The vast majority of the TVs only come with HDMI .. not even good enough analog inputs anymore..

I 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.

Which 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).

I'm pretty sure TVs go higher in price than monitors - although professional monitors do put up a fight.

This 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.

I want a TV with DP. Do you have a recommended source for where to pick up commercial TVs?

I live in Germany and I got mine from https://www.visunext.de/

What really drives me nuts is smart TVs with 100mbps Ethernet connections. When I bought a tv we looked in vain for gigabit Ethernet.

It 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.

>DIY x86 HTPC

ARM slander was not warranted

Are there DIY Arm boards that make a good HTPC? Do they have hardware video decoding?

TVs 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.

Unfortunately we're the weird ones for wanting to stream >100mbps content.

My 2020 LG CX has a USB 2.0 port and I get ~300mbps with a gigabit adapter, if the TV you ended up with has a USB port it's worth a try.

What >100mbps content is there? 4K bluray just needs a bigger buffer to handle >100mbps spikes (Kodi for example offers this) and Moonlight/Apollo/etc is well into diminishing returns

4k blu-ray remuxes regularly break 100mbps for long enough to cause problems on my TV, unless I use either wifi or the USB adapter. Others have done investigations showing in some movies the bitrate will exceed 100mbps for minutes at a time.

With what feels like weekly posts about someone being shocked their smart TV is showing them ads, I'm surprised you looked for gigabit for your TV.

I've had a smart TV for over 5 years and never connected it to the Internet.

I connected my Samsung TV to the WiFi for the first time two weeks ago because I wanted to play with the multi-screen-view thing, and it didn't appear to work with two HDMI cables.

It has not shut up asking me to update the fucking thing. Every time I turn the TV on, about twenty seconds later an update prompt will pop up, and it will not go away until I actively dismiss it. This happened even after disconnecting and forgetting the wifi. Never again.

Unless 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

AMD Radeon 7000 and 9000 series all support DisplayPort 2.1

6000 however does not but supports HDMI 2.1 (no yet on Linux).

Not to mention TVs have been pretty much always been HDMI-only and they are the only realistic option for a living room sized monitor.

Some 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.

My 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.

For one, DisplayPort doesn’t support HDR output

The 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.

For 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.

> 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.

That 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.

Do you mean in practice, or something? DP definitely supports HDR, and it seems to work fine for me.

If true, not supporting HDR is a feature

displayport has supported HDR10 since 2016

and displayport 2.0, since 2019, has supported all the same variations (hdr10+, dolby vision) that HDMI does

This seems wrong to me? I use it to do so every day.

Confidently incorrect.

My main monitor is 4K 240 hz HDR and it works great on my DisplayPort cable, especially the HDR.
