Speaking of video, I’m on my second MacBook Air and have been very happy with them both except for one consistent concern, their unreliability with regard to external displays. It bothers me sufficiently for me to bring my Apple TV with me when delivering training, which is kinda ridiculous. I think my next one will be a Pro. That’s a pity really – I like the Air form factor and I don’t really need the extra power. I do think I need a real HDMI port though.
If you're dependent on the adapter, you need to use the Apple ones, or you need to have multiple. Sometimes HDMI works, sometimes it doesn't, changing the adapter usually fixes it.
Sure, but there are plenty of adapters that drive 4k@60Hz without an issue, such as the latest revision Apple's adapter (old revisions would only do 4k@30).
What do you use to connect the screen to your Air? I've got an M2 air, and recently purchased a 5120x1440 screen with HDMI and DisplayPort outputs. I first connected it through HDMI to one of the USB/HDMI/USB-C Apple adapters, and the result was terrible. But I ordered a DisplayPort->USB-C cable, and it worked perfectly.
