Help me choose the right size for my HDTV

[knowledge2121]

I want to upgrade to a 4K TV for PC/Console gaming purposes I am wondering which TV size is right for me...

I play with a Keyboard/Mouse and sometimes a controller..When I play with the KB/M my distance from the TV is about 34-55 centimeters...When I play with the controller the distance is more .. it is around 70-80 centimeters...What screen size should I get ?

more questions:

Can you recommend a 4K TV under 700 CDN with the right size, low response time and good picture ?

is it correct that all 4K TV's support up to 60 fps' ? since All of the current ones use HDMI 2.0 ?

Are there TV's with HDMI 2.1 or DisplayPort inputs ?

'' is it correct that all 4K TV's support up to 60 fps' '' . no, download and read the manuals for any tv your interested in and review all the PC use specs and requirements [before you buy it ]

like this one [specifications ]

Response Time 6.5 ms (gray to gray)

PC timing
3840x2160 Up to 60 Hz (HDMI1, 2, 3 only), Up to 30Hz (HDMI4 only)
1920 x 1080
1360 x 768 1280 x 1024 1024 x 768 800 x 600

then like this one of theres don't have any of the specs listed ??

would not trust that one to do 4k@ 60 under pc use or any pc use at all just cause there not stating that or showing any specs .

anyway the more you see PC use covered the better chance you will have of satisfaction . I like to see a bit more on it then just how to plug it in .

''or DisplayPort inputs '' no, I dont get why they don't seems needed bad or would be a good feature to have today
