Hi there, Problem description: I just got a new monitor that the office next door was getting rid of, a Benq GW2765HT. When the monitor is plugged into the mobo via DVI it works fine, although can't display 1440p. Plugging in the monitor to the GPU via DVI-HDMI works fine for 1080, but when I try to change the resolution to 1440 the screen blacks out and then returns when it automatically reverts back to 1080. Attempted fixes: I've tried a variety of cables including an HDMI/HDMI cable, HDMI/DisplayPort, and used an active HDMI female>DisplayPort male adaptor, all of which just give a black screen. I've even tried using the DVI-HDMI with the DisplayPort adaptor (which seems excessive) and again this works fine for 1080, but not 1440. Drivers and Radeon software are up to date as far as I can tell. I'm not ruling out that the monitor itself could be faulty. Recent changes: Nothing apart from a recent Windows update, just added the new monitor. Any help appreciated, thanks  -- Operating system: Windows 10 64-bit System specs: CPU: i5-6600 Mobo: ASRock Z170 Pro 4 LGA1511 Memory: Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-3000 GPU: Radeon RX 480 8GB PSU: 600W Antec Location: Australia I have Googled and read the FAQ: Yes

I think you need dual link DVI or display port. I think in spec HDMI doesn't support 2560, though some monitors and videocards might be able to break the spec without issue.
