Hi,
I bought a AndyCine A6II HDMI camera monitor. But the display can't be connected to my X-T3. I had the same problem with an earlier bought Viltrox DC-550 pro camera monitor. If I put my camera to a HDMI port of my computer monitor it shows the picture from the camera. This monitor is able to display a 4K 25frames, and below, videosignal. I had a Viltrox lens attached to my camera, later I switched it for a Fujifilm 18-55mm. Any idea what could be wrong?
