I went to the display settings and it says the recommended resolution is 1280 x 1024 so I tried setting it to that resolution and that brought up that dark blue screen! I changed the resolution to 1152 x 864 on my HPvp17 monitor. That's the resolution I'm staying at.
So far I've been having a really good experience with Windows 7 Beta 1. I never use Internet Explorer because it takes some time to switch between tabs or open new tabs but now Internet Explorer seems faster and it loads/opens new tabs faster as well! I copied all my documents from my flash drive to my computer and it took some seconds for everything to be copied. That was really fast. I viewed pictures from my SD card and the image previews of each image loaded noticeabley faster as well.
Compared to Windows Vista Business Edition/Premium Edition, I would say that Windows 7 Beta 1 is WAY better! (at least from the experience I've had with it so far)
I'm going to install Microsoft Office 2007 Professional, Adobe Photoshop CS4, Firefox, Google Chrome and see how it goes.
