Review: Fantastic quality, little money - This was going to be a rant about the delivery which was supposed to be on Thursday ( to which I organised someone to be in) but on Wednesday afternoon was moved to Sunday ( Mothers day, so had to wait in, not visit mum). Not delivery firms fault, but seller. However, this tv has taken my breath away. It's replacing a 2 year old LG ( gone to mum to replace an old non smart tv) which I have been disappointed with. Pound for pound this is hugely superior, I've always had LG but not any more. Colour fade out started at about 5 degrees on LG and at 15 degrees was unwatchable, this Samsung has minimal fade out at 30 degrees and even at 70 degrees is still agreeable. Picture quality is superb with very little tweaking, sound is brilliant, hardly use sound bar now, and most everything is easy to find. The remote got mixed reviews but up against the LG one, this is a doddle and nice to use. Set up and connectivity so simple the tv virtually did it for me. This is without a doubt the best tv I've bought, fabulous value for money and if it lasts as long as my Samsung phones it'll probably be the last tv I buy. ( if not, it'll be another Samsung). If you're looking for a top tv for budget money you can't go wrong with the QE F1 Samsung, brilliant.
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!

Picture quality is superb with very little tweaking, sound is brilliant, hardly use sound bar now, and most everything is easy to find. The remote got mixed reviews but up against the LG one, this is a doddle and nice to use. Set up and connectivity so simple the tv virtually did it for me. This is without a doubt the best tv I've bought, fabulous value for money and if it lasts as long as my Samsung phones it'll probably be the last tv I buy. ( if not, it'll be another Samsung). If you're looking for a top tv for budget money you can't go wrong with the QE F1 Samsung, brilliant.

### ⭐⭐⭐⭐⭐ Cracking TV for the money
*by T***O on 2 January 2026*

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!

### ⭐⭐⭐⭐ 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🙂
