to the native resolution, so most people won't notice this.

The HDMI port can only output at 60 Hz, unless a custom resolution is used in which case it can reach 76 Hz. RGB full range is not detected properly over an HDMI cable, so it is better to use RGB limited or YCbCr 4:4:4.

There is a TRS audio out jack that can be used to output audio to an external speaker or headphones. It works best with an amplified device as the output doesn't get very loud.

The Acer GN246HL does not have built-in speakers, but there is an audio out jack that can be used to send sound to headphones or a speaker system. This is not very useful as audio can only be transmitted over HDMI, and this monitor does not support 144 Hz over HDMI.

The monitor uses NVIDIA's Lightboost technology, which when combined with NVIDIA's 3D Vision Kit can be used to display 3D images by flickering the backlight in sync with 3D glasses. It is also possible to enable the backlight flicker with normal content, as explained in the Image Flicker section.

There is an array of 5 controls on the bottom right of the screen, plus the power button. The buttons aren't labelled, but they are mapped to OSD commands that are displayed on screen. The controls aren't very intuitive and can be difficult to get used to. The buttons themselves don't travel very much and it isn't easy to tell when you actually pressed the button.

Differences Between Sizes And Variants

We tested the Acer GN246HL, which is a 24" 1080p TN monitor. It is also available in 27" (Acer GN276HL), and for the most part, we expect our review to be valid for both.

If someone comes across a different type of panel or if their monitor doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Acer GN246HL is a basic 1080p monitor. It is decent for mixed usage, but there are better monitors in the same price range. See our recommendations for the best 144 Hz monitors, the best PC gaming monitors, and the best budget gaming monitors.

ASUS VG248QE

The ASUS VG248QE is significantly better than the Acer GN246HL. The ASUS VG248QE has better ergonomics allowing you to place it as you like, and also has lower input lag, and better response time so it's much better for gaming. The faster response time creates a smaller image trail that is good for fast action gaming.

BenQ Zowie XL2411P

The BenQ Zowie XL2411P is much better than the Acer GN246HL. The XL2411P has much better ergonomics, and a flicker-free backlight. The GN246HL has a faster response time, but there is noticeable overshoot, causing distracting ghosting artifacts behind fast-moving objects. The XL2411P has lower input lag, ensuring a responsive gaming experience, even when gaming at 60Hz, great for console gamers.

LG 24GL600F

The LG 24GL600F is a bit better than the Acer GN246HL for most uses, and is a lot better for gaming. The 24GL600F supports FreeSync variable refresh rate technology, for a nearly tear-free gaming experience. The LG also has a flicker-free backlight, so there are no duplications in motion, and it has an optional black frame insertion feature. Finally, the LG has a higher refresh rate and slightly lower input lag.

Acer XF251Q

The Acer XF251Q is much better than the Acer GN246HL. The GN246HL has a faster 144Hz refresh rate, but it doesn't support any variable refresh rate technologies like FreeSync or G-SYNC. The XF251Q has a 75 Hz refresh rate, but it supports FreeSync. The Acer GN246HL uses PWM to dim the backlight, and this causes flicker that may bother some people, whereas the XF251Q is flicker-free. Finally, the XF251Q has much less input lag, especially when gaming at 60Hz.

Acer G257HU/G7 Series

The Acer G257HU is better than the Acer GN246HL. They both deliver similar overall picture quality, but the G257HU has wider viewing angles. The G257HU has a flicker-free backlight. The Acer GN246HL has a higher refresh rate and better response time, great for gaming.

HP Pavilion 22CWA

If you will be watching the monitor from the side, the IPS panel of the HP 22CWA is a better choice as it has better viewing angles than the Acer GN246HL that has a TN panel. The HP has also better gray uniformity which improves picture quality, whereas the Acer has somewhat better motion blur and marginally better refresh rate, which is important to gamers.

Dell P2417H

If you plan to do collaborative work, then the Dell P2417H is a better choice due to better viewing angles. On the other hand, the Acer GN246HL is a better choice if you sit right in front of the screen in a brighter room. The Dell P2417H has significantly better ergonomics that allow you to place it as you like. The Dell P2417H has better input lag and thus is more responsive which is great for gaming. The Acer GN246HL, on the other hand, is slightly brighter and has a faster response time with less blur and a better refresh rate of 144Hz.

Dell U2515H

The Dell U2515H is more suitable for a room with wide seating. On the other hand, the Acer GN246HL is a very fast monitor with very good motion features. The Dell U2515H has better viewing angles and significantly better ergonomics so you can position it to your liking. Also, it has a higher resolution and marginally larger size, giving you more detail to work on. The Dell U2515H also has slightly lower input lag which is great for gaming.
