No sound Visually the monitor works fine but there is no sound. OS is XP and originaly had an old monitor attached. Have just upgraded to this flat screen.

Upgrades are usually troublesome as they leave bits of the old OS in odd places. It is best to do a clean install.
Choose your OS, either Vista or Win7. XP will not work!
Always download the latest drivers for the OS you are using from hp.com or it will keep hanging and be unreliable.
Hope this helps.

obsolete PC, HP has zero support on it
no OS, stated, XP? what XP - service pack 3?
no service tag presented.

sounds like mobo is e-machine, onboard video chip bad,.
yes, most mobo support an old VGA card not sold now.
only used, and must match your machines express card,
voltages, etc. called express level #
the must go to bios and change from internal video to external.
that part is tricky on dead screen. no?
find that card (old) and working used, is problematic, could take weeks to find one... why?

and old old Pentium 4 wow.
why no scrap the best and upgrade to a newer system.
one with SUPPORT?
10 years or newer,
can be had used for like $50 (the brick, no screen)
why mess with OLD IRON like this... time to move on.
no?
why spend a fortune on a PC worth $5 on the street
why?
ever go to GOODWILL>? see vast machines far newer, for NOTHING?
or here, amazing no?
and this, even new boxes are cheap.
H3LL less than one service charge at a shop. Geek something.

That sounds like a display/resolution setting problem on your PC. I doubt there is anything actually wrong with the PC or the monitor, since both work with different combinations, so its most likely just a setting.

Some monitors don't display anything when they get a signal/resolution that is not compatible with their displays. I would try changing the display settings on your computer with your old monitor, then switch monitors and see if your newer monitor works.

Here's how to adjust the display resolution:
If in XP, right-click on the desktop and go to Properties, and select the tab for display settings and adjust/lower the resolution. If in Vista/Win7 right-click the desktop and select Screen Resolution/Display Settings and adjust it there.

An Accer monitor will work on most any computer, even a laptop. (plugged into the rear extension port). Weither XP, Vista, or Win98 doesn't matter.

Please try to check it from Control Panel > Sound, speech & audio devices > Sound and Audio Devices > Hardware tab > then select the Device Name then click Properties tab to verify its condition status or you opt to click Troubleshoot tab. regards

THANKS

Hey ya'll.
I had the same problem with everything installed,icons on the screen etc...I took my stuff to my computer wizard and he came with the following solution which is:
Make sure that you have a Windows XP "SP2 or GREATER" this is the kicker.Go to the requirements sheet if you need more info.
Anyway I did that upgrade from SP1 to SP2 and it works like a charm with pristine sound.
Good luck fellows.

I would go to http://support.gateway.com/support/default.aspx input your model and os then dload and install drivers for the motherboard.This should fix the problem.

Hi,

It sometimes takes up a minute for video card to detect new moitor. Try attaching new monitor only and boot it in save mode.

Most like the sound card you have is not compatible with Windows Vista. You need to check the manufacturers website to see if there is any patch for Windows Vista
