Change Brightness Windows 7 Laptop

..first 24 hours..used only 7%..couldn't ask for anything better...

Great that you can change the brightness as-well as colour temperature.

I love my laptop, its fast and works great. My desktop is Windows 7 pro and this comes with windows 8.1 home. I just need to upgrade it to pro and I'm good to go.

7 frames/second with 18b battery. Lightweight. No cons so far.

overall, this projector is incredible. the picture is wonderful, the colors are vibrant, even in the day with the windows open. the brightness is like nothing i've ever seen. i agree with one other reviewer that samsung absolutely needs to have a brightness setting for the night. with all the lights off it's actually too bright. i was able to get around this by using netflix, hulu, etc. through my computer and adjust it that way. however, it would be much easier if the projector itself could do this. despite the brightness, i didn't notice any rainbow effect. wonderful product overall.

Exceptional brightness and color even during daylight in a room with four large windows with blinds. At night the screen completely illuminates the room. Better light quality than I have seen from OLED ... mini-LED was the best choice for us. The 4K UHD on this size of screen is simply incredible.

I *thought* this was an HDR monitor because the Dell website listed it as Ultra High Definition in the list of monitors when I filtered for that feature...however it is not. Initially I was really upset and felt that I wasted my money. B&H really tried hard to help any way they could, but their site clearly says that it's not an HDR monitor in the detail specs tab, but I didn't look there because Dell already said it was. BUT, after using the monitor for a few weeks now, I really, REALLY love this monitor! It's soooooo big, and beautiful with awesome color depth. If you download the Dell monitor software, you can even schedule the brightness and contrast to change according to the time of day (looks like there is 2 settings: day and night...but you might be able to do more detailed scheduling). It even allows for transitions between the two settings so they gradually take effect over, say, an hour (or whatever you want.) I'm usually working with lower ambient lighting in the evening hours, so this is a fun feature to play with. I do wish it had an ambient light sensor to change the brightness automatically, but that's okay. You can even have it automatically dim the screen when your screensaver is going, to save on energy. There's also some great screen sectioning capabilities to split your screen up into multiple zones that you can dock your windows into. Since the monitor is so big, I find it rare for me to ever want to have a window full screen, so this is a great feature as well. Overall, I'm super happy with the quality of this monitor!!! Yes, I'm disappointed that I still cannot edit my photos in HDR, but I don't regret this purchase because it's definitely better than what I had before!

Quick set up, useful stand options, easy to change warmth and brightness

Worked great with my Windows 10 laptop. I did not need to use the Driver DVD.

It's great laptop ready to use but more power with probably a Windows Pro edition.
