Tearing using VGA outputs for live shows

[manuel]

Hi guys, i've been reading all the threads I can about this problem, and in other gaming forums. The thing is i'm not a gamer, I use Eyefinity for media servers in live shows, And the standard here in argentina is to use VGA signal, not DVI. I saw a lot of "solutions" for the tearing problem that is using DVI signal instead of VGA.


5770 cards didn't have this problem

I couldn't fix the problem on a xfx 6850.

Tried all the configurations possible, a lot of beta drivers, but no.

Now im looking to buy a 7850 card, but if the tearing on VGA signal has no fix, it's not going to help me.

any idea ?

Tearing while using all VGA is mostly unheard of around these parts, as you say most people suffer from DVI tearing/flickering.
It the card OC'ed or is AMD overdrive enabled, sometimes this could cause this issue.
Could it be a bad adaptor, is it on the same monitor each time? if yes, if you move the displayport to vga dongle to another monitor, does the flickering/tearing follow the dongle?

Thanks for the welcome,

I don't have the 6850 right now to try it, but the miniDP adaptors i used werent the worse available.

I have a big projection mapping oct 15 and I will use two 6850 with 5 outputs to the projectors, so then i will make more tests.

any known problem for the 7850 to be aware of? mostly using VGA signal..

thanks again

I did not experience to many issues on my 5870E6 cards, and I am not experiencing any issues with my 7970, however thay are all dvi, apart from the 4th which is vga, still, no issues experienced here.

Hey guys, thanks for the help

the event went flawless. finally i did not set up any eyefinity group, just manage the outputs individually
