Hello,
As the title states, I encounter a problem with my Windows 7.
Here are listed categories, and their inside stuff:



ABOUT THE PC

PC: Windows 7 Ultimate (with SP1)
System type: 64 bits (x64)
Processor: Intel(R) Core(TM) i3 CPU M350 @ 2.27 GHz 2.27 GHz
RAM: 4GB
Graphic Card (Normally): ATI Mobility Radeon HD 5470 | Graphics 512MB
Activated: Yes


ABOUT WHAT HAPPENED BEFORE THE PROBLEM

My PC had, as a graphic driver, something called "VGA". This, is not the graphic card installed on my laptop (physically) at all. So, I went to the original AMD drivers website, and I downloaded the graphic card driver for ATI Mobility Radeon HD 5470. Now that I installed it, when I boot my PC, the screen is black... or seems to be. If I focus enough and put my head on the screen, along with a pocket lamp, I can see a little bit the screen.


WHAT I TRIED TO DO

I tried firstly to go search for luminosity in control panel, and it's maxed out.
Then, I uninstalled the driver. Works, but I am stuck with VGA again. So, second installation of the driver, again.
I thought that perhaps if I use an HDMI cable and try to show my laptop's screen on the TV, it will actually work. Guess what? It works. So, here I am, asking help, with my TV as a screen.



WHAT I AM ASKING FOR HELP FOR

I, please, ask of any one of you looking at this text, to please find a solution to this problem. I need to use the AMD driver, without having a very dark screen. Isn't there any software for exemple, that could artificially put the luminosity level to 200% or anything like that?
Thanks for reading.
Regards,
-Laiks.

P.S.: Yes, I know it's a potato PC, but it actually is pretty strong with the AMD graphic driver only.

I've guessed it would be looking normal, as the screen, i can see it clearly with the TV, and I can see it a little bit by bending my head towards the screen(of the laptop).
Here, that's a screen picture.

Use a phone to take a picture of the problem, what you got is just a screenshot that doesn't help

Isn't that violating my privacy?
Oh well.

First one is my laptop.
Second one is my TV.

You asks for help, so don't complain about it. Looks like laptop screen is dead even though laptop turn on.
That's not called complaining bruh, and laptop screen isn't dead, at least I think, as I can still see the laptop's screen if I use a lamp.

Look for the function key that controls your back light (normally on your numbers at the top) and press that with the function key at same time.

If it does not come back on your light is dead and will need replaced.

I guess it would be Fn + F6 as this will increase the screen's luminosity, because theres a picture of a big sun in a rectangle, and it's blue, like the Fn key. But, unfortunately, that doesn't work.
Edit: I just understood something new. When I click on Fn + F6, it does increase my luminosity, as when I go in control panel to see, it works, but it looks like the luminosity increasing or not is not affecting the real "luminosity". When I decrease the luminosity, either with Fn + F5 or with the luminosity bar, nothing changes (at least on the TV's screen). perhaps it does not affect the value of the luminosity.

Let's get a few things sorted out first.

A backlight is a small light source behind the screen that illuminates the pixels, that is correct. The brightness controls on your laptop generally only control the brightness of the built in screen, never an external one. "VGA" in your laptop stands for Video Graphics Adapter and is just the generic default driver, nothing bad but also nothing special.

Am I correct in assuming that the screen has worked normally, meaning it actually glows and is visible normally, before you installed the driver manually?
If so, where did you download the driver from? Did you download it from AMD (since they own ATI now) or did you download it from the manufacturer of your laptop?
If you didn't download the driver from your manufacturer, uninstall it and install the one from whoever made your laptop instead. Even if the driver version is older, that download will potentially contain a few things that are specifically needed for that laptop that AMD / ATI don't offer bundled.

Yes, you are right, the screen worked normally before I installed manually the driver. I downloaded the driver from AMD website, not my manufacturer. If I had to guess, with my little knowledge, I think ASUS is my laptop's manufacturer. Thank you, I will try installing a ATI driver from ASUS's website, if it does exists. I will update you, thanks yet again.

Very likely, if you aren't sure you could make a few photos of the stickers on the backside of the laptop. There you should find who made it and what model it is. Be sure to grab the driver for the correct model, the driver for other models it might not work correctly either.
