# DVI HDMI Cables > DVIHDMICables.com is an informational resource about DVI, HDMI, SVGA, and DisplayPort video cables, connectors, and adapters. It helps readers identify the right cable or adapter for connecting a given source device to a given display, and explains the underlying technologies (TMDS, HDCP, CEC, ARC/eARC, VRR, HDR, etc.). ## Technologies - [HDMI Cable Technology](https://www.dvihdmicables.com/Technology/Hdmi): Overview of HDMI versions (1.3, 1.4, 2.0, 2.1, 2.1b), connector types (A, B, C/Mini, D/Micro, E), and key features (CEC, ARC, eARC, VRR, ALLM, HDR). - [DVI-A Cable (Analog Video)](https://www.dvihdmicables.com/Technology/dvi-a-hdmi): DVI-A carries analog video signals and is electrically compatible with VGA/SVGA. - [DVI-D Cable (Digital Video)](https://www.dvihdmicables.com/Technology/dvi-d-hdmi): DVI-D carries digital video only. Single-link vs. dual-link pin configurations and HDMI compatibility. - [DVI-I Cable (Integrated Analog & Digital Video)](https://www.dvihdmicables.com/Technology/dvi-i-hdmi): DVI-I carries both analog and digital signals through a single connector. - [DisplayPort Technology](https://www.dvihdmicables.com/Technology/DisplayPort): VESA-developed digital A/V standard, daisy-chaining, and DisplayPort-to-HDMI/DVI adapters. - [SVGA / VGA Technology](https://www.dvihdmicables.com/Technology/Svga): Analog video over the HD15 connector, including the distinction between VGA and SVGA. - [USB-C as a Display Cable](https://www.dvihdmicables.com/Technology/usb-c): How USB-C carries video via DisplayPort Alt Mode, Thunderbolt 3/4, and USB4. USB-C is a connector, not a video standard; video works only with DP Alt Mode/Thunderbolt. Covers max resolutions, power-plus-video on one cable, and USB-C to HDMI/DisplayPort/VGA adapters. - [HDMI Cable Types](https://www.dvihdmicables.com/Technology/hdmi-cable-types): HDMI cables are rated by bandwidth category (Standard, High Speed, Premium High Speed 18 Gbps, Ultra High Speed 48 Gbps), not by version. Which cable for 1080p, 4K60 HDR, 4K120, and 8K; why an "HDMI 2.1 cable" is a misnomer; and why a pricier cable does not improve a digital picture. - [DisplayPort Cable Types](https://www.dvihdmicables.com/Technology/displayport-cable-types): DisplayPort cables are rated by bandwidth (VESA certifications DP8K/HBR3 32.4 Gbps, DP40/UHBR10, DP80/UHBR20 80 Gbps), not by version. Which cable for 4K144, 8K, and DisplayPort 2.1; HBR/HBR2/HBR3/UHBR link rates; Mini DisplayPort. - [Video Cable Length Limits & Signal Reach Advisor](https://www.dvihdmicables.com/Technology/cable-length): Practical length limits for HDMI, DisplayPort, DVI, VGA, and USB-C; why high-resolution signals fade over distance; and passive vs active vs active-optical (AOC) cables and extenders. Includes an interactive advisor: give the connection, the mode you are running, and the distance, and it names the cable type that covers the run. - [Active vs Passive Adapters](https://www.dvihdmicables.com/Technology/active-vs-passive-adapters): Passive adapters re-route a compatible signal (e.g. digital DVI-to-HDMI, DP++ to HDMI); active adapters convert incompatible signals (analog<->digital, HDMI-to-DisplayPort). Which to use for each pairing and why a passive adapter may not work. - [HDR Explained](https://www.dvihdmicables.com/Technology/hdr): HDR10, HDR10+, Dolby Vision, and HLG compared (metadata, bit depth, use), plus the HDMI/DisplayPort versions and cable bandwidth needed for HDR. There is no special "HDR cable." - [Variable Refresh Rate (VRR)](https://www.dvihdmicables.com/Technology/vrr): VRR/Adaptive-Sync explained - FreeSync, G-Sync, VESA Adaptive-Sync, and HDMI Forum VRR (HDMI 2.1) compared, with the interface versions and cables needed for tear-free gaming. - [Display Stream Compression (DSC)](https://www.dvihdmicables.com/Technology/dsc): VESA's visually-lossless (~3:1) compression used by DisplayPort 1.4+ and HDMI 2.1 to reach 4K120 and 8K. It is device-side and automatic; there is no separate