VGA -> Component (Key Digital KD-VTCA1) - What do you think?  

post #1 of 10
Thread Starter 
Has anyone used the Key Digital KD-VTCA1? It seems like the best VGA to Component transcoder. It seems like it does auto switching of resolutions. They priced it around $159. What do you think? Also, anyone know where to get a better price?

Interesting. I would like to see someone's opinion who owns or has tried it out. Is this recommended over the AA?
If I had one to test, I would give you my own opinion.

I have the first Key Digital transcoder & have also tried the AA9A60 and the RCA transcoder. The KD unit is clearly superior in terms of picture quality, no doubt because of the high bandwidth capacity. One thing I noticed on this new unit: although is does tout its' auto resolution switching capability, when the unit is in auto sensing mode, the horizontal positioning function is disabled.

Karnis:

What does the horizontal position function do?

How do you use Powerstrip or any other type of utility to control the picture? Does it work well with the Key Digital unit?

Thanks,

The AA does not have any horizontal positioning controls either. I think it is a trade off between auto switching and some control over the positioning, although I can't imagine why. Maybe with manual switching, there are separate circuits for each resolution which makes it easier to tweak (??)

Anyway, I would be interested to see if this takes care of the wavy lines some of us have using the AA and RPTV. I am still holding out for a video card that can do YPbPr natively (damn you Radeon,) but this might be a nice intermediary.

If you use Powerstrip 3, try reducing the vertical sync pulse width closer to "1" to reduce the wavy lines at the top of your image. You can see them get even worse as you increase to a value of 16, then improve with a value of 1. Check this post for my HDTV/PS 3 timings, you'll notice I try to keep the V-sync width close to 1.

Thanks for the link. It seems like it is going to help!

I just installed a new AA transcoder to my PC for my 53" Pioneer (RCA never worked). Compared to the RGB direct HD input for my TV, the DVD images (both text and graphics) looked equal to RGB, may be a little sharper than RGB, Win98 text is a little less legible through AA to component input but I don't intend to have my RPTV as desktop monitor. The benefit is I now have most TV user adjustments, which are not available through RGB input.

Karnis,

Have you actually got them to go away? Even at 1 they are there... and they get worse the longer I have the set on. The lines do get worse as I increase the vertical sync pulse to 16 (or if I increase the number of beers per sitting, but that's a separate matter.)

Maybe my set is just finicky.
