With DVI-only I wonder if they went bone-dead controller leaving out all the scaling and image manipulation...
Yes. I had that model, and you are correct in your assumption.
I've also had a U2711, and two ZR2740Ws.
With that said, I'm looking for a Catleap or similar again.
BTW, these use the panel from the Apple 27" display, and its only one digit off in model # from being same panel as u2711.
They are just the panels that Apple etc likely didn't want as far as QC goes.
The LG part number for the panel is LM270WQ1
