Yes. Nvidia driver from clevo was installed first, then control center was installed. I also tried official driver from nvdia's website, got the same result.
Adjust Brightness bar doesn't work

PCSPECIALIST don’t monitor the forums, you need to give them a call or web chat to diagnose further

As said, the hot keys are managed by control center which is running within windows, won’t work in the BIOS

If you go into control center and try changing the brightness in control center rather than with hot keys does that do anything?
I've tried that and it still doesn't work unfortunately.

a bit more information i collected which might help with the debugging.
so AIDA64 tells that the Nova has a PANDA LM156LF1F02 screen https://www.panelook.com/LM156LF1F02_Panda_15.5_LCM_parameter_44308.html
first batch from a competitor had AUO B156HAN08.0 screen.
I'm just guessing here, maybe a BIOS or VBIOS update is needed to supported by the panel. I did find a newer BIOS online from https://clevo-computer.com/en/support-drivers/ but i decided not to try it, since it could potentially void the warranty.

okay, an expert told me that it's very likely to be a EDID mismatch issue, which happens quite often when you replace the panel with a different model. there are some DIY fixes available to it involves flashing either flashing EDID of the panel or flashing VBIOS or BIOS. since those fixes would void warranty, i will see what PCS say tomorrow.
just called PCS, very professional support personnel. here in germany they will just ask to repeat driver update / os reinstall even you told them it's already done.
anyhow, their technician will look into that and give a response later. we discussed about BIOS versions over the phone, the one i have 1.07.04 is the latest they got.
just post the 1.07.06 version here just in case the technician looking into thread want to test with it. but be aware it's from a different vendor.

I removed the link, partly because the PCS technicians almost never visit here so he/she is unlikely to see it (if the technician is reading this please PM @nova user directly) but also because there is a danger of someone less technically capable trying to install it and bricking their laptop and/or voiding their warranty. Thanks for understanding.
sure no problem. i did it as customer support also asked for the forum link to send to their technicians to take a look. anyway, PM me for the link if needed.I removed the link, partly because the PCS technicians almost never visit here so he/she is unlikely to see it (if the technician is reading this please PM @nova user directly) but also because there is a danger of someone less technically capable trying to install it and bricking their laptop and/or voiding their warranty.
