Just recently got a philips monitor: http://www.dicksmith.co.nz/product/XC9012/philips-23-quot-fhd-led-monitor-236v3lsb

It came with a VGA cable but i went out to buy a DVI-D cable: http://www.dicksmith.co.nz//product/XH9596/dse-dvi-d-to-dvi-d-18-1-single-link-cable-1-5m

Came home to try out the cable but when i swapped out the VGA cable for the DVI-D and played a movie on my pc, either the image looks the same or it may look slightly worse then before. Can anyone help me?

It might sound like a stupid question but what is your actual problem?

A DVI cable isn't going to magically deliver a picture that's necessarily any different to VGA. If the picture looks worse do you have it set to a correct aspect ratio?

+1 what sbiddle said. What is the problem?
Colour, Brightness, Pixelation, Banding, Jerky play back. What?

What model graphics card?

Are you using the same refresh rate for VGA and DVI. Some cards can have completely different settings depending on whether you are using VGA or DVI. including resolution.
Same goes for monitor. Most will have / keep different settings for colour, brightness etc for each input. So the colour, brightness, contrast etc settings the monitor uses when using VGA input could be completely different from the DVI input.

Picture isnt as sharp and clear.
Graphics card is NVIDIA GeForce GT 430

Screen refresh rate is 60 Hertz which is max

Have you got both cables plugged in? what could be happening is that your VGA cable might be monitor 1 and DVI monitor 2 and they could be different settings.

Check which monitor you're looking at in windows 7 it's in the control panel under display click identify - tells you whether you're looking at monitor 1 or 2 (or more)

The VGA cable isn't connected, only the DVI-D cable is

Did you do the monitor test mentioned above? which OS are you using?

Using windows vista.
Sorry not very tech savvy

Goto Control Panel

Then Display

Then on left hand side adjust resolution

There is a drop down for Display - because your video card can output to multiple screens you might find if you select monitor 2 in that drop down that it's on a different resolution - that might be why the screen looks a bit strange.

You know which screen you're looking at by pushing the identify button and a big 1 or 2 will display on screen.
