Splitter

Theoretically is it possible to get an HDMI port replicator (sorry if I am using incorrect terms) or HDMI splitter to run the PTV2000 to 2 tv's?

Theoretically it should since all the PTV2000 base unit needs is the EDID information from the TV to set the output resolution, which the HDMI splitter should be supplying. I've not tried it, but here's what I think you would be looking for to do this:

Thanks much for suggesting that. I talked to someone at Best Buy and they suggested something and said that maybe there might be some loss in resolution, but it is really only going to be used as a method of having another 32" full 1080p HD tv as a monitor. I can fit 3-4 full view word documents with this one unit right now. Having 6 files open like that would be great and the resolution if only lost a little quality it would be fine. I saw this one on Amazon:


input HDMI V1.3 signal can split to 2 HDMI V1.3 signal identical to the input signal m Support deep color 30bit, 36bit, blue-ray 24/50/60fs/XvYCc

Digital audio format, DTS-HD/Dolby-True-HD/LPCM7.1/AC3/DTS/DSD
Max bandwidth : 10.2Gbps; Support signal retiming; support CEC
HDCP 1.2 Protocol Compliant; Support output HDMI 1.3 cable up to 50 ft; Full-HD 1080P cascade above 4 layers


Does any of this technical information indicate anything? I also have been buying Amazons HDMI cables and Toslink for something like $12 for the pair and they are 6'

Does this sound like anything worthwhile:
HIS HHDMI4067 DVI/HDMI Adapter for ATI Radeon HD 2000 Series
enables HDMI output (Video and Sound) from compatible ATI Radeon HD 2000 (2400Pro, 2400XT, 2600Pro, 2600XT, 2900Pro, 2900XT) Series Video cards.

My card is a separate Radeon (TM) HD 6770M 1 gig dedicated.

Again thanks much for help.

Normally you don't have to worry about a loss of resolution unless the splitter doesn't support the max resolution you are outputting. The splitter you listed looks great, and should easily handle what you want to do.

The DVI-to-HDMI converter with the ATI Radeon 2000 series will work for pushing out the video and audio to a TV, but I think is a seperate question from splitting the output of the PTV2000 base unit. i.e. The output from the base unit is HDMI, and doesn't have anything to do with the DVI-to-HDMI converter connected to the video card.

In your scenario of having 2 video cards running simultaneously in the same system along with the PTV2000 drivers, there might be an issue. I've never tried it and haven't seen any post of someone who has, so there might be an issue of the driver not knowing which video signal it is suppose to duplicate. On the laptops that support the PTV2000, if it has an add-in video card normally you have to choose which card you will use (add-in or on-board). In your case it has 2 valid signals, so I don't know what will happen.

Since HDMI is digital, there is no loss in resolution or clarity - so that info from Best Buy is not really correct. Also, if you are simply splitting the PTV2000 output signal, you will see exactly the same thing on both monitors. So you won't get to see more documents.

The splitter specs look fine, though sometimes HDMI splitters/switches will interfere with EDID negotiation. It is hard to tell yours will have that issue unless you try it. BTW, it doesn't claim to support 3D - that is not an issue with the PTV 2000 of course. But your Radeon graphics are supposed to support 3D.

The Radeon adapters are for connecting your PC directly to an HDMI TV (with sound). They don't claim to work with your Radeon card, only with the 2000 series graphics cards. If your laptop has displayport or HDMI out, then you certainly don't need them. If you only have DVI out, they might not work (that is, you might not get sound on the same cable).

What laptop is this?

Normally a WiDi machine with Radeon or Nvidia graphics would have switchable graphics. So when the PTV2000 is running, the Radeon is disabled, and you use the Intel HD graphics only. This still allows multiple display output, though of course only one is sent to the PTV 2000.

Your right, I was thinking more of the PTVU1000 when I was thinking of the possible problems. With the PTV1000/2000 it is limited to only working with the Intel graphics chip, but I still wonder if you have 2 simultaneous video outputs from 2 different video cards, will there be an issue?..
