If you get the FHD model, be aware that it has content adaptive brightness control (CABC) that can't be turned off. And Dell has so far refused to fix the issue. Extremely annoying if you're working with dark terminal screens and regularly tabbing into brighter windows.

- antongribok 9y agoThis has gotten a major tweak with a 2.x BIOS update, and it's a lot better now (IMHO). It's still there, but barely noticeable. Also, now the minimum brightness setting is now super low, which is kind of refreshing actually. Personally I like it, but I can see how some might not.
- Tharre 9y agoThat's odd, do you per chance remember which update exactly? The CABC is implemented in the Novatek display driver IC, which the BIOS never touches. Dell provides a utility for Windows for flashing it on supported systems (QHD or the similar Latitude 7370) from Novatek for precisely that reason. Though the brightness settings might make a difference.
- antongribok 9y agoI do not, which is why I deliberately said "2.x". I think it was either 2.1.x or 2.2.x, but not certain. I'm not sure why you would think the BIOS update package would not touch it. It certainly touches the USB-C and the TPM modules. It was around the end of this past summer when that update came out. Along with a different brightness curve, it bumped up the battery life as well. I've heard of the Windows utility for disabling this, but I thought it could be used on the FHD model as well. It didn't bug me enough to bother with Windows.
