ccvortex Posted July 2 Share Posted July 2 Hi all, I am not able to adjust the laptop screen brightness - I have tried the keyboard keys, the mobility center, the display setting, the NVIDIA control panel... nothing I do works. The screen is pegged at 100% and is over saturated, not sure how. Thoughts? DPM 7760, Win 10 Pro, switchable graphics off. Link to comment Share on other sites More sharing options...

What NVIDIA driver are you using? I've heard other mentions before that screen brightness can break if you use the "upstream" driver (i.e. from NVIDIA's web site) rather than the driver from Dell. You can also set the screen brightness in BIOS setup. Clunky but I think it should stick when Windows boots up?

ccvortex Posted July 2 Author Share Posted July 2 I'm using 536.45 but honestly I don't know if this is the DEL signed driver or not... haven't tried the BIOS adjustment yet, can't reboot at the moment. Link to comment Share on other sites More sharing options...
ccvortex Posted July 2 Author Share Posted July 2 BIOS adjustment works, and updated drivers with the Feb 24 ones from DELL's website, still no luck, no brightness adjustments, really weird. Link to comment Share on other sites More sharing options...
heikkuri Posted July 3 Share Posted July 3 I am running version 552.55 directly from NVIDIA and it works with all Dell Precision 7XX0 models. Why just uninstall current driver with DDU and install the driver what you want to use. Sometimes the drivers just stop working or some feature has problems. Reinstallation or upgrade helps. Intel UHD Graphics driver is 31.0.101.5333. Does the resolution change work? Link to comment Share on other sites More sharing options...

ccvortex Posted July 4 Author Share Posted July 4 What's DDU? Res change works, yes. I have no DELL apps or drivers installed that relate to video - no diaplay calibration, nothing. I don't think I have optimus installed. Link to comment Share on other sites More sharing options...
Aaron44126 Posted July 4 Share Posted July 4 DDU is "Display Driver Uninstaller" which is a good tool to remove traces of the NVIDIA / AMD / Intel drivers on your system and start fresh. I have used it many times myself. https://www.wagnardsoft.com/display-driver-uninstaller-ddu- Apple MacBook Pro 16-inch, 2023 (personal) • Dell Precision 7560 (work) • Full specs in spoiler block below Info posts (Windows) — Turbo boost toggle • The problem with Windows 11 • About Windows 10/11 LTSC Spoiler Apple MacBook Pro 16-inch, 2023 (personal) M2 Max 4 efficiency cores 8 performance cores 38-core Apple GPU 96GB LPDDR5-6400 8TB SSD macOS 15 "Sequoia" 16.2" 3456×2234 120 Hz mini-LED ProMotion display Wi-Fi 6E + Bluetooth 5.3 99.6Wh battery 1080p webcam Fingerprint reader Also — iPhone 12 Pro 512GB, Apple Watch Series 8 Dell Precision 7560 (work) Intel Xeon W-11955M ("Tiger Lake") 8×2.6 GHz base, 5.0 GHz turbo, hyperthreading ("Willow Cove") 64GB DDR4-3200 ECC NVIDIA RTX A2000 4GB Storage: 512GB system drive (Micron 2300) 4TB additional storage (Sabrent Rocket Q4) Windows 10 Enterprise LTSC 2021 15.6" 3940×2160 IPS display Intel Wi-Fi AX210 (Wi-Fi 6E + Bluetooth 5.3) 95Wh battery 720p IR webcam Fingerprint reader Previous Dell Precision 7770, 7530, 7510, M4800, M6700 Dell Latitude E6520 Dell Inspiron 1720, 5150 Dell Latitude CPi Link to comment Share on other sites More sharing options...
