Unorderly ripples on the picture
It is usually caused by local interference, such as cars,
daylight lamps and hair driers. Adjust the antenna to
minimize the interference.

Perhaps the TV can not recognize the resolution set by
the PC. Suggest to change to the best resolution or other
standard resolutions of the Windows system.
Snowy dots and interference
If the antenna is located in the fringe area of a television
signal where the signal is weak, the picture may be marred
by dots. When the signal is extremely weak, it may be
necessary to install a special antenna to improve the
reception.
Other Information
1. Adjust the position and orientation of the indoor/outdoor
antenna.
2. Check the connection of antenna.
3. Fine tune the channel.
4. Try another channel. Broadcasting failure may happen.
Ignition
Black spots or horizontal streaks appear, or the picture
flutters or drifts. This is usually caused by interference
from car ignition system, neon lamps, electric drills, or
other electrical appliance.
