Default ATI Radeon 7000 ?

I found an ATI Radeon 7000 (has DVI port) card locally and was wondering if it might also work with my HDTV. Although somewhat familiar with computers, I do not have any first hand experience tweaking video cards . Specs suggest that it has the capabilities to display up to 1920 x 1440 so I am thinking it might support a 1080i format. Appreciate your thoughts on if this model might also work as yours has ??

The same store had my same RCA 50" DLP model running on a DVI feed (with a more expensive video card) and it looked incredible..

I'd hate to say that it would and then it not work. The only 7xxx Radeon card that I know works with HDTVs is the 7500 PCI.

Alright, maybe someone already ask this, so sorry beforehand.

I purchased an RCA Scenium, I think is a 50 something, and i absolutely love this thing, and I want to plug my PC to it, and I found two way to do it, one is with the DVI conector, the other with an adapter from ATI that plugs on the card and then I have to use component cables. Wich would be better? what would the problems be? would I be able to crank up the resolution above 800 600?? and in case i do it with the DVI cable, wich type should I use?? I went to Fry's electronics and the have several different types, all pretty expensive I may add, so I'd hate to spend money on something I won't be able to really enjoy. Oh, and since this is my first post, I'll introduce myself, name is Leo, live in Houston TX and love technology, even when many times I can't understand it.

Those timing values are for powerstrip. The moninfo program is intended to be used in conjunction with powerstrip not the nvidia drivers. You will need to download and install powerstrip to be able to use them.


What that information does show you is your TV will operate at 1920x1080 interlaced with the powerstrip refresh rate set to 30hz. Also it will support 720 x 480p at 60Hz as standarrd which is good for DVD video.

I have the same TV and I know it will also do other resolutions. I have an ATI 7500 Radeon video card, the DNA modified Catalyst drivers and powerstrip installed. nvidia card you are on your own.

Here are the resolutions the TV will do:
720 x 480p at 60Hz
960 x 540p at 60Hz
1440 x 540p at 60Hz
1920 x 1080i at 30Hz

Breakdown of the paramerers for powerstrip:
Modeline................ "1920x1080" 74.250 1920 2008 2052 2200 1080 1084 1094 1124 interlace +hsync +vsync

Modeline................ "1920x1080"
74.250 = pixel clock
1920 = video memory pixel width
2008 = add 88 pixels for front porch
2052 = add 44pixels for sync width
2200 = add 148 pixels for back porch = total horizontal pixels
1080 = video memory pixel height (scan lines)
1084 = add 4 lines for front porch
1094 = add 10 more lines for sync width
1124 = add 30 more lines for back porch = total vertical pixels
interlace
+hsync +vsync

You can try plugging in the values shown and see what happens. Some drivers will not let you enter the numbers exactly as they calculate what values should be for a given resolution. Normally what you do with powerstrip is use the string returned by moninfo to set the powerstrip timings to bypass the manual entry. It may be you can't get the values to match exactly due to the way your nvidia card works. It should work the same with the nvidia card and powerstrip except maybe slightly different values.

Ninja750 sorry to have not seen your post before now.

In order to give you the best info I would need the model of the TV and the details on your PC. Apparently you have an ATI video card. As far as I know the ATI cards that can support HDTV resolutions are the Radeon cards. I use a 7500 pci card and I have the DVI connected to one of my TVs and I use VGA to component adapter on the other. I can not tell much difference between the two different connections. The component connection route seems to yeild a bit less flicker.

Either connection will cost about the same money as the ATI adapter is about $30 and component cables can be had for $20. You can get a good quality DVI cable for around $50, so expense wise it is a toss up. I tend to favor the component route as it leaves the DVI for other devices like a DVD player or a HD STB which needs the DVI video more than a computer.

Get back on the TV model and the PC specs and I'll be able to advise you further.

Ok, here I go.......

I custom made this PC, but here are the specs.

AMD Athlon 2400+
512 MB of DDR ram
ATI Radeo, 9600 SE, with VGA and DVI output, AGP 8x
Windows XP home
Two HDD, one 120, the other 60 gigs

DVD drive and a Pioneer DVD burner.
The MB is an ASUS, can't remember the model, but it has everything integrated, with the exception of the graphics,

Hope this helps!

You should be able to use the DVI connection just fine.

Great!, but now i have another question, my TV won't accept an DVI-I cable, only a DVI-D, but my video card can accept both, but when choosing the DVI-D, should it be single link or dual link??

Well here is the stuff Moninfo gave me. I got power strip and fooled with it for quite awhile with no luck. I want what nvidia calls as a clone setup so that what is on the monitor shows up on the tv as well. Not dual view where u can drag windows onto the tv as a 2nd desktop. I tried going into the nvidia program and set it to clone view and then go to powerstrip and enable multiple monitors and it sets it back to dual view so I cant win! And ontop of that I cant seem to get the display for the tv with powerstrip to work at all. I guess I'm a noob any suggestions?

Will Redaon 9200SE(has VGA, DVI and TV-out) work? with a DVI-to-component adapter?
Also, is Catalyst driver a MUST?

I have used a 9200 card with the same drivers as I use for the 7500 Radeon card. I have the Catalyst drivers installed with powerstrip. I don't know if they are a must, but may very well be to get the HDTV resolutions.

How come when I run Moninfo, it doesn't give me any information about the TV? I used the VGA output from my video card to my TV's VGA input, which is fine; and I'm using the DVI output from my video card to one of the component input on my TV at the same time, would that be a problem? I switch between the 2 inputs where the VGA one is ok but the component one never worked.

Just can't get it to work
