Why is the input latency so bad on the display? The touch/draw visibly lags behind by 500ms or more, is that an issue with the software or with the hardware? Also seems to be an issue with registering touches, as Kornacki often has to press two or more times when toggling between screens.

IMO we should have the technology to make the input lag an order of magnitude smaller, right? I didn’t see any mention of latency on the blog post so I’m wondering if the author doesn’t see it as a problem.

not sure how it is now, but last time I looked into this it's because the board feed is run back through a control room for color correction, and then back into the display - if you run it directly on the display without color correction it's much better, this is one of the things that annoyed me the most but beyond my scope

This. I can't watch people like Harry Ente, not least because of the pain in watching the delay when they draw or click on something.

One likely factor: the video we're watching is from 2016. I think input latency has gotten more attention (optimization effort) since then.

A lot of the time this cycle, Kornacki would tap the "Draw/Pen Mode" icon, accidentally write on the screen when he meant to tap a button, tap the same icon to exit draw mode, then actually touch the button he wanted. He did that _so many times_ on stream it was crazy. Wonder if they can wire in a "pen" to get rid of that UX nightmare for him.

I came into the comments to say exactly this! The latency was soooo bad during the recent election coverage.

I bet NBC hasn't touched the code nor the hardware it runs on since it was developed 8 years ago.
