Hi, there! I'm a veteran electrical engineer with a passion for A/V technology. I've been working with everything from CRT televisions to the latest 8K displays for over 20 years, and I'm happy to help clear up any confusion about Slimport and MHL.
## Slimport vs. MHL: A Detailed Look at Two Mobile Display Technologies
Slimport and MHL (Mobile High-Definition Link) are both technologies that allow smartphones and tablets to output audio and video to external displays, like TVs and monitors. While they share a common goal, they differ in their underlying technology, capabilities, and adoption rates. Understanding these differences is crucial when choosing compatible devices and cables.
1. Underlying Technology:
* MHL: MHL utilizes a technology called Transition Minimized Differential Signaling (TMDS), the same technology used in HDMI. It essentially adapts the HDMI signal for transmission over a smaller, five-pin connector.
* Slimport: Slimport, on the other hand, leverages the DisplayPort technology. DisplayPort is known for its high bandwidth and ability to drive multiple displays from a single output, making it suitable for desktop computers and professional displays. Slimport adapts this technology for mobile devices, utilizing the device's micro-USB port for signal transmission.
**2. Video Resolution and Audio Capabilities:**
* MHL: MHL supports a range of video resolutions, with early versions supporting up to 1080p and later versions supporting 4K resolution at 30fps. It also supports multi-channel audio, including Dolby Digital 5.1 and 7.1 surround sound.
* Slimport: Similar to MHL, Slimport also supports high video resolutions, including 4K resolution at 60fps. It, too, supports multi-channel audio, ensuring a high-quality audio-visual experience.
3. Power Delivery:
* MHL: One of the significant advantages of MHL is its ability to deliver power to the connected mobile device. This means you can charge your phone or tablet while it's connected to an MHL-enabled display, eliminating the need for an additional power source.
* Slimport: Slimport, in its standard form, does not provide power to the connected device. However, some manufacturers have implemented proprietary extensions that enable power delivery over Slimport, though this is not universally supported.
4. Connector Types and Cables:
* MHL: MHL typically uses a micro-USB connector on the mobile device side, requiring a passive adapter cable to convert the signal to HDMI for connecting to a display.
* Slimport: Similar to MHL, Slimport also utilizes the micro-USB port on the mobile device. However, it requires an active adapter cable to convert the DisplayPort signal to HDMI or VGA for compatibility with a wider range of displays.
**5. Device Compatibility and Adoption Rates:**
* MHL: MHL enjoyed wider adoption in its early days, finding its way into smartphones and tablets from major manufacturers like Samsung, Sony, and HTC. However, its popularity has waned in recent years, with fewer devices incorporating the technology.
* Slimport: Slimport has seen relatively limited adoption, primarily finding its way into LG and Google Nexus devices. Its reliance on active adapter cables and the emergence of wireless technologies like Miracast and Chromecast have contributed to its limited adoption.
Conclusion:
Both Slimport and MHL achieved their goal of enabling high-quality audio and video output from mobile devices. While MHL initially gained wider acceptance and offered the advantage of power delivery, Slimport boasted higher bandwidth and the flexibility of DisplayPort technology. However, with the rise of wireless technologies and the decreasing reliance on wired connections, both technologies have seen a decline in their adoption rates.
When choosing between the two, compatibility with your specific devices is paramount. Check the specifications of your smartphone, tablet, and display to determine which technology they support. If both options are available, consider your priorities regarding power delivery and the availability of adapter cables. Ultimately, the best choice depends on your individual needs and the capabilities of your devices.

Both essentially achieve the same thing, but there are some key differences. The key difference is that MHL outputs through the HDMI standard, whilst SlimPort uses the VESA standard meaning it can output to HDMI as well as VGA, DVI and DisplayPort.
