DVI can output at up to UXGA 1920 x 1200 at 60 Hz, the standard refresh rate, but requires a second connection (aka, dual-link DVI) to power a 2K or 4K monitor. Fortunately, you can easily get an adapter to go from your computer's HDMI or DisplayPort to DVI. Often, DVI will be your best input option as many budget and mainstream displays have only DVI and VGA connectors. Unpowered DisplayPort-to-HDMI cables won't work.Īlso Known As: DVI-D, DVI-I, Dual-Link DVI Description: While you'll never see a laptop with DVI (digital visual interface)-out, almost every monitor with a full-HD resolution or below has one, and so do many desktops. If you want to go from an HDMI port on your computer to a DisplayPort on your monitor, you'll need a rather-pricey active converter that requires its own power connection and that costs over $30. For around $25, you can get an adapter that goes from USB Type-C to HDMI (opens in new tab), provided that your Type-C supports video.
Adapters Needed: If you need to connect to DVI, an HDMI-to-DVI plug (opens in new tab) costs under $10. These are a bit smaller, and it's more difficult to find adapters for them. While most laptops that have HDMI use the full-size port, there are a few superslim devices that employ mini HDMI connectors. If your computer has HDMI-out and your external display has DVI, you can convert from one to the other with an adapter that costs less than $10.

However, you cannot output to dual displays from a single port. Depending on your laptop's or desktop's graphics card, the machine's HDMI (high-definition multimedia interface) port may be able to output at up to 4K resolution. £86 (opens in new tab) at Amazon (opens in new tab)ĭescription: This popular port is the most common one for connecting to TVs and also appears on many external monitors and projectors.
