HDMI might work for you, but as the manual for the monitor states: (It goes over a single cable, just means a somewhat pricier cable.) That's why they recommend dual-link DVI for higher resolutions. Asus bought a cheaper part, because most people aren't trying to use VGA at 2560x1440.ĭVI is limited by its spec to a max of widescreen 16:10 ratio of 2,098 × 1,311 because it just can't signal fast enough. The higher the resolution on VGA, the better the analog circuitry in the monitor needs to be in order to extract the signal. VGA on the PB278Q is limited to 1080p by the monitor's circuitry (check out the manual). What resolutions would I get with a third-party miniDP to DP cables or adapters, or miniDP to HDMI? What is the maximum resolution of Mini DisplayPort to Dual-Link DVI adapter as ordered for mid-2013 MacBook Air 13?ĭoes Apple's official HDMI adapter, "Belkin Mini DisplayPort to HDMI Adapter", support "resolutions above 1920x1200"? Which ones would that be? Why resolutions of Mini DisplayPort to VGA and DVI adapters is limited to 1920x1200?
I'm not aware of VGA being limited to 1080p, and this is not advertised at all anywhere on the ordering page.Īs per Google search of Apple's quite scattered and incomplete docs on the matter, which, in the end, still don't cover all custom-order options provided immediately on the ordering page for a MacBook Air, both VGA and DVI adapters apparently only support up to 1920x1200 resolutions, with dual-link DVI being required for "resolutions above 1920 x 1200" (what does this even mean, I'm buying a MacBook Air, what's "above 1920x1200"?). A mini DisplayPort to DVI adapter is also available from Apple.Īn ASUS PB278Q 27" 5ms WQHD (2560 x 1440) only gets 1920x1080 resolution using the VGA adapter. I've got a new 2013 MacBook Air 13", with Intel HD Graphics 5000, and it came with a Mini DisplayPort to VGA adapter within the box.
