Well, I've posted this in other forums and had good response....thought it should be here too. I have a Radeon 9600XT card in my HTPC and use PowerStrip so I think applicable. This How-To is to show a example of alternative way than having to deal with clone mode, etc. The idea is to have one debug/viewing FP monitor on your HTPC and one (or more since I go thru a 8x4 component matrix switch) TVs/PJs.
I have a Home Theater PC Video Server that runs TheaterTek software player with XLobby front-end to make it nice and clean looking to user. However, for me and anyone else that wants to solve the physical
connection to my/your MULTI
Mon/TVS/PJ setup here is how I achieved it. For me I use this setup because my HTPC is in another room from the TVs/PJs so I want to have a Monitor at the HTPC which will be exactly what I see on the TV/PJ without all the hassles of trying to get clone modes to work.
1) Buy a VGA video active
get simple RGB Y cable) splitter....they are cheap...$24. This will allow you to hook up your current PC monitor and have a second output. This is simply connected to the VGA 15pin DSub connector on the back of your gfx card. The first output of this splitter goes to the monitor located at the HTPC. Here is one link but if stale just do web search on "Tripp Lite VGA/SVGA Video Splitter B114-002-R - video splitter - 2 ports
2) Buy this VGA to Component Transcoder. Hook the second output of the above splitter to this unit. The output of this unit goes to say the 2nd component input of your TV.....or if you are like me into a Matrix switch that feeds all my TVs. Again here is one link but if stale just do a web search on "Audio Authority 9A60 VGA to Component Video Converter
3) Lastly, on the PC you can change your video driver to 720P. Most Gfx cards have this driver setting...it is merely 1280x720 60Hz. Your PC monitor should accept and the TV will be driven (via the transcoder).
Lastly, as you know from this forum you'll need to tweek the above driver thru PowerStrip to reduce the overscan of component (~7%). I'm sure everyone here knows the links but for FYI:

I hope this helps.
P.S (Matrix Switches). If interested like I achieved you can drive many TVs/PJs in the house thru a component matrix switch. There are alot of them out there but beware the cheap ones do not have the video bandwidth or low noise you need....you get what you pay form. Video Storm makes a very nice series (6in-2out or 8in-4out). This is a full matrix to you can route ANY input to any output all independently. You can program the IRs it recognizes to anything you want, even split the audio from video if you want. For me, I have all my A/V hardware in a single rack downstairs in my Home Theater (settop boxes, HTPC, DVD player, XBox360, etc.) connected to this and it routes to all my TVs/PJs....thus any TV can access any piece of input hardware with only one component cable set going to a TV. Since component can run 100ft+ it allows for support of remote TVs without any hassle. If your comment is "yeah but I want one of my TVs HDMI" then OK....the CRM84 (8x4) even has a extra card to matrix HDMI/DVI. Now, remember HDMI/DVI is only speced for 15ft. and beyond that you risk pixelation....however you can add a repeater which will extend to 200ft....this is much cheaper and better than the HDMI optical cables or cables with repeaters built in. Here is a couple of repeaters:http://www.gefen.com/kvm/product.jsp?prod_id=2939http://www2.dvigear.com/accaexhd.html
Lastly, in all this if you are like me and have distributed TVs around the house and the rack is somewhere else you'll need to put in IR sensors in the rooms. These are very small and only few small wires running back to a small box near the rack. Out of this box will have the translucent IR emitters that go over the IR windows of the electronic components....even the matrix switch. This way any IR command from the remote goes to the sensor, down the wire, to the pickup box, broadcasted out over the emitter wires to all your electronic components and the one that knows/understands the code responds. So, with a little programming of IR macros on your universal remotes you can have one button for say "DVR settop" that changes the matrix switch to route to that box to that TV, turn on the DVR, etc. Makes for a great WAF. There are many IR pickups/etc. out there but one of the easiest is by Xantech: http://www.xantech.com/products/ir_products.htm
This works well with the above How-To obviously connected to the output of the VGA trasncoder box. Here is the one I have:http://www.video-storm.com/proddetail.asp?prod=CRM84
