    I installed windows 7 64x on inspiron 6400e1505 notebook . I get max resolution of 1024x768. I tried everything , but in vain.
    Do you have any idea , what could be the problem ?
    In my previous Win xp 64-bit os , I was using ati radeon x1400 and it was working. I was getting higer resolution. But when I installed windows 7 64x , the max resolution to be adjustable has been only 1024x768.
    Please help.

Hi, i own compaq presario CQ42 369TU laptop, how do i increase my screen resolution from 1024x768 to 1280x1024 or higher ?


For Windows XP...

1.
Open Display in Control Panel.
2.
On the Settings tab, under Screen resolution, drag the slider, and then click Apply.
3.
When prompted to apply the settings, click OK. Your screen will turn black for a moment.
4.
Once your screen resolution changes, you have 15 seconds to confirm the change. Click Yes to confirm the change; click No or do nothing to revert to your previous setting.

If you cannot set it any higher than 1024x768 and you have already installed the video drivers, that is as high as it can go for your hardware.

How to change screen resolution of t43 if it is


That 1024-by-768 value is the MAXIMUM supported by the computer.

The only way to go to a "higher" value is to buy a newer computer.

Im having problems with my resolution. I have a Toshiba Satellite A135 S2386. I recently downgraded to XP and the only problem is the display. It won't let me set it to 1280 x 800 or whatever it should be,...


Download the correct XP drivers for the System from Toshiba's website itself. Install all the Toshiba drivers as on some of the notebooks, the monitor panel drivers are actually contained in the video adaptor files & are installed at the same time.

I Have a resolution problem


Did you download the video driver from the Acer WEB site?
The ATI Radeon driver must match the XP or Vista version of Windows that is installed on your ACER.

Screen resolution always get back to a different value


There is most likely a utility ( ati util ) that runs in the background so set the resolution through there utility and that should solve the issue where as if you set it through windows display properties it will continue to do the above.

You definitely have a video driver problem.

Try downloading the latest drivers for that machine from the Acer web site here:

http://www.acerpanam.com/flex/acerdrivers/bin/drivers.html?CFID=4762836&CFTOKEN=44214295

...if you do this (or have done it) and it does not work properly, try reinstalling the operating system and then installing those drivers fresh after install. That should work. If it doesn't, look in the Acer user's manual for the machine's maximum resolution (for example 1024x768), and then changing the video driver to one of the standard Microsoft drivers, for only that resolution. The problem you are having above seems to be that you tried this solution, but loaded a MS driver for the wrong resolution. So you are probably pretty close on it.

Good luck.

No 3d acceleration in Vista on ATI 7500


Well, I'm amazed a C640 runs Vista at all. There's no reason to buy a new hard drive, except for the novenlty of having one loaded with Vista on a C640. It's a great laptop, and runs Windows XP PRo perfectly well. If you have one od the Dell XP install disks, just boot from it, and whenever it finds the vista install, hit excape, then at the next screen hit "D" to delete the partition, then choose "quick format", and load the Operation system. If you need an install disk,let me know. Good luck
