Connecting 2 x Dell U2723QE to a Macbook Pro M2 Max

specs for MacBook Pro with M2 Max processor say it supports up to four external displays.

It is not clear whether the 14-in model (if that is what you have -- you did not specify) has more than two Thunderbolt ports.

¿do you have the 16-in model?

Hello longcha14,

This article provides information on connecting your display to your Mac: Connect a display to your Mac - Apple Support

1. Use your display's power cable to connect the display to power.

2. Use your display's video cable to connect the display to your Mac, such as to a Thunderbolt  or HDMI port. Different ports might look similar, so it's important to identify the port correctly.

3. If the video cable requires a port that your Mac doesn't have, you might be able to use an adapter with the video cable. Or replace the video cable with one that doesn't require an adapter.

4. When your display has power and is connected properly, your Mac detects the display automatically. You should then see your Mac desktop on the display, and you can configure display settings.

Thanks for using the Apple Support Communities, and have a great day!

Hi, longcha14-nice monitors, btw ! These support usb-c, DisplayPort and hdmi… i think your m2max mac book pro supports DisplayPort ( Alt mode) plus Thunderbolt 3 so no worries there… however it only has 2 ports which is sorta a drag… so use a powered Thunderbolt 3 dock, which should have loads more ports… I wouldn’t be inclined to change ‘em out for 2 monitors that support Thunderbolt 3 ( unless you want to spend the money, that is)
