Forums -> Multiple monitors -> 2 Monitors and 1 tv on HD4870
Jimmy Ch.   2010-06-24 08:56
I have gotten hold of a Radeon HD4870 (1 Gb, 2 x HDMI + 1 x S-Video) and I wan’t to know if there is any way I can connect my 2 BenQ T221WA monitors and my TV at the same time, under Windows 7 or by using Ultramon or the likes? I can live with a multiple display profile setup, where either the 2 monitors or one monitor and the TV is “active” and I can switch between the profiles without plugging/unplugging cables and restarting and so on..
Of course I would prefer both monitors and the TV utilized at once, but I can live with the aforementioned setup. Does anyone have any experiences with this combination?

Most likely the card only supports two monitors at a time, but you can still connect all 3 and then switch between 2 monitors or 1 monitor + TV via Windows Display Properties.

UltraMon display profiles currently don't support this, but you'll be able to do this with the next release, 3.1.0.

Are there any preliminary releasedate for 3.1.0?

Not yet, it's still under development.

Ok I have 3.1 and I'm thinking I'm doing something wrong.

I have 3 outputs on video card (vga, dvi, hdmi). I had a monitor connected to vga and a 2nd monitor connected to the dvi. I then saved that profile (just clicked ok on everything).

I then connected a tv to the hdmi and rebooted, win xp/ultramon recognized the tv and I configured it to use 1 monitor and the tv. I then saved that profile.

I then clicked on the first profile thinking that would shut off the tv and start the monitor in its place. Nothing happened.

Am I missing something?

I guess the video card can only drive two monitors at a time? In that case you would need to switch between TV and monitor via the software for the video card, UltraMon can only do this on Windows 7 unfortunately.

Yep, like most video cards mine has 3 outputs (dvi, hdmi, vga) but you can only use 2 at a time.

I am using xp. I would seriously consider upgrading to win 7 thou to get this capability.

So just to confirm, others are using video cards like mine and turning monitors off/on via ultramon?

I have such a setup myself with an ATI card, works fine with UltraMon 3.1.0. The reason this is only supported on Windows 7 is that a new API was introduced for configuring this, on previous versions of Windows this was video card-specific.

Darn, just checked to see if I could upgrade my xp to win 7. Really can't as it needs to be a new install. Might not be a bad thing, now I'm looking at I7 processor with 16 gbs memory!
