Device Port Lookup
Look up which video ports a console, streaming box, Mac, or graphics card actually has, the highest resolution and refresh rate it can output, and the cable grade that output needs. Search by name or filter by category.
| Device | Video ports | Maximum output | Cable it needs |
|---|---|---|---|
| Game consoles | |||
| PlayStation 5 / PS5 Slim 2020 | 1 x HDMI 2.1 | 4K at 120 Hz; 8K at 60 Hz with DSC | Ultra High Speed HDMI Supports VRR and ALLM. The Ultra High Speed cable in the box is required for 4K at 120 Hz - an older High Speed cable caps the console at 4K 60 Hz or drops the signal. |
| PlayStation 5 Pro 2024 | 1 x HDMI 2.1 | 4K at 120 Hz; 8K at 60 Hz with DSC | Ultra High Speed HDMI Same output ceiling as the PS5; the gains are in rendering, not in the link. |
| PlayStation 4 Pro 2016 | 1 x HDMI 2.0b | 4K at 60 Hz, HDR10 | Premium High Speed HDMI No VRR. 4K 60 Hz HDR fits comfortably in HDMI 2.0's 18 Gbit/s. |
| PlayStation 4 2013 | 1 x HDMI 1.4 | 1080p at 60 Hz | High Speed HDMI Any working HDMI cable of this era is sufficient - there is nothing to gain from a higher grade. |
| Xbox Series X 2020 | 1 x HDMI 2.1 | 4K at 120 Hz; 8K at 60 Hz | Ultra High Speed HDMI Supports VRR and ALLM. Ships with an Ultra High Speed cable; keep it with the console. |
| Xbox Series S 2020 | 1 x HDMI 2.1 | 1440p at 120 Hz (4K upscaled output) | Premium High Speed HDMI or better The port is HDMI 2.1, but the console targets 1440p rather than native 4K, so the bandwidth demand is well below the port's ceiling. |
| Xbox One X 2017 | 1 x HDMI 2.0b out, 1 x HDMI in | 4K at 60 Hz, HDR10 | Premium High Speed HDMI The second HDMI port is an input for passthrough, not a second display output. |
| Nintendo Switch (dock) 2017 | 1 x HDMI 1.4 (on the dock) | 1080p at 60 Hz docked | High Speed HDMI Video only reaches a TV through the official dock; the console's own USB-C port does not drive a display on its own. |
| Nintendo Switch 2 (dock) 2025 | 1 x HDMI 2.1 (on the dock) | 4K at 60 Hz docked; 1080p/1440p up to 120 Hz | Ultra High Speed HDMI As with the original Switch, the dock provides the HDMI output. |
| Steam Deck 2022 | 1 x USB-C (DisplayPort 1.4 Alt Mode) | 4K at 120 Hz or 8K at 60 Hz with DSC | USB-C to DisplayPort or HDMI, or a dock There is no HDMI port on the device. Use a USB-C to HDMI/DisplayPort cable or a dock - and a full-featured USB-C cable, not a charge-only one. |
| Streaming & media players | |||
| Apple TV 4K (3rd generation) 2022 | 1 x HDMI 2.1 | 4K at 60 Hz, Dolby Vision and HDR10+ | Premium High Speed HDMI or better No cable is included in the box. 4K 60 Hz HDR does not need an Ultra High Speed cable, though one does no harm. |
| NVIDIA Shield TV / Shield TV Pro 2019 | 1 x HDMI 2.0b | 4K at 60 Hz, Dolby Vision and HDR10 | Premium High Speed HDMI HDMI 2.0b, so 4K is capped at 60 Hz regardless of what the TV supports. |
| Chromecast with Google TV (4K) 2020 | 1 x HDMI 2.0 | 4K at 60 Hz, Dolby Vision and HDR10+ | Premium High Speed HDMI The HDMI lead is attached to the device. |
| Roku Ultra 2024 | 1 x HDMI 2.1 | 4K at 60 Hz, Dolby Vision and HDR10+ | Premium High Speed HDMI or better Streaming content tops out at 4K 60 Hz, so the port version matters less than the HDR format support. |
| Apple Mac | |||
| MacBook Pro 14" / 16" (M3 and M4 family) 2023-2024 | 1 x HDMI 2.1, 2-3 x Thunderbolt 4 or 5 | 8K at 60 Hz or 4K at 240 Hz over HDMI; up to 6K at 60 Hz per Thunderbolt display | Ultra High Speed HDMI, or Thunderbolt / USB-C to DisplayPort The number of external displays supported varies by chip tier - base M-series chips drive fewer than Pro and Max versions. |
| MacBook Air (M2 / M3 / M4) 2022-2025 | 2 x Thunderbolt / USB4 (no HDMI) | Up to 6K at 60 Hz per external display | USB-C to DisplayPort cable, or USB-C to HDMI adapter There is no HDMI port on any MacBook Air. External display support differs by generation: the M2 drives one, while later models can drive two. |
| Mac mini (M4 / M4 Pro) 2024 | 1 x HDMI 2.1, 3 x Thunderbolt 4 or 5 | 8K at 60 Hz or 4K at 240 Hz over HDMI | Ultra High Speed HDMI, or USB-C to DisplayPort Supports multiple simultaneous displays across the HDMI and Thunderbolt ports. |
| iMac 24" (M3 / M4) 2023-2024 | 2-4 x Thunderbolt / USB4 (no HDMI) | One external display up to 6K at 60 Hz | USB-C to DisplayPort cable, or USB-C to HDMI adapter No HDMI port. The built-in screen counts toward the display limit. |
| Graphics cards | |||
