UP" Mini Laser Scanning Camping Projector for iPhone 15,16/Android , Focus-free, 720p, 100" Projection Size, 34 ANSI, 4K Compatible, Auto Keystone, Low Power Consumption, USB-C DisplayPort

AnyBeam Up this will get you a 720p image the size of a computer monitor. The only reason to get this over a higher resolution monitor is that it is smaller, lighter, and uses less power. Also, it doesn't have any sound capability (audio should play through the phone speaker) and your device needs to support USB-C video (hdmi adapters are available separately). It's $350. If you want a bigger and/or higher resolution image the price only goes up.
