How dark is a plasma in a completely dark room

No, I had to exaggerate the levels to make sure that the image would be understandable regardless (within reason) of the setup state of any reader's monitor.

I thought so, it's quite amazing how much there is to learn beneath the surface of all this.

I'll read up on the info you mentioned above so I get my head round it fully, particularly the safety margins as I do not understand that! Thanks again

You don't really need to understand the safety margins as such. Just make sure that your source sends out the image so that it maps the black and the white levels correctly.

If you value your system enough to spend £15 on a Blu-ray test disc for video and audio then I can heartily recommend Digital Video Essentials HD Basics link Despite the "Basics" name it has everything you need to do a thoroughly comprehensive job of setting up both the video and audio sides of any system. It's one of the test discs I carry and use a lot.

The pattern that you would find really useful is this...

The three dots at black and at white show the correct dynamic range for video. If you get the output setting wrong from the source then the test pattern will show it really clearly. It's a simple and very effective tool for this kind of setting.

If you've spent hundreds or even thousands of £££'s on your system, and countless hours researching and tweaking, but the idea of parting with £15 is just too much to bear then there's always AVSHD It's a collection of test patterns put together by enthusiasts and offered as a free download that you burn to Blu-ray then play back from a BD player.

Another disc worth looking at is Spears & Munsil. There's a short thread discussing the merits of various discs and downloads here
 
Oh are you aware that THX mode turns off the pixel orbitor? Which can increase image retention. I find "normal" mode the best for black levels. Its been proven on the AV Forums.
 
The link doesn't work to buy the basics blu ray

Yeah I know thx turns off orbiter, but I find it looks the best of the modes. I'll try normal and check the black level, it would be a shame to not use it, it was one of the benefits of the Gt30 that it had thx

I put a new wallpaper up of a starry galaxy and also on an LCD, needless to say the plasma really did a good job! In fact the lcd looked really really bad! It couldn't keep the stars bright without washing out the blackness, it has eased my fears

I have also set my wallpaper to rotate to alleviate the IR
 
The DVE HD Basics disc used to be available from Amazon, Play and all the other big European online retail sites. This time round I have found it here and here The latter site claims that the disc is Region A locked. I don't know how accurate their information is though. My copy plays in all regions. I have used it in several customers UK PS3 consoles.
