This thread is for nw9440 users who are currently battling with HP, trying to get a fix for the DVI problem with this product.
Please read the original source of this problem before posting to this thread (just so that we don't have to keep covering the same old ground and dilute the DVI issue with the other GPU overheat issues)...

To save you reading too much, the DVI problem has been traced to some sort of safety cutout when the GPU temperature gets above a critical level. The GPU temperature reaches these ultra high temperatures simply based on the particular colour that is displayed on the DVI connected monitor.
There have been many reports of graphics related issues with this product, most of them have been related to overheating of the GPU. And most of them can and have eventually been solved by HP fitting/replacing the GPU heatsink properly.
This DVI problem is not related to those other problems, but unfortunately it got caught up in them a bit because it does manifest itself by instantaneously overheating the GPU when certain colours are displayed.
In a nutshell, the problem is this...
1. Connect your nw9440 to a high-res external monitor via the DVI port on an HP docking station.
2. Set the external display resolution to WUXGA (UXGA and WUXGA are the only officially "supported" high resolutions). (but anything higher than UXGA will cause the problem though)
3. Immediately notice that the nw9440 fan starts coming on more intensely than usual, and at odd times and often quite high speeds - considering all you are doing is nothing more than web browsing etc.
4. SAVE ANY UNSAVED WORK YOU HAVE OPEN - I'm not joking here, please do it before the next step - you have been warned.
5. Open a so called "colour of death" full screen, and gasp in utter disbelief as your nw9440 immediately powers off. (a COD can be found attached to the second post on the HP forum thread or just visit http://www.rockbox.org/ where a COD is used for the background.)
Again, before posting please, please make sure you are familiar with this problems origins and history, which can be found here ...

This thread exists so that users can have an impartial (ie. non HP managed) forum to discuss where they are at with HP and this issue. It can also be used as a means of privately passing on sensitive reference information (such as HP support case numbers) if the need ever arises.
The current status as at time of writing...
HP have given some users a beta BIOS to test. It seems that HP have simply removed the safety cutout in this BIOS. ie. the fan still goes to very high speed and the GPU still gets very very hot. They are currently trying to convince users that this fixes the problem.
