Hi Kcnyc,

Thank you for posting on the forum.

Are you using an external or internal usb cable?

Using the internal one.

It looks like you may have an interference problem. Try routing the cable close to your case to ground as much noise as possible. If you test out the display with an external usb cable, you would notice the problems will disappear. You can also pierce the shielding and tack it onto your case, if you want to eliminate the noise.

Let me know how these suggestions work out for you.

Best Regards,

Do you think wrapping the internal cable with aluminum foil will work?

Wrapping the cable with aluminum foil won't help because there is shielding already, but the shielding isn't grounded to earth ground or chassis ground. If you have it connected to chassis ground the electrical noise just goes to ground.

So basically cut abit of the rubber cladding of the cable and connect it to the casing? I will try that.....thanks Tom.
