Questions about Rollei Viltrox DC-X2

As we do not have effective user experience with the product, we have forwarded your question to the Community so that it may be answered by another customer.

The firmware for the Rollei Viltrox DC-X2 monitor is not directly linked or described in the available sources. Official firmware updates can usually be found on the Rollei or Viltrox manufacturer's website. Since you have already searched the internet, I recommend searching directly on the official Rollei website or the Viltrox website for a support or download area for firmware updates. Alternatively, you can contact Rollei customer service to get the latest firmware and update instructions. For the "No Signal" problem with the Nikon camera, you should make sure that the HDMI output of the camera is set to a compatible format and that the HDMI cable and the connections on the monitor and camera are working properly. Sometimes it also helps to restart the monitor or check the HDMI settings on the camera. A direct firmware download source or update instructions for the DC-X2 monitor are not included in the information provided.

The problem with the monitor not displaying an image at 120fps on the Nikon Z7II is probably not due to the monitor itself. The Viltrox DC-X2 supports HDMI inputs up to 4K at 30Hz, which means that at higher frame rates such as 120fps in Full HD, the camera may be outputting a signal that the monitor cannot process. The monitor has a refresh rate of 60Hz, which is not sufficient for 120fps. It is therefore very likely that the Nikon Z7II is sending a signal at 120fps that the monitor does not support, which explains the missing image. A monitor with a higher refresh rate or special support for 120fps would be required for this application.
