Win7 + ATI + 1080p monitor = :(

[ExcaliburMM]

The monitor is a HannsG 23.6", 1920x1080.

Before I sent back my ASRock mobo for having a dead memory channel, I got to run my i7 rigg, w/4870 1GB on Win7 64bit, and as before on XP, had to use overscanning in the CCC to get the image on the entire panel. This was the only way to do it too, no other setting helped.

Unfortunately, on Win7 this was a problem. On XP the image was perfectly fine but on Win7, the image was blurry, text was barely read-able, and since the monitor is only 23.6" I'd really rather not use Windows larger text size settings as it makes everything look funny.

Anyone have an idea as to why:
Why Win7 causes problems (Possibly due to different drivers? Used latest on Win7, maybe 1 or 2 versions old on XP.)
Why I even have to use overscanning
If I should switch out my 4870 1GB for a GTX275

Are you sure you didn't have things on a higher dpi on windows xp. The other thing you could try is to adjust cleartype in windows 7. It's under apperances and personalization-->fonts

Is it set up properly in CCC?

That's a really weird problem for a real monitor. I'm using a 5770 on a 42" TV so setting underscan or overscan is normal. However you shouldn't need to do any of that for an LCD monitor since they should be set to do 1:1 mapping. Perhaps you should look at the features/settings on your monitor and see if there is an option to set 1:1 pixel mapping. I know a lot of the new monitors try to act like TVs and some even have tuners (so they actually are TVs). Also how is your monitor connected? DVI, hdmi, vga? It might act different depending what kind of connection you use.

@Mad Yes I'm sure.

@jlee That topic just seems to suggest settings I had already tried or reverting to older drivers. Though trying older drivers is no problem for me since most of my games are older.

@Blanket Monitor is connected DVI to HDMI cable since the monitor only has HDMI and VGA ports.

My build wont be running till this weekend when the new motherboard gets here, so I can't try any proposed solutions quite yet.

Funny, I've got a very similar configuration. i7, Win7 and ATI HD4870 1GB on a 23' 1920X1080 monitor. I doubt its a problem with your GPU, so I don't think swapping GPU will solve the problem, but I may be wrong.

I'm using 4870 card with Win7 x64 and Asus VW246H(24" 1920x1080 in DVI mode) with no issues,think I have used last 3 or 4 ATI drivers (Since Oct last year).

All I can think of is try a different cable...Does it happen in VGA mode as well?..also some monitors come with INF drivers(however if its plug and play monitor then you should have no issues).

I have a 4870 1gb and Windows 7 and also ran into similar problems. The overscanning options do help a bit, but the text on my lcd is still a bit blurry. I'm not running a true monitor though as I have an LG 37" TV hooked up through HDMI, but my same set up with Windows XP was fine so I'm not sure where the problem lies.

I'd say it has more to do with your chosen monitor than it does with Win 7, ATi, and 1080p. My 5850 runs 1080p through Win 7 on a 23" monitor just fine.

I've set up my 1080p television in windows 7 several times over the course of getting my HTPC to work with strangely varying results each time. I've noticed that sometimes, seemingly at random, something decides to do some scaling at 1080p when I initially set things up after a new Windows install. The result is that things are blurry and off-center regardless of the resolution. I can't quite recall what is that I did to fix it each time, but I remember going back and forth between the resolution settings in windows and CCC and also fiddling with the HDTV resolution/refresh settings in CCC.

It also occurs to me that the only reason that overscan settings should be an issue is when CCC detects the display as a television. That's the only time it makes sense to reduce the image size to compensate for something present only in televisions. All I know is that I have never had to mess with the overscan setting with actual monitors, therefore CCC must somehow know that overscan is not an issue in those cases. All this means is that, considering that what you have is an actual computer monitor, there is some detection error going on which may have screwed things up from the get-go.

Just a note, two old cards, a 9200LE and a MX 440 both handled the display just fine under XP. =/

I take you learned your lesson on that one. redhell is no good my friend...

I think your issue has to do with ATI and 1080p over HDMI. Possibly ATI + Win7 + 1080p + HDMI. You should add HDMI to the title.

The first thing you should do is try VGA just to see if it fills the screen properly - my guess it it will.
--------

Here's my experience:

going from my Dell Studio 15 with a 1080p screen and ATI 4570 video to a 46" Samsung LN46B630 LCD, the screen by default underscans over HDMI. Once I went into CCC and bumped up the overscan it fills the 46" lcd perfectly at 1080p, and it remembers this setting everytime I disconnect and reconnect the HDMI cable. No blurriness issues.
----------

On my desktop, I have no issues with a Radeon 3850 or 4870 on both a Dell 2408WFP and 2709W using Windows 7 (1920x1200). I've tried connecting to the LCDs using either DVI and HDMI and they both have no issues filling the screen properly at 1920x1200 or 1920x1080.

It could be a 1080p screen issue in conjunction with ATI cards and HDMI. That's so bizarre that the image comes up blurry for you though - I've had no problems with blurry text on my W7 desktop or laptop over HDMI.

Running Windows7 with ATI graphics card in 1080p just fine. Using a 22" ViewSonic model # VX2260WM. Currently have the monitor hooked up by DVI.

Most likely the ATI drivers, it's a lottery if they work right.
