a bit stupid about resolution(question)

[Arkosh]

if my laptop only can use 1366x768 resolution. then i have no different watch a video between 1080p and 720p, right?

because my laptop resolution limit the resolution of video, right?

[Paralectic]

There is a difference, you'll get a more sharp image and more pixels.

so if my laptop resolution lower then video resolution, i can still watch the more sharp image and more pixel on video?

example my laptop resolution only 720p then i want watch 4k video. i still watch "4k" resolution video on my laptop?

No there is no difference. You can look at 1080p and 720p on a 720p screen and you will notice no difference. It will just take longer for 1080p to load.

how about 4k video? this need new rig or just monitor?

[Sors]

Technically, the 1080p will look better, because your laptop have a resolution of 1366 x 768, so it can use a little more pixels than the 1280 x 720 resolution of 720p videos.  

 

But in reality, it would be hard to tell one from another in that display, so don't bother with the extra size of 1080p videos.

In some cases you get more quality out of it, take games and AA for an example. The game is rendered in higher resolution then the actual output, this is done in-order to make the image look smoother and remove jagged edges.

BF4 is a great example, as is ARMA 2/3, all of these games allow you to up the rendering scale beyond 100%, from what i have seen this actually makes the games look better, but also allot harder to tun.

I am not entirely sure if this will help in you-tube videos or similar, compression makes things difficult here.

depends if your video card can output 4k

you will only notice this difference when using a 4k monitor

Actually, every game can do it, depending on your hardware.  You can force the monitor to run higher resolution than the physical pixles (similar to overclocking it), but it makes it fairly useless outside of games. Also, it only really works with Vista or newer with AMD HD5000 or Nvidia Fermi or newer cards. With XP and before it forces the display to scale linearly, causing it to kind of scroll outside the native resolution. Intel drivers (at least on my HP DM3 laptop) do not allow higher refresh rates or resolutions, so can not say if that is an Intel issue, a CPU limitation, or a HP BIOS limitation (can't test on my desktop as it is P67.). 

This does the same thing you said, except it presents as a new resolution in the game options instead of a dedicated option. For example if you set it for double 1080p, you would get the option for 4k, but it would essentially be 4x the pixles for each native one. Works well for my desktop and ETS2, but I can test some more later if you would like.

I know most games have an AA feature, but the 3 in particular (or atleast ARMA 2/3) have the option to render the scene in 200% or 400% resolution, in ARMA it is 3D resolution, in BF4 it is just resolution scaling.

Also i am 80% sure that AA uses a certain algorithm, where as the methods available in these games use just brute lager resolution rendering.

We are talking about the same thing. Running the game in Overresolution,, lets say running 3840x2160 on a standard 1920x1080 monitor, it renders it at the higher resolution and then displays it out as the native. In the example above, you would set the game resolution (in settings) to 4k and the GPU would render at 4k, but you would see it compressed down to 1080p on the monitor. Just the method you are taking about has to be in teh game's settings to use it, while the one I am talking about will work with nearly every game (except some of the old DX8 and before that don't even allow 1080p/1200p in the game settings without modding.)

Yeah, i didn't read you first reply thoroughly enough, sorry.

Anyhow, on topic, you could get some benefit out of watching 1080P because i think that will make the compression artifacts show up less. More bit-rate, same resolution, try it and see if it will help.

Yep.

As for the OP's question (which I forgot to address. Stupid me), it will not do anything but good things to stream at 1080p on a 768p monitor, assuming of coarse your Internet is fast enough. All  you will basically have is some level of AA in the rendered image (the video), while running 720p will have some of the pixles doubled, and thus a blockier image.