DSC cable. - [Chroma Subsampling](https://www.dvihdmicables.com/Technology/chroma-subsampling): 4:4:4 vs 4:2:2 vs 4:2:0 - full vs reduced color detail to save bandwidth. Use 4:4:4 for PC text, 4:2:0 for video; 4:2:0 is why colored text can look fuzzy. - [Cable Label Decoder](https://www.dvihdmicables.com/Technology/cable-labels): What the markings on a video cable actually guarantee, each classified as a real certification, a genuine spec, a marketing term, or a claim that tells you nothing. Covers Standard/High Speed/Premium High Speed/Ultra High Speed HDMI, VESA DP8K/DP40/DP80, Thunderbolt and DisplayPort Alt Mode on USB-C, DVI single vs dual link, and AWG/active/AOC. Key points: there is no such thing as an "HDMI 2.1 cable" (versions describe devices, cables carry speed ratings); a 240W USB-C charging cable can be USB 2.0 and carry no video; gold plating affects durability, not picture quality. - [EDID Explained](https://www.dvihdmicables.com/Technology/edid): Extended Display Identification Data - how a display tells the source its supported resolutions/formats. Why it causes no-signal and wrong-resolution issues, and what an EDID emulator does. ## Comparisons - [Comparisons Index](https://www.dvihdmicables.com/Technology/comparisons): Hub page linking the side-by-side connector comparisons below. - [DVI vs HDMI](https://www.dvihdmicables.com/Technology/dvi-vs-hdmi): How DVI and HDMI differ on signal type, audio, resolution/bandwidth, connectors, and cable length. Both use TMDS, so digital DVI and HDMI are compatible with a passive adapter (video only); DVI carries no audio. - [HDMI vs DisplayPort](https://www.dvihdmicables.com/Technology/hdmi-vs-displayport): How HDMI and DisplayPort differ on bandwidth, resolution/refresh rate, audio, multi-monitor daisy-chaining (MST), ARC/eARC, CEC, and USB-C. HDMI suits TVs/home theater; DisplayPort suits PC monitors. DisplayPort-to-HDMI works with a passive adapter (DP++); HDMI-to-DisplayPort needs an active adapter. - [DVI-D vs DVI-I](https://www.dvihdmicables.com/Technology/dvi-d-vs-dvi-i): DVI-D is digital-only; DVI-I is integrated digital+analog with four extra analog pins. A DVI-D plug fits a DVI-I socket but not vice-versa; only DVI-I can fall back to VGA via a passive adapter. - [DisplayPort vs USB-C](https://www.dvihdmicables.com/Technology/displayport-vs-usb-c): DisplayPort is a video protocol; USB-C is a connector that carries DisplayPort via DisplayPort Alt Mode. USB-C also carries USB data and power. When to use each. - [HDMI 2.0 vs 2.1](https://www.dvihdmicables.com/Technology/hdmi-2-0-vs-2-1): HDMI 2.1 (48 Gbps) vs HDMI 2.0 (18 Gbps) - 4K120, 8K, VRR, ALLM, eARC, Dynamic HDR. When you need 2.1 (4K120 gaming, 8K, lossless eARC) vs when 2.0 is enough, and which cable. HDMI 2.1 features are optional, so check the specific capability. ## How-To Guides - [How to Connect a Laptop to a Monitor or TV](https://www.dvihdmicables.com/how-to/connect-laptop-to-monitor): Step-by-step over HDMI, USB-C, DisplayPort, or VGA - identifying ports, choosing the cable/adapter, and configuring the display. - [How to Set Up Dual Monitors](https://www.dvihdmicables.com/how-to/dual-monitors): Step-by-step using separate ports, a DisplayPort MST daisy-chain, or a USB-C/Thunderbolt dock, then arranging the displays. - [How to Connect a PC to a TV](https://www.dvihdmicables.com/how-to/connect-pc-to-tv): Step-by-step over HDMI (or DisplayPort with an adapter), choosing a 4K cable, getting audio through the TV, and fixing overscan. ## Reference - [Device Port Lookup](https://www.dvihdmicables.com/Reference/device-ports): Which video ports common devices have, their maximum resolution and refresh rate, and the cable grade each needs - game consoles (PS5/PS5 Pro, Xbox Series X|S, Nintendo Switch and Switch 2, Steam Deck), streaming boxes (Apple TV 4K, NVIDIA Shield, Chromecast, Roku), Apple Macs (MacBook Pro, MacBook Air, Mac mini, iMac), and graphics cards (GeForce RTX 30/40/50, Radeon RX 7000/9000, Intel Arc).
