The VP-420/VP-421 PC/HD Scaler also features:

•An On-Screen Display (OSD) for easy setup and adjustment, accessible

via the front-panel buttons

•A built-in ProcAmp for convenient signal adjustment

•A non-volatile memory that retains the last settings used

•Quick auto-adjust

Operate your VP-420/VP-421 directly via the front panel push buttons and

the on-screen display (OSD).

To achieve the best performance:

•Use only good quality connection cables1

•Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer

to avoid interference,

deterioration in signal quality due to poor matching, and elevated noise

levels (often associated with low quality cables)
