TCL 5-Series S555 65" (QLED) vs TCL Q6 50"

The Verdict

Both TCL QLED options deliver solid value, but they target different viewing scenarios. The 5-Series S555 65-inch commands a $270 premium by offering significantly larger screen real estate, superior brightness at 800 nits versus 600 nits, and gaming features that matter: 120Hz refresh rate with 8ms input lag and VRR support make it responsive for console and PC gaming. The 4K resolution and HDR support (Dolby Vision, HDR10+) are identical. Audio remains modest on both models with 2.0 channels, neither supporting Dolby Atmos. The Q6 50-inch compensates with reasonable pricing and adequate specs for general viewing: 60Hz refresh rate, 14ms input lag without VRR, and sufficient brightness for most rooms. Connectivity slightly favors the larger model with Wi-Fi 6 versus Wi-Fi 5, though both include Google TV and modern features. The Q6's compact 50-inch footprint suits smaller rooms or secondary displays. Choose the 5-Series S555 if you have space and gaming is priority; the picture quality gap is meaningful at brightness levels. Select the Q6 50-inch for budget-conscious buyers in confined spaces or as a secondary television where gaming performance matters less.
