PPI vs Quality?

[patriotaki]

Hi,

 

so i am currently using a 65" 4k tv with 69ppi, i am looking to buy a 75inch 4k tv but im conncerned about the quality.

In the showroom there was a samsung crystal 4k tv 85inches and from a close distance you could see the blurr-iness cause of the lower ppi (52ppi)

 

A 4k 75" tv has 59ppi, will the blurriness be that visible as the 85inch tv?

If i get a better quality tv for example samsung qled 75" q80 model, will it "balance out" the difference in PPI compared to a normal crystal uhd samsung 75" tv, or it doesnt matter at all?

 

I just want to see if it's worth it paying for a higher end model like a q80 compared to a crystal uhd model.

more ppi means sitting closer for the same level of quality.

 

bigger screen means sitting further away to get the same 'fov'

 

if you're sitting close enough to see the pixels on a 75" , you're probably sitting too close for a 75".

I have a 77" LG Oled and i have to get like 1m closer to it, until I start seeing pixels.

 

And I have to agree, if you can see the pixels on a 4k TV, youre sitting too close.

the pixels were visible in the showroom i was not sitting like i would do on my living room.

I was standing in front of the tv.

 

Does it make sense purchasing a samsung q80 for double the price of a normal crystal uhd 4k tv? (both 75")

 

Also, is the 120hz noticeable on daily usage (normal tv channels and fhd/4k movies) ?

I use a 48inch OLED and it is fine at 32-35in.  IMO that is the limit of being fine at that distance.  When I had a 27in 1080p monitor it was very noticeable but I'm fine with 1080p on 24in or lower.
