TCL QM7K for PS5: Great Features, One Real Caveat

The TCL QM7K is a good match for PS5: it supports 4K at 120Hz, HDR, variable refresh rate (VRR), and automatic low-latency mode. Its main caveat is motion clarity: RTINGS found visible blur, especially at lower refresh rates, despite low input lag. RTINGS’ QM7K testing

Buy it if you want a Mini LED television that supports the console’s key gaming features. There is no compatibility-based reason to skip the QM7K for PS5; the decision turns on whether its motion handling meets your expectations.

Is the QM7K a good PS5 purchase?

The recommendation here centers on the US TCL 65QM7K, the size independently tested by RTINGS. Check the complete model number when shopping: this article concerns the QM7K, not the older QM7/QM751G or another similarly named TCL television.

TCL specifies a 3840 × 2160 panel with a native 144Hz refresh rate, plus automatic game mode. That exceeds the refresh rate needed for PS5’s 120Hz output. The extra headroom does not make a PS5 game run at 144 frames per second. TCL’s QM7K specification sheet

Do not base the purchase on Game Accelerator’s advertised 288Hz capability. That mode operates at 1080p, according to Tom’s Guide, and provides no additional refresh-rate benefit for PS5. More relevant is the publication’s 13.1ms input-lag measurement, taken with a Leo Bodnar 4K Input Lag Tester. That is a measured result, not a claim of instantaneous response, and should not be relabeled as a 120Hz measurement. Tom’s Guide’s QM7K review

Low input lag and clear motion describe different things. Input lag concerns how quickly the display responds; motion blur concerns how moving edges look. RTINGS specifically cautions that players accustomed to OLED will notice blur on the QM7K, particularly at lower refresh rates. If that describes you, explore the display-type tradeoffs in Mini LED vs OLED for PS5 Pro before choosing.

For HDR, Tom’s Guide measured 1,734 nits on a 10% window in Filmmaker Mode. That supports the television’s ability to produce bright highlights, but it is not a Game Master measurement or a brightness level every scene will reach. Avoid using that figure as a universal PS5 calibration target.

Connect PS5 without losing 4K/120Hz

Use HDMI 1 or HDMI 2 for the console. RTINGS confirms both accept up to 4K/144Hz. HDMI 4 carries eARC but has lower HDMI bandwidth, so connecting a soundbar there leaves both fast inputs available. A PS5, another high-refresh gaming device, and an eARC soundbar can therefore coexist without competing for the same two sockets. RTINGS’ input specifications

Start with the HDMI cable supplied with your PS5. Sony recommends it, or an Ultra High Speed HDMI cable rated for 4K/120Hz. An additional cable is unnecessary when the supplied one works and reaches the television.

Set up the connection in this order:

1. Connect PS5 directly to HDMI 1 or 2. Establish that connection before adding a receiver or HDMI switch.
2. Enable Game Master on the TV. TCL documents it under All settings > System > Game Master and identifies it as the control that enables VRR. TCL’s QM7K user manual
3. Set the input’s HDMI Mode to HDMI 2.1. RTINGS specifically recommends this for HDR gaming on the QM7K. Menu placement can change with software, so use the setting name rather than instructions for an unrelated TCL model. RTINGS’ QM7K gaming settings
4. On PS5, open Settings > Screen and Video > Video Output. Set Resolution to Automatic or 2160p; use Automatic for 120 Hz Output, VRR, and ALLM. Leave Video Transfer Rate on Automatic.
5. Set HDR to On When Supported, then run Adjust HDR. This preserves SDR output for games that do not support HDR. Sony’s video-output guide

For a useful HDR starting point, RTINGS uses Local Contrast: High, Dynamic Tone Mapping: Off, and Dynamic Contrast: Off, with Game Master enabled for gaming. Complete the console’s HDR adjustment after choosing the TV settings you intend to keep. Do not copy another panel’s white-balance calibration: RTINGS explicitly warns that those values differ between individual units.

You can also select Settings > Saved Data and Game/App Settings > Game Presets > Performance Mode or Resolution Mode > Performance Mode. Sony says this preference applies only to games that support the relevant presets. Check each game’s own graphics menu too; a performance preset is not a guarantee of 120fps. Sony’s game-preset instructions

When 120Hz is missing, or the picture looks wrong

If only one game stays at 60Hz, check that title’s supported modes first. A 120Hz-capable connection does not require every game to use 120Hz. Compare the same game mode when checking settings; otherwise, a change in the game itself can look like a television problem.

If 4K/120Hz is unavailable across supported games, revisit the port, HDMI Mode, and direct connection. Check for current TV and console software. The PS5’s Information for the Connected HDMI Device screen shows detected capabilities; distinguish those from the current output signal.

If the picture flickers, Sony suggests trying Video Transfer Rate: -1 or -2, but its documentation also lists 4K/120Hz among the outputs those settings limit. Treat them as diagnostic compromises, not settings that preserve every gaming feature. Restore Automatic when checking full capability. Sony’s output limitations and troubleshooting

Change one item at a time and record the result. For example, if a direct connection works but routing through a receiver fails, that points toward the intervening connection or equipment. It does not establish that the television needs replacing.

If moving objects smear while the signal remains stable, distinguish that from an HDMI dropout. A cable replacement is not an evidence-backed cure for the panel’s documented motion blur. Compare the game’s available performance modes before deciding whether the display is acceptable for the games you play.

Persistent black screens, repeated disconnects, or missing capabilities after checking both fast inputs and a known-good cable need further diagnosis. Contact TCL with the exact model, installed software version, affected games, and connection details. The available evidence does not establish one firmware update that cures every QM7K/PS5 complaint; a fault that survives those checks may require service or an RMA.
