I've just been reading a bit about the differences, and see some mentions of Display Port being more capable in multi-monitor applications. My last PC build included a video card (ASUS TUF RTX 3060Ti) includes both types of connector, as do my two monitors, but I assembled it all using HDMI simply because that was the type of cable I had on hand. I know that a lot of you use two or more monitors; which do you prefer? If I switch to Display Port will I see enough improvement, if any, to justify the fairly cheap cost of new cables?

Quote: DisplayPort and HDMI are both widely used standards for connecting displays to computers, gaming consoles, and other devices. Each has its own advantages, and the choice between them depends on factors like your specific needs and the devices you're connecting. Here are some benefits of DisplayPort over HDMI:
1. Higher Bandwidth: DisplayPort typically offers higher bandwidth compared to HDMI. This means it can support higher resolutions, refresh rates, and color depths. For example, DisplayPort 1.4 supports 8K resolution at 60Hz, while HDMI 2.1 supports 8K at 30Hz.
2. Adaptability: DisplayPort is more adaptable to different types of displays and technologies. For instance, it can easily adapt to older VGA, DVI, and HDMI displays using simple passive adapters, while HDMI may require more complex converters for compatibility.
3. Multiple Display Support: DisplayPort supports daisy-chaining, allowing you to connect multiple monitors to a single DisplayPort output. This simplifies cable management, especially in multi-monitor setups, as it reduces the number of cables required to connect each display to the computer.
4. Longer Cable Lengths: DisplayPort cables can generally maintain signal integrity over longer distances compared to HDMI cables, especially at higher resolutions and refresh rates. This makes DisplayPort more suitable for setups where displays are located farther away from the source device.
5. Variable Refresh Rate (VRR) Support: DisplayPort has supported adaptive sync technologies like AMD FreeSync and NVIDIA G-Sync for longer than HDMI. This allows for smoother gaming experiences by synchronizing the refresh rate of the display with the output of the graphics card, reducing screen tearing and stuttering.
6. Audio and Video Separation: DisplayPort separates audio and video signals, which can be advantageous in professional setups where audio is handled separately from video. This allows for more flexibility in routing audio signals.
7. Future-Proofing: DisplayPort tends to adopt new technologies and standards earlier than HDMI. For example, DisplayPort 1.3 and 1.4 introduced support for higher resolutions and refresh rates before similar capabilities were available in HDMI.
Despite these advantages, HDMI remains popular due to its widespread adoption, compatibility with consumer electronics, and support for features like Consumer Electronics Control (CEC) and Audio Return Channel (ARC). Ultimately, the choice between DisplayPort and HDMI depends on your specific requirements, the devices you're connecting, and compatibility considerations.
If your monitor(s) support VRR then maybe it is worth your while. With HDMI, there are various grades and standards of cable, so not all HDMI cables are equal. If you are using HDMI, then make sure that you are using the correct standard required by your monitor(s) to get the best results.

Thank you, Graeme, that's really excellent information, and I appreciate you contributing it. I'm especially interested to learn that Display Port can be adapted to connect to a VGA monitor, as I fear that my friend who is getting a new Dell PC might have an older VGA monitor. I already know that the new PC is going to way outperform the video she has, but I'm having trouble getting her to let me get her a new display.

I used to work for a company that designed graphics adaptors, I thought DVI was the HP Digital Graphics standard they developed with some others, that became HDMI once the bundling of Audio signals were completed with the timing, to avoid the issues that plagued early DVD players with some units played the Audio out of time (a good drinking game in my student days!). I am pretty sure there won't be a visible difference, also I think there is at times too much emphasis put on cable quality. Like the HiFi speaker cables, you think there is a difference, that is all.

I just purchased a new ASUS PA279CRV monitor
I do not have a second monitor to test this
the manual says you can daisy chain to another monitor
and do picture in picture on one screen
It dose not support Windows 7 but I am using the drivers from my ASUS PA249
My graphics card forces me to use HDMI
price $414.00 free shipping from ASUS

My graphics card has both types of interface, and do my monitors. I'm just curious about whether there is any benefit to switching from HDMI to Display Port.

We still have a hardware section? Who knew? 
Yeah, the Lounge has indeed lost much of its former charm. Chatting with Nish in Trivandrum all night via his 1 kbps dialup connection stands tall in my fond memories! And we used to share all sorts of useful information around the world among the regular members. It's nice to see some of them still around, though, which makes it worth the time to stop by once in a while!

I did a comparison or may have seen this statement in a ASUS pdf about the
ASUS PA279CRV "the HDMI connection provides higher graphic display than Display Port"
I might have posted something in the Hardware Section with a question

Thanks for that tidbit! I may just have to try it, since cables are so cheap.
