Overview
TCL 55S551G is a 55 inch 4K UHD LED television running Google TV, with a 60Hz panel and the usual mix of HDMI, USB, Wi-Fi, Bluetooth and RF inputs for cord cutters and streamers alike.
The S5 series sits at the value end of TCL's lineup, built around Google TV rather than TCL's own Fire TV variant, so the interface leans on Google's cast and voice search tools. A 60Hz refresh rate keeps it suited to everyday viewing and casual gaming rather than fast motion sports or high frame rate console titles.
