The ATEN CE790 Digital KVM Extender is an IP-based keyboard, video and mouse (KVM)\u00a0appliance that supports full HD video\u00a0and connects to\u00a0USB keyboards and USB mice. The CE790\u00a0gadget\u00a0also\u00a0has mic in, audio out and RS232 serial ports for\u00a0use along with\u00a0remote computer systems over local Ethernet-based networks.\n\tThe CE790 consists of\u00a0one transmitter (CE790T) unit and a receiver (CE790R) unit, each of which\u00a0is powered\u00a0via the included AC adapters. The device is rugged and well built,\u00a0and its chassis is made of anodized steel.\n\tFor my tests, I connected the CE790T to my laptop using a custom KVM cable that comes with the device and combines the various cables into a single bunch. Next, I connected the\u00a0CE790T and CE790R using a single CAT5e network cable. No\u00a0further configuration was needed. The CE790 also operates over a network switch,\u00a0which means\u00a0both ends of the KVM\u00a0could be\u00a0hundreds of meters part.\n\tVideo at 1080p (1920 x 1080) was smooth on\u00a0my Windows desktop.\u00a0My mouse was also responsive with no "ghosting" effects even when I\u00a0moved it very\u00a0quickly across the screen. Text looked a tad fuzzy, though it was\u00a0still perfectly readable. When I played a couple of movies\u00a0a few frames skipped during\u00a0rapidly-changing scenes. The skipping wasn't too bad,\u00a0but it could make the CE790 unsuitable as a media extender.\n\tThe CE790 is powered by a specialized ASIC (Application-Specific Integrated Circuit), which digitizes incoming signals prior to transmitting\u00a0them through the network. This was probably the reason why\u00a0the unit\u00a0got disturbingly hot after an hour or two of use.\n\tThe CE790\u00a0also\u00a0lets you\u00a0broadcast to multiple CE790R devices, but you'll need to purchase additional hardware to do so.\n\tBack view\u00a0of the ATEN CE790 Digital KVM Extender. Note the mouse port can only be used with a USB mouse, and the keyboard port can only be used with a USB keyboard.\n\tClose-up front view of the ATEN CE790.\n\tThe cables come in a single bunch for manageability.\n\tConclusion: ATEN CE790 Digital KVM Extender\n\tThe\u00a0ATEN CE790 Digital KVM Extender can be used for a number of purposes,\u00a0including remote\u00a0connection to a desktop or server located in another part of the house or office. Its Ethernet\u00a0support and the ability to work over standard intranet infrastructure makes it\u00a0easy to stash noisy machines in a more isolated part of the house.\n\tUnfortunately, its lackluster video capabilities mean you won\u2019t be able to use it as the multimedia extender device.\u00a0And its $780 price tag is also a bit of a turnoff.
