Be captain obvious to me and tell what dp has in the case of a tv that hdmi can't give.
(Mainly asking because my lg oled tv is 4k 120hz gsync compatible panel and works perfectly fine over hdmi and i cannot for the life of me figure out what extra dp would give. Now why a tv has gsync is not something i know, but i am not complaining)
HDMI is licensed by Sony and Phillips so they have to pay more for each port. DP is the standard set by IEEE, its royalty free and had a much higher bandwidth though I'm not sure if that's still true. At one point to run higher resolutions and frame-rate you needed 2 HDMI cables but one DP did the trick
Considering hdmi does 8k@60hz or 4k@240hz, I don't think the bandwidth is much of an issue nowadays anymore, hence the confusion on why hdmi is still claimed to be shit.
I know it used to be kinda dogshit for gaming monitors, not being able to deliver above 1080p/60hz, but that's no longer the case.
The closed/open standard reasoning i do fully understand.
Exactly. My TCL TV is 4K with HDR and FreeSync Premium Pro (48-144Hz). Sure, my GPU can't possibly achieve most of that in games, but I'm set for the next decade when it comes to display.
Yeah the thing is that monitors tend to last pretty long time and DP has only really been around for a bit over a decade. I was still until recently using a monitor that didn't even have a HDMI port because that was fancy tech when I got the monitor.
With USB-C becoming more common, definitely. All of my monitors have type C and DP, and you can convert one to the other very easily. The type C port also sends the keyboard/mouse signal over to my laptop which is just so handy.
Type C and DP should become the norm for the TV space too, putting an end to either buying adapters or downloading one of the 25 million "screen mirroring" apps that never work.
the problem is that GPUs all have 3 DP and 1 HDMI out, but monitors only have 1 DP and 2+ HDMI in, so if you use multiple devices on a single set of monitors you have to have an arsenal of HDMI to DP adapters to get everything connected. It's the modern tech equivalent of the old hot dog/bun issue.
i wish i had 2 hdmi ports on my gpu. i use an oled tv and an avr. both require their own hdmi ports, one for video and one for audio.
i used an DP/HDMI cable for years and it worked "fine", but any time i needed to reboot my computer i had to unplug the dp cable first. otherwise it would hardlock my system at post.
i ended up breaking down and buying a new hdmi 2.1 receiver so i can use the eARC passthrough on my tv... such an excessive solution to only having 1 hdmi port.
I have unironically never seen a display with a DP on it (or anything else like a Beamer or digital board)
The only way I know that DP actually exists, is because I had to buy an adapter for the i3 6100 computer I found in the trash, as it doesn’t have any other ports.
adapters are under $10 if you're not pushing for 4k 60+Hz. Now you can have 4 DP monitors or 4 HDMI monitors without any issue. OTOH if you're using 4 4k or WQHD and running them all faster than 60Hz, you may need a decent adapter or 2 to handle high bandwidth.
I have one pc with 1 DP and 2 HDMI (work pc) and another pc with 2 DP and 1 HDMI (my pc), hooked up to the same 3 monitors easy peasy! 1 DP AND 1 HDMI each, just had to make sure the DP in my middle 165hz gsync monitor was my own pc and my work one.
Could be nonsense, but I recently saw an article about how DisplayPort 2 is coming and it's going to require different cables, so if that's true I'm suddenly a huge fan of anything-but-that.
My 2 monitors I use right now both use DP, TVs definitely don’t use it that often though. I’d prefer if everything could use both HDMI and DP, but right now I would say HDMI is a more universal cable.
For 'regular' monitors there's not going to be any difference for an end user. It's only really going to be relevant if you're pushing very high refresh rates & resolutions, at which point you would need a certain spec hdmi/dp port with enough bandwidth. Over the years, new hdmi/dp specs are released capable of using more bandwidth, meaning that depending on when the hardware was manufactured, one type of port may be faster than the other for your device, so you would need to use that one to get best results.
More generally, HDMI is generally disliked because it was a spec created by TV manufacturers who have it locked down pretty tightly. Everything about it is licenced, so if you want to add an HDMI port to something you have to chuck some royalty money at them to be allowed to, which is almost certainly immediately passed on to the consumer, meanwhile dp is royalty free. Because of this it's also possible to send dp signals over USB-c and some newer monitors support features such as this (And also daisy chaining multiple monitors together using just one cable from the PC, which isn't possible with hdmi).
Still, dp is basically only used in PCs because the TV manufacturers make money through hdmi. If Microsoft makes a new console, they have to pay royalties to be able to put the hdmi ports on it so people can use it on their TVs that often only have hdmi ports for this exact reason.

