Subject: HDMI 2 on z170 ITX stopped working completely
Posted: 25 Oct 2016 at 9:48pm
I bought the board specifically to drive two 4k displays at 60hz (one on display port, one on HDMI2). This never worked on HDMI2 (no problem with display port). I am using stock HDMI cable supplied with the 27UD68-w monitor. 30hz has been the best I could do.
I flashed to latest BIOS, no change. loaded latest HDMI firmware (the one it defaults to in case there are more), no change. Now, suddenly, HDMI2 stopped working altogether, and when I try to load the firmware again, the loader says "ISP failed" or something to that extent.
Please help.
