As Larry David says, "You're way off base". Just kidding.... Yeah but MANY people want to use a 27" iMac for watching their 720p mkv files.I know if I was going to buy a new Mac AND I needed a new TV at the same time I would jump on the 27" and equip it with another 1TB.

Right now I watch 720p on my Aquos 40" via PS3/Mediaserver and it is oh so sexy. Although 40" isn't big these days. But if you go bigger then you need to download 1080p and my computer isn't up to snuff for 180p playback anyway.

this is a pretty useless feature as far as i can tell. anyone got any killer apps for this? i can't think of any. using it as a display for a laptop is about the only thing i can think of and that doesn't seem all that useful. the 27" imac is sweet enough to buy one, but i don't think i would ever use this feature.

I agree I would use it for a ps3/xbox or something like that before I'd use it as a second monitor for my laptop.

Btw, I think most Mac users are not aware of Plex because if they were they probably crap their pants.

iTunes who?
post #86 of 150
Yeah, I can understand the whole bluray issue. Thats annoying me a bit...

But this whole video input thing is awesome. By the time that computer is obsolete, it can be used as a second display for your shiny new 50 inch iMac :P, and you can run the computer part in the background as a server or something. This makes the iMac way more versatile.

And if these adapters arrive soon and work well, PS3 heaven :P

A converter box to import HDMI via Firewire or USB would probably cost more than a decent sized HDTV.

That's exactly what I would use it for and it is a very useful feature. I have a work laptop and when I have to do something from home I like to be able to hook up the laptop to my home display. Nothing worse than using a tiny screen when you have a nice big one sitting in front of you. Right now my work PC doesn't output anything except DVI/VGA.

Couldn't you simply connect them with a hub?

I understand that the 21.5" iMac does not support input only output. Would that be changeable through a software update if Apple chooses, or will they need to bring out a new line? And why don't they just add that option to the 21.5"?
post #96 of 150
I could see the mini DisplayPort input function targeted at laptop users and maybe future tablet users. The modern MacBook Air sports a MDP. Also the current MacBook and MacBook Pro.

http://www.apple.com/macbookair/specs.html
http://www.apple.com/macbook/specs.html
http://www.apple.com/macbookpro/specs.html

All you need then is the $30 cable with MDP at both ends
http://store.apple.com/us_smb_78313/...co=MTM1NDg4ODQ
or
http://catalog.belkin.com/IWCatProdu...duct_Id=508255

Maybe a future iPod/iPhone dock with MiniDisplay Port would be way cool.

Apple has a history of releasing incremental improvements to their products. I am sure a future revision will be more flexible for usage of the iMac as a display. Alternatively, there will be 3rd party adapters soon enough.

@techstud: There is no reason for you to crib about Apple just because they are innovative and don't deliver on all the features in the first iteration of an idea. Nobody is forcing you or anyone else to go out and buy an iMac now or in the future. The iPhone is severely limited in cross application access and multitasking, that didn't stop it from being a successful device. The iMac is a computer that can act as a display for your MacBook when you are at home using the display port adapter.

Belkin is rumored to be working on a converter box for conversion of digital video into the packet switched stream that Mini DisplayPort uses. Nothing on their web site yet. It should be a Command-F2 away in the future.

They probably didn't put the hardware in the 21.5 inch to keep the price down, and to make the 27 inch more attractive. Switching it to IPS probably reduced their margins by quite a bit I would imagine.

They have converter boxes that send DVI over ethernet. There is a little loss of quality and a little delay as the graphics data has to be compressed. There is no software to access that signal on a computer however.

I have a USB display hooked up to my mac so I can run 3 displays, and when running windows in bootcamp I was able to play Half-life 2 on the USB display at 1024 x 768 at over 30 fps, zero lag. (uses the primary GPU for rendering).

I'd figure full high def would be easily accomplished with gigabit ethernet or fw800, however I doubt you would ever see that because it would require decrypting HDCP to be of any use and thats a big no-no. Really, its HDCP that makes converting DVI to DisplayPort require any real effort. Blame the DRM.

But for sure its totally possible and probably with minimal lag.

I don't see why it's unreasonable to suggest that Apple would make more money with a elegantly designed box to convert HDMI to mini-displayport. I have two MacBook Pro's and a MacPro Octo. I'm plenty happy with Apple. I'm not pissed at them or anything.

Here's my deal. I don't have a flat screen TV yet. I'm anxious to get one; when I heard the iMac announcement about video in; I thought: no reason to buy a TV now. I imagine an HDMI hub maybe with a remote, maybe keyboard switched, maybe an iPhone remote for it, all terminating at the iMac on the wall. It seems there are other ways to accomplish a similar goal: Sling Box comes to mind. Still, I will want a console at some point and will want the lowest latency possible.

So, I don't particularly need another computer. For the same price, I could probably find a decent and larger flat screen of some description. Still, having an iMac as a family hub for any and all video inputs: super cool. I can't remember the last time I've posted here, I just read all this harassing stuff when the underlying point is valid: Apple might have gone ahead and taken this Beast to the next level.

You have to understand, within some circles of the Mac community its considered unreasonable to want anything other than exactly what Apple gives you.

I guess! I have never understood Apple's fascination with proprietary i/o; FireWire excluded. Maybe DisplayPort will enjoy wide adoption. I'm thinking back to the, what was it, Apple Display Connector? $99 for DVI. When they went to DVI, I was enthusiastic.

Fanboy? Somewhat. Siccophant(sp?), not so much.

Two theories:

A) every so often Apple wants to impose its ideas on the display arenas and releases a new connector. Every time, however they have failed.

