4k tv's and rendering size

[J. Brown]

So we got this new fancy 4k 60" tv in our office to show presentations on. What size do i need to start rendering out to take advantage of the screen quality?5600x3600 is a big image that takes a lot of time! Any suggestions?

I would try 2800 x 1800-- either upsample in PhotoShop or just let your display software zoom it.  It won't take full advantage of the display but should be pretty nice.

I have a few at 3000x2000. They take forever! Still get pixilated. Might be a video driver thing i am starting to think... might not be strong enough to handle that much resolution. I don't know enough about 4k to truly know the fix but wanted to start with rendering so it isn't my fault.

These are 6 megapixel images-- they will take a long time.

Try displaying some hi-res images from your phone or camera to see if it's a video driver problem.

Could be many other things.  Can't tell without seeing examples.
