Sustained switching with autoscan

Front-panel buttons or hot-key commands change the active port instantly while the autoscan timer cycles through inputs at intervals from 1 to 99 seconds. LED indicators show which USB peripherals and which computer link are live at any moment.

Metal chassis with front and rear audio jacks

The unit measures 10.25 by 1.63 by 3.00 inches and weighs 4.72 lbs, providing a stable desktop presence. Console side duplicates the green audio jack on both front and rear panels for convenient headphone or speaker access.

Questions about this item

How much heat or fan noise does the GCS1794 produce when left on all day?

The unit draws 5.3 V DC from an external adapter and has no internal fan, so it runs silently with minimal heat buildup during continuous operation.

Which cables must I already have to connect four computers to the GCS1794?

Each computer requires an HDMI cable for video and a USB Type-B to Type-A cable for keyboard and mouse; stereo and microphone cables use mini-jack connectors.

Will the GCS1794 work with an older PC that only outputs 1080p over HDMI?

Yes, the switch supports 1080p and lower resolutions such as 720p and 480p, so legacy HDMI sources display correctly at their native resolution.
