    Great, the registry hack for the brightness worked a treat. Thanks :)

    I've also managed to re-install the older Intel HD 4000 drivers so everything now works as it was. Phew!

    Another question on graphics, sort of related to my previous one about a 4k monitor - I can go into custom resolutions on the HD graphics but when I try to use a 4k resolution, even at 24/25Hz i get an error message that it's outside the maximum allowable, even though I thought it should be able to drive 4k at a lower refresh rate. Does anyone have a set of width/height/refresh which works?

    Alternatively, should i be using the AMD graphics and, if so, how?

    Thanks

    John pointed me to previous posts (#5944 to #5946) which showed that forum member "Brink" was running NP780 at 4k. Brink hasn't been on here since 2018 so i can't ask him how he did it, hence my post about what do i input as a custom resolution.

    I accept the limitation of a lower refresh rate (due to bandwidth on HDMI 1.4) but both Intel HD 4000 and AMD Radeon 8800 should be able to display 4k resolution according to their specs. I just want to be able to do that.

    I would try to both lower resolution and reduce color depth

    Hello,
    I apologize, I don't know much English so I use google's help.
    Recently, I bought a Samsung from the local market with the following motherboard: Samsung BA92-14180 Ativ Book 8 870Z. Apart from the battery, it is complete. The problem is that it doesn't start, meaning it stays frozen on the Samsung lgo. If I press f2 etc, "please wait" appears in the right corner and it stays that way no matter how long I wait. I disassembled everything, I replaced the RAM, HDD, etc., it still doesn't work. Besides the fact that the battery is missing, I noticed that one of the slots is not occupied by anything. Can anyone help me find out what was connected there?
    Thank you !

    The place on the motherboard I was talking about :

    Sorry, double post !


    And if I was still wrong with the double post, complete here.
    I tried everything I found on the internet, I never managed to get into the bios, I couldn't get past the samsung logo. I disassembled absolutely everything, I started it without certain components, in vain.
    The only weird thing is that free slot in which I didn't find anything when I disassembled it.
    Be careful, it's not the one on the battery.
    I think it's a motherboard problem or corrupt bios.

    Maybe emergency flash of bios though USB?
