Review: Cracking TV for the money - Bought this TV to replace our 10 year old LG which was getting a bit slow. Mostly really easy to set up, but it took a bit of digging to work out how to scan for Freesat / Freeview channels. Once that was out of the way though, very happy with it. The picture is great, nice, bright and sharp and the 4k AI upscaling is very impressive - basically makes non-HD channels look like HD which is nice! Despite what some online reviews say, the sound is fine, good in fact. I've seen a few reviews that seem to compare this to a high-end TV, which seems a bit unfair as the Q7FA isn't that. I'm not a serious gamer, I'm not bothered about turning my living room into a bone fide cinema and I don't want to spend over a grand on a TV... If you want a truly high-end TV experience you'd better get your hand in your pocket, but if you want a perfectly nice telly for a very reasonable price, you won't go far wrong with this one. Exceptional value!
Review: Big upgrade, excellent picture, and finally no more HDMI headaches - We’ve stuck with Samsung TVs for years — mainly for the quality and reliability — and this 65” QLED has been a fantastic upgrade for our family. We were replacing a well-loved but aging TV (over a decade old), and the difference is night and day. Setup was a breeze — we’re running this with a Sonos Beam, Sub, and two Play:1s for surround sound, and everything just worked straight away. With our old TV we always had minor issues with audio syncing or switching sources, but this time the setup was smooth and stayed stable. The picture is excellent — rich colours, crisp detail, and much brighter than our previous TV. Even standard-definition programmes look better thanks to the built-in AI upscaling. 4K and HDR content really pops, and the larger screen size has made a real difference for movie nights. We also have a Fire TV Cube, but honestly, it feels a bit redundant now. The built-in Samsung interface is snappy and includes all the main streaming apps we use (Netflix, Disney+, Prime, etc). Unless you need something really specific, the native smart system does the job well. We use it for a bit of everything — films, kids’ shows, the odd game console — and it handles all of it with no fuss. Pros: •Fantastic picture, especially for 4K and HDR content •Easy integration with our Sonos system •Built-in apps and Samsung smart hub are fast and full-featured •Reliable brand we trust (and it shows) Minor cons: •Not quite the top-tier gaming specs (no 120Hz or full HDMI 2.1), but still fine for casual use. It’s not been an issue for us at all. Overall, this has been a great buy. If you’re ready for a proper upgrade and want something that just works, this is a solid choice. No regrets!

### ⭐⭐⭐⭐ A decent TV
*by R***R on 18 October 2025*

I’ve had the TV 5 days and so far it seems good. The picture is excellent and the found is good with the TV speakers. It has a lot of apps, which might be great for some people, but personally I find most quite pointless. I haven’t found ‘navigating’ the TV very easy; it’s not as straightforward as I would like. I play a lot of games on XBox & it links fine with the TV, which also has built in games you can play without a console. The main issue I found there is that you can’t use the same Xbox controller for the TV & XBox, you need a controller for each. The remote is not good as far as I’m concerned; it is too small (I know this might be a plus for some) & I find it difficult to handle. One thing I find really annoying is that when you mute sound the ‘mute’ icon comes on the screen & flashes & it stays on screen! I don’t know if this is a glitch or intentional but it’s not good. So I have to turn volume all the way down rather than just hit mute. Overall I love the picture & sound quality; the TV looks very nice & is quite light; it has many features but not sure I want or need most of them; the price was good too. I would recommend this TV & maybe after more time I’ll work out how to do everything🙂
