Display Questions

[iNewbie]

Hi,

2 quick display related questions... 1 internal and 1 external

On the new retina models, if you're in 1400x900 or 1680x1050 mode for instance, it's using scaling, but what happens if you do a screen capture? either still graphic, or a region as part of a screencast. If I draw a box that should be 1280x720 is that what I would get or would it include all the "unscaled" pixels?

I'm worried that it would include all the unscaled pixels and would just be a problem until software like screenflow/snagit gets updated and who knows how long that might be.

As such, I'm thinking about getting a new non-retina MBP - hi-res anti-glare. My question there, is if I want to attach it to an external monitor, will it work with the NON thunderbolt 24 inch LED monitor? That was display port only. I thought the first thunderbolt machines didn't work with it.

Assuming it does, could I add a new thunderbolt monitor and chain to the 24 inch LED to get two external monitors running from the laptop? That would be my goal really - to get up to at least the 2 monitors from the laptop.

Any advice would be appreciated. Thanks

If you are in the scaled 1400x900 mode (really 2880x1800), the screen grab will be 2880x1800, or in your case of the box, it would be 2560x1480. You could quickly reduce it to half its size using preview or something like that. I have been using a command line utility I found (setres) to set the screen to actual 1400x900 (or acutal 2880x1800), when I want to test something with a 1:1 scaling factor. When I take a screen shot then, I get the expected size.

Thunderbolt is backwards compatible with display port, so you can use a display port monitor.

The screenshot will be double the resolution (both width and height) of the "Looks Like" setting. "1440x900" mode will produce 2880x1800 screenshots. "1920x1200" mode will produce 3840x2400 screenshots.

Because of the way Thunderbolt works, you would need another Thunderbolt device (like a hard drive) between the Thunderbolt display and the mini-displayport monitor.

To daisy chain two displays with nothing in between you would have to have two Thunderbolt displays.

Since the Retina MBP has 2 Thunderbolt ports and an HDMI port, you can hook up two mini-displayport displays (or mini-displayport adapters) and an HDMI display without any Thunderbolt daisy chaining.

Ok. thanks! so if I'm understanding you correctly i can hook up to the non thunderbolt monitor (apple 24 LED) directly but can not chain unless there's a thunderbolt device in between a thunderbolt and the LED...

Do I have that right?

Yep. If you want to run two displays off of one TB port there are two ways:

Computer->TB Display->At least one TB device->Mini-Displayport

Or

Computer->TB Display->TB Display

Thanks for the advice. Very appreciated!
