Problem description: I bought a second-hand Sony VAIO All-in-one PC. The monitor's LEDs are cranked up to like a billion loving lumens and it actually hurts to look at. There are no hardware buttons to reduce brightness and the ONLY method offered by Sony is to use Fn+F5. But this second hand machine was sold without a keyboard and how many 3rd party keyboards have loving Fn keys?

Attempted fixes: Sony support is a joke. Also, windows on-screen keyboard has an Fn key, but it doesn't work to change brightness.

Recent changes: N/A

--

Operating system: Win7 64

System specs: Sony VAIO VPCL214FX

Location: US

I have Googled and read the FAQ: Yes. Here's the user manual.

This is what
Arcane Velocity was like.
I looked up key remapping software, but unfortunately Fn combinations are hardware-level and can't be remapped in software. Double unfortunately, I think this means that even third-party keyboards with Fn keys are going to have the wrong Fn mappings (like, there's no guarantee that Fn-F5 from a Lenovo or Apple keyboard will send the same keypress as Fn-F5 on a Sony keyboard).

So you need a Sony keyboard. At least long enough to use a key remapper to see if it can capture the Fn-F5 combination (it may not be able to) so you can set it to a different, more sane keystroke to do the same thing.

Hate to sound sleazy
But tease me
I don't want it if it's that easy
If you have the right drivers installed, Windows should put a brightness slider at the bottom of your Power Options screen

Well, I found a solution, but first, gently caress Sony for designing something this stupid. So as I said, the on-screen menu does not provide any picture or brightness adjustment while in PC mode. But it does have HDMI input, and while in monitor mode suddenly on-screen controls appear! Since the computer also has HDMI output, a $6 patch cable later and...


Seriously a person shouldn't have to jump through that many hoops for something so simple.
