Mac Pro 4.1 (circa 2009)
AMD Radeon HD 7950 3072 MB graphics card
I have just connected dual 27" Cinema Displays.
Both work, lots of display space ;-)
Two problems (perhaps related):
- F1 & F2 keys only adjust brightness on the primary display.
- 2nd display about (purely estimated) 92% of the brightness of the primary display and just a bit too dim to feel comfortable. While perhaps just the difference in ages and use of the 2 displays, I wonder if something else might have gone awry?
Any way to adjust brightness of both displays from my keyboard?
Any other adjustment I can make to the brightness of the 2nd display.
