Problems with multiple monitors.
I have the following configuration:
- Latitude D600
- D/Port APR
- DVI-D to DVI-I adapter
- DVI-I to Component Video Adapter
- RGB Video cable to my TV
I get no output to the TV. When I go to Desktop/Properties/Settings/Advanced/Displays I see four possible displays, Monitor, Panel, TV, FPD. All except for Panel are grey and
not selectable. Under Desktop/Properties/Settings/Advanced/Monitor I see 4 instances of "Default Monitor". It appears to me that the systems acknowledges that there are connectors for 4 possible displays,
- built in Panel
- VGA for the monitor
- S-Video for the TV
- DVI for the FPD
but only sees the builtin Panel as being connected. I have not tried the VGA or S-Video connectors on my D/Port to see if they are really active or not.
Any ideas???? Is it possible to use the DVI port in this manner ???

- TD,Here is the specs on the DVI-I to Component Video adapter.I assumed this was doing the D to A conversion. Although not mentioned in the Cyberguys catalog, the printed instructions for this device indicate that it was designed to plug into a DVI-I equiped ATI graphics card. I guess it could be designed to use the analog side of the DVI-I connector, in which case it will not work in my laptop application.Based on another thread here I have downloaded and installed the PowerStrip video driver tool. This didn't seem to gain me anything.I have also tried plugging a monitor into the VGA connector on the D/Port. This seems to work as expected. I can configue it to either replicate the builtin panel or extend the desktop across both displays. I appears as though the system is simply not detecting any hardware attached to the DVI connector of the D/Port.Bob.
Update to my previous post.
Additional research has turned up new information. It appears that my assumption about the ATI-HDTV adapter is correct. It is an Analog device and as such will not get any signal from the DVI-D connector on the back of the D/Port APR.
So now to restate my question. Does anyone know of a way to convert the DVI-D output of the D/Port APR to Component Video to feed into my HDTV ????
I have a VGA to Component converter, but the picture quality is less then I would like when displaying a standard PC Desktop.

- No matter what you come out of from the computer you will have to scan convert down tovideo. You won't get any better quality by coming out of the DVI. VGA or DVI will both end
up as the same component signal.What kind of HDTV do you have? Most I see now have VGA and/or DVI inputs.
You must be an early adopter if you don't have those on your set..................TD Yes, I was an early adopter, no DVI of any flavor, no VGA, only Component and S-Video input to the HDTV. HDTV is a crt, not any flavor of flat pannel or projector.
Further research seems to indicate that DVI-D to Component is not possible because of HDCP. The HDCP rules state that any device with both digital and analog outputs must disable the analog output whenever a digital signal is being processed.
I guess I will have to be satisfied with the VGA to Component transcoder that I have. I tried it again last night and was able to configure the HDTV as an extension of my desktop at 1400x1050 (matching the max resolution of my D600 screen) with the transcoder converting that to Component Video at 1080i. Most web stuff looked ok unless it was regular text. But even that was readable if I got within 5 or 6 feet from the TV screen. Lower resolutions looked better, but when you get used to surfing at 1400x1050 it is hard to go back to 800x600.
This will probably have to do until the next HDTV upgrade. By that time I am hoping that everyone will have standardized on the HDMI interface, which takes care of digital video and 7 channel audio and has only one flavor, not like the half dozen different DVI connectors.
Bob.
