Hello, I'm having an issue using two monitors on my PC. A bit of background info: Ive been using dual monitors for about a year by plugging one into my on-board GPU (VGA-VGA) and one into my external GPU (VGA-VGA-DVI-I using an adapter). For reasons which I can't be bothered to explain because it's not important, my on-board GPU no longer works and I must use my two DVI-I ports on my GPU. Now, here's the problem: Both screens are identical, with VGA-VGA wires. I am using an official ATI VGA-DVI-I adapter that came with my GPU (NVIDIA GeForce 9600GT) to connect the one screen. However, I purchased a cheap £1.50 VGA-DVI-I adapter off eBay for the second screen. But my problem is that when I connect either screen with the eBay adapter, it doesn't work properly. Here's a bit of elaboration: I can connect EITHER screen in EITHER of my GPU ports using the official ATI adapter, and they work fine. However, when I connect EITHER screen in EITHER of my GPU ports using the eBay-bought adapter, it either doesn't detect any screen, or it caps me at 1024x786 resolution. When I go to change my resolution, it calls the not-working one "Generic non-pnp" where-as my working one is called Packard Bell 200Ws. This leads me to believe that there is an issue with my eBay bought adapter, I just wanted someone to clarify that this is the issue? I don't want to pay the prices that places like PC World charge for a good adapter, so I want to check here first that the adapter is the issue. What would you advise? Also, the adapter is 24+5 pins DVI-I MALE to 15 pins VGA FEMALE. Thanks in advance, Gee. EDIT: Is it possible that my GPU can't run two screens at 1600x900? The GPU is PCI-E connected, NVIDIA GeForce 9600GT 512Mb.
