HP P6-2133W will randomly lose its resolution after rebooting.

[APG73]

I think I know what the problem is...

To check the issue, do this: 

Boot the PC with the monitor connected with the DVI cable.  If PC boots into the low -resolution mode, remove the DVI cable from the back of the PC, unplug the power to the monitor and wait 10 seconds.  Now plug power back into the monitor and then plug the DVI cable back into the back of the PC. 

Is the resolution normal now?

PS- if you do this in any other order or remove the wrong end of the cable the test is not valid. 

As another secondary (separate test) - if you connect the monitor to the PC via VGA (instead of DVI) this should also work. 

Let me know if the results of your test(s) and I can assist you further. 

I am an HP enmployee but this is my own opinion.

Thank you. If the resolution goes back to its 1920x1080 then what does that tell me? Is it the monitor? Is it the computer? I havent tried it yet but I will when I get home.

Hi,

Contact HP Support.  There are known issues with some PCs starting up with DVI. It's also possible that it is a monitor incompatibility issues with your PC.

HP's support number is 800-474-6836 or 800-HPINVENT or online here.

If the resolution goes back to normal then the issue is with the PC, read and follow this document. 

Your Motherboard does not have a VGA connection so don't worry about that part.  It is not critical.

Though I am an HP employee, this is just my opinion. 

Good luck.

"Sigh." What does this mean for me? Its not like there going to replace the motherboard with a different one and give me a different graphics unit...

Hi,

If you had a discrete video card then HP might just replace the card.

[ForeverSupra]

It isnt discrete... Its an APU, built in integrated video/processor. Part of the motherboard...

[Big_Dave]

Hi,

Yes I know that you don't have a discrete video card.  That's why I said " If you had" in the above post.

Contact HP Support.

[ForeverSupra]

Well? That doesnt help much. Thanks anyways.

When you get home, conduct the quick test as described in my earlier post.  If the resolution returns to normal, follow the document link in my second post. 

If the resolution doesn't work (I'll be surprised) we will figure it out.
