 ==Display limitations== 

 Placing a video scaler before a limited-capability display device will not remove the limitations of that display device. For instance, you can't make a 720p display take a 1080p signal and expect to see all 1920x1080 pixels on the 1280x720 display surface; instead, the display will either scale the signal down or possibly crop the signal. A common misconception of consumers is that if you upscale from a 720p source to 1080p and the TV downscales to 854x480 internally (like within a plasma display), that you would end up with a better image. Since the final display surface does not contain the necessary pixel amount to display the 720p content in its entirety, there is a loss in the vertical and horizontal resolution in the final displayed image. It is preferred to send the display the exact resolution that it needs to output a final display image - even if the output device has more pixels than the source there will have to be blending of pixels or some sort of upscaling and this can cause problems. Some displays may have a further problem when displaying native resolution however; when sent the exact native resolution image, the display may be programmed to assume that it is receiving a signal from a PC (which causes some displays from manufacturers like Pioneer to reduce output brightness to avoid phosphor burn-in from a still image) or to crop off the overscan and zoom the rest.
