… to what’s available on Amazon in 4K or 5K screens with no computer (iPad or iMac) attached, I can mostly only buy the LGs for $1400 to $1700, and they don’t work with a stylus. The comp isn’t really a monitor anyway, it’s a Wacom Cintiq Pro.
Have you ever used an iPad Pro with Sidecar - ie, as an external moniyor? I have! You're going to be compromising heavily. Bye bye to 120hz, you're going to be struggling to hit 60hz sometimes. Hello to video compression, so all those pixels are going to be far from what they can actually do.
Any real external monitor is, I'm sorry to tell you, going to blow it out of the water in image quality, and it's not even close. Especially if there is any movement or if you're going to be pushing more frames. It's just the name of the game.
It's real competition isn't external displays, because it really can't compete there. It's laptops with pen support. And it can't compete against those either. Believe me, I tried to make it work, it just can't.
