I also own a Toshiba HDTV and have had *ZERO* luck getting the picture to align correctly (its about, 75 or so pixels to the left, just enough to bug me) :) Could you do me a favour and post the settings you used in DisplayConfigX? What model Toshiba do you own? Thanks again!! Johnathan,

There were directions on the ATI website that said using this adapter, it had to be the one and only display connected, and that it was necessary to boot in that configuration. I tried that several times, but got no signal. Of course, those instructions were for Windows boxes.

For some reason, I think OS X is not supporting the proper Y/Pb/Pr output. In fact, even the DisplayConfigX website says it does not support these outputs.

Time to sell my adapter to the PC crowd on Ebay and try something else, such as is described above.

Using TI powerbook and vga to component adaptor and switch res x was able to tune in a perfect picture on my 60 inch Hitachi LCD rear projector NO under or over scan. Wrote down the reading, entered them in a mini and couldn't get a picture. Heres the problem. The powerbook senses the built in display and I was setting up on the attached display. This always gave me a working display to work with and make changes. The vga to component adaptors work but give no feedback to the computer on what type of display is connected which lets the computer guess badly and produces unusable resolutions. Thats why I could not get the mini to work. The tv was the only display and it could not be sensed. Connecting the mini using dvi solved that problem. Now the mini showed HITACHI RPT and automatically selected usable displays. Now that I had a picture I tried the TURN OVERSCAN OFF. Now I hadd a 1 inch black border all around. I was not willing to give up all that realestate so I turned overscan back on and set up a custom resoultion under switch res x. Now if you don't believe anything else believe this. Find out what the native resolution of your HDTV is and start there. On the Hitachi is is 1280 by 720. That means 720P scanning. Therefor use a 44 hertz(this rate causes the tv to go to 720P) horizontal rate and a 60 hertz vertical rate ( give or take a hertz). Put about 50 in all of the porches, about 135 in the horizontal sync and about 5 in the vertical. Load it up and reboot. After restart select the new resolution and take a look. Go back to the custom menu and start trimming. The sizine arrows on the right are very nice. Remember that the position arrows on the top right work just backwards. If the picture needs to movve down then use the up arrow. Etc. Width and Height work as expected. Save it, reboot, and try again. Remember that you must switch in and out of your new resolution a couple of times. This is because your resolution may not take effectunless it is turned on and off. If your custom resolution disapears after a reboot in the monitor pull down list the you have exceeded some realistic value. Go back and change back to an oldeer value and try again. Once you have it working use the switch res x panel that lets you define the relolution for the detected display (Hitachi PRT in my case ) and select the one you made. Now when the Tv starts and DVI detects the display it will use the one you made. Now go and spend 300.00 for a 2 in one out DVI switch because your tv only has one dvi input and you are ready. So what values work. Every video card and every tv will produce a different value. The values I had on the power book with the vga to component adaptor were different than the DVI from the Mini on the same tv. Every tv overscans different and centers the picture different. There are no canned values. Good luck, patience, and time and you will have a very pretty picture with no over or underscan. Tried both vga to component adaptor and direct dvi.

Though I literally upgraded the machine to Tiger today - since my non-standard display (the TV) would not run the default screen res to let me install an OS previously. My new 20 inch panel was able to pinch in. Tiger actually has an option to tweak whether you want overscan on or off so that might actually help us both.

If you figure out some magic settings I'd be very inteerested in hearing what you got to work. Like I said, I never quite got it.

I managed to get my Toshiba and mini to play nice using a transcoder and DisplayConfigX. It wasn't perfect, there was still a bit of overscan, but quite usable. Then my harddrive died w/o a backup and when I got it all put back together I could not for the life of me get the display configuration right again. Then I found a posting on AVS forums that caused me to buy a DVI to HDMI cable, and most important, a copy of Tiger. In Tiger there is a new checkbox in the display configuration that allows you to turn off overscan. After loading Tiger OS X the system recognized the 62" Tosh and once I turned off overscan the picture was perfect with a nice thin, even black boarder all around. Much easier! I sure hope this info helps someone avoid the pain and frustration I went through. Devros; Yes, that is the crux of the biscuit isn’t it?

Thanks for the info and quick response. I guess I can always pick one up and give it a try. I'll search around a bit more and see if I can find anything online. If I can't, I'll definitely let you all know if it works out for me. Ah. Thanks for the info and quick response. I guess I can always pick one up and give it a try.
