What experts liked
Very easy set up thanks to Roku software. Screen offers sharp, detailed quality and deep contrast. Plenty of hook up options including three HDMI ports, Ethernet, and USB.
- BestReviews
The obvious advantage TCL has here is its full array panel and several dozen contrast control zones - they help each scene obtain higher contrast and even help SDR content look its best.

It has excellent black levels, high brightness, and punchy HDR picture
- Digital Trends
Input lag is the amount of time it takes for a display to update after receiving a signal, and this is one of the few areas in which the 55R617 scores well. The HDTV showed an input lag of 18.4ms is almost half of most screens we test, though it has very high input lag in its Movie picture mode.

The Roku operating system is very easy to use.

The excellent Roku streaming service and menu is built-in to the TV. Overall it’s easy to navigate, has a bunch of 4K HDR options via an app, and the UI is responsive and customizable.

HDR performance is very effective.
- Consumer Reports
The 6-Series 55-inch TCL Roku television is great looking. Right out of the box, I really like the slim bezels and the feet.

The new design is so much better than last year’s plain black plastic, with the slimmer bezels and stealth metal design. It truly looks like it belongs in a modern living room, and stands toe to toe with other major brands in this department.
- Display Lag
The TCL remote app performed the task of a distant remote and cast the TV’s audio to my smartphone.

What experts didn't like
Difficult to view at any angle beyond 45 degrees. Top and bottom of screen is a bit dark.
- BestReviews
Where there’s room for improvement here is with how the TV handles motion. For the most part, it’s surprisingly good - even if you’re watching fast-paced content - but the way Roku TV is implemented here, you don’t have much control over how motion is handled. There are just three settings - high, medium, low - or it can be turned off entirely.

Vertical banding is visible in some units.
- Digital Trends
No headphone in remote jack.
- PCVerge
The other issues were related to control of the 96-zone full-array backlight, with the brightness of the entire screen occasionally jumping up and down by a noticeable amount.

All that said, there is a drawback with the TCL 55R617 and it's viewing angles. Sitting even a little off axis starts to affect color and contrast.

Power hog. Only three HDMI ports. No headphone jack in remote.
- PC Magazine
The panel is good, but not great.

Needs separate Roku app to optimize picture.
- Consumer Reports
The only connector lacking is the number of HDMI ports. The 6-Series only has 3 and I would love to have 4 or 5.
- Hipster Pixel

Motion blur. While TCL did add a mode called LED Motion Clarity, which adds black frame insertion during content, this option drastically reduces your peak backlight brightness, and causes a noticeable flicker that is quite distracting.
- Display Lag
There appeared some clouding around the moving objects on the screen.