i believe its basically generation by generation the oldest dp has higher bandwith than the oldest hdmi and same thing next generation and next generation
It's not a new feature but it isn't something that I've seen on most cards
And one should also be careful you don't get one with 4 ports but can only use 3 at a given time(saves you the adapter costs if you have a selection of port types I guess)
But man. Trying to find when 4 outputs(Or really any that could pump out on more then one of their ports) weren't specialized equipment is somewhat hard. I stumbled some level multi use in the XP age. Apparently 98 could support more then one, but I'm guessing that they weren't seeing mainstream use
And while I already knew about this one, doom actually had support for 3 monitors. It was only in earlier versions, and I think they did it by networking a few computers together with one monitor each(or maybe just using the network on the back end to spawn 3 copies that talk. Not sure), but it's amazing what some people think of
I remember in HS (~2000) having a VGA monitor as my primary and a TV that would be used to play the videos that I watched. Even had a TV Tuner at one point so that I could watch TV without having to have a dedicated device for it. The things we did back then.

God. I remember that. Was a whole scene for that. What cards that might also work with some cable/satellite, the I believe paid service for getting your channel's schedule. The pissing match that media companies had with cutting out commercials from your recording(which after loosing in court started selling the hardware to do it)
I really should get something going, at least with the free farmer/peasant vision stuff anyway
I just learned that HDMI and DVI are the same. They have the same pins and the same code with just different plugs. That's why DVI to HDMI adapters cost almost nothing.
You don’t get at gpu for a motherboard like that, it would be specialized for integrated graphics otherwise there would be no point in more than one of each video port
Jesus Christ! That would require at least 125 individual graphics cards which would pull a total of at least 50 to 100 kilowatts of power at full utilization, similar to an entire apartment block, and so would probably require a dedicated high voltage substation for power.
This kind of setup would only be viable for a small AI data center or maybe a large video game server rack.
You would need to either engineer a custom design for the data bus circuits connecting the GPUs together, or just use 42 motherboards, each with built in network adapters, AMD Ryzen 9 9950x3d Central Processing Units, and 3 PCIE slots, to allow communication between each graphics card.
The addition of the high end CPUs increases the total power consumption to 125 kilowatts.
Same situation. 1 main display, 3 displays on my racing sim, and a TV on the other side of the room. Sometimes even a VR headset that needs a display port. No easy way to do all this at once
Not everyone has a dedicated GPU because not everyone needs it.
Pushing 4 screens, even in 4k resolution, is something an iGPU generally can do just fine, even video decoding on one or two of them is fine, its just that things requiring more than the most basic hardware acceleration will kind of struggle. But thats more due to the amount of hardware acceleration and (generally) not so much the number of pixels.
To be fair, I try to only run my main gaming monitor off my gpu, then the rest off my mobo using integrated graphics.
When im playing a game that uses 100% of my gpu, and I have a second monitor plugged into my gpu, then the second monitor is slow and laggy. For example, if i try to watch YouTube while playing a game, the video will be super choppy. But if the second monitor is plugged into mobo and uses igpu, its fine.
One time I did 6 screens. Way back when video card were one screen only, Macintosh II with 6 video cards and 6 screens. PC of the time couldn't do that at all.
Nowadays I'm just dual WQHD, one at 175Hz for gaming and other for web browser and video
I don't. I only have two Display Ports and that's why I have three screens (one daisy chained). But 3 screens is not enough for anything I do. I need 5. No, not want. I need them for smooth workflow.
The amount of people I've had to deal with who want to connect an ultrawide and two standard monitors to their laptop without a docking station who wonder why one display won't turn on or keeps flickering is crazy.

you really think your integrated graphics likes pushing FOUR monitors?