| NVIDIA GeForce RTX 50 series 2025 | 3 x DisplayPort 2.1b (UHBR20), 1 x HDMI 2.1 | 4K at 480 Hz or 8K at 165 Hz with DSC | DP80 certified DisplayPort, or Ultra High Speed HDMI UHBR20 needs a DP80 certified cable - an older DP8K cable silently limits the card to HBR3 rates. |
| NVIDIA GeForce RTX 40 series 2022 | 3 x DisplayPort 1.4a, 1 x HDMI 2.1 | 4K at 240 Hz with DSC over either port | DP8K certified DisplayPort, or Ultra High Speed HDMI These cards are DisplayPort 1.4a, not 2.1 - a common point of confusion. HDMI 2.1 is the higher-bandwidth output on this generation. |
| NVIDIA GeForce RTX 30 series 2020 | 3 x DisplayPort 1.4a, 1 x HDMI 2.1 | 4K at 120 Hz; higher with DSC | DP8K certified DisplayPort, or Ultra High Speed HDMI Check before buying a passive DisplayPort adapter - recent NVIDIA cards have dropped dual-mode (DP++) support, so passive DP-to-HDMI and DP-to-DVI adapters may not work. |
| AMD Radeon RX 9000 series 2025 | DisplayPort 2.1a (UHBR13.5), HDMI 2.1b | 4K at 240 Hz with DSC | DP40 certified DisplayPort, or Ultra High Speed HDMI UHBR13.5 sits between HBR3 and UHBR20; a DP40 cable covers it. |
| AMD Radeon RX 7000 series 2022 | DisplayPort 2.1 (UHBR13.5), HDMI 2.1 | 4K at 165 Hz or 8K at 60 Hz | DP40 certified DisplayPort, or Ultra High Speed HDMI Exact port mix varies by board partner - check the specific card. |
| Intel Arc B-series 2024 | DisplayPort 2.1 (UHBR13.5), HDMI 2.1 | 4K at 180 Hz with DSC | DP40 certified DisplayPort, or Ultra High Speed HDMI Port mix varies by board partner. |

How to check the ports on your own device
- Look at the port itself. The Connector Identifier works out which connector you are looking at from its shape.
- HDMI version is not printed on the port. There is no way to tell HDMI 2.0 from HDMI 2.1 by looking — you have to check the device's specifications.
- On Windows, open Settings → System → Display → Advanced display to see the active resolution, refresh rate, and which output is in use.
- On a Mac, hold Option and click the Apple menu → System Information → Graphics/Displays.
- USB-C is the exception to trust. A USB-C port only carries video if it supports DisplayPort Alt Mode or Thunderbolt — look for the DisplayPort or Thunderbolt logo beside it, and see USB-C as a display cable.
Once you know what the device outputs, the Max Resolution & Refresh Rate Finder shows what that port and cable combination can actually drive, and the Cable Selector Guide works out the cable or adapter for connecting it to your display.
Device ports: frequently asked questions
What HDMI version does the PS5 have?
The PlayStation 5 has a single HDMI 2.1 port. It can output 4K at 120 Hz and 8K at 60 Hz, and supports VRR and ALLM.
Reaching 4K at 120 Hz requires an Ultra High Speed HDMI cable — the one supplied in the box. An older High Speed cable will cap the console at a lower mode or drop the signal altogether, which is the most common cause of a PS5 refusing to offer 120 Hz.
Does the MacBook Air have an HDMI port?
No. No MacBook Air has an HDMI port. It drives external displays over its Thunderbolt / USB-C ports, so you need a USB-C to HDMI adapter or a USB-C to DisplayPort cable.
The 14-inch and 16-inch MacBook Pro do have a built-in HDMI port. How many external displays a Mac can drive depends on its chip tier rather than on the cable you use.
Do RTX 40 series cards have DisplayPort 2.1?
No. GeForce RTX 40 series cards use DisplayPort 1.4a, not 2.1 — a common point of confusion, since the same cards carry HDMI 2.1.
On that generation HDMI 2.1 is actually the higher-bandwidth output: about 42.67 Gbit/s usable, against 25.92 Gbit/s for DisplayPort 1.4a. Both reach 4K at 240 Hz with DSC. DisplayPort 2.1b at UHBR20 arrived with the RTX 50 series, and needs a DP80 certified cable to run at full rate.
How do I tell if my HDMI port is 2.0 or 2.1?
You cannot tell by looking. HDMI 2.0 and HDMI 2.1 use physically identical connectors, and the version is almost never printed on the device. Check the manufacturer's specifications for your exact model number.
As an indirect test, open your display settings and see whether 4K at 120 Hz is offered: that mode needs HDMI 2.1 at full color. Cables are the same story — there is no such thing as an “HDMI 2.1 cable,” only cable speed ratings.
Can a Nintendo Switch output video without the dock?
Not with a plain USB-C cable. Both the Switch and the Switch 2 send video to a TV through the dock, which is where the HDMI output lives.
Some third-party USB-C hubs do work, but many do not: the console is particular about the USB-C power delivery and video negotiation it expects, and a hub that gets it wrong produces a blank screen. The official dock is the reliable route.
