(Nvidia's RTX series supports HDMI 2.0b, which is necessary for displaying Hybrid Log Gamma HDR, which is currently only really relevant at the moment if you're editing HDR video.)

On the graphics card side that means Nvidia GeForce GTX 1050 (i.e., Pascal) and AMD Radeon RX 400 series or newer cards. HDR display requires DP 1.4 or HDMI 2.0a (or later).Mini DP, occasionally found on gaming laptops, and USB-C Alt Mode are DP 1.4 USB-C with Alt Mode support is actually the successor to Mini DP.It's not automatically supported, though, so check the monitor specs. The number of monitors depends upon their resolutions and you'll most likely need a splitter or hub. DP 1.2 and later supports daisy chaining, allowing you to drive more than one monitor off a single output connection.In other words, if your graphics card uses DP 1.4 but your monitor is DP 1.2, you won't get HDR. If a feature requires a specific version of one of the standards, that means that both the monitor and the graphics card need to have it.

If you'd like to make up your own mind, though, here some considerations to take into account: For instance, some HDMI dongles and hubs with HDMI connectors, notably the cheap ones, can't display 4K at 60Hz, only 30Hz. (For multi-computer setups - connecting two computers to a single monitor - the connection type matters less than the features of the monitor.)ĭongles are sometimes a necessary evil, but avoid them if you can: They're easily lost and don't always work properly, or at least as you expect. Depending upon your graphics card you may only have one of each connection type or USB-C only, anyway, and if you're forced to daisy chain the USB-C DP it may limit the resolution options. Multiple monitorsįor multimonitor setups, you might want (or need) both.

Color workįor color-critical work either HDMI 2.1 or DP 1.4 have enough bandwidth to handle an uncompressed data stream, especially at 4K. You need to check specifically that the monitor's or TV's specs for HDMI 2.1 explicitly state that they do, at the resolution(s) you care about. To support variable rate refresh (VRR) on the Xbox Series X/S, and forthcoming on the PS5, as well as dynamic HDR metadata ( HDR10 Plus) for better HDR rendering, you can't assume that a monitor with an HDMI 2.1 connection automatically supports them. DP is obviously better if you've got an Nvidia card and want to use G-Sync FreeSync may be better over DP as well.įor consoles, you really don't have a choice - they only support HDMI - but you have to pay attention to not just the version of HDMI, but the specific list of features it supports.
WHICH VIDEO CARD FOR 4K TV UPGRADE
If you're trying to pick a monitor, HDMI is the budget-friendly choice, but if you've got DP you'll have more options if you plan to upgrade to a new graphics card or add an external GPU in the near future. HDMI tops out at 144Hz uncompressed or 240Hz compressed, while DP 1.4 can hit 360Hz in 1080p. If you've already got a monitor with a DP 1.4 connector and a matching graphics card, then use the DP, simply because it gives you the most ways to configure adaptive refresh and at the moment supports the highest refresh rates. There really are no easy answers, because that opens the " AMD vs. Any laptop that's light enough to tote everywhere doesn't have a DP connection, anyway. You may want to ensure your laptop has a built-in full-size HDMI connection as well, though they're getting scarce while you can use USB-C-to-HDMI or micro HDMI-to-HDMI dongles, they're easy to lose and you don't want to spend the first 20 minutes of your meeting time hunting for one. That's the most pervasive connection type. If you travel for business and want to hook up to monitors in different locations, it's HDMI all the way (and version doesn't really make a difference).

You're probably better off with HDMI, in general, simply because monitors with DisplayPort (DP) in addition to HDMI tend to be more expensive.īut if you're one of the edge cases where you do need to think about it - for console or PC gaming, color-critical work, business travel or multimonitor configurations - here are some guidelines. For general-purpose use - and a single 4K display is no longer a special case - then it doesn't matter.
