Just a couple of question on DSR and real resolution monitor above 1080p.

If I have DSR enabled and at 1440p on the desk top everything is really small. Games are perfect and can even turn off anti aliasing to save on resource and AA don't make that much difference with DSR. Any way if I got a 1440p or above does the text and icons etc come really small like with DSR?.

Is there much difference between Nvidia DSR and real 1440p plus resolution?. On my 970 GTX if I want max setting in games with AA turned off I can have 1440p DSR MAX. Above this it starts to stutter.

Thanks.

I only have 1440p set in games not desktop I have my desktop at 1080p. But if I it set to 1440p on desk top then I cons etc come really small. Just wanted to no if real native monitors do this also.

Using DSR on the desktop doesn't make any sense. As you said it'll just make things smaller like changing Windows scaling. A 1440p pane will have smaller icons than a 1080p pane of the same size but you can change Windows scaling to make them bigger.

DSR is just super sampling AA. True 1440p will give much more detail than using DSR at 1440p on a 1080p panel. 1440p has nearly twice the pixels of 1080p.

Icons are a fixed size eg 75 x 75 pixels.
So on a 26" 2560x1440 the icons will appear smaller than on a 26" 1920x1080 display.

If you want to make your icons and text bigger again ( assuming you are using windows 7 and up) right click on the desktop and select personalise click display from the left.
either use the slider "smaller >>>>>Larger" or put a tick in the "let me chose one scaling level......." then click "custom sizing options" and select your own percentage you wish to enlarge by.
 
DSR doesn't represent the clarity of really having that resolution so while stuff is smaller it is clearer than you'd see with DSR.

DSR is a little more complex than just super sampling AA (which is more the focus of VSR) - DSR has some semi-intelligent filtering to try and preserve detail that would normally be averaged out even with advanced versions of normal super sampling techniques.

People often equate DSR and VSR as being the same but they actually are a little different - VSR is much more like super sampling where its biggest benefit is in making the edges of stuff look nicer as if you had higher resolution while DSR is more focused (relatively speaking compared to VSR/generic downsampling) on trying to preserve detail within an area and doesn't bother itself as much with edge filtering (which happens naturally to a degree with those kind of systems anyhow) - though part of the system does handle edges as well.

If a 1440p monitor and a 1080p monitor are the same size then icons will appear smaller on the 1440p screen because the pixels themselves are smaller. As Minstadave said though, you can get around this by adjusting Windows scaling to make them larger. If you take into account the fact that 1440p screens are usually bigger than 1080p screens, the size of icons usually isn't such a big issue.
