Oled , Brilliant oley oley
I can’t talk technically (it’s all modern stuff now !) I moved house and promised myself a better TV system and so I toddled of to the local tv dealer in our town to view and talk about tvs , I felt it may be important to inform him I have been a staunch Samsung believer and have been for many years ! I had a quick demo ( that’s all that was needed really) of a couple of TVs of varying types normal HD but the newer types and the OLED ones ! Being an old fan of HD TVs when you view that type it’s as if someone was a dirty piece of plastic in front of the screen compared to the Bravia OLED 55” , that was crystal clear and bright ! Just a quick view was all that was really needed and once I’d seen the Sony Bravia models , the clarity , colours and sharpness of them I knew that was the type I was going to buy , had to buy to be more precise , there was just no real comparison, yes they were more expensive but what the heck , the old house would pay for that and with a 5 year guarantee, what’s not to like ? By by Samsung ! The TV Engineers came on Wednesday to help set it up and they were very polite and efficient and did so and took away any unnecessary ‘bits and pieces! ‘ So now it was left to me to figure out all these apps and free to view programmes, well that in itself is another full booklet to describe and I thought I would be quite good at this , however it was dragging on but not affecting the football but I made my mind up that I would still purchase a second tv for my bedroom and the England matches were getting tighter as the games went on and the kick off times were not doing my sleep any good at all and especially at my age ! So back to the retailers and without any hesitation (I knew which type I wanted) I did the deal on a Sony Bravia 48” this time , I was so impressed with the TV and picture quality etc it was not a hard choice at all ! I’m still finding my way around the new set ups, how to find this programme or switch back to normal tv , is there such a thing as normal these days ? I doubt it !

Absolutely Outstanding – The Best TV I've Ever Own
The Sony K-55XR8A has completely exceeded my expectations. From the moment I switched it on, I was blown away by the incredible picture quality. Colours are rich, vibrant, and lifelike, while blacks are deep and detailed, creating a truly cinematic experience in my living room. What really sets this TV apart is the stunning clarity and processing. Whether I'm watching films, live sport, or streaming high-definition content, everything looks exceptionally sharp and smooth. Fast-moving scenes are handled effortlessly, and the level of detail is remarkable. The sound quality is equally impressive. Unlike many modern TVs that require an immediate soundbar upgrade, the K-55XR8A delivers clear dialogue, excellent balance, and a surprisingly immersive audio experience on its own. The smart TV interface is fast, intuitive, and packed with features. Apps load quickly, navigation is seamless, and the overall user experience feels premium and refined. Sony has clearly paid attention to every detail. Build quality is another highlight. The television looks elegant and sophisticated, with a sleek design that enhances any room. It feels like a genuinely high-end product. Overall, the Sony K-55XR8A is a fantastic investment and an absolute pleasure to use every day. If you're looking for superb picture quality, excellent sound, premium design, and a smooth smart-TV experience, this television delivers on every front. Highly recommended!

Just great 👍
We've had this tv for a few weeks now and are extremely pleased with it the picture compared to our old LG 8k is absolutely brilliant and even without a sound bar is terrific. With so many choices it can be confusing as to which one to buy, but if you choose this one I'm feel sure you won't be disappointed.

No dout SONY
I bought this TV three weeks ago to replace a Samsung 8K that died on me. This Sony feels even better, even the remote when it's glow in the dark. The only problem I have right now is that it's a bit dark during the day sometimes, but I knew that before I bought it since it's an OLED and not a mini-LED. I hope we get the option to enjoy Sony Core. We don't have it in Israel, unfortunately.
