Image display device

An image display device, comprising:

• an image output unit for displaying an image represented by an image signal;
• an amplifying unit for amplifying said image signal with a gain having a frequency characteristic and supplying said amplified image signal to said image output unit, including a variable inductor, an inductance of which defines said frequency characteristic;
• and
• a control unit for controlling said inductance of said variable inductor, wherein
• said image display device receives a synchronizing signal of said image, and further comprises a resolution detection unit for detecting a resolution of said image signal on a basis of said synchronizing signal;
• and
• said control unit varies said frequency characteristic depending on said resolution.
