Hi Guys.

Just a thought..

I'm using a u2711 as an external with my 2013 15" rMBP's Lid closed.
Would using intensive apps and heating up the rMBP damage the screen which is flat down on the keyboard?

Thanks :)

No, all Mac notebooks are designed to safely operate in clamshell mode without damage.
 
Mine is in clamshell mode 90% of the time sitting in a Bookarc. I only use the native screen and keyboard when I am on a photo trip for multiple days. Zero problems with that.
 
Okay, what the others are not saying, if with the initial 12 months or 3 years (apple care) your screen developed problems, be it operating in clam shell mode or note apple will replace your screen.

Go ahead and use it.

----------

Apple Warranty covers manufacturing defects. Operating in clamshell mode is not a defect, but an accepted mode of use for Apple notebooks.

No, but if the screen fails after operating in that mode, it's covered for the duration of warranty.
 
I use Clamshell mode when I play Elder Scrollls Online which requires high usage. No issues. But I do use a radtech cover on my keyboard to keep the keys and grease from getting on my screen. It also doubles as a cloth to clean your screen from smudges and specks.

Keep in mind, some people disagree with the usage of the cloth keyboard cover. I used it since my original retina came out in 2013 with no issues.

there is a known issue with the retina macbooks.

I posted about it here:

Basically, Apple were happy to replace my screen ONCE within the warranty and they recommend ALWAYS having somthing between the screen and keyboard when closed and generally keeping these things as clean as possible.

Hope that helps somewhat.
 
Doesn't the screen turn off when the lid is lowered beyond a certain angle? So unless here was something stuck in between the old and keyboard or some other mechanical impediment; I can't think of a reason why the screen could get damaged.

i was worried about heat from the main plate. the thing climbs to some high temperatures, and faces directly onto the screen

yeah, that is not the issue.

the screen can pick up grime and then burn it into itself.
