Dell u3415w resolution of 3440×1440 and older machines [works]

February 14, 2016

2000557394The big question I had when buying the ultra wide-screen monitor with a 3440×1440 resolution is if my older machines would all support it.

– Dell Latitude 6430u
– MacBook Air Mid 2013
– Mac Pro 1,1 with ATI Radeon HD 5770

I could not find a definite answer, so I took the gamble and found out, they all work.
The Dell, can drive the monitor through HDMI as a second monitor. I found out that not extending the desktop, but using it as the single display benefits performance a lot.

The MacBook Air mid 2013 has no trouble driving the screen through the mini display port to HDMI or mDP. The mDP has the advantage of being 50Hz PAL or 60Hz NTSC, while HDMI is limited to 30Hz.

The Mac Pro 1,1 with the ATI Radeon HD 5770 drives the monitor without any problems using the mDP port to HDMI. I managed to run it ones using the mDP to mDP cable, but after sleep the screen did not wake up. Not sure what causes this, but through HDMI is works flawlessly.

The things that I’m still figuring out:
– there is a little backlight bleed in dark scenes in movies. See if it grows on me or not.
– the Mac Pro does not pass the sound through the mDP to HDMI connection. The Mac Book Air does and so does the Dell. So I’m trying to figure out why.

Just thought I’d share my results, for those of you trying to figure this out.

Finally some proof:
