VRAM help!

[hazza_ob]

When creating a triple monitor setup i've heard people say that you'll need more VRAM in your GPUs. Is this true and if so why? Also how much of it would you suggest using when looking at 1440p gaming across three monitors? 

Thanks - Harry

4-6GB of VRAM.

You'll need more VRAM, because the GPU has got to put out a much bigger resolution... thats why 4K takes up a butt tonne of VRAM whereas 1080p is alot less

but why is more needed for more monitors?

if you plan to game over thoose monitors then its x3 the resolution of 1440p. If you dont plan to game across all 3 then you dont need to worry about extra VRAM.

Because you have more horizontal resolution.

 

You'd typically have 1920x1080 for a single monitor.

And then you add another monitor. You still have the same vertical resolution but twice the horizontal.

4gb will be enough for now unless the game you play has terrible optimization aka ubisoft games.

More monitors = more pixels 

Higher resolution = more pixels

More pixels = more VRAM needed

 

 

Can't really put it any other way.

well if you've got 3 monitors at 1440p, that means that you have got 3 lots of 2560x1440 pixels, which adds up to 7680x4320. The more pixels needed, puts stress on the VRAM, and would require more than just a simple 1920x1080 monitor
