Switching to HDMI alleviated the problem and my screen ran at its native 2560×1440 pixels - though the colors were all messed up because the computer was outputting YCrCb while the screen was interpreting that as RGB, but that is easily fixed by creating an EDID override.
I first hooked it up via mini-DisplayPort and was disappointed to find that it only runs up to 2048×1152 pixels. HDCP-encrypted HDMI works fine, as confirmed by starting a Netflix video.

VGA and HDMI run up to a resolution of 2048×1152 pixels at 60 Hz (even though Dell says it only supports 1920×1080), Ethernet works without installing a driver (it contains the same Realtek chip, PCI ID 0bda:8153, that the official Belkin USB-C adapter uses). Note that it connects to the computer via Thunderbolt 3 instead of USB-C, which means it can deliver higher screen resolutions (see below).įirst of all, the DA200 just works. It also passes power through to the computer.ĭell TB15: This model appears to have been recalled because it didn’t run stable and replaced with the TB16.ĭell TB16: stationary device shaped like a stack of a dozen CD cases, with a 180W or 240W power brick. Over the DA200, it adds mini-DisplayPort, 2x USB2, 2x USB3, Speaker and Headset outputs. Dell’s XPS 13 and 15 series however has included Thunderbolt 3 for a year now and Dell makes some nice docking stations for them:ĭell DA200: small portable device with Gigabit Ethernet, USB 3, VGA and HDMI.ĭell WD15: stationary device with a size similar to a paperback book, with a 130W or 180W power brick. Belkin has announced the Belkin Thunderbolt 3 Express Dock HD, but it seems like it will be priced upwards of $300. These ports are great because they can carry power, USB and output to an external display simultaneously. Not a lot of accessories are available on the market yet though besides simple adapters from USB-C to things like USB, HDMI, VGA, Thunderbolt 2, or Ethernet. I recently got a new MacBook Pro with Thunderbolt 3 ports.
