I have purchased a VGA/VGA splitter and a new monitor (Hanns.G 21.5" model HE225). After plugging the splitter to the NVidia Graphics card on my HP Pavilion p6-2489ea Desktop PC on starting Windows 8, both my existing Hanns.G HN198 Monitor and the new monitor show the same display.

On setting the display properties only one monitor is detected and both monitors have been identified as 1. I have tried numerous restarts and detection but Windows still only recognises one monitor a Generic Non-PnP monitor,

Running the disk that came with the monitor to load the drivers doesn't have any affect as this appears to be only for Windows 7 and apparent the device should be recognised on connecting in Windows 8.

The N-Vidia control panel recognises 1 Analogue Display and rigorous display detection does not find the other monitor.

---------------------------
Additional Displays Not Found
---------------------------
Rigorous display detection was unable to find additional displays. However, some televisions are not detectable like computer displays.
If this is the case, and you are certain your television is connected, the television connection can be enabled and your television will be available.

Would you like the television connection enabled?
---------------------------
Yes No Cancel
---------------------------

I have clicked Yes to the television connection enabled, but the Force Television connection was greyed out. Therefore the NVidia control panel did not help detect the dual monitors either.

Would anyone have suggestions on how to detect Dual monitors using the splitter and for Windows 8 HP Pavilion p6-2489ea Desktop PC?

You cannot split a VGA connector to drive two monitors independently. The best you can do with a VGA splitter is run the same source image to multiple displays, as you indicated you were able to do above.

In order to drive multiple monitors from a single source, you must be using a DVI connection or better, preferably a dual link DVI for the increased bandwidth required.

If your computer did not come with a separate graphics card, and your motherboard's integrated video does not include a DVI connector, you will need to buy a separate graphics card and install it in the machine (although most graphics cards now come with multiple outputs anyway, so this almost becomes a moot point).

I have one display adapter Nvidia GeForce GT 630 with a DVI-A port. The PC came with a DVI-A male/ VGA female adapter which I connect the original monitor too. I have then tried to add the VGA male / dual female splitter to connect two monitors. The new monitor has VGA DVI-D inputs. Which components should I purchase? Do I really need to get an additional Graphics card?
 
I ran a search on the model number posted above and found this page: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c03735135#N524

If this info corresponds to your machine, leave the DVI to VGA adapter plugged into the DVI port on the GT 630 (it's actually a DVI-I port on the card, not DVI-A) for the old monitor, and then get an HDMI to DVI cable (HDMI male to DVI male: example shown here), and plug that from your new monitor into the HDMI port on the video card.

I'm telling you all of this under the assumption that this is your new monitor. There was no model I could find exactly matching the model Hanns.G HE225. The link above is for the HE225DPB.

Correct a HP - Pavilion p6-2489ea Desktop PC and a Hannspree HE225DPB 21.5 inch Full HD Widescreen LED Monitor (1000:1, 5ms, VGA, DVI-D, 1920 x 1080), Thanks will purchase HDMI / DVI cable as suggested.
