Because the standard has evolved over the years, not all DisplayPort cables will work properly at the latest speeds. The original Display 1.0-1.1a spec allowed for RBR (reduced bit rate) and HBR (high bit rate) cables, capable of 5.18 Gbps and 8.64 Gbps of data bandwidth, respectively. DisplayPort 1.2 introduced HBR2, doubled the maximum data bit rate to 17.28 Gbps and is compatible with standard HBR DisplayPort cables. HBR3 with DisplayPort 1.3-1.4a increased things again to 25.92 Gbps, and added the requirement of DP8K DisplayPort certified cables. Both HDMI and DisplayPort can also carry audio data, which requires bandwidth as well, though it's a minuscule amount compared to the video data. DisplayPort and HDMI currently use a maximum of 36.86 Mbps for audio, or 0.037 Gbps if we keep things in the same units as video. Earlier versions of each standard can use even less data for audio. One important note is that HDMI supports audio pass through, while DisplayPort does not. If you're planning to hook up your GPU to an amplifier, HDMI provides a better solution.
DisplayPort looks similar to HDMI but is a connector more common on PCs than TVs. It still allows for high-definition video and (in many cases) audio, but its standards are a bit different. On modern monitors, you'll likely find any of the following: I have not compared switch latency to Display Port, so would be curious if anyone here has impressions Before choosing the cable, you will need to consider the connector type on each end of the cable and also the cable length. Types of DisplayPort
Other use cases might push you toward DisplayPort as well, like if you want to use MST to have multiple displays daisy chained from a single port. That's not a very common scenario, but DisplayPort does make it possible. Home theater use on the other hand continues to prefer HDMI, and the auxiliary channel can improve universal remote compatibility. If you're hooking up your PC to a TV, HDMI is usually required, as there aren't many TVs that have a DisplayPort input. For Nvidia gamers, your best option right now is a DisplayPort 1.4 connection to a G-Sync certified (compatible or official) display. Alternatively, HDMI 2.1 with a newer display works as well. Both the RTX 30-series and 40-series cards support the same connection standards, for better or worse. Most graphics cards will come with three DisplayPort connections and a single HDMI output, though you can find models with two HDMI and two (or three) DisplayPort connections as well — only four active outputs at a time are supported.
HDMI is an abbreviation of ‘High Definition Multimedia Interface’, and it refers to an interface that is used for transferring HD data from one device and transferring it over to another. These are somewhat simplified explanations of each HDMI version, as there are other feature improvements in each standard, but they're the things most PC users will care about. If you want to take full advantage of those specifications, you'll also need an HDMI cable capable of the correct bandwidth. AVACON is one of the affordable DisplayPort to HDMI cables to connect your laptop to a TV. If you have a full-HD display or TV, go with this one. AVACON’s DisplayPort to HDMI cable is ideal for starters looking to mirror their laptop or PC screen to a TV. It can transmit HD audio and video to the connected device. We advise avoiding this if you have one of the modern 4K projectors or TV to connect.

The VESA governing body defines the standards, and there's even a handy spreadsheet that spits out the actual timings for a given resolution. A 1920x1080 monitor at a 60 Hz refresh rate, for example, uses 2,000 pixels per horizontal line and 1,111 lines once all the timing stuff is added. That's because display blanking intervals need to be factored in. (These blanking intervals are partly a holdover from the analog CRT screen days, but the standards still include it even with digital displays.) Thankfully, most DisplayPort problems are relatively easy to avoid or fix. Here are four common DisplayPort problems, along with advice for diagnosing and solving them. Display Adapter Link Failure In addition, DisplayPort has a few other useful features. First, it supports AMD's FreeSync and Nvidia's G-Sync, so you can have a tear-free gaming experience no matter which brand of card you use (as long as your monitor supports the technology, of course). The Radeon software should alert you to the problem with an error message, but this is easy to miss when it pops up. Open the Radeon software and have a look at the notifications. The message will be: This is how (mainly) TVs are able to access HD sound and visuals and is done through the use of just one simple HDMI cable. What Is DisplayPort?
The cable above isn’t ideal for 2K or 4K displays. After all, you shouldn’t settle for a lower resolution output if your TV supports 4K streaming. If you are among them, get Warrky DisplayPort to HDMI cable. HDMI does not natively support MST. However, you can use a DisplayPort hub with an HDMI adapter to daisy-chain multiple HDMI monitors through the DisplayPort on your computer. The latest display connectivity standards are DisplayPort and HDMI ( High-Definition Multimedia Interface). DisplayPort first appeared in 2006, while HDMI came out in 2002. Both are digital standards, meaning all the data about the pixels on your screen is represented as 0s and 1s as it zips across your cable, and it's up to the display to convert that digital information into an image on your screen.
What Is DisplayPort?
And there’s the final rub: Which port you choose depends on the capabilities of both your monitor and your video card. If you’re looking to use the features of HDMI 2.1, for example, you need a monitor with an HDMI 2.1 port and a video card with an HDMI 2.1 port—if one of them is running HDMI 2.0, you won’t be able to take advantage of those newer features. I know that HDMI can be very slow (depending on monitor)... sometimes as much as 5 seconds to see the new source. I assumed that was content protection built into the standard and/or slow decoder ASIC.
You might think it's a simple matter of hooking up whatever cable comes with your monitor to your PC and calling it a day, but there are differences that can often mean a loss of refresh rate, color quality, or both if you're not careful. Here's what you need to know about DisplayPort vs. HDMI connections.Displayport cables are high performance digital cables used to connect computer monitors, laptops, and other devices to display screens. It supports the transmission of high-resolution video and audio signals, making it a popular choice for connecting devices that require high-quality display output. A display port is always male on the cable and female on the device. All DP cables have the same basic layout and wiring and will support any feature including audio, daisy-chaining, HDR and DSC.
