The manufacturers claim that these TVs of the same model but with different screen size are identical. The test of TCL 65R617 vs TCL 55R617 provides an opportunity to compare such units to confirm or deny this statement.
When comparing TCL 55R617 vs TCL 65R617 from the position of the picture quality, the slightest difference wasn’t noted. Both units feature FALD CCZ tech that provides perfect contrast ratio. They demonstrate good screen uniformity without dead pixels.
The units can’t boast good viewing angles. When looking at the screen on the center, the picture is flawless. If going near 30 degrees in either direction, the colors become blurring. So it may be a problem when more than three people watch TV so that wider angles are required.
TVs’ 120hz CMI motion interpolation (soap opera effect) can be deactivated for real 120Hz versus many other models in this price range that will be only 60Hz. The TVs come with a built-in tuner to use an antenna, and it’s possible to pause and rewind up to 90 minutes of live TV and electronic program guide.
The units aren’t Bluetooth capable, but it’s easy to hook it up to the external audio source via HDMI ARC, digital optical audio out, or an analog audio out (3.5 mm jack). Note that the ARC HDMI supports both video and audio to use it as the sole connection to an AVR.
The TVs’ audio is decent and it features good loudness for a small room. However, the built-in speakers aren’t able to produce enough bass that’s why an amp would be desirable.
When examining the TCL 55R617 vs 65R617, no diversities in their design have been found. They’re flat and feature a stable metal stand that requires a wide desk. However, the legs are reversible to reduce the stand’s width. The TVs’ borders are also metal with the silver finish. They’re quite thin like the TVs themselves. The units come with two big vents to prevent overheating.
