Questions about Dell P2425HE

To create a daisy chain with the Dell P2425HE and another monitor such as the P2425H, you need a connection via DisplayPort, as HDMI is not suitable for daisy chaining. The P2425HE has two DisplayPort connections, which theoretically enables daisy chaining. However, it is important that the monitors support DisplayPort 1.2 with Multi-Stream Transport (MST) in order to operate multiple monitors in a chain. Connection via USB-C is possible if this connection supports DisplayPort Alternate Mode, which is the case with this model. To answer your specific question, you can connect the P2419H to the P2425HE via DisplayPort and then connect it to the laptop via USB-C, provided that the USB-C interface supports DisplayPort Alternate Mode. However, it is important that all devices involved fulfil the necessary requirements for daisy chaining.

To create a daisy chain with the Dell P2419H downstream, you need a monitor model that has a DisplayPort output. The P2419H does not have a DisplayPort output, which makes a daisy chain impossible. The P2425HE has DisplayPort inputs, but no information about a DisplayPort output is available. Therefore, it is unlikely that you will be able to use the P2425HE as an intermediate stage in a daisy chain if it does not have a DisplayPort output. However, you can connect the P2425HE directly to the laptop via USB-C if the laptop supports USB-C with DisplayPort alternate mode.

It is not possible to create a daisy chain with the Dell P2419H downstream by connecting the P2419H to the P2425HE via HDMI and the P2425HE to the laptop via USB-C. Daisy chaining is not supported via HDMI. Instead, you need DisplayPort, USB-C with DisplayPort Alternate Mode or Thunderbolt to create a daisy chain. To realise a daisy chain, the P2419H would have to be connected via DisplayPort, which is not possible with this model as it does not have a DisplayPort connection. Alternatively, you could connect the P2425HE directly to the laptop via USB-C and then include another monitor that supports DisplayPort in the daisy chain.

The Dell P2425HE monitor has the following connections: - Video ports: 1x HDMI 1.4, 2x DisplayPort 1.4 (1x input, 1x output). - USB ports: 1x USB-C 3.2 Gen 1 (upstream with up to 90 W Power Delivery), 1x USB-C 3.2 Gen 1 (downstream with up to 15 W, data only), 3x USB-A 3.2 Gen 1 (downstream). - Network: 1x Ethernet RJ45. - Audio: 1x 3.5mm audio output.

The aspect ratio of the Dell P2425HE monitor is 16:9.
