An upscaled image is stretched. So detail is not as fine as a native image at the same resolution. Open MS paint, paste a 1280 x 760 image, any image. Then select resize and change the pixels to 1920 x 1080. Notice how much more blurry those pixels become. Granted most TV's have a program to help reduce that blurryness and sharpen the image but it's still not as clear and sharp as a native 1920 x 1080 image. |
Yes, I should have added this to my explanation: an image upscaled in a cheap, unrefined way could actually lose quality, some kind of not too coarse interpolation, even better some smoothing and antialiasing is needed to at least enjoy some advantages of higher res, even without the higher detail of native higher res.
