I recently got a new rig with a Geforce GTX 650 Ti it has 1 VGA port, a DVI-D port and a HDMI port. I have 2 monitors they are Hanns.G HL229DPB's they both have VGA ports, but 1 has a DVI-D port and one has a DVI-I port.

I got one monitor working with a VGA-VGA cable and it works perfectly, but when I use a DVI-D to DVI-D cable with either of my monitors (DVI-D and DVI-I) with the port on my graphics card (DVI-D) the monitor does now show up on anything, not on Device Manager, not when a press detect on Screen resolutions.

All drivers are up to date, it just can not find my second monitor, any suggestions?

DVI-D won't work. It's D, or digital. Won't work with VGA. The DVI-I port should work. (Integrated, or Digial and Analog together.) If you have a straight DVI-D cable it only has the digital pins, so that might be your issue. Find one with the Analog pins in there as well. Check the DVI wiki if you need help knowing which pins are which.

I am still having problems getting my monitor to work, I have tried a DVI-I cable with a DVI-D to DVI-I adapter in the back of my computer, i tried 2 DVI-D cables and my computer still cannot detect my monitor.

DVI-D is digital. As in Digital only. You can't connect a VGA (analog) cord/adapter to a DVI-D port. It won't work. The DVI to VGA adapters work ONLY in DVI-I ports. This wasn't an issue awhile ago as nearly all DVI ports on cards were DVI-I. But most now ship with DVI-D ports, or only one DVI-I port. If you've used yours up on your first monitor, you can't hook up a second analog monitor.

I do have a monitor that has a DVI-D port, which should be compatible? But using DVI-D cables with that monitor does not work either.

I am sorry if I am repeating and/or inexperienced, I mostly stick to software, it all is a bit confusing.

I looked up the stats on your HL229DPB monitor here and the monitor is purely an analog. It has VGA (aka D-SUB) and DVI-I.

Your video card only supports one analog monitor (not two). This means if you plan on using the two HL229DPB's you will need to buy an "active" converted (not just a cable it has to actually do signal conversion) from analog to digital.

You stated you also have a DVI-D monitor laying around. You did not name the model of this monitor so I am taking it on faith that it actually takes a digital signal. Let's call this monitor "digimon" for funsies. You should be able to hook up one of your HL229DPB monitors to vga and then your digimon to the DVI-D so long as you are using a DVI-D cable and both should work appropriately.

If it does not, test out both monitors independently would be my suggestion. I would also verify again that you are sure "digimon" is not an analog monitor.

I have got my monitors to work.

All i did was uninstall all my nvidia drivers, do a reboot, run a registry cleaner and install latest drivers. Do another reboot and that did it!
Thanks for you're suggestions.
