The hardware brochure says "HDMI 2.0 (3840x2160 @ 60Hz), HDCP compliant" on

So the only reasons I can think of for 2560x1440 (which requires only HDMI 1.3) being rejected are:

1. Low quality HDMI cable. Make sure you use a cable that is advertised as supporting 4K. HDMI 1.3 can do 4K at 30Hz and HDMI 2.0 can do 4K at 60Hz.

2. A buggy TV/display returning bad EDID data. That's unlikely but happens occasionally.
