I have a LG Flatron W2442PA monitor.
Manual says "User must use shielded signal interface cables (D-sub 15 pin cable, DVI cable) with ferrite cores to maintain standard compliance for the product".

I have been using a DVI-DVI cable (2 x 9 pins) between Desktop PC (1 x 24 pins) and the LG Monitor (1 x 24 pins) with no issues and it still works.

However, I have a new HP ProBook 470 which uses HDMI 1.4a, so I purchased a Dynamix HDMI Female to DVD-D (24+1) Male Swivel Adapter from PB Tech.

The LG Monitor will not see the HP Laptop (with HDMI) or a Dell laptop E6420 (with HDMI).

Now I know virtually nothing sbout DVI apart from finding a web page on how to tell the difference from the pin configuration.

I assume the adapter (24 pin) is wrong for the cable and monitor.

What cable (DVI - HDMI) or adapter should I buy?
I am in Auckland and know most of the good PC shops

I've used HDMI to DVI cables a number of times and had no issues at all.  DVI and HDMI are electrically compatible (by design) so the cable needs no electronic chips in it at all.

Consider trying to hook the laptops up to a TV with an HDMI to HDMI cable to see if you can get a picture.  It may be settings on both laptops that you need to adjust to get the 'second screen' working.

If you have no luck and can be bothered coming to me in west Auckland we can have a look together.

Did you every buy that HP Envy X2?  I'm typing this out on mine and love it.

Solved. The cable is/was faulty. I tried connecting to the TV and with the current cable, there was no picture, tried another and it was OK. I never connect a laptop to a TV so I had never thought of it.

Many thanks

PS No I hesitated for a number of months and finally bought the HP Probook 370 (17") because I decided this laptop was just a desktop replacement and would only need moving very occasionally, plus the screen was bigger. It came with Windows 7 (and 8). It took 6 minutes to boot and even then it wasn't fully operational i.e. connected to internet. Took Windows 7 off and put on Windows 8 (which I am used to, without the touch screen) and it boots a lot faster and just seems faster.

Great to hear you got it sorted.

Fair enough with the laptop decision.  The Envy X2 is underpowered in order to give the huge battery life.  It's saving grace is the Solid State Drive, so programs load quickly and the boot time is very good.

Win7 on your ProBook should have been just fine.  It sounds like there was a software fault or the machine needed some serious software cleanup.  Reinstalling Win7 from the factory CDs would have restored good start-up time.

If you are ever inclined to throw some money at the laptop to make it run faster still, replacing the internal hard drive with a Solid State Drive will halve your boot time and the machine will feel snappier throughout its life.  You can put the hard drive you remove into a USB caddy.  All of the machines I use regularly now have SSDs.  (I can justify the expense for work purposes.)

Cheers
Mike
