It's by design and that's code for not going to change.
However it appears that you have some other issue. If installing the latest or other version of video driver does not correct this I would change the video card.
Ok. I've been putting up with this annoying problem that's been going on for over a year.
First, here are my specs:
PC: HP Compaq CQ5210F
OS: Windows 7 Home Premium
Processor: AMD Athlon II x2 215 Processor 2.70 GHz
Memory: 3 GB of RAM
Graphics Card: nVidia GeForce 9500GT
Display: Philips 40" TV - yes, it supports high resolution (1920x1080)
TV and PC connected with DVI cable and HDMI adapter.
What happens is when I first boot up the computer, the TV blinks constantly, sometimes going completely black for a few seconds before coming back on.
It took me ages when I first got the TV to figure out that if I go into the Screen Resolution window and change the resolution to - well - anything, hit apply, then change it back to 1920x1080, apply again, the blinking stops. I have to do this every single time I boot up my computer.
