L502X - apple displayport -> VGA doesn't work?

Hi, I have a L502X. I connect it to DVI through a cheap mini-displayport -> DVI adapter & it works fine. However I had to connect it to a VGA projector. Someone in my office had an apple mini-displayport -> VGA adapter, however this gave no signal on the projector, and the laptop didn't recognise that there was a projector connected.

Is there any particular reason it obviously wouldn't have worked?

 

Looks like I answered my own question:
Mini-DisplayPort on New Dells: Resolving issues with output to projectors in Windows 7

Anyone care to say whether this matches their experiences?

 

I can't speak to the Apple ones, but I use this one from Monorpice almost daily, and it has never failed me.

For only $11.06 each when QTY 50+ purchased - Mini DisplayPort | Thunderbolt to VGA Adapter | Mini DisplayPort to HDMI / DVI / VGA Adapters

 

I've had issues with the Apple connector. Figures, right?

My home LCD monitor works without flaw through it, but when I try to hook up to a projector system at work, no dice.

 

Yes I had the same problems with my XPS 15z and using projectors,

Some work, some don't, have several I tried with, maybe 40 % dont work with it.

so I orderfed the monoprice one to try today.

 

My apple one works for DVI, may or may not be revalent but just thought it might help.

Also another person told me it shouldn't matter

 

Just to follow up...

I purchased the Dell-branded Mini-DisplayPort-to-VGA adapter and it works flawlessly. The Apple one does not.

Both work fine with my home Dell LCD monitor, but the Apple one fails with the projector systems at work.

I have no idea why, but for the record: Apple sucks ;-)
