TV-Out problem (lines ''refresh on tv)

[hayabusa]

Hello everyone

I have an old all in wonder 7500 with 64 mb
I never really tryed the TV out aspect but yesterday i tryed to put it to my tv

I set it up... it was not that bad color wise ect....

****The main problem****
When the screen is black or with color i can see the refresh bar going up slowly......
& it gets on my nerve because i am Pretty picky & i don't like it...

How can i get rid of that???
is there a way?
This is my main concern



Also when i connect my sound to my Out i get a light buzzin (is it normal??)

My sound isn't set to maximum either in the pc i dont know where it comes from i tryed 3 set of plugs....

---------------------------------------------------------------------------------------
But theres an option in the ADAPTER section that can set the complete card to let say (640x480(true color) 56hertz to 120hertz i think)

& many options like so
----------------------------------------------------------------------------------------
thanks so much!!!!

You either have a ground loop problem or noise from another component in the PC.

Try moving PCI cards. If you have one next to the graphics card move it farther away.

Try plugging the computer into the same power outlet as the TV.

Try changing the spread spectrum settings in the BIOS setup.

Try changing the resolution and refresh rate of the graphics card.

my main concern is to remove that refresh bar going up slowly on my tv
it irritates me

So what should i try next

I tryed to put 60hertz & even 56 which was the lowest
didn't change nothing.

I tryed to changed to each resolution under 1024x it didn't change either......

I tryed switching S-video Cable to see if it was my cable
same issue.......


so now what are my options???

You mean a light or dark bar that moves up or down the picture, not that the entire picture is rotating, right? For example, something like:

this:

not this:

like the first picture yes

but not that much it's just 2 or 3 lines coming up ....& it's GRRR I get fixed to that problem too easyly

My video card is a ati all in wonder 7500 64mb it's old but it was meant to do this kind of stuff....


Tell me how can i fix this problem

(I tryed to change Refresh rate, Changing cables, Changing from S-video to RCA, & changing resolutions many many times)

I don't know what's left to do....
+ i boosted the anti flicker option To the maximum didn't change much ....

Found the problem

for the buzzing & the bar going up & down

I just unplug my TV CABLE wire & it stoped
to a cable wire can do an inteference that bad!.......

now image is like 99% perfecT

tHanks for you help anyways^_^

So you can use TV out or video in, but you have to keep connecting/disconnecting the cable coax?
That's annoying! Definitely a ground loop problem.

[hayabusa]

yeah I dunno whats making it....

I have 2 pc in the room...

im just passing the S-Video to Tv .. & it occured...

i unplugged my cable it stopped

I tryed some game emulator to try it out sometimes the start with a black screen so thats how i re tested it

& now it was fine....


but tonight i retryed it...
with an emulator i could of swore it was 99% okay yesterday but now theres a back on top only going up & down quite fast
sometimes it's in the bottom......
it's Really annoying
