My path.
Up to 2013, I used a 27" 1440 monitor from 0,6-0,8mt.
I cannot see clearly enough on short distances. It's now 50 years I've been wearing double and then multifocal
<I can still read a newspaper standing on it without spectacles>
I passed to a 32" Samsung Monitor/Tv from 1mt-80cm
Then I decided to save some money and got an old Samsung TV 44" FHD using it from 1,20-1,60mt,. That lasted 1 year or a little less
In 2018 I invested some money in a cheap Samsung TV 55" and started to use it a 1,60-1,80mt . The Same distance that I still use now.
At that time I thought it was not bad at all, but that 55" got too many issues and after 18 months I ended up relegating it to the kitchen.
Bought a Samsung TV 65" 4k normal LED.
Things had a small improvement but brightness was an issue, I cannot have a Day/Sun/Night separated setting easy to use.
This year I changed it to an LG Qled 4K 65" - WOW -
With this kind of LED, there is a huge change in crispness and definition.
And more .. the software is simpler and gives you great customization opportunities, and you can save everything in 7 different "modes"
really better than any of the previous ones I had used!!
For photos, I use the 300% 😔
What I've found is that all the LEDs are not the same.
Better technology, better seeing experience.
The jump in the last 4 years makes it worth changing anything older than 5 years and doing it now.
Mostly stuck in bed, I'm in front of my screen and my PC runs 12 to 20 hours per day
( In the last 10 years that's an average of 10 hours each day)
