The TCL 65-Inch Class S5 UHD 4K LED Smart TV with Fire TV (65S551F, 2024) targets a value-focused 65-inch 4K upgrade, but still brings wide HDR support via HDR PRO+ (Dolby Vision, HDR10+, HDR10, and HLG). Its bright LED backlight helps the picture hold up better in sunnier rooms, and it leans into streaming and smart-home convenience with built-in Fire TV, hands-free Alexa control, and Apple AirPlay 2. Gaming also gets meaningful attention with 120Hz VRR support (Game Accelerator 120) and ALLM for reduced input lag.
Key takeaways
- 4K detail boost: The 65-inch 4K UHD panel delivers a clear jump in detail for textures, UI elements, and small text compared with 1080p.
- Broad HDR format support: HDR PRO+ covers Dolby Vision, HDR10+, HDR10, and HLG, giving broad app/format compatibility with brighter highlights and fuller color.
- Smoother motion and better gaming feel: Motion and gaming perks include Motion Rate 240 with MEMC, plus Game Accelerator 120 with VRR and Auto Game Mode (ALLM) for smoother play and less lag.
- Streaming-first Fire TV experience: Built-in Fire TV keeps streaming apps and live TV in one place, though reports mention occasional menu slowdown that may improve after clearing storage, trimming unused apps, or rebooting.
- Audio features with some variability: Audio support includes Dolby Atmos, DTS Virtual:X, and Enhanced Dialogue Mode, but results can differ by app. Remote responsiveness complaints come up often, so keeping the TV updated—and using a simple external streamer if speed becomes a sticking point—can help.
Budget-Friendly 65-Inch 4K Upgrade with Strong HDR
The TCL 65-inch S5 is a smart step up for anyone wanting a big 4K screen without paying premium prices. The 4K UltraHD panel brings 4X the resolution of 1080p, so fine textures and small on-screen text look cleaner.
HDR PRO+ support covers Dolby Vision, HDR10+, HDR10, and HLG, which helps compatible movies and shows land with better highlight detail and richer color. A High Brightness LED Backlight keeps the picture punchy in brighter rooms, and the bezel-less FullView 360 metal design looks modern on a stand or wall.
How I’d size it up vs other Fire TV options
I’d compare it alongside the Insignia 55-inch Fire TV, the bigger Insignia 75-inch QLED Fire TV, or add a streamer like Fire TV Stick 4K or Fire TV Cube.

Gaming and Motion Performance
How I dial in smooth motion and low-lag play
Motion handling stays sharp thanks to Motion Rate 240 with MEMC frame insertion. I use it for sports and fast action because it tightens blur and keeps pans cleaner. Some scenes can look slightly “video-like” with MEMC, so I keep it moderate for movies and raise it for live games.
Gaming feels snappy for the money. Game Accelerator 120 enables up to 120 Hz VRR support, and Auto Game Mode (ALLM) kicks in automatically to cut input lag and keep frame delivery steady. I’ve also seen multiple customers say it doubles well as a gaming monitor, especially at this price point, which matches my experience for casual to competitive play.
Here’s how I set it up for best results:
- Turn on ALLM so the TV switches into game settings without extra steps.
- Enable VRR when a console or PC supports it to reduce tearing and stutter.
- Use MEMC mainly for sports; dial it down for films to avoid the soap-opera effect.
- If I want a dedicated streamer, I pair it with a Fire TV Stick 4K Plus for fast app performance.

Fire TV Features: Convenient, Sometimes Laggy
Fire TV keeps streaming, live TV, and recent apps in one place, so I spend less time hunting for inputs. Setup feels quick, and I can treat it as a clean upgrade from an older set.
Some owners report occasional menu lag with built-in Fire TV; I usually fix it by trimming background apps and keeping storage free.
Alexa built-in adds hands-free control for search, volume, and smart-home routines, and Apple AirPlay 2 works as a nice extra for casting from iPhone, iPad, or Mac.
If I want a snappier interface, I pair a stick like this Fire TV Stick 4K Plus or step up to the Fire TV Cube. Check current pricing and availability at Amazon here!

Built-In Audio: Good for Casual Use, Mixed by App
What I get in real use
I get a broader soundstage than I expect from TV speakers, since Dolby Atmos and DTS Virtual:X add a virtual 3D effect. Enhanced Dialogue Mode helps voices cut through music and effects, so I miss fewer lines in shows and games.
App behavior can vary, though. Some apps sound punchy, while others shift volume or spacing, so I keep the remote handy and re-check settings after installing new apps.
For a speaker-free setup, I pair this TV with a Fire TV Cube, or I step up visuals with an Insignia 55-inch Fire TV. Check current pricing and availability at Amazon here!

Common Complaint: Remote Control Issues
The biggest drawback I see repeated is the remote. Some units feel unresponsive, and a few owners even report it works only about 30% of the time. That kind of hit-or-miss control can spoil an otherwise strong value play, especially if I use voice less and rely on quick button taps.
What I do to reduce remote headaches
I use a few practical steps to separate setup hiccups from actual hardware faults:
- I replace the batteries first, even if they’re “new,” and I reseat them to fix loose contact.
- I re-pair the remote in settings, then restart the TV to clear stuck Bluetooth states.
- I check line-of-sight and interference. Nearby soundbars, consoles, and routers can crowd the signal.
- I confirm the TV firmware is current, since input lag sometimes improves after updates.
- I keep voice control as a fallback. Pairing with a hands-free Fire TV Cube can reduce remote dependency.
If I still get frequent misses, I treat it as a warranty-level issue. For a smoother control experience, I sometimes steer people to a stick-based setup like the Fire TV Stick 4K Plus or a larger integrated option like the Insignia 55-inch Fire TV.

TCL 65S551F (2024) hits a sweet spot for a 65-inch living-room TV with real feature depth. I look for 4K UHD first, then I confirm the HDR stack. This set’s HDR PRO+ support covers Dolby Vision, HDR10+, HDR10, and HLG, so I can expect strong compatibility across apps, discs, and live streams.
Search terms I use to buy smart
I keep these keywords handy because they surface the right listings and filter out older panels:
- “TCL 65S551F 2024 65-inch 4K UHD”
- “Dolby Vision + HDR10+ TV”
- “Game Accelerator 120” and “120 Hz VRR + ALLM”

How I match specs to real setups
I pair 120 Hz VRR and ALLM with consoles for cleaner input response. For streaming upgrades, I compare add-ons like Fire TV Stick 4K Plus or a hands-free hub such as Fire TV Cube. For size alternatives, I reference Insignia 55-inch Fire TV and Insignia 75-inch QLED Fire TV.
