I was in a similar position a year or so ago, needing to replace a very old set but mystified by the choice of Smart TVs and wary of making an expensive mistake.
I decided to buy a Samsung 32" Smart HDTV set costing around £250 just to see how I got on with the new tech. It’s fine apart from daytime viewing where very dark scenes can be obscured by reflection of my cream-coloured sofa. You may need to consider the more expensive OLED or QLED sets to avoid that. I just chuck a dark throw over the sofa!
I receive the free-to-air digital terrestial channels (DTV) (including Sky Arts) though the existing aerial and subscribe to the popular no-contract digital apps: Netflix, Amazon Prime, Now, Britbox and one or two more niche apps. These are delivered via your broadband router as are BBC iPlayer, ITVHub, All4, My5 and UKTVPlay (Dave, Yesterday and Drama) which are free.
The TV was easy to set up. Have your laptop, tablet or phone nearby as you need to register the TV and set up accounts for any apps you decide to subscribe to. It's easier to do it that way rather than with the on TV screen keyboard.
I had been a Sky subscriber for many years. With the Sky box gone, I thought I’d need a separate recording device so bought a Humax. This is also fine, although with so much digital content available on demand, I hardly use it. Apart from news, I rarely watch live DTV.
After a few weeks of using the new set, I added a basic Samsung soundbar to boost the sound quality. I don’t have a separate music system so listen to music on Amazon or Spotify through the TV and like the enhanced sound quality that a soundbar gives.
Check to make sure that the TV set you are considering has enough USB and HDMI ports for the number of external devices you need to connect.
A year on, I’m very happy with the set up. The recorder and soundbar were optional, of course. The £250 for the TV was money well spent. My last set was twenty years old, state of the art at the time and cost £1200! Nowadays, with TV technology advancing so quickly, I’d be reluctant to pay even half that for a new set.
When I look at the reviews for the Samsung, I see a lot of people have bought it as a second or third TV for their bedrooms or children’s rooms so if you opted for that, or similar, and discover it doesn’t suit, I reckon you’d be able to sell it on quite easily without too much of a loss.
I've probably gone into too much detail but by the same token know that a lot of people are as mystified as I was by newer TVs and feel a bit stressed over it all. I think even the term "smart TV" is confusing. My old set had a "smart" setting but that only meant that it could detect the optimal picture size for a particular program.
I hope you find something to suit you winterwhite.
