ATI / Windows 7 Detects False Monitor

[TheOriginalTO]

I have Windows 7 Home 64 bit installed on an ASUS G73JH With an ATI Mobility Radeon HD 5870. My problem... Whenever I start the monitor up, whether it be turn the laptop on, or just wake it from sleep it detects a false non-generic pnp monitor. I do not have any extra monitors, it is just my laptop. Can anyone help me find a solution to getting this fixed please?

Bump. Any help?

Apparently no one knows?

Hi

Welcome to Seven Forums
Have you tried updating your card drivers? And the chipset drivers?

Keep us posted and regards

All of those problems are ones i do not have. Also my drivers and chipset are all up to date. So... idk what else to do.

I had an experience with this on an ATI HD 2xxx series card a while back. I don't know how it appeared, but the only way I "solved" it was to open CCC and disable the phantom monitor. To the best of my recollection, it did not reappear after disabling it in CCC.

Well, it keeps showing up even after I disable it in the CCC. this is making me sad

When you click on the picture of the monitor and select Properties in CCC, what info does it give you about the phantom monitor?

EDIT: Just thought of something... Have you by chance hooked this pc to a television? I remember having a "remnant" monitor in CCC after hooking my pc (the one with the ATI HD 2xxx card) to a television once. I had connected it via the S-Vid out on the card. And again, to repeat myself, to the best of my recollection, I removed it by disabling it.

Doesn't sound like this is too much help, though.

I'll post back if I remember something or if I can recreate it (it was in Vista, though)

I'll get back to you with the properties info. when I re-create it. No, My laptop has never been connected to any other display device. Thank you for your help. I'll see what else I can do as well.

Update: Started my laptop this morning and not only was my resolution messed up, but it changed my desktop picture too. As soon as I disabled the phantom monitor all went back to normal, but I fear this will happen again. Edit: Whenever I hit detect displays in the CCC it gets rid of it.

Properties info: It is an exact copy of my monitor for my laptop ( Generic PNP )

Device type: Monitors
Manufacturer: ( standard monitor types )
Location: On ATI Mobility Radeon HD 5800 Series

Generic Non-PnP Monitor
Driver provider: Microsoft
Driver Date: 6/21/2006 ( I tried updating, no success )
Driver version: 6.1.7600.16385
Digital Signer: Microsoft Windows

Thanks again guys.

Hi

In CCC, could you try disabling Catalyst A.I?
Open CCC > Graphics > 3D> Tick (or check) Disable Catalyst A.I.

What does this do?? Will I see any differences with it off?

I often find that when a computer thinks it has more than one monitor, it is because of a conflict in drivers. Have you tried completely removing all video drivers?

My problem was that I had a bad installation of a second set of drivers I didn't even know about. When I wiped them all, and then installed the fresh drivers, my problem was solved.

Also, welcome to the boards! I hope this gets resolved and you can use the forum for idea's instead of just troubleshooting, it really is a great place!

So far I did a clean install of the 10.8 drivers and everything seems to be fine. Hopefully it is done being dumb. but thanks to everyone for everything. I hope it stays like how it is now.

 

[TheOriginalTO]

So far no problems. IDK what magically did that I have not tried more than 5 times.... but it is now cool again. Thanks for your help guys.

 

[Lomai]

Thanks for letting us know

Take care and regards

And it is back again Nothing has changed. It was working for a few days and just started yet again. I really am getting bored of this.

Let's see if getting rid of the phantom/false monitor in Device Manager fixes it. Start with setting Device Manager to show hidden devices,

Then when you get to step #3 click on Monitors and uninstall any that are grayed out. Hopefully that will get Windows to stop "seeing" the phantom monitor.

It did not show up as a hidden device. As soon as I hit detect monitors i vanishes not only from CCC, But from device manager as well. Thanks for trying
