hi everybody !
i'm so happy to having recieve my accell cable ( ultraAV display port to DVI-D )
bu I have a big problem with it !
i can't enter my resolution (1680*1050)

in the graphic control pannel i just look 1600*1200 or 1440*900 around this resolution...

and when try to use eyefinity, the resolution is not good and stretched...

do you have a solution for that ?

youhouuuuuuu !!
i found !
that's tips:

in catalst window go to gestion of monitors, do right clic on the bad monitor, properties..

a window appears with avvivo and HD parameters. in HD parameters activate 1080p 60Hz !

when you activate it, the correct resolution will appears in the windows 7 display configuration !

edit: but eyefinity doesn't work yet ...
arrrrgh !!!

the problem is not really solve, i have force the resolution when activate 1080p, but the image is "fade" (or melted, i don't know this word in english)
and i have try many test and at the end, the third screen refuse to work ! windows says he can't save my configuration, and ati drivers freeze and restart at the beginning when i try to activate my third screen...

i have doing system restauration and now i can re-activate my third screen but the bug with resolution is also here.

i'm waiting whql drivers from ati and i hope they will solve the problem...

i can't enter my resolution (1680*1050)

in HD parameters activate 1080p 60Hz !

Sounds like you have a mix of 16:10 and 16:9 monitors (or i misunderstood)

1680x1050 = 16:10
1600x1080 = 16:9

eyefinity only works with same resolution on all 3 screens.
what kind of monitors do you have?

i have only 16/10 monitors in 1680*1050. (three zalman trimon 22")

but in catalyst window i can activate a 1080p 60hz mode for hdtv. (by ticking a case)

but ticking this case don't force 1080p mode ! she juste allow me to setup this resolution in windows 7 resolution window. and between 1600*1200 and 1920*1080 there is ... 1680*1050 !!!

the resolution appears and i can select and apply her !!!

but with this method i can't activate eyefinity because it's a forced mode ! not a native mode... an activate eyefinity will appears 3 monitors in 1680*1050 in clone mode. i can't have one display with 5040*1050 and try to desactive eyefinity after that cause many bugs and black screens...

Try using the adapter in another one of the monitors. Maybe it's a monitor problem.

Sounds like your monitors support higher res than the native res (blame your scalers) . Eyefinity has been choosing the highest supported resolutions for the monitors (unfortunately) and a lot of people are having similar issues. There are a couple of ways to fix this:

1. Complain to ATI about the bad resolution selection.
2. Hack your monitors supported res. (this is an advance skill and is different for each monitor)

I do suggest option number 1 because we all would benefit.

i ran 3x acer v223w 22" 1680x1050 monitors at 5040x1050 no problem using the dell/bizlink adapter.

now running 3x asus 25.5 1920x1200 monitors, no prob.

What is the make and model of your monitors?

my trhee monitors are zalman trimon 22". (3d screens but they are simple monitors at 60hz. that's just driver which interlace the 3d graphics)

i have one monitor at the beguinning and i have bought another 2 for use with eyefinity and the accell converter.

so the two monitors at the right and left are brand new.
but i have also an hp w2207h with hdmi on another pc... i'll try to connect him on the adaptator with a hdmi to dvi passive converter and i'll see if the problem is the monitor...

for ATI, i have tryed ti send a return about my problem but it's really incrdible !
on there website, contact section make an error and don't work.
phone number in France is out
i just can send a bug report without any obligation of reponse or any certitude that my request will be understand...

so you have says i can hack the screen resolution... i'm searching that but now i haven't seen anything about that. (an hardware hack ! not for just one game !!! i have tryed that and the game crash)

now running 3x asus 25.5 1920x1200 monitors, no prob.

it's good to see that accell adaptor is functionnal ! :D
but i have seen on other french forum there is incompatible monitors with these types of adapters ... it's true or false ?
