HP nx7400 with docking station and wide LCD problem

by pierrot.robert / June 6, 2007 10:49 PM PDT


I just bought a HP nx7400 laptop (EN352UT) with a docking station (EN488AA). I use Windows XP SP2 and all the latest drivers from HP web site are applied.

My monitor is an Acer AL1916W, with a native resolution of 1440X900.

The problem is that when I use the external display, connected to the docking station, about half an inch of the screen is missing to the right hand side. If I use a program in full screen I cannot see the right scroll bar. I do not see Windows clock either.

Any tips or suggestions ?

Thank you.

Just an old fashioned windows issue.

Nothing busted I fear. It's one of those Windows annoyances that we have to tell Windows the monitor capabilities. There are more than a few ways but I'll share what I do.

1. Find and offer windows the MONITOR.INF for the new monitor so it knows about it's "skills." After that head to display properties to set not only the screen size (pixels) but pick what monitor to use.

2. If you couldn't do item 1, try setting the video screen pixels manually and try other refresh rates.

Remember this is not a bug but an annoyance. Nothing busted but something we all wish would just work without out help.

I think this does not apply to my case.

The display IS set to 1440X900, so XP "knows" that my monitor is capable. And I can't try another refresh rate as it is a LCD, not CRT.

I run into this far too often. Let me be clearer.

Did you use the MONITOR.INF file from that monitor's maker?

Yes or no? If no, go do that.

I did install the MONITOR.INF for the AL1916W and it did not change anything.

After that we choose that monitor in ...

Display Properties, here's the screen I usually check to make sure the monitor is selected.

If we could see yours (screenshot at that would be nice.

This area is still annoying and we all wish we didn't have to check it over.

Click that properties button to select your new monitor if it's not on that panel.

I opened a case with HP tech support and a still unreleased BIOS update solved it.

Thank you.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
