"input not supported"

anon posts. you meant x768 im sure.
no PC stated, ? why?
windows 8, from HP? or from Microsoft???
is it on DVD? or on a stick this install medium?
where did you get w8 and from whom.?/? (matters)

that message is from w8 installer, (win8PE engine)
and is warning you this old monitor , can not do modern high resolutions. (or is not recognized ,IMO PE Failed you.)
there are 2 solutions,
if PC is HP, you never said what it is?
go to HP.com and get the w8 install media from them.
if not HP
go to unstated makers pc home page, do same.
if PC is so old its not supported by your PC maker go to.
not telling PC full name and model makes all help near impossible.
Lets play game, PC is so old W8 cant suport it now.
(learn that not all old hardware is supported now, a FACT)

ok got microsoft.com
and get the correct and current ISO install from them.
so it works right.

spec on your screen is
1366 x 768 @ 60Hz, 1280 x 1024 @ 60Hz, 1280 x 720 @ 60Hz, 1024 x 768 @ 60Hz, 800 x 600 @
60Hz, 720 x 400 @ 70Hz, 640 x 480 @ 60Hz

my guess is your w8 disk is old. and fails to know
the above. or fails to ID scan the HP1911 correctly
the screen can be 2011 screen , 6 years old.
means should not fail to install. ok.

yes it will but u need to adjust it to 1024x 768 60 hertz in settings menu ok

Sounds like the beeping is the least of the problems. "slightly melted around the AC jack" would be a main concern. You may have a fire hazard in your hands.

If all of the pins on your VGA cord are OK then it is quite possible that your graphics card is the real issue. If you don't have an aftermarket graphics card then its your on-board one, which is built onto your motherboard, if that is the case you have get a new motherboard. Be sure to back up all of your info because if you upgrade to a better MB then you have to do a clean install. On the other hand if you buy the same one, you should still do a backup just to cover your assets, your able to keep your OS, files and programs intact. Hope this helps!

suzie_q971, You may need to find AL707 driver and download /install it to see if that fixes problem. Software may have been corrupted when new drive was installed on your laptop. Could also be "screen resolution" settings were altered by the technician when doing the laptop repair. If all else fails to work, return unit with monitor and have the tech have a look at it and tell him it worked with the al707 external monitor before. 12fixlouie

HI:
You have to sometimes tell the laptop what to display, either externally, internally or both. On my laptop is is done by holding down the function key, and hitting F8 key, but your model might be slightly different.

Try to reinstall the drivers for the monitor and see if that works.

First install another monitor so Windows will load.
Then right click on "My Computer" and select "Properties", then click on the "Hardware" tab and click on "Device Manager" button. In the list and click on the "+" sign next to "Monitors" then right click on the monitor in question and select "Uninstall", then click "OK" and close all windows and "Shut Down" your PC. Install the monitor in question again and start your PC and wait 10 minutes or so and XP will set up the monitor like it's the first time you installed it.
I hope I understood your issue and Good Luck.

This is a communication issue starting with your docking station. Sometimes updated drivers are neede to insure that a device works with all devices between your pc and your laptop. Check on Dells website to see if there is an updated driver. In additon you may want to run the cd that came with your monitor, they are always shipped with a cd with drivers on them!
