There are many aspects to take into account in addition to the size of the screen, we recommend you to read our TV shopping guide.
55 inches FullHD cheaper
- LG LH604V: £599 Good Smart and viewing angle
- Samsung K5500: £520 Good for watching movies in the dark, good Smart
- Panasonic DS500B: £420
55 inches 4K cheaper
- Sony XD7005: £730 Best for viewing in lighted, lower Smart
- Samsung KU6000: £600 Better to see from the front, good for gamers
If your budget is about 600 € is a bit low for a 55-inch TV, unless you find a good deal. If you also want a TV to play with the PS4 better a Samsung TV.
The K5500 is the equivalent of the one you have, but with better Smart and this year. The KU6000 / KU6400 is the equivalent to which the Jaume was bought at the time.
