I have a problem with my windows 10 pc. It has 2 monitors : the first one (Samsung S22B350) that is plugged by DVI into the GPU (NVidia 730) with a DVI to HDMI cable, the second monitor(Samsung S27E591C) is plugged into the GPU with a HDMI to HDMI cable. This used to work perfectly fine but since last week whenever I start/restart the PC after the Bios screen it turns black (there's no image on any monitor). For it to work I have to unplug the second monitor and replug it when the pc is on. The desktop then extends to the second monitor but not in its native resolution, which I have to force through the NVidia control panel. The pc also doesn't really detect the second monitor correctly (it doesn't show its serial number anywhere and detects it as a generic monitor with an incorrect max resolution).

Welcome to Bleeping Computer.


Have you tried updating the nVidia drivers?

When video cards fail in a two  display array, the adapter, DVI to HDMI could be the fault and not being recognized, defaulting to onboard native resolution.  Not a fan of adapters, another piece to fail and not always the perfect modification.  HDNI likes to handshake with displays and TVs but may not recognize or be recognized during boot up.
