Hi NewAuthor, Welcome to Microsoft Community. Thank you for posting your inquiry regarding your multi-monitor configuration issue.
Setting up dual monitors on your HP15 Pavilion laptop 15-CS2064 involves several considerations, including hardware limitations, signal processing, bandwidth, and device characteristics.
Firstly, the HDMI splitter. While an HDMI splitter can duplicate the display signal to multiple monitors, it does not extend the display. This means both monitors will show the same content, which might not be what you're aiming for. HDMI splitters are generally used for mirroring displays rather than creating an extended desktop environment. If your goal is to have two separate displays, an HDMI splitter might not be the best solution.
Next, let's consider the USB-C dongle. The HP15 Pavilion 15-CS2064 has a USB-C port, but it's essential to check if it supports video output. Not all USB-C ports have this capability, as some are limited to data transfer only. If your USB-C port supports DisplayPort Alt Mode, you can use a USB-C dongle with HDMI or DisplayPort outputs to connect an additional monitor. However, if the port does not support video output, this option won't work. You can verify this by checking the laptop's specifications or consulting the user manual.
On some devices, ports may have special logos to indicate whether they support certain protocol-related features.
In addition, your device appears to indicate that the port only supports data transfer, which means you may need to consider the voltage/power requirements of the adapter itself.

Regarding the USB-C dongle with an HDMI interface, this option may be feasible if your USB-C port supports video output. A USB-C dongle with multiple HDMI ports can allow you to connect two monitors, provided the dongle supports dual display output. It's crucial to ensure that the dongle has the necessary bandwidth to handle two high-resolution displays. Some dongles might only support one external monitor or have limitations on the resolution and refresh rate for dual monitors.
