CHG90 vs. CRG9 vs. Odyssey G9

Samsung has three 49” super ultrawide curved gaming monitors that are currently available. So, which of one of the CHG90, CRG9 or Odyssey G9 models provides the best experience when it comes to playing games?

You can find out in this comparison guide for these Samsung monitors.

Quick Summary

When compared to the Samsung CHG90 and Samsung CRG9, the Samsung Odyssey G9 features a more pronounced screen curvature. The Odyssey G9 also has the highest maximum refresh rate in addition to having the best performance out of this group of 49” gaming monitors when it comes to input lag and HDR brightness levels.

The Samsung CHG90 has the best contrast ratio and is the only one of the three to support Mini DisplayPort 1.4 as well as Variable Refresh Rate over HDMI. With that said, the CHG90 does struggle with input lag in native resolution at 60 Hz in addition to having the lowest SDR and HDR brightness levels. It also has the lowest maximum resolution.

The CRG9 easily has the best brightness levels when displaying SDR content and comes really close to matching HDR brightness performance of the Odyssey G9. Unlike the other two monitors, however, it does not support G-SYNC.

Aspect Ratio

All three screens have an aspect ratio of 32:9.

Curve Radius

When it comes to the curve radius, the CHG90 and CRG9 monitors have the same 1800R curvature.

On the other hand, the Odyssey G9 has a more pronounced curvature at 1000R.

The extra curvature of the Samsung Odyssey G9 means that you won’t have to move your head around as much when compared to the flatter Samsung CHG90 and Samsung Odyssey G9 screens.

Maximum Refresh Rate

The Odyssey G9 has the highest maximum refresh rate out of this group, followed by the CHG90. The CRG9 is the lowest when it comes to max frame rate.

You can check out the maximum refresh rates for the three gaming monitors below:

  • CHG90: 144 Hz
  • CRG9: 120 Hz
  • Odyssey G9: 240 Hz

Maximum Resolution

The Odyssey G9 and CRG9 are tied with having the highest maximum resolution. The CHG90 offers the lowest resolution of the three products in this versus showdown.

You can find the maximum resolutions below:

  • CHG90: 3840 x 1080
  • CRG9: 5120 x 1440
  • Odyssey G9: 5120 x 1440

Inputs

When it comes to inputs, the CHG90 comes with two HDMI ports in addition to a DisplayPort and a Mini DisplayPort.

The CRG9 and Odyssey G9 each comes with a pair of DisplayPorts in addition to one HDMI port.

You can find a breakdown of the port versions for the three screens below:

CHG90:

  • 1x DisplayPort 1.4
  • 1x Mini DisplayPort 1.4
  • 2x HDMI 2.0

CRG9:

  • 2x DisplayPort 1.4
  • 1x HDMI 2.0

Odyssey G9:

  • 2x DisplayPort 1.4
  • 1x HDMI 2.0

FreeSync/Variable Refresh Rate Inputs

The CHG90 support FreeSync and Variable Refresh Rate through both the DisplayPort and HDMI port.

With the CRG9 and Odyssey G9, FreeSync and VRR are limited to only the Display Port.

G-SYNC

Both the CHG90 and Odyssey G9 have been certified to support G-SYNC, a feature for NVIDIA graphics card that functions in the same way as FreeSync and Variable Refresh Rate. On the other hand, the CRG9 does not support this feature.

The FreeSync, G-SYNC and Variable Refresh Rate features provide adaptive sync, which helps make the action look smoother in motion in addition to eliminating any potential screen tearing for games that don’t run at a consistent frame rate.

Input Lag

According to RTINGS, the input latencies for all three monitors are generally excellent. With that said, there seems to be an issue with playing games in native resolution at the 60 Hz with the CHG90.

Overall, the Odyssey G9 performs the best when it comes to having the lowest input lag as it beats out the other two monitors at native resolution and with variable refresh rate enabled.

With that said the CRG9 has a slightly lower input lag when playing at native resolution in 60 Hz.

You can take a look at RTINGS’ input lag test results for the CHG90, CRG9 and Odyssey G9 below:

Native Resolution Input Lag

  • CHG90: 4.6 ms
  • CRG9: 4.9 ms
  • Odyssey G9: 2.1 ms

Native Resolution at 60 Hz Input Lag

  • CHG90: 42.1 ms
  • CRG9: 21.6 ms
  • Odyssey G9: 22.5 ms

Variable Refresh Rate Input Lag

  • CHG90: 4.6 ms
  • CRG9: 5.7 ms
  • Odyssey G9: 2.2 ms

Contrast Levels

According to RTINGS, the CHG90 has the best contrast ratio out of this group with or without local dimming enabled. As a result, it is better at displaying deeper black colors when compared to the other two monitors.

You can find RTINGS’ contrast level tests results for the three CHG90, CRG9 and Odyssey G9 displays below:

Native Contrast Ratio

  • CHG90: 3756:1
  • CRG9: 2262:1
  • Odyssey G9: 2231:1

Contrast Ratio with Local Dimming

  • CHG90: 3756:1
  • CRG9: 2359:1
  • Odyssey G9: 2320:1

Brightness Levels

When it comes to SDR brightness, the CRG9 is the clear winner as it can get quite a bit brighter when compared to the other two screens.

The Odyssey G9 edges the CHG90 as the former has a brighter SDR real scene brightness level in addition to being more consistent.

You can take a look at RTINGS’ test results for the SDR brightness levels of the CHG90, CRG9 and Odyssey G9 below:

When it comes to HDR brightness levels, the Samsung Odyssey G9 barely edges out the Samsung CRG9.

While the CRG9 has a higher real scene HDR brightness level, the Odyssey G9 perform better in various peak and sustained windows tested by RTINGS. With that said, you will be getting a great HDR experience with either of these two monitors.

On the other hand, the CHG90 brightness levels of the CHG90 are too dimmed to truly bring out the advantages of HDR.
