4k monitor or tv / pc monitor

Hello everyone

I want to get an 4K monitor or tv, for my PC

After i googled it a lot, i found this 40 inch monitor :

Philips BDM4065UC

Specs :

It seems to be a good choice, but i also consider an 4K tv as a pc monitor

What do you think about this one ?

Samsung UE48HU7500

inputlag - 41ms in [PC] mode

Is that very bad ?

The 48 inches 4K TV has the same ppi like the 32 inches 1440p

That means 91.79 ppi, which i think, it's okay

If the ppi is the same for both, 32 inch 1440p and 48 inch 4K, that means, the fonts, letters, GUI etc would be the same size ?!

Thank you
