I have 2 LG HDMI monitors connected in separate ports. Windows 10 will only detect 1. The other says no signal. Tried Rigorous Detection in NVIDIA control panel and that also failed. Please help!
Thanks for the reply. A friend looked at it. Apparently when the graphics card was upgraded after manufacture, it doesn't support the other two HDMI ports on the tower. Have just gone and bought a DVI cable for second monitor and that should sort it out.
