Help using ATI Component Video Adapter (dongle) on a sony projection tv

raaaaaa,


I am currently using a Radeon 9600XT with the dongle hooked to the component input of a Sony 51" rear projector. I still have the original 15" monitor hooked to the Radeon VGA output. The dongle is hooked to the DVI output of the Radeon. I have 480i, 480p, 1080i and 16:9 set on the dongle switches since my Sony is 16:9 and will only display the previously set resolutions. I am using Catalyst 4.6 which allows me to set custom resolutions like 1776 X 1000 using 1080i timing.

I always boot up with the VGA monitor working and use the Sony TV display as an extended desk top. I can switch the Sony TV then to being my primary display and it shows the complete desk top and any applications that I might run. Using 1776 X 1000 resolution keeps the desk top from being over scanned.

If you want to boot up with the Sony TV as the primary display, you may have to build a VGA adapter that fools the Radeon card into thinking that the VGA monitor is attached. If you do a search on the VGA adapter you will find plans on how to build one.

If I may ask, can you read the fonts with a resolution so small?

I have read on the forum of other people with the same resolutions and I am dying to use it. I built a HTPC just for this purpose. I am using an S-video cable know at 800x600 and I can't look at the screen for more than 10 min without getting @#$% and switching to my desktop. I want to get full use of th HTPC and get my girlfriend to use it also (keep her away from my gaming PC)


So if I read this correctly you are saying to boot into a CRT or LCD while having my Projection TV as the second monitor and then switch displays.


I will try it out the reason I thought it would work, is because I have read alot of people on the board doing it this way plus I followed an article from HTPCNEWS.COM that detail step by step how easy it would work.


I will try and see if it works


thanks for the help

I've recently just started working on this as well, having just bought a ATI HDTV Wonder and a 9600 by Sapphire (Atlantis 9600 Pro w/256mb), and I'm trying to determine which ATI adapter to buy. Included with the 9600 card was a PS2 looking like adapter to a composite RCA plug. This worked with my standard NTSC TV, and looked like I'd expect-- fair.


ATI makes 2 adapters, the DVI to HDTV Adapter for $29 on their website, which would break out the R-G-B RCA connectors. They also make a 7 and a 9 pin cable for $10 that adapts from this PS2 like connector to R-G-B. Any idea on which would be preferred?


I have 2 HDTV's-- A Samsung 26" that has a DVI port (I'm attempting to borrow a DVI cable) and a Mits that has a wideband component in, (in addition to firewire...)


I really want to take advantage of the pvr like capabilities of the card, but the displaying of the image on the TV is my priority-- I can upgrade hardward parts as necessary.


Any comments would be appreciated!

go with the vga I have been having problems with the dvi

OK,

I have tried everything possible that has been suggested by ATI, htpcnews.com and members from this board.


I connected the dongle to a ATI 9600xt and another projection TV that has component video and supports 480i, 1080i. and it does the same thing. scrambled image


I have also connected a regular LCD monitor and booted to it. I installed power strip and followed the direction suggested by HTPCNEWS
ATI settings


I also followed the directions for using powerstrip
powerstrip instructions

this time after the powerstrip install every time I used a resolution all I got was a black screen


someone also suggested that I had the wrong dongle I should use the VGA one

DVI VGA dongle comparison

it says the VGA dongle is for the radeon 8500 but ATI says I can use the DVI also keep in mind that I used the dongle on a new ATI 9600xt and it did not work either.

this is what my screen look like when it is connected to the radeon 8500

when it is connected to the 9600xt I get nothing


one of the rear projection tvs I am using is KP-43HT20


if anyone has any suggestions please help. I put together a HTPC for the sole purpose of replacing my regular PC. I do not want to resort to using an S-video at 640x480 resolution.


thanks in advance

OK, I GOT IT........


After I put the dongle on another video card ( 9600XT) it booted up fine at 640x480


I have powerstrip running and it looks 10 times better.

but know I want better resolutions. I need it to be able to view webpages and XP windows alot better and play DVD's under Media Center 2005


Under powerstrip I am able to get

640x432 true color 32bit

720x480 this is 16x9 and is no good for me

856x480 this is also 16x9 which I do not need

1776x1000 I can't even see anything (so small)


I would like a resolution around 1024x768

can some one help?
