Getting input signal out of range error

[KitKatLamb]

I am using a Dell computer with the HP L1908w monitor as a 2nd screen, linked by a HDMI Male to VGA Female Converter Adapter Cable 1080P for PC HDTV DVD Laptop and had the same annoying message floating around the HP L1908w screen saying "Input Signal Out of Range" when ni first connected.

I found where the problem is and how it can be fixed!!!

The answer is all parts are the problem - computer feed, through adapter to monitor and they just need straightening out and be made compatible.  It's not that it isn't detecting the signal, just that it is out of sync in terms of parameters!

Here's the solution:

Get into the Display settings window (easiest way is to type "Display" in the bottom left hand corner search bar) 
Once there, ensure you you have detected, identified and extended all the Displays so you have split the screens out (an option in the drop box about 3/4 down the screen)

Highlight the HP L1908w screen (should be Screen 2 if you only have the two - laptop screen + 1 spare monitor)

Click "Advanced Display Settings"

Click "Display adaptor properties for Display 2"

Find the pop up box that follows (had to minimise the rest of my windows to find it) - mine is entitle 'Generic PnP Monitor and Intel(R) HD Graphics 520'

Click the box (bottom left hand side within white background area) "List All Modes"

Once in there, select the option that the bouncing message is telling you its best to set it to (mine was only out by 1 Hertz  - it was set on 59 Hertz instead of 60 Hertz, all other settings were the same).

Once selected, press OK on the "List All Modes" box

Then click Apply back in the 'Generic PnP Monitor and Intel(R) HD Graphics 520' box

Also make sure you click Apply back in the Display Settings box too

After I did all of the above, the bounding message went away and the screen was much clearer!

Good luck!!
