"Scale image - maintain aspect ratio" missing.

I have notebook with ATI Mobility Radeon X600 and widescreen 15” LCD panel. I have tried Omega drivers (based on Catalist 6.3) and official ATI Mobility Catalist 6.2 – 6.4, but in spite of my panel is wide aspect and driver shows its resolution correctly (1680x1050), there is no scale option “Scale Image - maintain aspect ratio”.

Had anybody have the same problem and now have resolved it?

The option is there in the currently posted Catalyst Mobility 6.4 driver and Catalyst Control Center.

What do you have installed now?

I have installed Catalyst Mobility 6.4. It's very strange for me but there are only two options: 'Scale image - full panel size' and 'Use centered timings' in CCC at Notebook Panel Properties page. Though at the same page I can see "Maximum reported resolution" is 1680x1050 (wide aspect).

Why CCC doesn't show option “Scale Image - maintain aspect ratio”?

If look deeper: how does CCC decide whether option “Scale Image - maintain aspect ratio” available or not?

Anyone else experiencing this issue?

Well let me look into this. I wonder if there are others who are experiencing this exact issue.

For example the same issue with no result was discussed there:
http://www.hardwareheaven.com/mobility-radeon-drivers-support/98034-scale-image-while-maintaining-aspect-ratio.html

It looks like some notebooks with wide aspect panels and ATI Mobility Series has “Scale Image - maintain aspect ratio” option but some has not. So, to my mind, an answer on the quesion "How does CCC decide whether option “Scale Image - maintain aspect ratio” available or not?" is main point to start resolving this issue.

Also, I wonder where does a scaling algorithm take place: at driver level, or driver just controls algorithm that embeded into ATI videocard?

Hi, I have the same problem.
My noteboks is: RoverBook Navigator W571, ATI Mobility Radeon X600, I use resolution 1680x1050, but option “Scale Image - maintain aspect ratio” in Catalist 6.4 don`t present. And It`s really problematic gaming with resolution 1680x1050 [color=#800080]

Same thing...

I also have the same issue (X600 too). Far as I can tell, the only way I can get it, is to go back to the 6.1 drivers, which were the last ones to have that option (for me).

IIRC this is because some notebooks use analogue screen connections instead of digital (or other way round), or maybe IDRC

But my MSI MS-1029 has this option in all Catalysts. I'm interested in how CCC decides if this option is available though.

Well it's back for me in 6.5

Funny for me MobileCAT6.4s reverted back to ControlPanel so it was not even an option,now with 6.5 they've returned (from 6.3);

Hello the guy above! How can you obtain the maintain aspect ratio option? Just update the driver and ccc to 6.5?

My vedio card is X600 SE and my laptop is made by Toshiba, I tried to update my driver and ccc to newest 6.5 but nothing happened, there is still no maintain aspect ratio option.

ml1710 is on a distinguished road

Hi,

I'm not running a laptop, but I have the same problem. I've searched far and wide for a solution to this problem but there doesn't seem to be one. It only occurs when using an analogue connection for your monitor, otherwise the option shows up perfectly with DVI.

Any help would be appreciated


P.S.

For those who are desperate:
Here is a technique that is imperfect, but still might help a little.

Unfortunately, that's not true, ml1710. I'm running an ATI x1600 attached to a Dell 3007 monitor via DVI and am also missing the "Scale image - maintain aspect ratio" option. Is there any way to fix this?

I did not have this problem with nVidia, but nVidia's AGP cards don't support the 3007 so switching brands is not an option.

Pissed Off

This subject is so old... people have been complaining about this since like catalyst 3.5 or somethin. You would think it would be resolved by now. I sent a ticket to ati for this myself. Their response was lame. This PISSES ME OFF!!!!!!! I have a laptop computer with a 15.4 inch display and a radeon 9000 IGP. I, too, am missing this aspect ratio option. He gave me this bs about ati support being the manufacturers problem. He also told me if it was a desktop problem, then it must be a fault of screen drivers, which is extremely lame... especially if nvidia doesnt need screen drivers. So I finally managed to make him pinpoint the problem. I have no idea if he is bsing (tech support people dont always konw what they're talkin about), but he seems believable. I asked him about the issue where a screen has no drivers. Here is what he said:

"Then you would have a problem with the monitor. If it does not have drivers and relies on EDID information there will be issues. It is a similar problem that the laptops have. There is no information provided by the screen to the drivers, the dirvers have to be custom written for the display."




So if any of you good programmers/hackers/reverse engineers can figure out how to write a screen driver or spoof the EDID or somethin, then maybe we can get somewhere. But still. THIS IS SO LAME!!!!!! SCREW YOU ATI!!!!!!!!

