ANSWER to your problem is Intel DO NOT! do drivers for win 8 for anything older then the 2nd Gen Core I Processors.....
original Core I HD Graphics (Example) and Below .. all u can do with 8 is use the default drivers windows 8 has which only allow it to basic function .... a few google searches and you ll find lots of people have tryed to Mod the INI files to make it work etc but with limited success....
I have oinly found that the last driver for the original Core I HD Graphics (Example) win 7 driver works on 8 .... anything before that i found either installed but broke the os or installed and never functioned right.
as your saying Gma 4500mhd and Intel 4 Express you ve got Core 2 Duo CPU making it older then Core I
so your TRUE answer to this problem is you either put up with it at wrong res etc in windows 8 or downgrade to windows 7 on that laptop .... (or ultimately buy new laptop!)
