Lucid Virtu-like features without Z77???

Hi all,

So one of my friends has a Z77 motherboard and is using his Intel HD 4000 graphics through Lucid Virtu on his Z77 for his video rendering / encoding / transcoding. Now I have a B75 motherboard... so obviously its not a Z77... so most probably it won't support Lucid Virtu... but he told me I could take advantage of the integrated graphics of my i3 2100 (HD 2000) for that same feature of Lucid-Virtu (fast rendering / encoding / transcoding).

Now I'm currently running my display off of a Radeon 6850 through the DVI input of my screen (its a budget gaming machine).

His method: Get a VGA cable, connect it to the screen and to the VGA connector on the motherboard. Then simply enable the integrated graphics. Whenever I want to go from gaming to video rendering / encoding / transcoding, simply switch my monitor's display from DVI to D-sub (via the buttons on my screen) and I'm good to go!

So:
1) Is the above stated information correct? Is this method valid? Can I really take advantage of the onboard graphics from my non-Z77 motherboard?
2) Would any problems arise?
3) I'm trying to do this right now... but from some reason, in Device Manager > Display Adapter, I can only see my Radeon 6850, there is no icon for the integrated graphics indicating it is disabled... uninstalled maybe? Just requires driver installation?

Any help would be much appreciated,
Thanks

if you are looking for a cheap way to use quick sync you just need one 75ohm 0.7v resistor

if your motherboard does not have a dvi output then you need three to simulate a vga connection

a side view when using a dvi/vga adapter:

now on a side note, i used virtu on my motherboard since the H67 supports it, though not licensed. you can see if your B75 supports it but i didn't find anything overly exciting about it and deleted the trial version. (and i have an old CRT hooked up anyhow)

also you will not be able to use your onboard graphics until you have a monitor (simulated or not) connected to it.

I'm confused... why would you ever want to use the integrated graphics instead of the discrete card for anything, especially when the integrated card is as weak as HD 2000 (very, very weak and not even comparable to the HD 4000)?

I don't think what your friend told you is actually going to do anything useful... and I don't know of a way to simulate Virtu without the proper motherboard chipset. It's not a big loss... it doesn't really do much reliably yet.

Neither Nvidia CUDA, nor AMD Accelerated Parallel Processing is remotely a match for Intel Quicksync, if you call reducing time taken to transcode a video by at least 2 times a feature, then the HD graphics definitely have that feature.
