Been using Noir Pro: USB Camera HDMI Link for a couple months now. It’s basically an app that lets you use your phone as a portable display for HDMI devices like gaming consoles or cameras. Pretty solid app if you’re into that kind of thing.
Here’s what you do: you can connect your phone to an HDMI source using a USB-C capture card, and then use Noir Pro to view and record the feed. There’s also a bunch of pro features like 3D LUTs, waveform monitor, and edge detection – took me a while to figure those out but they’re useful. And the app-specific volume control is a nice touch.
Look, if you’re into video production or just want to use your phone as a portable monitor, you’ll probably like this. It’s not perfect – the ads can get annoying if you don’t pay – but overall it does the job. Worth checking out.
