Our take on the Samsung QN75LST7
The Samsung QN75LST7 is a 75-inch 4K LCD TV from Samsung's 2020 lineup, built around a flat panel with local dimming and HDR support. It runs Tizen with all the major streaming apps and works with Alexa, Google Assistant and Bixby, plus AirPlay 2 and Miracast for casting. Its stereo 20W speakers and Dolby Digital Plus processing are modest next to soundbars, and it lacks VRR and high frame rate support, so it is a general-purpose living-room set rather than a gaming display. Shoppers comparing it with Samsung's QLED models should note it gives up wide viewing angles and peak brightness, while its tuner set (DVB-C, S2, T2) and three HDMI ports cover typical setups.

What reviewers say
Owner feedback on this set centers on its large 4K picture and easy Tizen setup, with most complaints aimed at sound quality and gaming features. Reviewers treat it as a solid big-screen TV for streaming and broadcast rather than a gaming or home-theater centerpiece.
- Picture qualityPraisedOwners describe a bright, detailed 4K image that suits everyday streaming and broadcast.
- SoundCriticisedThe 20W stereo speakers are called thin, and many owners add a soundbar.
- Gaming featuresCriticisedThe lack of VRR and high frame rate support limits it for console gamers.
Questions and answers
- Is the Samsung QN75LST7 good for gaming?
- Only casually. It has no VRR and no high frame rate support, so fast console games will not look as smooth as on newer gaming TVs.
- Does it need a soundbar?
- Most owners think so. The built-in 20W stereo speakers are serviceable for news but thin for movies, and Dolby Digital Plus processing does not add much bass.
- Can I wall-mount it?
- Yes. It is VESA mount compatible, and at about 111 lb without legs it needs a mount rated for a large TV and a stud-finder installation.
- What streaming and casting does it support?
- It runs Tizen with the major streaming apps and supports AirPlay 2, Miracast and DLNA, so you can cast from Apple and Android devices.
- Does it have a built-in TV tuner?
- Yes. It includes DVB-C, DVB-S2 and DVB-T2 tuners, so it can receive cable, satellite and terrestrial broadcasts without a separate box.
- How many HDMI ports does it have?
- Three HDMI inputs, plus optical S/PDIF, USB-A and Ethernet. That is enough for a console, a streaming stick and a soundbar, but not much more.
