I have a Dell XPS 420 with a dual DVI video card:
TP073 nVidia Geforce84, PCI-e X16, 512M, with Dual DVI and HDTV out via dongle, HMGA15
I've recently upgraded to Windows 7 Ultimate (32Bit)
I'd like to use my Sony Bravia KDL-46XBR3 as second monitor, as a clone of the primary monitor, a Dell 24" widescreen. http://www.docs.sony.com/release/KDL40-46XBR2.pdf
My current configuration uses a VGA adapter on one of the DVI plugs to the D-SUB input on the TV for Video and a splitter on the audio cable to send the audio over.
After the upgrade to Windows 7 (from Vista Home) I no longer have access to the resolution setting that allowed both monitors to operate where there were no bars on either screen. I believe the resolution that works best is 1440x900. But I can't get that as an option in my resolution settings. (Reading the list of supported resolutions in the TV manual 1440x900 is not listed, yet that did provide the best setting for both screens)
Is there a way to have independent resolution settings for a cloned screen config? Would something like UltraMon be the ticket? http://www.realtimesoft.com/ultramon
Now, no matter what resolution I chose, I cannot get an adequate display on both screens at once -- either one or the other (or both) will have significant banding (Black bars - either top/bottom or on the sides or both).
And I'm also dis-satisfied with the headphone splitter on the audio cable solution as well.
So I thought maybe a new video card with HDMI out to the TV would be better.
What do I need to do to include the audio onto the HDMI out of the video card? Will it affect the regular audio output from the sound card? I'd like to have both my PC speakers and the TV audio fuctional, but not at the same time.
What would be a good video card with DVI and HDMI to replace in my system? $200 price point.
