can i daisy chain another monitor from my dell u2722de? how does the dp out port work?

Yes, you can, using the DisplayPort Out (DP out) port. This enables Multi-Stream Transport (MST) for daisy-chaining.

1. First, ensure your computer's graphics card supports DisplayPort 1.2 MST or later.
2. Connect your computer to the primary monitor's DisplayPort In port.
3. Connect a standard DisplayPort cable from the primary monitor's DisplayPort Out port to the DisplayPort In port on the second monitor.
4. On the primary monitor (U2722DE), you need to enable MST. Navigate the OSD menu to Menu > Display Settings > Multi-Stream Transport and set it to On.
5. You may need to configure extended display settings in your computer's operating system (like Windows Display Settings).

IF THAT DIDN'T WORK: The second monitor must also support DisplayPort MST daisy-chaining. Not all monitors do. Also, remember to remove the small rubber plug from the DP Out port on the primary monitor before connecting the cable.

HEADS UP: When using MST, the total bandwidth is shared across the chain. For high resolutions like 2560 x 1440 on multiple monitors, ensure your source computer has a capable graphics card. The maximum resolution for the USB-C input on the U2722DE is 2560 x 1440 at 60Hz.
