Display adapter for my hp laptop. i have two but only need one?

I'm having sound and video issues. i have discovered that i have two identical devices under my display adapter. they are only different in their resource information. the help and support says to check my "hardware documentation" to find the recommended setting so that i know which one to uninstall. i have NO idea how to figure that out. how do i know which one is the right one? i need to uninstall one i'm pretty sure. at the moment they are both enabled. i've tried disabling one and nothing happened. i disabled the other and then the size of the icons got larger and it was less defined so enabled them both back again. anyone??

Hi there. The reason you have 2 identical devices under your display adapter, is because you have an external monitor port (VGA) on the side. The more monitor/tv ports you have, the more devices you have under the display adapter.

I have an Acer Aspire laptop, which has an external VGA port, and a DVI port. So therefore, I have 3 devices under my display adapter.

Have you also tried updating to the latest service pack for your operating system?

There is nothing wrong in having two display adapter in device manager. This laptop has a LCD display on the laptop and also supports external monitor. So that you can configure dual monitors. To find what is wrong with sound, use a headphone and connect to the headphone jack of the laptop. If the sound is clear on the headphone, then the internal speakers of the laptop has gone bad. Since you said that windows start up sound it self is distorted, the possibility is like you may have lot of programs loading on startup. Click start->run and type 'msconfig' and press enter. In system configuration utility under general tab select 'selective startup' and uncheck 'load startup items'. click apply and close. It will ask you to restart the computer. Click restart. After reboot check for any sound distortion.

Revert back for clarifications...

My screen is black and wont power off

replace the cable that goes from your monitor to PC. Especially if you have a powered mini display adapter cable (if you have a video card that supports multiple monitors you will have a mini display powered adapter cable ) these power adapters burn out easily. 2 of mine were defective out of the box, I discovered defect by pure miracle.

The power supply for my Princeton Monitor, Model VL1916, S/N WCCE4307992 has gone bad. How do I get a replacement?

THe AC adapter (power supply) for my Princeton VL173 went bad. I discovered it was the PS and not the display by plugging in an old adapter from an HP printer that I had replaced. The input plugs matched and the power out profiles were nearly identical Only very minor differences). It was just a stab in the dark, but it works! Now my display is 12 years old and still going strong. I hope this helps.

I have an old Princeton VL 173 that I had been using with an old computer running Windows XP Pro. It works fine. Got a computer with an Asus MB and a Intel Core 2 Quad running Windows 7 Home Premium...

It sounds like a driver/software issue. When you ran the Princeton VL173 on XP you probably had all the correct software for your video card and the correct drivers to support your video output. When you changes OS to Windows 7, the XP drivers are no longer in place. My best guess is that you need to find and install the correct drivers for your system video and for your video card that are Windows 7 compatible. The old XP drivers will not work in Windows 7.

I am running XP with a Princeton VL173. It works great. I identified the correct video drivers for my system and installed them. My video card is nVidia 8800GT. I downloaded and installed the latest software from nVidia and installed it. It runs like a champ.

Several months ago my display died. It was just blank -- black. I tried using a power supply (AC adapter) from an old HP printer that died, and it worked! The plugs were identical, and the power output profiles were very nearly identical. It has been rinnung great for many months now.

I hope this helps.

No display

This issue could be with the video card that is integrated on the motherboard.
However, to isolate the issue with software or hardware please follow the steps below :

1. Disconnect the ac adapter and remove the battery from the laptop
2. press and hold the power button for 30 seconds
3. replace the battery and connect the ac adapter
4, turn on the laptop and check

if the issue persists then remove and replace the memory modules and check for the issue.

If the issue still persists then it could be a hardware issue and your laptop needs to be serviced.

Laptop isn't connecting to video controller?!

First, you have to know if there's a missing device driver (sound, display, etc)from your laptop to view all of them: from your desktop (using Windows XP) right click on My Computer icon choose Properties, Go to Hardware tab click Device Manager, you'll find a ( ? ) mark for the missing device, the solution is to install your Display Adapter driver if you are looking for a video controller, so you should have your CD driver for your laptop. in HP Laptops you can download drivers from, from Dell Laptops,

System not starting

If possible, try to plug an external monitor to the laptop and see if it displays anything. That will indicate a video problem on your laptop.
