Updating ati graphics
While you are downloading that, you need to uninstall Catalyst Control Center (go to the list of programs installed, double click "AMD Catayst Install Manager, click next, and choose the first option, then select that you want to uninstall CCC), well now open Catalyst 12.8 (or 12.9) installer, and install CCC (and only CCC, uncheck anything else). I've worked with Dells for many years, and was a Warranty Field tech for a couple of years, now in a corporate Dell environment. When Win comes back, see if the AMD installer will allow to extract files.I've seen this happen in laptops, and the best solution I've seen is to uninstall all current drivers - AMD and Intel. If so, go through device manager and install the drivers.Although, we have some reports claiming there are issues after deploying a fresh build.Windows 10 has been released in its final form at the end of July 2015, but there are millions out there who are already trying out fresh builds after builds.This means the screen may look a bit fuzzy or have big black lines on the side of the screen.If this has happened to you then fear not, you can quickly fix the issue by following the guide below. enter in "devmgmt.msc" (without the quotes) then click Ok.This early access driver is being provided for users who have had issues launching a small number of Direct X 9 based games.This alpha driver has not been fully tested by AMD and is not recommended for general use.
As for the Intel card, the 32-bit package for Windows 8 is compatible with Windows 7 as well." So, the driver and the CCC application that I had to install were those modified by HP (downloaded from here).
Click on the Display Adapters options then your graphics card for example "ATI Radeon 3000/4000" Right-Click on your display adapter and choose "Properties" Then select the "Driver" tab and choose "Roll Back Driver" This will fix the immediate issue and you can now make use of your wonderful dual screen setup. To prevent it happening again download and install the Windows Update Show Hide tool (WUSHOWHIDE) from here the Direct Link or the webpage.
Choose "Hide updates" Put a tick next to the ATI graphics driver and click Next to finish the process.
What was happening when running the packages from AMD like the one mentioned in the question was that some files were un-packed in where different packages are stored and it installed something - maybe the same - with the same result.) Now I can see that its name looks a bit different than in the initial question: AMD Radeon HD 7400M series.
AMD does no onger support Switchable Graphics (because they no longer use that system, they now use "Dual Graphics", two VGAs working as if they were one) to have the Switchable Graphics again, and your card updated too, you need to download the latest beta drivers (make sure that it says "mobility", if you install desktop drivers you'll screw up), install everything, and then, you have to download Catalyst Mobility 12.8 or 12.9.
Leshcat gets the latest AMD and Intel GPU drivers and does the bridge between them.
