Post subject:  Problems running tree monitors.
So, I was hoping that anyone could help me with this little conundrum that I'm having.

I have a ATI HD4670 for a laptop.
Yeah, I know, but I'd like to test it out if it can work, because that would be so cool:D

There are several outports from the laptop

VGA
Display
HDMI

and I am using the HDMI to connect a 24" screen.
I can use the HDMI with either the laptop screen or anything connected to the VGA(extra screen or projector),
but I can't use all three at the same time, and I haven't been able to test the Display port anyways.
Is there a workaround for this? Or do I just have to get myself a new computer?

Acer Aspire 8935G
Intel Core2 Duo P7550 @ 2.26Ghz 2.27Ghz (Don't know why it's two of those, but that's what the windows raiting said. Also, I'd like to overclock this CPU just a littlebit if anyone can help me with that;))
4 GB Ram
ATI Radeon HD4670 1 GB Ram

Hoping this will be sufficient to run three monitors.
And thanks for all the help I can get;)

So this is kinda what I've found out.
This site was slow, so I got a email telling me it's not possible with 3x screens on just the hardware I have.

Also, ATI is asses because they removed their option to "Horizontally Span Across" for using two screens. So this sucks too.
If anyone finds out a way to hook up two screens as one on a ATI HD4670, please, do share.

If you're talking about eyefinity, no, this isn't possible on anything lower than a 5xxx series card. If you're simply talking about running multiple monitors, I believe two is the limit on your laptop, so your laptop screen plus 1.

No, without a DisplayPort connection you are limited to having 2 Screens at one time.

I also don't know what you're talking about when you say that ATI has removed the option to "span across two screens." ATI have ALWAYS allowed 2 screens to be active at one time and, I think, what you're wanting is the "EXTEND" mode...which works just fine.

As for the "span across two screens" I have NEVER seen that option and I've been using ATI cards exclusively since 1996 or slightly before.

EDIT: A little research turned up this information: Horizontal Span was removed by MICROSOFT due to the new driver requirements since Vista. There "may" have been a rudimentary way to get around it but, the absence is due to Microsoft...not ATI.

You might want to check out UltraMon to see if that works for you. Google is your friend.

The ability to horizontally span was removed in Windows vista, has nothing to do with ATI.

Did you even bother reading my own response immediately above yours? Check out the EDIT comment. :twisted:
