According to one embodiment, a video display device includes a super resolution converter, a moving-image improving module, and a demonstration mode controller. The super resolution converter performs, on receipt of a first video signal with first resolution, super resolution conversion on the first video signal to obtain a second video signal with second resolution that is higher than the first resolution. The moving-image improving module performs moving-image improvement on the second video signal to double the frames of video per second. The demonstration mode controller controls activation of first demonstration mode for displaying, on a display module, demonstration related to the super resolution conversion and second demonstration mode for displaying demonstration related to the moving-image improvement.
