HD 4870, Win 7, Hannspree HF259
Hi there,
I have seen several threads that are similar, but none with the details that I have here:
Equipment:
Diamond HD 4870 512 GB
Phenom II X3 720 BE
WD 1TB
LG Blu-ray Multi Drive
Gigabyte UD2H motherboard
4 GB of 1066 RAM
Hannspree HF259 monitor, full HD, 1080P, with a DVI to HDMI cable (came with the monitor)
I have a triple boot system setup: XP Pro 32 bit, Vista Home 32 bit, Win 7 64 bit, all operating systems have all the service packs installed. The problem I'm having is with the Win 7 install and the Catalyst software setting the correct refresh rate for the monitor.
Let me start by saying that this is mainly my gaming computer, I use it for other things also, but mainly it is my toy. Both the XP and Vista installs work great. With the Catalyst driver pack that came with the video card, my monitor and the correct hz rating (60) is recognized and I get a great 1080P (1920 x 1080) picture, no issues what so ever. The problem is with the Win 7 install, and BTW, I had the same issue when I loaded Win 7 RC.
The Win 7 64 bit installs as expected, but the video that is displayed, is not using the whole screen, although it indicates that is displaying 1920 x 1080, but at 59hz. At this hz rating, the display is shrunk about 1 inch all the way around the monitor, and directly propotional left/right and top/bottom. If I select, thru Catalyst, 60 hz, the display then expands to fill the whole screen and is perfectly clear. I installed the .inf file for the monitor and all appears to be good. But upon reboot, the display looks like it did before I started, which requires me to repeat actions above to get the display corrected. This continues each time I reboot, and only on the Win 7 install. When I had Win 7 RC installed, one time I had a message to use the default settings of the monitor show up on the Catalyst software (I think), selected yes and then never had a problem with it again, on Win 7 RC. I cannot find that selection with the Win 7 install, and I'm not sure where it actually came from.
I have seen some threads talk about the HDMI cable and quality, but this is a special cable that came with the monitor, DVI from video card/HDMI into the monitor. And it works perfectly on the same equipment with XP and Vista, so I doubt that it is the cable.
Any ideas?
Thanks, Big Kahuna
