Our favorite 24-inch iMac M1 external monitors

These were some of the best external monitors for the 24-inch iMac M1. If I had to pick one of them, I would likely go for the Dell U2723QE Monitor. Not only does it offer a stunning 4K resolution, but it also includes a USB-C hub and has a sleek design. Otherwise, the Studio Display is another valid option, especially if you're a fan of Apple products and want a built-in webcam. If you're a gamer, then the OLED pick from Alienware is hands down the best out there. Of course, there's also the budget-friendly pick from HP if you're not looking to overspend on a monitor.

Ultimately, all of these externals monitors should work excellently with your 24-inch iMac. Though, keep in mind that this computer only supports one external display with up to 6K resolution. So your setup will be limited to two screens in total — the built-in display of the iMac, in addition to the external monitor you're getting.
