Multiple Displays, Multiple Resolutions

[charlie3]

I have a desktop set up with 2 displays, at the moment they are next to each other and i have an extended desktop.

I now want to clone or Duplicate these displays, i can do this but the resolutions have to be the same. One Display is 1600*1024 and the other is 1920*1080.

Is there any way i can have the same image on both screens, but with different resolutions? any third party software??

Hello Charlie,

It shouldn't matter what the screen resolutions are on each monitor. I have one at 1920x1200 and one at 1280x1024 that I set to Duplicate these displays.



Hope this helps,
Shawn

sorry to dig up this old thread but what you suggested doesn't work for me? if i select duplicate displays they both have to be the same resolution?

once duplicated both screens are operating at well below their native resolution.

one display is connected to an hdmi port and the other to a vga port

does anyone know anything about this sort of stuff?

Something to try if you haven't done this. Install or update the drivers for both monitors.

Some info please:

One is HDMI, one is VGA, are both connected to the Graphics card?
What Graphics card do you have?
Have you tried DVI instead of VGA? or is DVI not available?

The resolution is dropping to a safe resolution that both monitors can work with. Have you tried adjusting the resolution for each monitor after setting them to duplicate?

my computer is not all that good. all the stuff is integrated and i only have hdmi and vga out, there are no other options.

says i have a ati radeon 3200? mean anything, i think i have integrated graphics

once displays are duplicated i can only change settings for both of them. see picture

 

[Thorsen]

yep the ati radeon 3200 is integrated graphics Notebookcheck: ATI Radeon HD 3200

Do you have to Catalyst Control Center on you computer? it should be at top of list whe right-clicking on desktop. You might be able to change it in there

AMD M780G Specifications

ATI SurroundView™ Technology
Provides support for four or more monitors when you combine an integrated graphics processor (AMD 780 chipset-based motherboard) with a discrete graphics processor (ATI Radeon™ HD 2400 Series2 or ATI Radeon™ HD 3000 Series). Each additional discrete graphics processor can provide support for two or more independent monitors. The integrated graphics processor and the discrete graphics processor work in parallel to drive multiple displays.


I think this chipset doesn't provide support for multiple monitors until a dedicated graphics card is added.

no i can get multiple monitors i have setup an extended and cloned desktops but its just the resolution that is the problem. yes i have tried changeing it from the ccc, same problem.

Maybe when the ATI Radeon 3200 detects multiple monitors it drops the max resolution of both devices to something that it can manage? A memory limitation perhaps?

 

[charlie3]

4gb of ram, will that be enough?

 

[charlie3]

or do you mean video memory?

 

[Thorsen]

There is a place in the BIOS usually in Advanced>Integrated Chipset that allows you to select how much RAM the Integrated Graphics uses. It is probably set to 1G based on the Specs you listed for your computer. you might be able to increase it to see if that allows the graphics chip to use more and thus allow a higher screen resolution.

Note: the Graphics Chip shares RAM with the total you have on your comp so if you have 4G of Ram and you set the graphics to use 2G then you will only have 2G left.

Edit: Be very careful with BIOS settings and if you are worried about something or if something looks different than I described, post here first for help

 

[charlie3]

so look for integrated chipset to make more video memory available?

once i have done this i cant see how the windows resolution options will change to allow me to change the resolutions of each display.

will have a look in the bios.

[not so gray matter]

It's the graphics card's memory, not your system wide memory. You need to upgrade to a better gfx card if you want to run dual monitors without them being mirrored. If you don't want to break the bank, an ATI Radeon 4000 series or a GeForce 9000 series should do the trick.

I'm currently running a 9600 GT and it can handle an extended display of two monitors just fine.

i have set up an extended desktop in the past, and used different resolutions on both of them.

but i need to duplicate the displays and have the same resolution.

this is what my bios looks like, any idea on what to change to make more video memory available?

 

[Thorsen]

I would also suggest getting a dedicated graphics card. All BIOS's are different and your BIOS might not have the ability to change how much RAM your card uses.

 

[charlie3]

right i will look into getting a cheap graphics card, any recommendations?
