I have three ASUS 23" monitors, hooked up in an Eyefinity setup on an XFX Double D HD 7870.



My left monitor is plugged into the lower DVI, my middle monitor in the upper DVI, and my right monitor into the left miniDP via an active miniDP->DVI adapter.

However, when booting my PC, my left and right monitors show the POST screen and the Windows 7 boot screen, but only the left shows the logon screen, and the middle doesn't show anything at all until I have logged on. I have two profiles set up through CCC, one with three separate desktops set to extend, each one at 1920x1080, and one with them as a single 5760x1080 DisplayGroup. I usually leave it in extend mode unless I'm gaming, and then I switch it to Eyefinity via a hotkey. If I reboot while having it set in Eyefinity, it will show the POST/boot screen on the same monitors as before, but the logon screen on the middle monitor, with some overhang. It looks like it may be about 2160x1080 or so. I can furbish screenshots/pictures if it would be easier to tell what I mean.

Can anyone explain why my middle monitor doesn't even turn on until I login to windows? And on a side note, has anyone had any luck getting the logon screen to span across an Eyefinity setup?

Jup, same here.

AFAIK UEFI only supports 2 Screens! and not even in Extended mode but in mirrored.

i didn't realy pay attention to which screen is active when ^^ but for the W7 loggin screen. When i have Bezel corrected 6048*1080 and get to logon screen, i see main screen, and Left/Right Screen is black except a 2cm blue Bar (from top to botton) so its Width Resolution divided by count of Monitors :) but they didn't expect bezel corection!

This is exactly what i get except not bezel corrected. Also, they are mirrored, not extended. I forgot to say that earlier :P I'm interested mostly in trying to expand the boot/logon process onto all screens if that is possible at all. If it matters, my mobo is an MSI 990FXA-GD80, with ClickBIOS.

Nearly impossible! The only way would be via BIOS update. But IIRC Bios doesnt have VGA drivers, well sure they do. But just verry minimal. So no Features you have on Windows will work.
Though i'm not sure how Bios/uefi communicates with the gpu, i assume there is some predefined 2D modus on every GPU that works when on power. And it works exactly same on all GPU's. Maybe?

So the only thing you could achive would be a TripleMonitor Window Login screen.

Agree, this is almost impossible unfortunately. It used to drive me crazy when overclocking which is why I moved to Nvidia Surround.

So does it work with Surround?

So... any idea of how to accomplish that?

I've done my google'ing and come up short. I can deal with the booting funky, but logon would be cool in Eyefinity. :)

On AMD Eyefinity, for me the BIOS would be duplicated on 2 displays which drove me crazy while overclocking, I would end up turning a monitor off. With Nvidia Surround, it is simply displayed on one monitor. Same for the Triplehead2go. No setup that I am aware of displays a BIOS across three screens.

Can/have you connected two monitors to the two DVI ports and the third one to the HDMI port?

No, thats not supposed to work! Its a XFX and not a Sapphire Flex!

I don't feel like it... I haven't tried that a) because I'd have to get an HDMI cable or b) an HDMI -> DVI adapter which, yknow... too lazy.
