Best settings to render a HD wallpaper!

I made this scene to create a new desktop background for my Laptop but for some reason even when i render the image at the correct resolution (1366x768) the image doesn’t appear to look all that HD on my desktop (compared to the render).
Should i increase the resolution i render at or is they certain settings i have to change :)?


I think the best way to accomplish this is to render it at a very high res then put the image in gimp/photoshop downscale it to the resolution you are looking for.

Save it as a .png
