I presume the above LG screen is what you've called previously "old monitor"?
Correct.
Computer DVI ——— DVI-D (Dual Link)/HDMI cable ——— HDMI LG 23MP65HQ-P
works!
Funky. Can you pls grab the debug logs (with the special patches from Ville) for this case? I wonder why suddenly different cable and it works.
OK, but will have to steal it again, as it is the only dual link cable I could find on another workplace.
Also: Is this one of these older-ish screens where you must have a dual-link cable to drive it at full resolution&refresh rate? -Daniel
Single-link cable is enough to empower LG 23MP65HQ-P as its standard resolution is 1920×1080@60, which is supported by single-link cable.
Dual-link cable comes with 27MP55HQ-P where it is required to provide higher resolution. BTW, in my previous email one should read "27MP55HQ-P" (not "23MP55HQ-P"). It is 27" monitor. Also, this monitor works with single-link cable (but at lower resolution, I guess).
