Windows 7: 2nd Monitor Decides when to turn on Radeon HD 2400 PRO

2nd Monitor Decides when to turn on Radeon HD 2400 PRO

Hey I have a slight problem and was wondering if anyone here has had a similar issue...

I am running a dual display with two Acer AL1916W Monitors using a DVI to 2 VGA splitter (y-type)... it worked flawlessly the first few months but now it doesnt. The 2nd monitor will not "boot" and stays in "input not supported" for about 10-30 minutes then will activate at random and function properly...until I turn off the computer.

Running:

Core 2 Duo 2.33ghz
4 GB RAM
Windows 7 64 Pro SP1
Radeon HD 2400 Pro (latest drivers installed)

Note.. The only available drivers I could find for the monitors were for 32bit XP...
Windows sees them as "Generic PnP Monitor"... not sure if another driver would work...

Thanks!

Give this one a try,

AL1916wc.zip

used it without issue when I used to have the same monitor. Also,

if I may ask why? Connected like that all you get is the same thing on both. Be better to connect one via DVI and one via VGA so you can then set them to extended mode, and use each monitor independently.

The dell inspiron I have only has a DVI port :/ and it actually came with the splitter... so I've been using it. There is a VGA port on the back but its covered with a black plastic "NO" sign. Trying the driver now thanks!
