An engineer friend of mine called me a couple weeks back and asked me if i was still interested in his Dell P1110 21" monitor, he said he doesn't bother with it anymore. I wasn't in town then, i went and picked it up now. I paid him $24 for the beast.
It has the classic overbrightness problem common to this series, in this case it's as bad as it gets, retrace lines visible at zero brightness. In these monitors, there is no G2 (screen) adjust knob on the flyback, it's all MCU controlled. All you get is two focus knobs. Fortunately the fix is known, these monitors have a TTL port at the back, and a serial port (RS232) to TTL cable together with the WinDAS software can be used to adjust ALL parameters of the monitor, G2 voltage included. I have already built the cable using a MAX232 converter IC and i've had the software around for several years.
The guy didn't have a spare VGA cable and neither have i, so it'll have to wait until tomorrow. In the meantime, i'll give it a good cleaning. I'll be giving away my good ole' Nokia 920C (19") to a friend of mine who still runs a 15". The Nokia is a great monitor, i only paid like $12 for it 4 years ago, and all it needed was a good calibration, but the curved screen and ABL issues (contrast limiting when transitioning from dark to bright) have kinda gotten on my nerves. The Dell P1130 is 21" worth of flat, anti-glare goodness.
