Does a laptop's attached screen resolution differ from it's external display capabilities?

I have a new ASUS G750 laptop with a 3GB GTX770M video card and I'm looking to get an external monitor to hookup. When I'm using my actual laptop screen and not an external monitor the maximum option for the resolution is 1920x1080. The monitors I'm looking to purchaseare 27" with resolutions listed at 2560x1440. I'm thinking that maybe once I plug in a higher resolution external monitor that I'll have the option to bump up the resolution past the 1920x1080 limit on my laptop screen but I'm not positive. Here are the two monitors I'm looking at:

When I look at the Nvida website I find this:

Display Support:
Yes H.264, VC1, MPEG2 1080p video decoder
Up to 3840x2160 LCD – eDP 1.2 support
Up to 1920x1200 LCD – LVDS support
Up to 2048x1536 VGA analog display Support
Up to 3840x2160 DisplayPort Multimode Support
Yes HDMI
Yes HDCP content protection
Yes 7.1 channel HD audio on HDMI
Yes TrueHD and DTS-HD Audio Bitstreaming

Here's the website: http://www.geforce.com/hardware/notebook-gpus/geforce-gtx-770m/specifications

I'm trying to be POSITIVE that the external monitor will work optimally with my laptop. My laptop has a thunderbolt port so I'd probably use a minidisplay->displayport cable to connect them. Can anyone with some more expertise help me get this figured out?

Ah yes, I've done that before, but I'm curious if the external display will be able to support the larger 2560x1440 with a crystal clear no-compromise display or if I'm capped at the laptop screen's 1920x1080 resolution for quality images. I plan to show the desktop on only the external display when it's plugged in if that matters at all.

How did this work out for you? I'm in a similar situation and want to be sure my GeForce GTX 860M can power a 2560 x 1440 @ 60Hz monitor.

I actually went with a smaller monitor in the end, but I found out the output display through the external ports is typically higher than the resolution on the laptop screen. I looked up your monitor and found this:

Up to 3840x2160LCD – eDP 1.2 support
Up to 1920x1200LCD – LVDS support
Up to 2048x1536VGA analog display Support
Up to 3840x2160DisplayPort Multimode Support

That is from the GeForce website: http://www.geforce.com/hardware/notebook-gpus/geforce-gtx-860m/specifications

So as long as you're using one of the newer connection types like display port you should be okay since 2560x1440 is the same ratio as 3840x2160. At least that is how it seems to me, looks like a pretty safe bet but maybe somebody else can chime in.

Thanks for the info!

Yeah, here's my own post:

Long story short: I have a Thunderbolt 1 port, but I'm using it for an audio interface so it's unavailable for a monitor. Therefore, I have to use my HDMI port. You can see my logic in my post, but it *looks on paper* like that should work. As a subsequent poster said, however, I won't know for sure until I try it. Which is really irritating, because I've already spent a lot of money failing to get my previous monitor to work when on paper it should have worked. :)

Ah I see you found about the same info. Frustrating isn't it? I think the HDMI port should work fine but I would buy it somewhere with a good return policy like Amazon or if available Costco so you can exchange it for another one should it not work.

Very! :) Nice to know I'm not alone, though.

Thanks for the vote of confidence and very good point about buying it with the store's return policy in mind.
