Does scaling vertically affect horizontal quality.

Since computer monitors do not have a 1080 lines native resolution, a 1080 feed will have to be scaled. If this signal is being scaled anyways, does it really matter if the display has a horizontal native resolution of 1920. I am wondering if there will be a noticable drop in performance by buying a screen with a native resolution of 1050 X 1680 instead of 1200 X 1920 or a 1080 X 1920 TV with a PC input.

Not true. With the proper scaling setting, you will just get black bars on the top and bottom of the screen.
 
saiyan, you have totally lost me, how do display 1080 lines on a screen with less than that, without losing on the resolution and also losing on the process of scaling it.

It means if its set to scale back in orginal size, it will have black bars.

In this case, a Dell 2405 with a 1080i VGA signal will look pretty close to this. Note the black top and bottom as the Dell is a native 16:10 not 16:9 resolution in widescreen

I'm lost on your question.

It comes down to if your display's native resolution is less than the source, it's going to lose quality. There's nothing you can do about it.

How much quality gets lost? That would be subjective.

I should have said if you use a monitor with native 1920x1200 resolution, you should not worry about displaying 1920x1080 video.
