I wanted to add a 2nd VGA display to my laptop.
Laptop (HP Pavilion 15) has a single USB-C port.
Value Line device is described as providing a VGA port; powered and signalled via the host's USB-C port.
Laptop is Windows 10 (version 1709) that supports the Alt Display via a USB-C port.
Whilst the USB-A port works fine, supporting my wireless mouse, the VGA port has NEVER worked. I don't have a native USB-C external device to test the third USB-C port on this multiple port device.
Searching has yet to identify an up-to-date software driver for this device. Current software driver is dated 2006.
There is no information whether there is a Windows 10 registry setting inhibiting correct operation.
Awaiting delivery of HP's own USB-C to VGA connector purchased from the HP Store. This indicates that HP expects their laptop to support a 2nd display via this route.
On balance, I WOULD NOT RECOMMEND this device due to the apparent lack of detailed technical support.
Disadvantages and advantages
- VGA port has never worked.
- Cannot find up-to-date device specific software driver.
- Current software driver dated 2006.
- USB-A port works fine.
