Dual Monitor Setup

jshhndsd · Jan 11, 2017

Hi Guys,

Just had my PC installed with Windows 10. Everything works fine except that my dual screen monitors are mirroring each other which I don't want. The system also only detects one screen although there are two. The graphics card installed is a ATI Radeon HD 3450. Checked the Device Manager and apparently the display adapter registers it as ATI Radeon HD 3450. However the monitors are listed as Generic PnP Monitors. What does this mean? I also checked for updated drivers for the display adapter and it only accommodates OS's up till Windows 8 (64 bit.) Could this be the reason for the detection of one monitor instead of two? Would be very grateful for a solution.

Thanks in advance.

Are you actually using two video cables or just a spliter? Can you change the options in display settings to split the displays?

I am currently using a VGA splitter. This worked well with the same graphics card mentioned before upgrading to Windows 10 from Windows 7 on the same dual monitor setup.

A splitter would just cut the same signal into two, you can't show different images with a splitter. Do you maybe have a DB-59 adapter like this

Or something else? How are the monitors wired? Do you have anything in the drop-down options for how the screen configuration is? Post a screenshot of your display options if you can.

It may be a driver issue with Windows 10, I have seen dual monitors not work on a card on older drivers or wrong drivers, but you may just have the monitors hooked up the wrong way.

I actually have the exact same adapter like the one pictured. My apologies I assumed the splitter and adapter were the same. Which are then used to connect each monitor through their own indivual VGA cables.

This setup allowed me to extend the displays using Windows 7 before installing 10. The graphics card apparently only supports drivers up till Win 8 which drew me to the conclusion that that's what is preventing me from doing so in Win 10.

Yes you may be stuck with needing to upgrade the card or go with Windows 7 or 8. Splitter and "adapter" are often used as one and the same but are not really, especially when it comes to troubleshooting. Converter and adapter also, they all have differences when you say them to a tech person, or at least a good one LOL.

This is a splitter, it just takes the same signal and distributes it to several sources, all of them show the same thing.

Thank you for your assistance and clarification. This is very much appreciated. I had sent in a request for an NVIDIA GeForce GT 610. A compatible card with Win 10 for very basic office work.
