Hi to everybody. Some days ago, with the help of "Ken", I had discovered that this monitors (and many others manufactured by Dell, HP, IBM, Compaq, with the same "Sony-Trinitron" tube) are affected by a problem, also know as "Overbright" or "washed colours". There are two solutions: the first one (that is the solution that I have adopted this evening) is very simple: changing only a resistor. The second one, a little more complex, is based on a software and requires a reflashing of the eeprom of the monitor.
I have tried (because is very simple, and inexpensive, only 10 Eurocents) the first. I have changed a resistor from 10 Mohm to 6,8 Mohm. See this link:
This is the first, simp,e solutions. Results: good. The monitor appear with correct colours, black in "black" and not grey washed. I have some problems with the geometry of the screen and the convergence..but I think that is a problem of my monitor.
Coming soon: the second solution, based on reflashing of the eeprom.
