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.
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.
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.
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.
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 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.
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
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.
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.
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.
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.
