# 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](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. - [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. - [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 - [Connector Compatibility Matrix](https://www.dvihdmicables.com/Reference/Matrix): Which video connectors work together directly, with adapters, or require active converters. - [Connector Chart](https://www.dvihdmicables.com/Reference/Connectors): Visual identification chart for DVI-D, DVI-I, DVI-A, HDMI, SVGA, DisplayPort, and DFP connectors. - [Cable Assemblies Chart](https://www.dvihdmicables.com/Reference/Cables): All available cross-technology cable assemblies (DVI-to-HDMI, DisplayPort-to-HDMI, etc.). - [Adapter Assemblies Chart](https://www.dvihdmicables.com/Reference/Adapters): All available plug/receptacle adapter combinations. - [Reference Charts Index](https://www.dvihdmicables.com/Reference/Charts): Entry page linking to all reference charts. ## Guides - [Tools](https://www.dvihdmicables.com/Tools): Hub for the site's interactive tools — the Cable Selector Guide and the Video Bandwidth Calculator. - [Cable Selector Guide](https://www.dvihdmicables.com/Guide): Interactive picker — select a source connector and a display connector to get the recommended cable, adapter, or converter. - [Connector Identifier](https://www.dvihdmicables.com/connector-identifier): Interactive decision tree — answer questions about a connector's shape and pins (screws, latch, flat blade, reversible, size) to identify it (HDMI, DisplayPort, DVI-A/D/I, USB-C, VGA, Mini/Micro HDMI, Mini DisplayPort) with a picture and a link to learn more. - [Video Bandwidth Calculator](https://www.dvihdmicables.com/Technology/bandwidth-calculator): Interactive tool — enter resolution, refresh rate, color depth, and chroma to estimate the required video data rate and see which HDMI/DisplayPort versions and cables support it, with or without DSC. - [Frequently Asked Questions](https://www.dvihdmicables.com/FrequentlyAskedQuestions): Definitions for common video acronyms (TMDS, HDCP, CEC, EDID, etc.) and explanations of digital-vs-analog signaling, HDCP key revocation, and CEC features. - [Troubleshooting](https://www.dvihdmicables.com/Troubleshooting): Fixes for common video-cable problems - no signal, black screen after sleep, 4K/HDR not working, no audio over DVI-to-HDMI, flicker/dropouts on long cables, passive adapter showing nothing, and HDCP black-screen errors. - [Where to Buy](https://www.dvihdmicables.com/WhereToBuy): Recommended retailer for DVI, HDMI, SVGA, and DisplayPort cables, adapters, and converters. ## Site - [Sitemap (XML)](https://www.dvihdmicables.com/sitemap.xml): Machine-readable index of all canonical pages. - [Sitemap (HTML)](https://www.dvihdmicables.com/Sitemap): Human-readable site index. - [Privacy Policy](https://www.dvihdmicables.com/Privacy) - [Disclaimer & Trademarks](https://www.dvihdmicables.com/Disclaimer): Trademark attributions (HDMI, DisplayPort, Thunderbolt, USB-C, etc.), affiliate disclosure, and informational-use notice.
