M5 MacBook Pro with 2 Dell P2720DC monitors not daisy chaining

Hello,

I just received my new M5 MacBook Pro. This is my first MacBook after a long time and the first I want to connect to my current set-up. My old laptop was a Dell XPS.

My current set up are two P2720DC monitors from Dell. They are configured to daisy chain via DP out - DP in (Described on page 28 https://dl.dell.com/manuals/all-products/esuprt_electronics_accessories/esuprt_electronics_accessories_monitor/esuprt_monitor_p_series/dell-p2720dc-monitor_user's-guide_en-us.pdf). But I don't get daisy chaining working.

Macs do not support DisplayPort MST daisy-chaining – so you cannot use that monitor feature.

Macs that can drive multiple external monitors can generally drive

• One monitor using a plain USB-C connection, adapter, or hub/dock
• Up to two monitors if the device connected directly to the Mac is a Thunderbolt one, such as a Thunderbolt hub, dock, or dual-display adapter.

Problem begins with the second monitor. It is just showing the same output as the first monitor, no new monitor. Also just one external monitor is visible in the MacBook settings.

Typical symptom of trying to use MST. Both monitors get driven off a single hardware video output (so they seem to be mirroring), and the Mac only sees one of them.

Can I get this set-up to work? If so, does anyone know how to configure this? I don't want to use two USB-C cables.

Then you'll need a Thunderbolt hub, dock, or dual-display adapter.

think you may have to use 2 thunderbolt ports
