Which Port?


Which Port?

Ask the Doctor LogoThanks to Maximum PC’s past advice, I have a new rig with an ATI Radeon HD 5870 graphics card. It has dual DVI, HDMI, and DisplayPort connections. I use my rig for photography and video editing. I have a 24-inch Dell monitor with all of the above ports. Which is the best one to use and why?

Based on what we know of Dell’s 24-inch monitors, it doesn’t matter which connection you use, and will mostly depend on which cable you have handy. If you had a monitor with built-in speakers, you would want to opt for HDMI, which carries both a video and audio signal. It’s also true that monitor makers don’t always include HDCP (High-Bandwidth Digital Content Protection) on all ports—HDCP is necessary for watching copy-protected Blu-ray movies—in which case, you would also want to opt for HDMI, which offers that feature. But in the case of Dell’s 24-inch monitors, it’s our understanding that HDCP is present in all ports.
