Ville, Daniel,
I've just got another monitor and another DVI-HDMI cable, and here what I've got.
===Single Link DVI-D cable with 3 different monitors===
Computer DVI ——— DVI-D (Single Link)/HDMI cable ——— HDMI LG 23MP65HQ-P === not working Computer DVI ——— DVI-D (Single Link)/HDMI cable ——— HDMI LG 23MP67HQ-P === not working Computer DVI ——— DVI-D (Single Link)/HDMI cable ——— HDMI LG 23MP55HQ-P === works!
===Dual Link DVI-D cable with monitor that doesn't work with Single Link cable===
Computer DVI ——— DVI-D (Dual Link)/HDMI cable ——— HDMI LG 23MP65HQ-P === works!
===Laptop with HDMI output===
Laptop HDMI ——— HDMI/HDMI cable ——— HDMI LG 23MP65HQ-P === works!
I'd say that single link DVI cables are broken with new kernel, but one of monitors could work with such a cable. So I have no idea :(.
Regards, Oleksandr.
