It has 4 HDMI inputs and a USB-C with display port. It even has a remote.
It's an IPS panel though. From what I hear not everyone loves those.
Amazon has it in France for around €600.

My receiver is older and doesn’t have HDMI in, but this solution works well with the TV I have. When a device is turned on, the TV wakes up and switches to that input. If the PS4 is on and I turn on the Apple TV, it will auto-switch. I never need to touch the TV remote at all since the devices go to sleep automatically, which is nice. Apple TV remote handles the receiver volume, and the audio input never changes on the receiver, so I don’t need the TV or receiver remotes at all.
I'm wary of using HDMI AVRs today because they add input lag.
For my computer, I use a 32" LG 4K monitor, and it's great. No 'smart' features found there.
But I can't find a 4K monitor in the 42-50" range that has multiple HDMI inputs that is not incredibly pricey (e.g. broadcast/commercial realm) I could use in my living room.
