So I just updated my laptop graphic card driver. My laptop is a Dell XPS M1530, with Nvidia Geforce M8600 GT graphic card. Yes, I know it's old (almost 5-6 years old already IIRC). However, I have my own desktop to play game at home, and I only use my laptop for work and playing when I'm oversea on work trip (and can't play on my desktop). For that purpose it's working very smoothly so I don't feel any need to replace it anytime soon.
As 5.4 is coming, I want to prepare my laptop in case I have any work trip coming that may affect my raid schedule. While doing my normal maintenance routine, I think it would be nice to update my laptop graphic driver (as the last time I updated it was ~2010). I downloaded and updated it. The updating process ran smoothly and my wow's fps on laptop seems to improve a little bit. However, my fullscreen (in WoW only) isn't really fullscreen anymore. I'm running 1024x768 resolution on my laptop (although it's support 1400x900) since that give me a playable FPS during 25m raid (~7-10fps, a bit spiky but it was fine for me). Before the update, my WoW screen span to whole screen, even at 1024x768. However, after the update, if I use 1024x768 on fullscreen mode, there are black bars on the side making me wonders if this 1024x768 cover as much as it did before. If I set it on 1400x900, or 1024x768 using "windows (fullscreen) mode", it will again span to the whole screen, but both option would (I guess) lower my FPS so I don't really want to do that.
Is there anything I can do to make my 1024x768 Fullscreen mode to span to fullscreen again?
Thank you much in advance.
