Poor HDMI image quality on certain monitors (Text blurry, appears oversharpened, and colours dull)

From what I understand of the problem, my monitor, a Westinghouse L2410NM and other models from various manufactures transmits a confusing EDID to the grahpics driver. The graphics driver thinks that the monitor is an HDTV and outputs the wrong type of signal. I have experienced this exact same problem with both ATI and NVIDIA cards, however, in both cases, I was able to solve the problem. I am sure that a solution exists for Intel Graphics, we just need to find it.

As it stands, my HDMI output is basically unusable due to the following effects of the problem: Text is blurry, everything appears oversharpened, and the colors are dull.

Because this problem is exactly the same as the problem I had with my Nvidia card, I expect that the solution will be simular. The NVIDIA fix only requires a simple registy edit (after drivers installed), or driver inf edit (before drivers are installed). These edits override the monitor advertising itself as an HDTV. More information can be found here:

What I need to know is where I can make those corresponding edits to the Intel drivers or location in windows Registry.

Currently I'm using Windows 7 Build 7100 with the newest Intel WDM 1.1 prerelease drivers that I've got from windows update:

Driver date: 2009.05.06.

Driver version: 8.15.10.1749

Mobile Intel 45 Express Chipset Family (GMA 4500M)

Or if no one can address my question here, can you please let me know who I should get in contact with at Intel to address this issue. Thank you.

By any chance do you have a link or info on how to resolve this for ATI? I have a Radeon HD4650.

Thanks

So do you still have this issue? Are you using a Retail version of Win7? Have you downloaded the latest graphics driver for you system here, http://www.intel.com/support/detect.htm http://www.intel.com/support/detect.htm ?

Hello. I am still experiencing this problem as of a few driver revisions ago. I will check once more with the newest drivers, but I doubt there will be any resolution without user intervention. I also made Nvidia and ATI aware of these problems years ago and they never did anything.

Just as I had expected. I installed the newest drivers I could find 8.15.10.2141 (64bits) (15.17.7) and nothing has changed. Running Windows 7 RTM with all updates.

Intel any help?
