HDMI / HDCP with 2560 x 1600 Support?

post #1 of 15
Thread Starter 
Hello - I have searched and googled (a little), but can't seem to get this clear in my head.

I am looking to get the HP LP3065 Monitor that supports 2560 x 1600 resolution for my PC. Of course I want to watch protected HD content (HD-DVD / BD).

This Monitor claims to support HDCP. However, all the current video cards that I know of do not support HDCP over dual link. They will support HDCP over single link.

When I searched for info on whether HDCP / HDMI is supported at all with 2560 x 1600 resolutions, it was not clear. It seems that to support 2560 x 1600 the chain of equipment will need to support ~ 285 MHz of bandwidth (Resolution X Refresh Rate X Blanking Period of 1.16). The Monitor can handle that - the Video Card can handle that - the cable can handle that.....but is there a limitation of the HDMI 1.1 / 1.2 spec? All I can find is that 1.1 / 1.2 supports 1080P at 60 Hz which is only ~ 145MHz of bandwidth.

What am I missing? Do I need to simply use DVI with HDCP and not go the HDMI Route?

Any help is appreciated.

Seems to me while the HD-DVD vs. blue ray debate lingers, there may be some shaking out to do. MS's Ballmer states Windows Vista, the next gen OS system (in case you've been out of the country for a while) will not ship with blu-ray support, giving HD-DVD support the initial nod - it goes on to say it "may" be at a later time. The caveat being the platform with the most support in 12 to 18 months. That won't prevent a third party from developing an application for early adopter/computer HD viewers.

I recently placed an order for this monitor: Although the DX9 specification works, I believe DX10 will be required for Protected viewing of blu-ray/HD-DVD and while that may not be accurate, certainly to take advantage of all the depth of HD.

Anandtech has an early review of DX10 enabled cards, including the immense amount of power some of the DX 10 GPU will consume. The power supply companies will, no doubt, experience a windfall from the upgrades as a result of those of us who build and update systems.

I copied the following from the Nvidia help forum :
SUBJECT:
Blue-Ray/HD DVD playback issues with Dell 3007WFP and Hewlett Packard LP3065 30" LCD monitors

Question:
My PC is HDCP compliant. When I attempt to playback content protected Blu-Ray or HD-DVD movies on my Dell 3007WFP or Hewlett Packard LP3065 30" LCD monitor, I receive an error message that my PC is not HDCP compliant. How do I correct this?


Answer:
The Dell 3007WFP and Hewlett Packard LP3065 30" LCD monitors require a graphics card with a dual-link DVI port to drive the ultra high native resolution of 2560x1600 which these monitors support. With the current family of NVIDIA Geforce 8 & 7 series HDCP capable GPU's, playback of HDCP content is limited to single-link DVI connection only. HDCP is disabled over a dual-link DVI connection. The highest resolution the Dell 30" 3007WFP supports in single-link DVI mode is 1280x800 and therefore this is the highest resolution which HDCP playback is supported in single-link DVI mode on current Geforce 8 &7 series HDCP capable GPU's. On other 3rd party displays with a native resolutions of 1920x1200 and below, the graphics card interfaces with the monitor over a single-link DVI connection. In this case, playback of content protected Blu-Ray and HD-DVD movies is possible on HDCP capable Geforce 8& 7 series GPU's.

There is some hope though: dv411(dot)com is selling converters which may provide the adaptation necessary for the giant monitors coming our way. The $450 price tag is steep, IMHO, but that doesn't mean there isn't already competition in the converter arena of that prices won't plummet once the converging technologies and trends gain momentum.

I am not sure what you and/or Balmer mean by Vista having HD DVD support. MSFT is leaving it up to the 3rd party applications to take care of HD DVD playback.

I believe the media player in Vista will support all standard codecs it supports now, but also MPEG-2 and VC-1. So if you have HD-DVD drive with a VC-1 encoded movie, Windows Vista media player will be able to play it. However, a H.264 HD-DVD or bluray disc will require separate software.

That's what I gather anyway.

My new laptop has built-in HDMI port with HDCP (ATI X1700). The laptop also has a 1920x1200 built in screen and HD-DVD drive.

Anyway, I'm thinking of getting the Dell 3007. Can I drive a 2560x1600 desktop using HDMI?

Btw, the laptop is an Asus W2P which I dual boot into Vista Ultimate 64-bit or XP MCE, depending on what I'm doing.

You can not provide the full 2560X1600 over HDMI. The Dell 3007 requires a dual link DVI.

I suspect that my laptop has a HDMI 1. 3 connector. If that is the case, it supports up to 10.2 Gpbs. Dual link DVI is 9.9Gbps I believe.

So I guess the issue is that no HDMI -> Dual-link DVI cable exist?

I think I read somewhere that a "Type B" HDMI connector exist that is dual link of sorts and support up to 20.4Gbps, but that nobody is considering using those (yet)?

Bump for pclausens question - I have the same issue - biuing an HDMI 1.3 notebook and want it to drive the new 30" displays in native res.

You're out of luck until someone makes a monitor that accepts the new higher speed HDMI protocol. I also wouldn't be too sure that your notebook actually supports it either. They can advertise it as HDMI 1.3 without actually supporting all of HDMI 1.3's features (ie: higher speed).

any update on this? I bought a laptop with hdmi only and would like to know if it is possible to use a 30" screen at native res. please explain, thanks
post #12 of 15
I'll try one last bump on this as I'm in the same boat. Are there any 30 inch displays at this resolution that can support HDMI 1.3? or alternatively a way to interface (via cable or some other way) between HDMI1.3 and Dual Link DVI?

Thanks in advance!

I have just run into this problem unfortunately. The Dell 3008WFP monitor does not seem to support HDMI version 1.3 which is needed to display 2560x1600 desktop resolution. Using the dual-link dvi cable does allow 2560x1600 but no blu-ray playback as dvi is not hdmi compliant. However hdmi does not support 2560x1600 until version 1.3 (apparently) but that means having a monitor that supports hdmi v1.3.
At the moment I am having to use a trial version of Slysoft's AnyDVDHD so that I can play blu-ray on the dvi enabled 2560x1600 desktop.
In other words, be careful and hope that some solution other than paying $A150 to use 2560x1600 on the desktop and play blu-ray turns up.
And I can tell you that a scaled up 1920x1200 desktop on a 30" screen looks very poor indeed, and an unscaled 1920x1200 desktop defeats the purpose of having such a screen in the first place and also looks ridiculous. Cheers, catonic.

I think the Dell 3008 has issues with HDCP over dual link DVI. There's another thread about it somewhere. Most modern graphics cards support HDCP over dual link DVI.

There's the Gateway 30" display with the great built in scaler/deinterlacer.