At the moment, my laptop is being repaired so I cant try cat 6.6. Has anyone tried it yet? Not that there is much hope they fixed it...

Catalyst 6.6 didn't fix anything. I am still stuck with stretched screens at anything other than native resolutions. This doesn't hurt much for modern games, but it makes older low-resolution titles like MAME and the RealArcade games painful to play.

The option appears for certain notebook configurations and for others it doesn't. We are currently looking into it.

As soon as I hear something, I will post an update.

As for your notebook configuration, the Radeon 9000IGP is not supported in the current mobile driver.

This does not matter. This issue has been determined multiple times not to be driver specific. The people that have the option will have it on any driver and the people that dont will not have it on any driver. I believe the only person that can fix the driver itself is ATI. The only thing we can do is try some hackin in the areas I suggested above. I am extremely convinced that I have accurately pinpointed the problem. But it seems no one wants to try it.

I've been looking into this problem for some days now, since I replaced my 7800GT with an X1900, and I think I have found a solution.
At www.ngohq.com you can download the unmodified ATI drivers, not with Catalyst Control Center but with the old style control panel instead. The control panel needs to be installed seperately, so it also might work with existing driver installations.
Contrary to the CCC, the control panel allows me to select scaling while maintaining aspect ratio.
I did not check, however, whether the CCC still functions with the CP installed. If it does not, you might need an utility like RivaTuner for overclocking, since I haven't been able to figure out how to do this with the CP.
I don't know if this works for other cards as well, but it works fine here.

Thank you reaping ant but your solution cannot share with mine

I 've looking for this problem over a year since I brought this laptop (nx8220), I think I may have buy another laptop with nvidia graphic instead of ATI if they still don't solve this problem.

I like ATI but with this support for driver I don't know what will be the problem next time.

I have a Toshiba with a Radeon Mobility 9000 IGP that has the Fixed Aspect Ratio scaling if I install the original older driver that comes from Toshiba, but I lose it if I upgrade to a more recent version of the Catalyst driver series. I would like to get this functionality back.

I was looking through the older drivers INF file for any potential clues to what might be going on and I came across this entry:

[ati2mtag_RS300M_SoftwareDeviceSettings]

HKR,, DALRULE_GETLCDFAKEEDID, %REG_DWORD%, 1

In the Toshiba INF it has a value of "1" (on) but in the INF from the more recent revision of the driver it has a value of "0" (off). However, I don't know enough about INF/Registry entries to really do anything useful with it. I know EDID has been mentioned before as having something to do with this situation so I thought this might be helpful.

The link below is to the full INF:

http://members.aol.com/miscfilestorage/CX_15460.inf

If the entry I mentioned isn't anything important I figure the answer must be somewhere within the older drivers INF file since the entries in it are much different than the modern drivers INF. Hopefully someone that knows more about how these drivers work and the structure of the INF's can do something with it.

Is this helpful to anyone working on the ATI "Fixed Aspect Ratio" problem:

http://ati.amd.com/developer/sdk/ccc...roperties.html

http://ati.amd.com/developer/sdk/ccc...mageScale.html

The second link says that UseCenteredTiming=0, ScaleFullPanelsize=1, and ScaleMaintainAspectRatio=2.

This setting must be stored somewhere, otherwise it wouldn't remember what is selected. We just need to find out where it it stored and change the 0 or 1 to a 2, so it uses that setting instead.

I could be wrong since I really don't understand exactly how this works, but hopefully someone around here will know how to use it or knows someone that can make it work.

Does anyone know if we can access this using the CLI or the DeveloperConsole directly?

This is something else I found when I switched between "Use Centered Timings" and "Scale Image - Full Panel Size" in the Catalyst Control Panel, The only thing that changed in my registry was the same value in two different keys. The two keys were:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Video\{4F48FFD8-64BC-11DB-8B57-806D6172696F}\0000]

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Vi deo\{4F48FFD8-64BC-11DB-8B57-806D6172696F}\0000]

The value that changed was:

"DALATI RS300_Index0"=hex:00,00,00,00,00,00,00,00,00,00,00 ,00,00,00,00,00
For "Use Centered Timings"

and

"DALATI RS300_Index0"=hex:00,00,00,00,01,00,00,00,00,00,00 ,00,00,00,00,00
For "Scale Image - Full Panel Size"

Everytime I switched back and forth between the two the only thing that changed was this value in both keys. Hopefully someone will be able to use this information to come up with a solution to the Fixed Aspect Ratio scaling problem since I believe it's just another value (i think it's 2).

Sorry for all the posts, I've just been putting stuff up as I've been finding it while investigating this problem.
