stretch screen

My wide screen distorts things. How do I use the entire screen but not stretch and distort things so that rectangles look like squares?

You don't. Every screen has a "native" resolution. In the case of the new super-wide screens, this is often 1440x800 (or something like that). A pixel is a given dimension -- set by the resolution. You can't change that.

Your only options are the following:
1) Live with the distortion
2) Change the screen resolution to remove the distortion -- but then live with the lower resolution.

Well, the first thing I had tried was also installing the latest XP drivers and for a month or so all worked pretty decent. There was some limitations, I guess due to the lack of DirectX 9 support. For example, Flash videos could not be displayed in Fullscreen mode (caused BlueScreen) unless you disable the graphic accelerator (right click on the flash video -> settings). Also, no video playback was possible with the VLC media player (sound only). You have to deactivate Direct3D etc. in order to get it to work (Display Resolution -> Exended Settings -> Troubleshooting).
However, after installing Service Pack 1 there was suddenly BlueScreen over BlueScreen, apparently caused by ati3duag.dll. Eventually, after doing lots of research, I found a solution that worked perfectly for me: The ATI display drivers included with Windows Vista. You can download it over here:

Extract the content of the Zip-Archive to a directory of your choice. Then go to System -> Hardware and Sound -> Device Manager. Right click on your video card, choose "Update driver", then "Search your computer for driver software", then "Choose from list...". Uncheck "compatible devices". At the bottom right is a botton "Have Disk", choose the extracted folder. It will automatically detect and display the video card model "ATI Mobility Radeon 7500". During installation process, Windows will ask you if you want to install altough the driver has no certification. Simply choose "Install anyway".

That's it! Now I can even play 720p HD Youtube videos smoothly. Insane!

Question to love4all

Hi Love4all,

I tried these drivers in the past and, although it allowed me to use the intended resolution, I had to disable the graphic accelerator with a consequent increase of the main processor efforts (the fan was allways running at max speed). I think that was the best we all did here in the forum.

Did the SP1 made a difference and allow the card to actually use it's own processor or is it still the same but without the bluescreens? How is the main processor working? Are you using the graphic accelerator? What about the aero theme, does it work? and last but not least: did the windows score change?

I can't actually test it for now since I took my hardisk (toreplace my creative zen disk), and still haven't bought a new one.

I tried using seven for a while on my evo n610c but after the card driver faillure, I end up installing linux. Now that I'm about to install the new drive, I'm considering give it a try again, depending on your advice...

Good to see you, Carlos!

Actually I'm not sure if SP1 changes anything at all regarding the video card, but what I've noticed by now is remarkable. I didn't check the CPU's behavior while the XP Driver was in use (all I know is that I could work with it) but as for now it varys from 75% to 100% while playing a 540p H.264 Basketball game. Now that seems pretty acceptable to me. And I haven't had not a single Blue Screen since the installation of the Vista drivers.

Graphic accelerator is enabled at maximum and works far better than what I expected, as I said even HD videos can be played (although I have to admit that I didn't tried it out before). The only app still refusing to accept the graphic accelerator is VLC Media Player. Same as before, the video stays black while playing and only its audio track can be heard. But that's OK for me, I simply switched to Media Player Classic Home Cinema and it works like a charm and even more, it seems to go a lot more easier on resources.

Aero Glass doesn't work, as I expected due to the reason that the Radeon 7500 has no DirectX 9 support (which is crucial for Aero according to Microsoft). However, I can get over it since the functionality of the OS isn't very restricted as a result, although I do love Aero's graphical design of course.

As for the Windows Experience Index, I was frankly surprised. Despite its overall score of 1.0 (3D business and gaming graphics performance), the "Desktop performance for Windows Aero" was 1.9, however. Now after updating both graphic components are at 1.0. Don't know what that's supposed to mean, perhaps because the Vista drivers are not certified by Microsoft. But I don't care anyway as long as it works so fluently.

Hope I could help you out somehow, always available for further questions.

Bookem Dano! Your Post/Solution is 100% Spot On

If you are using an IBM T-40 with Raedon 7500 Graphics card, simply download the XP drivers, and follow Dano's instruction to the "T". I've had several of these that we upgraded to Win7, and it (the beliow instructions) never failed. Granted, I've seen many other instructions here that do not work, and will cause definite BSODs, or system hangs. AGAIN, GOOD INFO DANO!

Actually your information about the 7500 driver is not accurate. You can download the XP driver from lenovo website and run the executable so that it creates a folder on c:\drivers\win\display. Once that is done go into device manager and click on the Standard VGA adapter and update the driver software. When prompted, browse for driver software on your computer and point to the folder on c: drive. It should automatically find your 7500 driver and will allow things like 3d text etc to work in screensavers, and other video settings.

Actually I also came to the conclusion that the XP Drivers work best. The Vista Drivers cause problems with Windows Media Playback which makes it impossible to watch any video file on my T42.

However, the Vista Drivers also have some advantage compared to the XP Drivers. I never had a single bluescreen, while with the XP Drivers, I've already had several ones. Watching Adobe Flash in Fullscreen is possible, but some other plugins immediately cause the system to crash with BSOD error message "ati3duag.dll", for instance the Veetle Firefox plugin.

So altogether, the XP Drivers are not perfect, but as close to working with Windows 7 as you can get.

download the ati3duag.dll from my dropbox (click on the name) and place it in C:\windows\system32 (you have to be admin and have allowed yourself access to the folder (right-click>properties>ownership...))

I have gone back to the old and reliable XP, so it's kind of hard to do it all again just to test this new driver. Can you please post your tests and results so we know ahead if it even worths the effort?
