I bought this monitor https://www.laptopsdirect.co.uk/electriq-32-4k-freesync-monitor-eiq-324kmalu/version.asp about 6 weeks ago and it's run fine. Suddenly my monitor has randomly developed a weird issue. It has stopped displaying when plugged into any Nvidia graphics card via HDMI. It just stopped as I was using it. I've tried multiple HDMI cables, I've tried reinstalling windows onto the PC, I've updated the PC BIOS. I've switched the graphics card from a GT 1030 to an RTX 2060. Still nothing. Weirdly, it works with Intel & AMD graphics via HDMI, and with Nvidia via Display-Port. Just not Nvidia through HDMI, which is a problem as I use the monitor with a GT 1030 with no Display Port out. Any advice? I don't want to have to return it.
