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?

I know that DisplayPort has advantages over HDMI but could not exactly remember, so I asked ChatGPT. Here is what it had to say:
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.

Sometimes I'm perusing development subreddits and I get a little depressed by what i find. As an example, recently someone asked if there was a library that could drive 8 stepper motors at a time. The answer is virtually any C++ library can if you create 8 instances, but they wanted something that would handle making all the motors operate in tandem somehow, and ummm no. you have to code it yourself. Cooperatively thread everything in a master loop, use a state machine. Back when I learned to code solving problems like this meant you were a coder. Now it seems like people just expect that there's a library that will solve whatever problem they're after solving. What are you even doing? Are you coding or are you just gluing things you don't understand together?
Edit: Guy responded to tell me I was incorrect. He's still looking for that magic library.
And then i log out of reddit for a week.
Am I just getting old and crotchety? Was it always like this and I just didn't notice? Has the Internet just made it more apparent?

No, it wasn't always like this. We used to take great pride in DIY stuff, even with code, to do things no one else is doing. I preferred projects that experts said couldn't be done, like the time HP told me that there's no way to connect HP computers from two different divisions together. That was fun, and yes, that was a long time ago.
But since Easter is coming soon, and you sound like you need another project that's more entertaining, here's one for you: Peeps[^]

You are fine. Internet does makes it more apparent.
Here is my take and nothing new. The proliferation of software (and hardware) products for internet, local net, gaming, business, streaming entertainment, etc. has made programming a super wide-spread requirement, faster the better both in execution and implementation. Disciplined programming, if any, is taught to some degree in computer courses, but executed more or less by dictates of management or senior programming staff. But I am old and crotchety as well, so I may be missing some things.

The internet makes lazy programmers expect others to do the work they are supposed to be doing.
As others have mentioned, refer to QA.

Have you wandered into the world of Python, proponents seem to have the same attitude. The really shocking thing was that corporate seemed to feel this was a legitimate way of creating a solution.

Use hardware logic to do serial to paralel conversion sending 8 identical (if desired) bit streams out to 8 steppers. Or just fake it all in Microcode.

I think they were trying to get them synchronized, but not necessarily copying each other.

For some reason today, I started wondering if anyone (companies specifically) was still using Unix -- any distro from the past which was still considered Unix & being used at a company.
I was assuming that Linux has killed Unix installations and forward development.
I found this: Unix is dead. Long live Unix! β’ The Register[^]
What is your experience with this? Any company you are working for that is using a Unix distro?
Just curious.
Oh, and I wrote this from my new Mac PowerBook M3 (36GB ram) and maybe macOS is considered Unix?
Not sure, but I'm reading this article now: https://www.howtogeek.com/441599/is-macos-unix-and-what-does-that-mean/[^]
EDIT 2
I thought maybe BSD was still around, but looks like it isn't: Berkeley Software Distribution - Wikipedia[^]
EDIT 3
Very interesting (from that 1st article above):
Quote: There are two standards that certify UNIX: POSIX and Single UNIX Specification (SUS). SUS is a superset of POSIX. So, something can be POSIX compliant, but that doesn't make it UNIX. However, if something is SUS-compliant, it's a UNIX.

The only area where I used UNIX was at Uni, everywhere else it been Windows or Linux... Too big, too costly, neat Keyboard with the short cuts as Keys.

Yeah that makes sense, since I know it was originally created for "big metal" like the PDP-11 etc.
Thanks for sharing.

Also an oddity between Windows and UNIX is the memory in Intel is 64K chunks, UNIX is flat no divisions & so is Linux which confused the out of me trying to read a value to see if a card was present, not to sure about the PDP series might have had flat memory and does the Mac, I'm guessing the Apple][ had 64K chunks as that was a common value for memory (Commodre 64 etc)

Wikipedia says that HP-UX had a release last May and that IBM-AIX had a release in November, so there must still be some people using Unix, somewhere. As for PC level OS, Linux has pretty much sucked up all the oxygen, but Open/Free/Net BSD are still out there and have a following. SCO is still available too, it seems, but since the Linux copyright debacle, I don't think it's too popular. I don't even know who owns it, anymore.
Side note: My first professional job was working with MS Xenix on a Tandy 6000 (8MHz M68K, 1MB Ram, 15MB HD). Today, it's hard to imagine that you could do anything useful with those specs. That it could be used in a multi-user environment (some of our clients had 4 or more serial terminals) is just mind-blowing. Today, I wonder if you could get a stripped down linux kernel to fit, never mind getting 2 or 3 user shells up and running.
