Here I would looking for something that works on some of the latest titles as well as other things besides games since I also tried running things at the 2880x900 resolution as well but with an ATI driven card.

Presently I'll be taking a look at the new Ultramon 3.0.7 beta software. Download UltraMon Beta

That immediately freed up some taskbar space on the primary display real fast now seeing the taskbar extended over to the second one!

Hello Balc0 Welcome to the Se7enforums!

The problem there is so fast and easy to correct you won't believe you missed it! First go into the Control Panel>Display to select the one of the three options seen there. Once you have one of the panels highlighted you simply choose from:
Extend desktop to this display,
Duplicate desktop on 1 and 2,
Duplicate desktop on 1 and 3(3rd monitor required).

From there you can use a program like DisplayFusion or Ultramon for stretching a single background or have a separate wallpaper on each. I run an ATI card here and had to that out here when first going to set a dual display!

That will still be useful to know at some point. When booting you'll notice one will see something come up on the screen just before the other as well as the post tests and initial startup. Once the desktop you then see the stretch across.

The Catalyst will now allow you to check off the "reduce the DVI frequency for high resolution displays" and/or the "Alternate DVI operational mode" options for each separately as well as adjust the image scaling. You can select which will be the #1 primary and #2 secondary display as well.

Windows 7 64 bit
Secondary display resoution


I can see lots of intelligent people on this forum and hope that you can help. I have an ATI Radeon 3600 running under Windows 7 64 bit. I have two LG Flatron W2252S displays attached. My problem is this: I get the option to choose the native 1680x1050 pixel resolution for one monitor, but not the other. Windows 7 seems to see one monitor as a plug'n'pray monitor, but the other shows as non p'n'p even though both are exactly the same. I get the option to choose the correct resolution for both when using Vista or XP (all of which are running on this machine). I have tried:

1) Downloading the LG driver for the monitor and manually updating the driver for both displays
2) Using the latest Catalyst software and trying all the tricks in there
3) Praying

None of the above has worked. If anyone has any ideas, I would appreciate something else to try. I hope that this isn't an early Win7 bug...

Thanks in advance for your input.

Hello dar69 Welcome to the Se7enforums!

Two things you try there making sure the second monitor is functioning as it should would be going through the setup option for the monitor itself and a trip into the Control Panel>Display section there for configuring the two LGs. You can elect to clone one onto the other or extend the primary onto the secondary display using the "Change Display Settings" option there.

The screen here will show how that looks when clicking on the link for that once in the Display section. Note the Display is the monitor either 1 for primary or 2 for secondary. Under that you set the default resolution dollowed by the orientation and then onto the multiple displays setting for duplication on 1+2, 1+3 if a 3rd monitor is present, and the preferred Extend desktop to this diplay option.

Thanks for the reply!

Sadly it didn't help, but I seem to have found a solution. For some reason the EDID information for the second screen was showing a maximum resolution and refresh rate that were different to that of the first screen. When I override the EDID and make the maximum resolution and refresh rate the same as the first monitor, I get the option to select the 1680 x 1050 resolution! How very strange and extremely annoying!

Thanks for your efforts to help. I hope that posting this here will save someone else the two days of messing around it's taken me to fix the problem.

I'm sure it will especially for that brand of monitor. While many probably would only need a quick trip into the Control Panel to make the setting changes there this should be a help for those who run into similar if not the same with mulimonitor setups at first. Glad to hear you have that sorted out there!

I don't want to use my second monitor as a second "windows screen", I want both monitors to be used as one.

I don't want a clone, but I want to see the task bar go from the left side of the left screen to the right side of the right screen

Now I have windows extend on the second screen.


You'll have to use a third party up to extend it, search the forum, there's two being developed currently.
The Intel Video driver with my very humble laptop works fine like this -- choose extend desktop then you've got One desktop - depending on how you configure it it works either way round (L ==>R or R==>L) .

With different Video cards you should get similar options for dual monitors - depending on the capacity of the video card however you might not be able to get FULL resolution on ALL the monitors - especially if you want to try with 4.

Extended desktops is probably an option on all decent video cards these days.
