Hello everyone, this is my first message on this forum and I wasn't sure which category to post it in.

I have a MacBook Pro with a native resolution of 1440x900 from 2012. I recently acquired a Samsung UHD monitor, which is almost at a native 4K resolution.

My question is the following: when connecting a device with a resolution of x to a screen with a better resolution of x, and then playing a 4K video, for example on YouTube or elsewhere, will the output on my UHD screen be at the resolution of my source device (in my case 1440x900), or will the output depend on the screen used regardless of the source (in my case, UHD screen)?

Assuming I have the necessary connections to handle 4K.

Hello,
it's the resolution of the screen being used that will be limited by what the graphics processor can handle, which is 2560x1600 over DisplayPort. It seems that it might be possible to achieve 4K but with a custom mode at 30Hz. On the 15-inch models equipped with a graphics card, it may support 4K at 60Hz (given that the GT650M graphics card supports 4K, but it's complicated with laptops).

So you think it's possible for me since I only have one mini display port?

I'm not sure, but in any case, it will be at least 2560x1600, which is not bad. The graphics card handles 4K natively, but on laptops, since the graphics card works with the integrated graphics (Intel HD 4000), I can't say what resolution it will output.

I think I just found the answer on Apple's site, thank you very much anyway :).
