The Samsung CRG9 is a good ultrawide monitor with an impressive amount of screen real estate, great for multitasking. It has outstanding peak brightness, even with HDR content, and it has great reflection handling, making it a good choice for a bright room. The CRG9 is also a great choice for PC gaming, as it has outstanding motion handling, excellent low input lag, and it supports FreeSync. Unfortunately, like most VA monitors, the image degrades when viewed at an angle, and due to the size of the monitor, it has somewhat limited ergonomics.

Our Verdict

7.7 Mixed Usage

Overall, the Samsung CRG9 is a good monitor for most uses. It delivers a great gaming experience, even in HDR, with excellent low input lag and outstanding motion handling. For office use or media creation, the large, high-resolution screen is excellent for multitasking. Unfortunately, the image degrades at an angle, and due to the large size of the display, it has limited ergonomics.

  • Excellent peak brightness.
  • Outstanding screen real estate for multitasking.
  • Image degrades when viewed at an angle.
  • Limited ergonomics due to the monitor's size.
7.5 Office

Overall, the Samsung CRG90 is a decent office monitor. The wide, high-resolution screen is great for multitasking, and it supports picture-by-picture. It also has excellent peak brightness and great reflection handling, so glare shouldn't be an issue. Unfortunately, the image degrades when viewed at an angle, and due to the large display, it has limited ergonomics.

8.0 Gaming

This is a great monitor for gaming. It has outstanding motion handling with an impressive response time, resulting in very clear motion. It also has excellent low input lag at its native refresh rate, and it supports FreeSync, but only over DisplayPort. Unfortunately, the image degrades at an angle, so it isn't as good for co-op gaming.

7.7 Multimedia

Good monitor for multimedia. The huge screen delivers an impressive movie experience, but it has only a decent contrast ratio and bad black uniformity, so it isn't great in a dark room. It has great reflection handling, though, and excellent peak brightness, so glare isn't an issue in a bright room. Unfortunately, the image degrades at an angle, so it isn't as well-suited for watching with a group of friends.

7.8 Media Creation

The Samsung CRG90 is a good monitor for media creation. It has a huge amount of screen real estate, so you can spend more time creating, and less time scrolling and zooming. Unfortunately, the image degrades at an angle, and due to the large size it has limited ergonomics, so it isn't a good choice for sharing the screen with clients or coworkers.

7.2 HDR Gaming

Decent monitor for HDR gaming. It has excellent low input lag, great peak brightness in HDR, and the impressive resolution and size deliver a more immersive gaming experience. Unfortunately, it has only decent contrast, an ineffective local dimming feature, and bad black uniformity, so it doesn't look great in a dark room.

The stand is quite a bit smaller than the CHG90. It supports the monitor well but doesn't completely prevent it from wobbling.

Height Adjustment
4.7" (11.9 cm)
Switch Portrait/Landscape No
Swivel Range -15° to 15°
Tilt Range -15° to 2.5°

Update 08/09/2019: There was a mistake in our swivel range scoring. The ergonomics score has increased slightly.

The stand has a decent height adjustment range, but a very limited swivel range and disappointing tilt range. Given the size of this monitor, it obviously can't rotate to portrait orientation.

Wall Mount VESA 100x100

The back of the monitor is quite plain but looks good. There is a ring around the back of the stand mount that can light up, as shown here. Cable management is handled by a hole in the stand, and there's a headphone hook that can fold down from the back of the stand, which is a nice touch that is fairly uncommon.

There is no quick release on the stand, but it can be VESA mounted. VESA mounting requires a special adapter (included).

0.5" (1.3 cm)

The borders are thin on three sides, and look good.

Thickness (with stand)
13.8" (35.1 cm)
Thickness (without stand)
7.6" (19.3 cm)

Due to the curvature of the screen and the extreme width of this monitor, it's quite thick, even when VESA mounted.

Build Quality

The overall build quality is great. Not much has changed from the CHG90; it's still a solid, well-built monitor that should last for years.

Native Contrast
2262 : 1
Contrast With Local Dimming

The Samsung CRG9 has a decent contrast ratio. It's quite a bit lower than last year's model, which is a bit disappointing. The local dimming feature improves the contrast a bit, but not enough to make a noticeable difference.

Picture Quality
Local Dimming
Local Dimming

The local dimming feature is very similar to the CHG90 and CHG70. It's edge-lit, with only 10 dimming zones, so it doesn't have very tight control over the dimming areas. In some HDR scenes, though, it does help to boost the peak brightness of the display. There is an automatic mode for the local dimming, and it automatically engages local dimming with HDR content and disengages in it SDR.

The Samsung CRG90 has excellent peak brightness and is one of the brightest monitors we've tested. It's significantly brighter than the CHG90 and the Dell U4919DW. There is some variation in brightness with different content, which may be distracting in some cases. With local dimming disabled, the peak brightness in SDR is limited to about 620 cd/m².

Great HDR peak brightness; again, one of the brightest on the market, and significantly brighter than the CHG90. Small specular highlights in some scenes are extremely bright. With local dimming disabled, the CRG90 isn't able to boost the backlight as high, and the peak brightness is 640 cd/m² with any content.

Out of the box, the CRG9 has decent accuracy. Gamma doesn't follow the sRGB target curve at all. The strange dip at the top of the curve is unusual, but isn't unheard of, as we saw something similar with the Acer XF251Q. The color temperature is a bit warm, and there are noticeable inaccuracies in almost all colors.