B) They want to do everything they can to restrict you into buying their own displays.

DisplayPort is the next big thing in PC land, the flagship ATI Radeon 5870, 5850 etc. DirectX11 cards all have DisplayPort and you need DisplayPort to drive

But the "mini"fying of DisplayPort, yeah, Apple likes to roll that way with their connectors sometimes... Can't say much wrong about Magsafe though... I bet you there are laptop companies out there dying to license or reproduce that technology. It in fact should be a new electronics standard while waiting for induction/wireless charging, etc. to become mainstream. WiFi for wireless, what about for charging wirelessly? I recommend the name WiPow. Wireless Power, get it! "WiPow certified"... OK sounds a bit silly, but so does "Magic Mouse". Maybe WiCharge. Or WiJuice.

It's Apple, master of sending out mixed messages. (See: AppleTV, MacMini, iMac, MacBook Aluminium pre-MacBook Pro 13", Cinema Display 24", 30"... and so on)

NO ONE in any of the forums has shown any proof that the 5870 display port out works with the imac 27'

One guy claimed he had it working and when everyone asked for photos he disappeared.
One guy claims his 5850 does not work though. (this is all using a mini dp to DP cable)

I do not think this display is working with even displayport equipped pcs.

The spec is the spec. DP signaling is the same as mDP signaling. Unless there is problem with the card, its driver or the cable, which is possible since this tech is still pretty new, then they will work.

If it did then it would be a fine thing. The fact that when using a DP to mDP cable the ATI 5800 series is currently incompatible with the mDP input on the Apple 24" LED is not encouraging.

Not exactly sure what you mean. As was said before, DP/MDP is interchangeable according to the specs. Do you have a link that shows that the DP on the ATI cards don't work on the iMac? Don't get me wrong, it SHOULD work but since Apple seems to be clearly intent on preventing people from using this display with anything but a MacBook I won't be surprised if there is really is a problem using the iMac with these cards.

I don't have anything regarding the iMac - links to 24" LED and ATI 5800 below.

Okay, so what are the practicalities of this thing in the real world.

If I want to use it as a second monitor, I plug my MBP in and what happens?

Do I have to boot the iMac in a special mode, like Target Disk mode or something? Or do I just boot the iMac normally, and connect it up. If so, what is the iMac doing in the background? Is it just sitting idling whilst I only really use its panel?

Also what happens if I plug a USB device into the iMac? Does it appear on my MBP's desktop? Probably not seeing as how there is not physical connection between the iMac and my MBP, except for the mDP cable. Is so, that means that I can't even plug a keyboard and mouse into the iMac and expect it to work with the MBP.

I'm a bit confused about how this whole video input breaks down in the real world...

I bought the iMac 27" a week or so ago with the intention of using it also for an external display for my gaming winbox.....followed the forums and folks with limited knowledge of how exactly the iMac mdp in works.....seeing there are not yet any dvi=>mdp converter/scalers for the iMac decided to upgrade video card in winbox with ati HD 5870...ordered the mdp to dp cable from newegg http://www.newegg.com/Product/Produc...82E16812270262 and hooked the pc to the iMac.....for the curious, with the present ati drivers or some other incompatibility issue the iMac does not go into target display mode.....the iMac screen will go blue when command + F2 is used and then flash back to mac os on iMac....if you try the command a few times the iMac then will freeze up and a hard reboot is needed...so the assumption is correct that a pc equipped with dp ( my case the HD 5870 ) connected to the iMac 27" mdp does not at this time work...oh well, waiting for update on whether anything other than a Mac to Mac works

That does seem quite pathetic on Apples part. I understand that GPU they are using doing have this capability by default, but why even advertise it until you can get input to work effectively with DP. Unless there is a missing piece of the puzzle. Since I still havent seen any data on how the input is actually handled we cant really say. They did have some initial driver issues with DP when they first added it to their machines.

Thank you for this. You just stopped me from ordering one.

I hate this BS with apple and having to struggle to get the "advanced" features to actually work.

I love the products but tired of the lack of support for the advanced user.

The display is amazing to say the least and am willing to wait to be able to use as an external display for gaming rig......sure it will happen.

btw noticed something different with the sl upgrade to 10.6.2 and how the winbox ati Catalyst Control Center accepts the cmd+F2 from the imac...notice in the pic "System settings have changed. Catalyst Control Center is synchronizing. This may take several seconds." Though ati still does not recognize the iMac it is now trying and says so after the sl upgrade, this did not happen before the upgrade. The 2 monitors are both dells in pic but there should also be the imac..



noticed also that when cmd+F2 is pressed both the dell monitors and the iMac go completely black and while the iMac stays black the message above about syncing comes up on the dell displays.....after the sync fails all monitors return to normal...

think it is up to amd to start pumping out some compatible drivers and we might actually have something

oh well again....still waiting
post #119 of 150
Make sure you go to the official ATI forums and let them know the issues.

Have you tried the 9.11 beta drivers?

Also it has been confirmed the apple cinema display does not work on the 5XXX series but did on the 4xxx with the display port.

It was mentioned earlier in the thread. So far, everybody is trying to connect DP output to MDP input using a MDP to DP cable.

Of course I have no way of knowing this, but it may be possible that for some reason the available MDP-->DP cables do not also function in reverse as DP-->MDP cables.

I strongly suspect that this is the issue here, and that it's not the fault of the iMac or any DP output device.

And I also suspect the only reason the Atlona and Gefen DVI-->MDP converters don't work is that they don't support the iMac's resolution. Once Atlona or Gefen develop a dual-link resolution capable converter, I think we'll see things working as we would expect.
