Hi all. So a solution to this issue has been found. I originally came onto this solution from this post: http://forums.nvidia.com/index.php?s...dpost&p=453829
However his post is very brief and the guide he references isn't exactly accurate for the GTX 280 so I'm going to write a new summary here.
Quick rundown of the issue and solution. So the basic rundown: The problem is that the driver is sending bad info to the tv based off the EDID info the TV is sending to the card. For whatever reason, the pairing of these Philips TVs and the GTX 280 (and some other nvidia cards) just don't play well together. The solution is to modify the inf file of the driver and tell it to ignore the EDID data from the TV altogether.
To do this, you will need to uninstall your current driver and then reinstall the drivers using a modified inf file.
1) Download the latest nvidia drivers and let it extract the installation files. After it extracts the files and goes into the installation wizard, cancel. You don't want to install quite yet.
2) Go to the folder with the extracted files. (Most of the time, this will be in C:\\NVIDIA\\)
3) Find the file called nv_disp.inf and open it using notepad.
4) So here's where things get a little complicated. You need to add the following line into the inf file in a section called [nv_SoftwareDeviceSettings_GT2x]:
HKR,, OverrideEdidFlags0, %REG_BINARY%, 41,0C,00,00,00,00,FF,FF,04,00,00,00,7E,01,00
Beware there is also a section called [nv_SoftwareDeviceSettings]. This governs other cards such as the 8xxx series 9xxx series etc. Adding it there will not solve your GTX280 problems.
5) So. I lied a bit. The above line isn't necessarily what you need. The first 4 hex numbers are the EDID identifier for your TV. It is going to be different depending on the TV you have. That line is going to tell your card to ignore the EDID info for a monitor broadcasting that EDID. For my TV (42" 42PFL7422D/37), it was 41,0C,00,00. However, unless you have the same TV as me, your EDID number will be different. The following is how you find out what your ID is.
6) Get MonInfo: http://www.entechtaiwan.com/files/moninfo.exe
and install it.
7) With your TV hooked up to your computer, run MonInfo and you will see that there's is a pane called Display IDs. Find your TV among the displays listed there and look at the Raw Data pane. You need the 4 hex numbers in bytes 8-11. So basically, starting with the 1st cell in 2nd line (that is byte 8) and then the subsequent 3 cells, that is the EDID tag of your TV.
8) Use that as the 1st 4 hex bytes of that line I mentioned above.
9) Save the inf file and install the drivers. The installer will now complain that the drivers are unsigned because you modified the inf file. Don't worry about it and install them anyway.
10) Restart your computer and voila! Your tv will now work correctly.
