Absolutely no problems with reflections

The biggest weakness of these two TVs

Both TVs have a quite narrow viewing angle. There are noticeable changes in black levels and a shift in colors, so you only get a good picture when you are sitting straight in front of the TV. This also means that these TVs are not recommended if you plan to watch the TV with the whole family or have a wide seating area.

The same HDR formats

As you can quickly see, the two TVs are incredibly similar. This is because both use a VA panel and are equipped with Full Array Local Dimming. Therefore, both TVs have deep and inky blacks and a great HDR performance.

Another thing they have in common are the supported HDR formats. These would be HLG, HDR10 and both dynamic formats HDR10+ and Dolby Vision.

Mini vs Direct LED

Although the R646 has a mini LED backlight, the Hisense U8G has the better Dimming Algorithm resulting in less blooming and better backlight control in real life content. 

Furthermore, both TVs have stereo speakers. These speakers are nothing too special, but they serve their purpose. However, the bass is quite weak, so the atmosphere is somewhat lost — but that is usually the case with flatscreen TVs. In addition, both support Dolby Atmos and DTS Audio codecs.

Both TVs have their pros and cons when it comes to use in a home theater environment. 

The Hisense TV has a lower contrast ratio and displays content a little brighter than it should be. However, it has a great peak brightness of 1600 nits, which means that bright highlights do really pop in an impressive way. Nevertheless, the R646 does an excellent job in this regard as well.

Gaming performance Comparison

Excellent for gaming

Both TVs are excellent for Gaming and have nearly the same features due to the HDMI 2.1 ports. They have a Variable Refresh Rate, an Auto Low Latency Mode and support [email protected]. The combination of a low input lag and good motion handling allow for a responsive gaming experience. The only thing they lack for Xbox gaming is Dolby Vision in [email protected] It does work up until 60fps though

Gamers with a Playstation 5 don’t really see any differences in the gaming performance. Only when using certain PCs without FreeSync for gaming the Hisense TV has the slight edge cause a variable refresh rate via G-Sync is also supported. But this is a very specific use case

Smooth motion handling - Limited viewing angle

The motion handling is really good in both TVs and there is only very little motion blur in fast movements. This is due to the fast response time of around 4ms, that both TVs have in common.

Here you only have to pay attention to the very limited viewing angle again, if you want to watch with the whole sports club on the TV, for example.

Android 10 gegen Google TV

Another difference can be found in the smart operating system of the TVs. The Hisense U8G uses Android 10 and the R646 uses Google TV. However, this is more of a cosmetic difference because the Google TV OS is the Android OS with just another name and design.

Our conclusion:
Raw HDR power vs higher peak brightness

tvfindr Vitus
Vitus // tvfindr.com

No matter which of the two TVs you choose, you’ll get great performance for a comparatively low price. As you can see, both TVs are quite similar in most regards, but there are some minor differences, that could have impact on your buying decision.

If you want to have the raw HDR power the R646 might be the better choice. Even though its backlight control is not as good, it can display dark content a little better, making it the more suitable all round TV.

The higher peak brightness of the U8G is good, but the R646 can compensate this advantage by the higher contrast ratio and the more accurate displaying of the contents brightness.

With real content these differences are not as visible though and Hisense has a better dimming algorithm, so unless you’re specifically looking for a TV with G-Sync you can also get whichever is cheaper for you!
