Why don't any TVs have either DL-DVI or DisplayPort?

As above?

I mean they go through the effort of sticking a VGA port and PC audio (3.5mm) jacks on pretty much all TVs so it's not like they can't be bothered or they are not interested in the market. It's 2013, who the hell still uses VGA?

So since its not neglecting the market as they do stick on VGA inputs, then surely it's then something technical? Compatibility? Different technology?

What is it?

Annoying as bandwidth starved by hdmi, can't do 1080p 3D a above 30hz etc etc
 
most likely the costs involved.

i have just purchased a top of the range panel and this is my inputs/outputs. also in the most cases they probably do not see it as being needed.

people have hdmi as an alternative, if you are so obsessed with higher bandwidth then you need to look at a monitor really.

i imagine professional displays (the ones that cost £5K+, do have the input you are looking for as they are used in offices, etc.)

Input/Output

CI (Common Interface) yes
HDMI Input
HDMI Input 4 (4 side)
Support Feature Audio Return Channel (Input 2)
SD Card yes (SDXC)
USB2.0 3
Composite Video Input shared with Component AV2: CVBS w/Cable adaptor (lower)
Audio Input (for HDMI, Composite, Component) RCA phono type w/Cable adaptor x 1 (lower)
Bluetooth yes (Keyboards/audio devices)
Component Video Input shared with Composite RCA phono type w/Cable adaptor x 1 (lower)
LAN Port 1 (lower)
Digital Audio Output (Optical) 1 (lower)
Headphone Jack 1 (side)
21-Pin Input/Output AV1: AV In/Out, RGB In, Q-Link w/Cable adaptor (lower)
 
doubt it's cost, somehow. Displayport was designed from the ground up to be cheaper to manufacture and cheaper to licence. I say cheaper to licence, but it's actually royalty and licence-free so it's much cheaper.

No, it's probably down to prior agreements with HDMI Founders, over anything else. That or manufactures are just sticking with what works.

I think its probably more a case of virtually everything uses HDMI these days so its just not worth adding anything else.

Most basic computing devices also tend to use VGA, so through just the 2 they cover pretty much 99.999% of applications.

Plus dvi and hdmi can be easily interconnected with an adapter

If its worth adding a dead VGA port surely you would replace it with its replacement?

I haven't seen a VGA port on anything computing wise in the last 3 years, considering the manufacturers also make monitors that don't have VGA inputs why stick them on your tvs.

VGA is still used massively in certain computing sectors. Prime example being servers where every new Dell, HP etc all use VGA for local monitors output.

Different sectors though. Those sort of computers or servers will likely not ever need to be connected to a modern TV.

This. Most of the 4k/8k panels at trade shows were using HDBaseT to actually display content, which is very cheap for consumers and easily available. But you can't gold plate and braid an ethernet cable for £100, so they revert to HDMI v2 for consumer displays. Capitalism unfortunately!
 
its also down to copy write protection, dvi-I and hdmi both have hdcp, so you can play blurays via your pc to your tv. now theres a new standard of hdmi in the works so i guess that will work for 4k.

im not 100% sure whats happening as it seems to change month to month.
 
true, probably just hollywood wanting to make use a new standard to be able to try and control things, after all when hdmi a lot of people where still only using display port, so you couldnt start hooking up your pc to the tv.

im sure it will sort itself out by next year, after all not like any of us will be dropping £20k on a new screen now, even if we had the money when they will be a fraction of the cost next year.

Denon did try : http://usa.denon.com/us/Product/Pag...?CatId=Accessories(DenonNA)&Pid=AKDL1(DenonNA)

:eek:

My current TV doesn't have a VGA port, they just added another HDMI port. No major biggie tho as mini-DP to HDMI adaptors are cheap enough.
 
I assume that's the £800 Denon Cat5e cable? Link doesn't work. Anyway the point is the eletronics at either end, HDBaseT uses bog standard Cat5e as the transport and it has trickled into some projectors now (typically need long cable runs so it makes sense). It won't find it's way into normal price stuff for ages because they need the profit margin of accessories to actually make any money. Shame really! Just like DisplayPort 2.0, it's better than HDMI in pretty much every conceivable way.
 
For example i was looking at buying that 50" Sekei 4K TV which is ridiculously cheap but only comes with HDMI 1.4. Considering the interest the commuting world has given this TV, they’ve done themselves no favours. If they had included a DL-DVI or DP and what it seems no extra cost, I’m sure many would be all over it. The HDMI port included can barely run the TV so I’m staggered they didn’t include something with more bandwidth.
 
To be fair, most 4k content viewing will be movies which are 24p so it's not that bad :p. Of course the problem is they've managed to release the panel before the content, so the only thing you can really do is play PC games on it which mostly warrant <30fps!

Kind of the point, the only place you can get content from is the PC, and they havent included a port that can handle that content fully via the PC!!

30FPS is pretty much unplayable.
 
devices with vga ports very often have NO OTHER WAY to connect the video out to a display.

Also the 'vga port' is very often a component video port as well as a vga port, just happens to be in an hd15 connector.

HDMI and DVI can be adapted, but you can't adapt a VGA to a DVI for example.

I for one welcome our mulitple input port overlords. Nothing more frustrating than not being able to plug a device in because there's not a port available or suitable. The whole point of a display surely is the ability to display things - why limit it? Hell I still use S-Video from my Sky box to both my plasma and my projector. (as well as HDMI (PC), component (wii), VGA(PC to plasma), 2nd S-vid from DVD/VHS recorder, composite (Gamecube)

Maybe I should throw all that kit away and get HDMI everything and upgrade my displays and consoles as well, sure I've got a spare 5K lying about to accomdate all of that, or maybe the manufacturers could just put a variety of video in ports on there equipment.
