Amount of RAM necessary for 4K output to TV

[Thomas Hemming]

Hello,

I happened to read somewhere (which I obviously can't find now) that the amount of RAM could be a limiting factor for the output to a 4K tv. The idea is to buy a 43" LG tv to use as combined monitor and tv. Do I need to think of RAM when doing that? I'm getting a GTX1070 where I'll be using the HDMI port.

All input is appreciated!

How much memory will the GTX 1070 have? At least 4 GB?

Yes, it will have 8GB:

My question arose because I'm not sure I fully understand the link between RAM in the computer and the output to a screen.

I presume that you will install at least 8 GB of RAM in the computer, but 4K requires no additional memory when you use a discrete GPU. It does only when using processor graphics and it usually can't use more than 1 GB.

Thx. Yes, I was wondering if I should go 32GB instead of 16GB RAM.

It depends on the applications that you'll use.

I'll mainly use it to watch streaming services and some gaming. If that's what you're thinking.

Then 16 GB is enough. Ii would be different if you were editing 4K videos.

Thx. I can understand that video editing could require the extra RAM. Not for outputting 4K.
