Milossek: If your is brightness too high you can change reduce the value of R457 or R459 on the board mounted around the CRT base but you must use high voltage resistors 1KV plus rating, or increase the chip resistor R463 which is 100K. Because I have 6M8 1.6KV rated resistors in stock I have found that changing either R457 or R459 to 6M8 from 10M is usually enough to bring the brightness back into spec.
This change will not affect the operation of the DAS software should you have it set up at a later date.
one other thing to check on this first is the heater voltage according to the manual the heater volts on this beast is only 4.7V not the usual 6.3
Just a note to thank you guys for the info, particularly Richard.
I just bought a Dell P1110 used. It had the brightness problem in a big way and I had to use an nVidia software adjustment as well as having the front control on zero. Even then it didn't look much.
I tried a 6M8 in place of R459 (10M). That one is easy to get to right at the back of the monitor after removing the plastic cover and two metal ones.
The 6M8 made a huge improvement. I could remove the software adjustment but still had to have the front control on zero.
Next I tried a 4M7 which was recommended on another forum. With the 4M7 I was using the front brightness at 70-100. This was okay but PowerDVD XP was rather dull even at 100. (PowerDVD has the same low-level problem with its audio.)
Today I tried a 5M6, it seems to be perfect so far. I bought a 2M pot to use with the 4M7 just in case it didn't work but there's no need. Now I'm running the brightness about 40-50. Best of all the (1W) resistors cost AU$0.22 each. ':^)
I still run the contrast at 90-100 but that's me on any monitor anyway.
There is a slight ghosting, about 1mm to the right. The two focus adjustments have no effect on this. It only really shows with black text on a white background.
