Gary uses a Lenovo Thinkpad and the latest 7th generation laptop doesn't seem as bright as an older 6th gen model. Is that normal? Does going 4K sacrifice brightness or is something wrong? Leo says that due to battery life, laptops never go to full brightness by default. You can look in the BIOS settings for brightness and see if it's set lower. Leo found his set at half. Press F12 on boot to access. Also check the Thinkpad SubReddit. That's a good place to ask.
