FAQs

Why does the image of an analog signal look blurred even if I adjust the clock and phase?

With an analog connection, the higher the resolution the more the signal degrades resulting in blurring of images and text. Thus, we recommend you use a digital cable if your monitor will display a resolution of 1920x1200 or more.
