I installed windows 8.1 on my netbook, acer aspire one ao531h-0bk which has a highest resolution of 1024x600. However I went to Screen resolution settings and I noticed that the resolution was 800x600. I have the option to change it from 640x480 to 800x600, but 1024x600 is not available. How can I fix it? In both Ubuntu and windows 7, which I have installed, have their resolution on 1024x600 by default, so don't tell me that my netbook doen't support that resolution.

Most screen resolution issues on laptop computers are due to the video driver.
For the ACER Aspire One AO531h, Acer official support only provides drivers for Windows XP and Windows 7, so I would recommend you to try the official Intel driver for Windows 8. Just download and install the Intel Driver Update Utility, it will detect your hardware and will let you install the latest version of the specific driver you need.

It didn't find any drivers. Plus that it run on fullscreen, and it didn't fit properly in 800x600. Should I download the driver manually? My video card is an intel 945GMA. I searced and found some sollutions from registry, should I try them? Jul 9, 2015 at 8:18

Looks like Intel does not provide support for Windows 8... The Mobile Intel 945GM Express Chipset Family download page only provides drivers for up to Windows 7. I've found a guide on How to install intel display drivers in Windows 8, but it does not work with Windows 8.1.– WayfarerJul 9, 2015 at 9:05

If you are willing to make experiments, I'd try to download and install the Windows 10 Insider Preview ISO to see if it fully supports the 945GMA.– WayfarerJul 9, 2015 at 9:09

Er, I already have this netbook triple booted and things started to get complicated. Also I don't have much HDD space. Here, answers.microsoft.com/en-us/windows/forum/… is this solution whith registry, should I try it? Jul 9, 2015 at 10:25

Go ahead... but remember to make a backup copy of the registry key before modifying it. I've found a tutorial that also may help you: How To: Install "legacy" Intel HD Graphics drivers on Windows 8. It works by modifying the Windows 7 driver .inf file to allow it to be installed in Windows 8. It's tricky, but it may work.– WayfarerJul 9, 2015 at 10:33
I just updated the software on windows and it installed a driver which supports 1024x600, and the system is faster
