As there are different connectors for different countries, we don’t ship power adapters. Our products always support a wide range of DC power inputs, and we use standard DC power connectors. You can easily purchase a power adapter in your local market.
For industrial computers, a power adapter is not essential because our products are part of the customers’ machines that always have their own power.

The software can cut down the resolution, but cannot increase it.
