DP uses a smaller connector, smaller cable, uses a latch instead of annoying screws for retention, doesn't require dual-link outputs and cables for high resolutions (higher bandwidth). It can also carry audio. It's very similar to the latest iterations of HDMI but without the licensing fees.
The scaler is what adapts the input resolution to the screen's actual resolution. An LCD can only display its native resolution and nothing else--a scaler is required to run anything not native. That can be important when considering things like system POST, diagnostics, etc. Some video cards (and almost all of the last gen or two) have built-in scalers, but it's nice to not have to even worry about it. It's also nice to have some legacy inputs (e.g., d-sub) for special situations--and you don't normally find anything but a single digital input on screens that lack a scaler. -----Original Message----- From: hardware-boun...@lists.hardwaregroup.com [mailto:hardware-boun...@lists.hardwaregroup.com] On Behalf Of Anthony Q.

I have DVI and HDMI (IIRC). Is there some benefit to Displayport over these two? Bandwidth or something? What kind of vidcard drives two of these babies (with Displayport, I mean)? Also, what exactly is a "scaler"? Is this the feature that lets you view images at actual size (Quickfit)?
