<p>Okay, so my question is, if you were to double the amount of pixels, and the resolution, wouldn't that be the perfect solution to upscaling? Or would that cause problems, but considering it would just be duplicating the amount of pixels instead of stretching them out, would there be possible issues with that? Or does that technology not exist yet? Or better yet would it be pointless?</p>
<p>Thanks for your answers! :)</p>

Is this upscaling algorithm in place already?
