When I connect my 23-inch Samsung monitor with 2048 x 1152 resolution and 32
inch Vizio with 1920 x 1080 resolution to my Asus ATI Radeon graphics card, I
get side-by-side monitors that work fine. The only problem is the Samsung now
only gets 1920 x 1080. I connect the Samsung with a DVI cord and the Vizio with
an HDMI. Both to the same card. I have Windows 7 Home Premium. Is there any way
to run side-by-side and still have 2048 x 1152 on the Samsung? Would it take a
second graphics card?
In this excerpt from
Answercast #49, I look at a computer that is not displaying dual monitors
correctly. The setting should be right there in Screen Resolution.

The short answer is I’m not quite sure.
- If anything, it’s a limitation of the graphics card that you’re running
It may not necessarily take a second graphics card if that’s the case. It
may just take a different graphics card. But before you go down that road, I
want to investigate a couple of other options because I actually run this
I have a graphics card that has two outputs and I’m able to set those
different outputs to different resolutions if I want to. Windows 7 in
particular handles this very, very well.
The right thing to do is to right-click on the
Desktop, an empty area on the Desktop;
And go to Screen Resolution.
There, you will be able to see Windows’ concept of how your monitors are set
up. It will actually show you a graphical representation of two monitor images
next to each other.
If you click on one, you can then change the resolution on that monitor.
If you click on the other, you can change the resolution on that
Presumably, the graphics card is exposing the full capabilities of each of
the two different connections and Windows will allow you to select the most
appropriate resolution for that specific monitor – independent of what the
resolution is on the other monitor.
A new graphics card
Now, Windows supports this. So if for some reason that doesn’t happen (in
other words, both seem to be restricted to the lower of the two maximum
resolutions), then my only assumption can be that the graphics card itself is
incapable of driving two monitors at the same time at different
- There are absolutely graphics cards that can do that.
A second graphics card
Another approach, as you mentioned, is in fact a second graphics card.
- Windows will recognize that and it will drive both graphics cards just
So, like I said, try Windows; it may simply work for you if you know how
to get into the user interface to make it configure. If not, then one way or
another, it does seem to be a limitation of your graphics card and either adding
to it or replacing it are probably the most likely ways to resolve the

2 comments on “How do I get my two monitors to display at different maximum resolutions?”
Often craphics cards that can support multiple monitors state what resolutions they can support – I know that if I connect multiple monitors to my card, the maximum resolution for at least some of them will be lower than the maximum for a single monitor on it’s own.
After further study I found the solution. I had selected “Duplicate these Displays thinking I wanted the same icons and taskbar on each display. With this selection I got the lower resolution on each monitor. I switched to the “Extend these Displays” and now have the correct resolution for each monitor. Thank you for your help.
