Comparison – Hisense U8G Vs TCL 6 Series R646

Though both of these TVs are very similar and close market competitors, several comparisons can be drawn based on the following discussed basis’ that are important to know and understand before buying a TV for your home.

Style and Build

The design of Hisense U8G’s is very similar to the previous 2020 Hisense H9G model, except for some changes in the stand and the vents provided in the back of the TV. The stand is very solid that supports the TV well having a footprint of 55”. The back has tracks for cable management, along with removable clips that keep everything in place.

For TCL, it contains silver bottom bezel and the usual back panel, however, the stands have a different kind of look featuring new metal feel that don’t take up as much space as the previous ones, but with a little wobble. One great feature is the 3.5 inches distance from the table to the bottom of the screen, that lets you use your remotes and voice control easily and properly even with a soundbar placed in front of the screen. The back is build up of glossy plastic material, with textured bottom and textured sections of airflow.

Wall Mount Option

The Hisense U8G can be mounted on the walls easily saving some surface space, as there are clips on the back of TV which can be removed for wall mounting.
The TCL series 6 R646 isn’t quite practical for mounting on the wall since it has two bottom parts near the inputs sticking out, and is also very bulky in comparison to Hisense.


The Hisense U8G has the native contrast of 5279:1 while the TCL series 6 R646 has the native contrast of 8,542:1. What this means is that both of these TV’s offer outstanding contrasts, and deliver deep blacks. The TCL series has a higher local dimming feature that adds much more life to the image displayed.

Black levels

In terms of black levels, these are extremely deep and inky in terms of the TCL series 6 R646, posing an extremely strong proposition value whether you’re playing games or watching high quality animated videos. Users have said that the black levels are better in the TCL series 6 R646 as compared to Hisense U8G, as it shows more blooming than the TCL TV.


Though not the best but satisfactory enough for a lot of people, the Hisense U8G has a low input lag of 60 Hz, which is basically good for activities like gaming. But, this cannot be considered the best in the market, as input lag of 120 Hz monitors are also available in the market.

In comparison to the previous TCL 6 Series R635 2020 QLED model, the input lag was seen to have significantly improved in the R646 model, with no observed delays during gaming. However, some issues might be in the VRR Input lag, due to the active HDMI Forum VRR to users.

User Interface

Hisense U8G’s user interface is seen to have been upgraded to Android 10, with the surfing experience and navigation getting easier and faster. This new interface resembles Google TV Interface on 2021 Sony TVs, with slight differences. In case of TCL 6 Series R646, it comes with a Google TV, making it pretty different from the Hisense and Sony TVs. But, people have complained a few about the tough navigation that you only get used to over time and several bugs in the system.

Picture Quality

Besides contrast (which we have mentioned already), the SDR Brightness, HDR Brightness, and local dimming are some of the key features that affect the picture quality. Both of these TVs offer excellent brightness and are not affected by factors like glare with small highlights and details standing out pretty good. The TCL R646 even has a mini LED backlighting providin great experience.

The HDR brightness in both of these TVs are also pretty great, making highlights standing out very great. One difference however, is that the Hisense U8G doesn’t follow EOTF nicely, that will end up making some scenes brighter than necessary. The TCL Series 6 R646, however, has EOTF following the target PQ curve perfectly, making sure you don’t lose too much details when watching bright scenes.

Viewing Angle

Like any other VA-Type TV, the image is somewhat degraded and distorted when viewed at a certain angle, with the most noticeable being the ‘gamma effect’, where the images appear washed out. This was the case for the Hisense U8G TV. Similar is the case for TCL 6 Series R646, with distorted and degraded image qualities whenever viewed at an angle, since it also uses the VA-Type panel.

Sound Quality

The Hisense U8G has decent enough distortion and frequency response. Even though, some audible harmonic distortion at high volumes and an almost zero low bass or thump, producing absolutely no thump or rumble, it definitely has a well-balanced sound profile and can get pretty loud on necessity.

The TCL Series 6 R646, on the other hand, also has a good enough bass able to get louder with a bit higher deviation. Regarding distortion though, there is absolutely no distortion even at very high maximum volume.


The factors affecting motion of a TV the most is the response time, which was seen overall better on TCL 6 Series R646 TV. Although, sometimes there are slow transitions seen, there’s overshoot in transitions overall, but these are common for VA panels.

In case of the Hisense U8G, the results were also satisfactory with issues like dark scenes transitions being extremely delayed, that will even make you see ghostings behind objects, which is basically called the black smear.
