Samsung CHG70 Review: The great hope. A Gaming Monitor with High Dynamic Range (HDR), Quantum Dot Technology, WQHD, a VA Panel and Freesync 2.




Pretty much a big part of the gaming community will have been waiting for the CHG70 with the first time a combination of a high refresh rate panel with 144 Hz, a WQHD (2560x1440) resolution, quantum dot technology, Freesync 2 technology, High Dynamic Range (HDR), and a VA panel. A great hope, and finally I was able to test it full of anticipation. HDR sounds quite tempting, but I was never convinced that HDR would work properly with a brightness of 500 cd / m2. But maybe this looks different in monitors? No matter what, with 144 Hz you have a flawlessly smooth gaming experience. In-depth details and measurements like the OSD, black equalizer etc, you will find in the video and in the article. Let's take a closer look. 

IMPORTANT(!) Updates and new information about the Samsung CHG70 can be found at the bottom of the article or in the table of contents (if available). Also available within the forum (click here).

Measurement data

Contrast, Brightness and Black Point:


Second measurement with local dimming under PERFECT conditions, which will never occur in games. A panel with native 3000: 1 will be better here:

For the Freesync overclocking you need the program "ToastyX Custom Resolution Utility" (CRU) which you can download here.

Samsung CHG70 Review

Overall Rating: 7.7/10 (77%)

The rating strongly depends on the price of a monitor in a specific region or country. Consider, an overall rating is only a guide value and my personal overall impression. It does not mean that a monitor with a 95% monitor suits better for your needs than a monitor with a 70% rating(!). 



Overall the Samsung C32HG70 is a good monitor with its own disadvantages as almost all monitors on the market. It has wonderful Quantum Dot colors, a very good response time for a VA panel, very good blacks, a good homogeneity, and a very good structured OSD with an easy and simple navigation. This is definitely a good gaming monitor. Still, the C32HG70 also has its issues like the low Freesync 2 range, text inversion issues, horizontal scan lines, and huge high dynamic range issues on the PC. While on a console, in theory, it works very good. The problem, however, is, that 8 dimming zones and a brightness of around 500 cd/m2 are not enough for HDR in my opinion. Take a look at the forum for the C32HG70 review and firmware updates, optimal settings & more.


Pros & Cons



- Backlight strobing feature (worse to Nvidia G-Sync's ULMB, better than the Eizo's/LG's solution)
- Better VA viewing angles and less VA glow compared to the HP Omen X35 and even the Samsung CFG70
- Good contrast (2022:1), but not the stated 3000:1 from Samsung
- Easy OSD overview & 3 own profiles with macro buttons
- Very good blacks (consider the VA glow)
- Very good colors
- Good homogeneity (no clouding or backlight bleed)
- Good build quality
- Very good response time, especially for a VA panel monitor
- Low input lag
- USB Hub, 2 x USB 3.0



- Half matte panel coating
- Freesync has a very low range from 80-120 Hz on Ultimate Engine and 90-120 Hz on Standard Engine. With the Custom Resolution Utility from ToastyX, you can improve the max. Freesync Range to 80-120 Hz)



- Not really flicker-free (PWM)
- Footstand takes a lot(!) of space on your desk
- Clearly visible horizontal scan lines (on my unit more at the left quarter of the monitor)
- Text Inversion (Text sharpness)
- HDR currently is useless on the PC. On the PS4 it works fine. Dark image content still does not look as good and we miss many details in blacks at brighter image content. Even if you brighten your gamma, your colors and the image quality will suffer
- Local dimming is pretty useless (only 8 dimming zones)
- pretty pricey for a monitor without G-Sync
