You will probably need to wait till Avast decides to make a change. It is their product not a windows
specific screen.
Since I hardly ever open the UI, it doesn’t bother me at all.
The fact that the protection has gotten better is what does excite me. 
You need to read the first post (and my Reply #2 to see what he is trying to achieve) Bob as this has nothing to do with avast 8.
Don’t have an answer yet but am working on it.
Better make it ASAP Bob because I can’t keep on wearing sun glasses all the time when I’m using the s**t-less W8 8) 8) 8)
Bloody MS why are they so dumb.
Did you try lowering the brightness Speedy? 45% for plugged in and 35% for battery works well for me, they are extremely bright screens on these Asus G model laptops and if you don’t drop the brightness you’ll end up what your experiencing now ( fried eye balls ) and headaches.
Would you be kind enough to show the correct direction otherwise all my brightness are control by NVIDIA Control Panel not the OS, it get very tricky to control the brightness from a laptop as I had more control from my own VGA desktop machine I hope you understand what I’m saying as I’m not giving up my new laptop.
The problem with adjusting your brightness, to get it to an acceptable level everything else becomes too dark. My desktop TFT is 35% brightness and 90% contrast and it is still too damn bright and totally lacking in contrast.
I just wanted to change the pain in the bare arse whiting background in a soft grey will nearly solve about 70% of my problem because I wear glasses 8), and I cannot bloody believe it that MS took away that feature as DavidR post before and now I know why MS are becoming a bloody dick head in the W8 OS.
Go to control Panel/ Power Options/ Change Plan Settings.
I also don’t use the NVidia colour settings, I’ve left all those at default which is to let other applications control all that stuff.
My contrast is 100% (Default) which is why everything still stays nice and clear and still easy to read at lower brightness settings on these LED screens.
Even at 100% contrast this UI is still washed out and totally lacking in contrast…
I didn’t realise this topic had now become a UI contrast topic 
it could be the difference between your TFT screen and the LED screens.
Craigb you’re settings is not to bad it almost close to where I want it, only IF I had that last bloody wish I need that whiting background option as I discuss before MS didn’t include this option into W8 and my problem would been solved. I wish I had my bastard double barrel 12 gauge shotgun to shoot MS for been a bloody dick head, boy these poeple are really pi$$ me right off for W8 >:( As I said I’m not giving up my loveable G75Vx laptop.
Well Microsoft didn’t include that setting within win7 either, it’ll just take time for someone to come up with a third party app for win8 like they built for win7.
You are 100% right this bastard is one angry powerful G model laptops :o :o :o :o :o :o :o
I don’t how you keep up with this bloody monster I reckon you’ve got more balls than me ;D
Keeping up with it isn’t the problem, it’s lugging it around that’ll kill you ;D
Ha ha ha Rambo ;D

I put the question to Vishal and this is what he suggested:
http://www.askvg.com/how-to-access-advanced-appearance-settings-option-to-change-text-size-in-windows-8/
You’ll need to use the registry section of this tip to access these features.
Back up your registry before making any changes.
Good luck
I’ve thought about this option Bob however I’m not going to scratch W8 if you understand what I’m saying, I may have to wait until a 3rd party software becomes available for W8 as Craigb said because I have no other choice to sit tight and wait.
Thanks for trying Bob just keep an eye out for the 3rd party tool for W8 this could solve many issue and who knows, I hope MS hasn’t pi$$ you off for something is missing on you’re OS :
WindowBlinds from Stardock might have what your after Speedy, there is a trial version free for 30 days you could test first as it doesn’t mention win8 as of yet.
If you scroll to the bottom under features, the top right picture does mention changing the backgrounds of explorer windows.
