Enable 4k resolution on digital signage
I would like digital sign feeds to be able to be 4k resolution. Right now they are capped at 1080p. Content made in photoshop at 4k resolution gets down scaled to 1080p, then it gets displayed on a 4k TV and text and images become soft.

If you want the highest quality of picture and sound, you're going to want HDMI cables. For your Ultra HD Blu-ray player or 4K streaming device, make sure to get a 4K-supported cable, like this 6-foot high-speed 2.0 HDMI cable for $12. Then check your TV manual to see which ports on your TV you should be using for UHD.

I need this too! We are streaming 5 NDI cameras @ 2160p24 through Livestream Studio. The Proclaim NDI feed is coming in @ 1080p29.97, which Livestream has to convert and it gets really wonky. If I could set it to match my camera feed, then everything would be great! Thanks!