These results were obtained with the default settings of the 'RTS' Picture Mode, but with the gamma set to 'Mode 3', which was the most accurate setting out of the box.

The Samsung C49RG9 has an outstanding response time, much better than the Dell U4919DW and the CHG90. With the recommended 'Faster' overdrive setting, there is almost no noticeable overshoot in any transition. The 'Fastest' setting has a slightly faster 80% transition time, but there is more overshoot, resulting in a slower overall transition time.

The Samsung CRG90 has an excellent 120Hz refresh rate, and it supports FreeSync 2. There are two FreeSync modes, and we recommend the 'Ultimate Engine' mode, which has the widest FreeSync range and supports low framerate compensation (LFC). This might not work with all games, though, in which case the 'Standard Engine' should work, but it has a worse FreeSync range of 70 to 120 fps. Unfortunately, this monitor only supports FreeSync over DisplayPort.

Black Frame Insertion (BFI)

The Samsung CRG90 has excellent low input lag at the native refresh rate, or in FreeSync mode. Unfortunately, when it isn't at 120Hz the input lag is noticeably higher, including in HDR, which was tested at 100Hz, as we were only able to send HDR at 100Hz. Due to the bandwidth limitations of DisplayPort 1.4, with the high native resolution it isn't possible to send 10-bit colors at 120Hz, so HDR is only supported at 100Hz or a lower resolution.

Unlike the CHG90, there is no Mini DisplayPort connection. Instead, there is an additional DisplayPort 1.4 port. There is a 3.5mm Microphone In port, which acts as a passthrough, and the Microphone Out port must be connected to a PC for it to work. There is also a headphone jack, and the volume can be controlled through the monitor's OSD.

Additional Features
RGB Illumination
Fixed (On/Off)
HDR10 Yes
Multiple Input Display

There are very few additional features on this monitor. It doesn't have internal speakers, but it does support HDR10. It supports Picture-by-Picture (PBP), allowing you to work with two sources on the screen at once, but unlike the Dell U4919DW, there is only one upstream USB connection, so you'll have to either buy a separate keyboard and mouse switch or have two sets (see our recommendations for the best gaming mice and the best wireless mice). For gaming, there is an option to add a virtual crosshair to any game.

On-Screen Display (OSD)

The controls are identical to those found on the CHG90. There is a joystick control that is used to navigate the OSD, and it works very well. There are also three buttons that allow you to switch between different settings presets.

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

The Samsung CRG9 is an impressive ultrawide monitor, but unless you're specifically looking for a monitor with this aspect ratio, there are better options out there. See our recommendations for the best ultrawide gaming monitors, the best gaming monitor size, the best curved gaming monitors, and the best large monitors. See also our recommendations for the best mice and the best keyboards.

Samsung C49HG90/CHG90

The Samsung CRG9 is a bit better than the Samsung C49HG90/CHG90. The CRG9 has a higher resolution screen, flicker-free backlight, and a faster response time. The CHG90 has a slightly higher refresh rate, but this doesn't add much.

Dell U4919DW

The Samsung CRG9 is a bit better than the Dell U4919DW, depending on your needs. The CRG9 has much better gaming performance, with a faster refresh rate, better response time, and support for FreeSync variable refresh rate, and the CRG9 supports HDR. The U4919DW has better viewing angles and might be a bit better for office use for some people, as it can connect to two displays at once with a single keyboard and mouse.

LG 49WL95C-W

Although they use different panel technologies, the Samsung C49RG9/CRG9 is slightly better than the LG 49WL95C-W for most uses, and is much better for gaming. The LG has better viewing angles, which might be better in some cases, but the Samsung is significantly brighter, especially in HDR, and it has a better contrast ratio. The CRG9 is also much better than the LG for gaming, as it has a faster refresh rate, much faster response time, lower input lag, and it supports FreeSync.


The Samsung C49RG9/CRG9 and the ASUS TUF VG27AQ are very different monitors. The Samsung has a 32:9 aspect ratio, which is twice the size of the ASUS. The ASUS performs better overall, as it has an IPS panel with wider viewing angles, and it has better ergonomics as well as a faster response time. Also, the ASUS has a 165Hz refresh rate compared to Samsung's 120Hz,  but the Samsung's VA panel has a higher native contrast ratio and better reflection handling.

Philips Momentum 436M6VBPAB

The Samsung CRG9 is better than the Philips Momentum 436M6VBPAB. The CRG9 has better ergonomics, better gray uniformity, and better reflection handling. The CRG9 is also much better for gaming, as it has a faster refresh rate, lower input lag, and slightly better motion handling. Although both monitors use VA panels, the Philips Momentum 436M6VBPAB looks better in a dark room, as it has much better contrast and better black uniformity.

Dell U3818DW

The Dell U3818DW and the Samsung CRG9 are similar, but due to the differences in panel technology, they each have their advantages and disadvantages. The U3818DW uses an IPS panel, which delivers wider viewing angles, and the Dell has better ergonomics. The CRG9 has a much larger, higher resolution screen, and is a much better gaming monitor. The CRG9 supports HDR, has a faster refresh rate, and much better motion handling.


The Samsung C49RG9/CRG9 is much better overall than the AOC CQ32G1. The Samsung has a 5120x1440 resolution, it has better ergonomics, it gets much brighter, supports HDR, and has a quicker response time. On the other hand, the AOC has a 144Hz refresh rate, a better contrast ratio, wider viewing angles, and much better out-of-the-box color accuracy.
