Can't get a native resolution

kaxfenix · 01 May 2009

Running Build 7100

I have a nvida 7600GT using Driver version 8.15.11.8581

My monitor is a Acer AL1916w (19" wide)
It's native resolution is 1440x900

I am unable to achieve this, it seems W7 can not recognize my monitor and defaults it to a generic PNP Monitor. The cable is a VGA cable with a DVI adapter to my Video card. The cable is unfortunately built in so I can not swap it with a true DVI cable.

I have been unsuccessful in finding any type of driver that is compatiable. The Driver directly from Acer is xp and there is not exe so I can not run in a compatibility mode, as well as trying to up date it via device manager and pointing it to where the files are is unsuccessful ..

Any one have any fixes or work arounds ?

Thanks guys, my first post here, look forward to ebing apart of the community!

Run this and save the output. It will tell me what capabilities your monitor is reporting through your DVI adapter to the video card, and then to the video drivers and finally to Windows and the Screen Resolution control panel. Hardly any monitors are recognized by name in Windows Vista or 7. That's pretty much legacy feature for monitors that are not PnP. http://www.entechtaiwan.com/files/moninfo.exe

Baarod, thanks for the reply, how ever I am a neophyte with this program, I installed it and ran the executable, but all I am getting under Display IDs are samples. Behold

I am not sure if this is live info or if these are samples as it implies.. Further more I do not see any options to actually tell it to do something beyond saving the sample information .. Please advise, and thanks for your patients.

You need a new adapter. Your monitor has an EDID but your video card can't see it because your adapter won't pass that information through. I've never created an EDID from scratch -- all my work takes the incorrect information from the EDID that the manufacturer provides and modifies it to fix the resolutions and refresh rates (and even gives the monitor a real name in device manager!) What this is telling me is that neither Windows and the graphics hardware/driver OR Entech's direct access to DDC (Display Data Channel - Wikipedia, the free encyclopedia) can access the monitor's capability data.

You need a new adapter OR if you can provide me with all the info that's listed by MonInfo like this I can try to build you a new monitor driver from scratch:

Get as close as you can using the website, tech support and the manual and I'll just do what Acer's firmware engineers do -- translate the monitor capabilities into an EDID. Only I'll then use it to create a special kind of display driver that's normally used to override a BAD EDID not take the place of a missing one. It should work but I've never tested it...

Baarod,

Hey Baarod any luck ?

Sorry, I thought you weren't interested. I'll get to work on it using what I can from your monitor inf.

kaxfenix · 06 May 2009

I am definitely interested, and I am very thankful for your time

OK, well this was quite an adventure but I think now I have the tools, VESA specs and math down to the point where I can manufacture monitor drivers. I can't guarantee that this will work since you don't actually have an EDID to override but it should work (in theory). One thing you have that I need is your monitor's .ICM file. You need to put that in the same directory to which you unzip the attached .INF file. Also, I have no capacity to create signed driver catalog files at this point so you will be warned that this driver is not digitally signed. I don't really think we need to get Microsoft involved in this, do you?

So, without further ado, download this kaxfenix.zip, unzip it to a working directory, copy the .ICM file from your original monitor .INF package to that working directory, start device manager and update your monitor driver manually. It will never automatically choose an unsigned driver so you'll have to use the "have disk" method to directly select the new .INF file. Once it's installed, log off and back on again and try your new resolution. If it fails try rebooting -- whether that's required appears to be up to the video card and driver.

Let me know what happens please as I put about 20 hours of work into this!
