A qualified support


in all service areas is just as much a matter of course for us as the comprehensive advice provided by our sales department. For G&D, this is part of the basis of a functioning partnership.

Telephone support

Our service technicians are just a phone call away, and in many cases can resolve the issue over the phone.

Fast repair service

If telephone support is unsuccessful, you can send the equipment to us for repair. 

Free Estimate

There is no warranty claim?  We will provide you with a free estimate for the repair or replacement.

On-site option

In individual cases, a qualified specialist is also available on site to fix the problem of the equipment.

G&D Warranty

Three-year full manufacturer's warranty


for all G&D KVM devices, which thus far exceeds the legal range

Repairs and returns for our devices

Product changes and discontinued products

We continuously optimize our product portfolio in order to be able to offer you fast availability, replacement security and a solution competence in line with the market. Even for discontinued products, we can usually still provide you with support or repair the devices. In such a case please contact our support. To find out whether your product is affected by a product discontinuation, please refer to the list.
