AMD. The final holdout, HDMI 2.1 support being blocked by the HDMI group, has been overcome w/ the HDMI group relenting and support is now landing in the kernel (expected in 7.2).

- cute_boi 5mo agoany reason why we are using hdmi over display port?
- saidinesh5 5mo agoThe vast majority of the TVs only come with HDMI .. not even good enough analog inputs anymore..
- 0cf8612b2e1e 5mo agoI have been told (but not confirmed) that is mandated by the HDMI mob. If you want HDMI on your TV, it cannot also have DP.
- okanat 5mo agoThis can only be true for consumer-grade stuff. Even then I just guess the manufacturers kind of cheap out. I have a dumb-ish Samsung Hotel TV / commercial TV at home. It has DP.
- MarsIronPI 5mo agoI want a TV with DP. Do you have a recommended source for where to pick up commercial TVs?
- okanat 5mo agoI live in Germany and I got mine from https://www.visunext.de/ https://www.visunext.de/
- bee_rider 5mo agoWhich is kind of funny. At least, to my mind this has associated HDMI-only with the budget option (TVs), and DP with the premium tier (monitors).
- account42 5mo agoI'm pretty sure TVs go higher in price than monitors - although professional monitors do put up a fight.
- bayesnet 5mo agoWhat really drives me nuts is smart TVs with 100mbps Ethernet connections. When I bought a tv we looked in vain for gigabit Ethernet.
- navigate8310 5mo agoIt is futile to expect the TV to be smart and support all sorts of apps and hardware only to be abandoned by the manufacturer years down the line. The only correct way to buy a TV imho is to hunt for a dumb but excellent display properties and get a streaming device such as Google TV Streamer, Apple TV or DIY x86 HTPC.
- cwel 5mo ago>DIY x86 HTPC ARM slander was not warranted
- Dylan16807 5mo agoAre there DIY Arm boards that make a good HTPC? Do they have hardware video decoding?
- ihsw 5mo agoYour best bet is going to be Raspberry Pi devices: https://github.com/blakeblackshear/frigate/discussions/18431 https://github.com/blakeblackshear/frigate/discussions/18431 You can try Googling around for bespoke products but they will almost exclusively come from China and they will be very overpriced due to the soldered RAM.
- izacus 5mo agoTVs are made with BOM of like 10$ for the SoC, so it's the cheapest crap available. Then again - none of the streaming services are streaming at anything remotely close to 100Mbps so I doubt they consider it necessary to upgrade to GbE.

- bisby 5mo agoSome people have TVs or displays that only use HDMI. I personally wouldn't recommend HDMI if DisplayPort is available, but if HDMI is your only option, then having it work properly will be important.
- jaxefayo 5mo agoFor one, DisplayPort doesn’t support HDR output
- Gracana 5mo agoDo you mean in practice, or something? DP definitely supports HDR, and it seems to work fine for me.
- hmry 5mo agoThat can't be right. I'm reading this comment on an HDR monitor over DP right now. Don't all USB-C video outputs use DP alt mode too, with an HDMI adapter at the end? And they can do HDR.

- funimpoded 5mo agoThe cable length limitations are also a pain in the ass for not-uncommon A/V system configurations. 6' recommended max, and the best you might get working stably if the device and cable gods smile on you is 15'. 6' is the lower edge of acceptable for just about any A/V system setup (in practice it means your devices need to be within about a meter of the screen's port[s], which is pretty close) and even 15' is still too short to be useful for, say, a projector, or a "the A/V receiver or HDMI switch is over in that cabinet, the TV is on this wall across the room" situation. HDMI goes 25'+, no problem.
- Dylan16807 5mo agoFor 4k at 60Hz, you'd need HDMI 2.0 or DP 1.2. At those speeds, both kinds of cable should be able to reach 25 feet, and I can find reputable brands selling both kinds at the length.
- simoncion 5mo ago> HDMI goes 25'+, no problem. Yep. That's likely because that's an active cable. Active DisplayPort cables exist, too. Here is one vendor selling active UHBR10 cables [0]. If you don't NEED UHBR, then you'll find your selection to be much, much larger. I've been using some Monoprice-branded 50 and 100 ft active fiber-optic HBR3 DisplayPort cables for years with no problem.

- eikenberry 5mo agoMy monitor has 1 displayport and 2 hdmi and I have 2 computers I use with it. They can't share the displayport. All comparable monitors (last time I checked) have the same. So it'd be nice if both worked.
- ThatPlayer 5mo agoUnless you're on the absolute newest stuff with DisplayPort 2.1, HDMI 2.1 has more bandwidth than DP1.4. That'll be Nvidias 2000 through 4000 series. No DisplayPort 2.1 until the RTX 5000s. And then monitors released during this time generally do the same too. Also if you want to use it through a capture card, HDMI ones are way more common and cheaper
- esseph 5mo agoAMD Radeon 7000 and 9000 series all support DisplayPort 2.1
- account42 5mo ago6000 however does not but supports HDMI 2.1 (no yet on Linux).
- account42 5mo agoNot to mention TVs have been pretty much always been HDMI-only and they are the only realistic option for a living room sized monitor.
- somat 5mo agoI sort of figured that HDMI stupidity was strategically a good thing as it sort of brought the dynamic of the HDMI consortium and VESA. specifically how they treat the end users, more to the public eye. That is, more people being subtly pushed to using display port is not a bad thing.
- _puk 5mo agoI was faintly surprised that my recent monitor purchase came with a displayport cable. Didn't help connecting it to my Macbook, but still..
- esseph 5mo agoDisplayPort has been running the best PC high end monitors for a long while. HDMI OTOH has been in A/V land (DRM management).
- babypuncher 5mo agoDon't most monitors ship with DisplayPort cables? All of mine have. HDMI is more popular with TVs/home theater systems.
- tombert 5mo agoOutside of the ones built into laptops, all my "monitors" for the last decade have been TVs, just because they tend to be cheaper at a "price to size" level. None of them ever seem to have DisplayPort.
- babypuncher 5mo agoYeah TVs typically don't have DP, because extra HDMI ports are usually more valuable in a home theater setting. Game consoles, receivers, video players all have HDMI and don't have DisplayPort, meanwhile every graphics card and laptop usually supports both, so having an extra HDMI port ends up being more versatile.
- somat 5mo ago
- perching_aix 5mo agoI didn't follow this story much: how exactly did they get past the legal hurdles? Or there never actually were any hurdles, just sabre rattling?
- JCTheDenthog 5mo agoPurely rumor, but supposedly Valve put tons of pressure on them (no idea by what means, again this is all rumor) because they wanted support for the Steam Machine release.
- account42 5mo agoHoping they'll also add VRR - that's the one thing that isn't currently working with my DP->HDMI adapter setup, 4K@120Hz already works fine.
