No Full Screen using Windows 7 RC & Radeon 4870 in HDMI mode

Hi

I recently installed Windows 7 RC on my home PC to try it out. I have been using Windows Vista prior to this using an ATI Radeon 4870 on my recently purchased Acer H223H (23", 16X9 ratio, 1920*1080 - Full HD, 2ms, DVI, VGA, HDMI, Speakers) screen via HDMI with no problems.

Since I installed windows 7, I cannot get my screen to display full screen via HDMI, yet the resolution is set correctly. I fiddled with all the settings and even installed the lastest 9.8 Catalyst drivers with no luck.

I then tried connecting the screen via VGA & DVI instead of HDMI and it worked 100% correctly.

I did some searches on the net and the closest thing I could find wat the following relating to Catalyst Drivers:

" Known Issues Under the Windows 7 Operating System


Certain resolutions above 10 x 7 might not full screen for specific HDMI displays "

Fair enough, but this dates back to Catalyst version 9.3, or even possibly earlier versions. We currently have version 9.8, which is already 5 months newer!?!?

Has anyone had similar experiences like this???

Spawn_eternal,

The Windows Hardware ecosystem is incredibly broad and offers a large selection tailored to very different needs. This is one of the things that makes Windows appealing to a variety of different users. To ensure that the user has a great experience with the devices that the user loves, we have been working closely with all our top partners including the top video card manufacturer. ATI and NVIDIA, for example, are both featured in our Ready.Set.7 campaign, where our top partners showcase their readiness and improvements with Windows 7. However, we cannot control the marketing, HW requirements, and life cycles of our vendor’s products.

Great, i'll give it a bash and report back to you tomorrow!!!

Yup, i forgot to get back to you, but yes, the under/overscan setting did the trick. Thanks guys.

Wow, I am so happy I found this thread. This fix worked for my I-INC monitor. Thanks guys.

thank you all so much for this thread. it fixed the problem, and i would have never found it myself.
sshm, i am using windows 7 64 bit and the latest catalyst driver, 9-11.
the option for underscan/overscan is there just not easy to find.
you need to choose "desktop and displays",
there in the bottom left you see a little monitor, right click it and select configure.
from there, you will find the hdmi settings and overscan/underscan.

good luck and thanks again for this forum and thread.

I also had this problem when I first plugged my HD 4890 into my Asus X213H @ 1920x1080. For some reason it would remove the overscan when I set the monitor to operate at 59 Hz instead of 60, which worked until about a week later, at which point I looked around for a good two or three days (to no avail, unfortunately) and finally decided to mess with everything in CCC and found the overscan worked. This should really be in some FAQ somewhere that people can find, I know it annoyed the crap out of me and I thought the monitor was defective.

Thank you every one for solving my problem .....gracias

Was having this same problem after latest driver update on my 5850. But now solved
Many thanks!
