Dell P1110 brightness problem February 20, 2006Posted by oktyabr in hacking, hardware, personal.
I caught a classified add in my local paper that listed “Dell 21″ monitor for sale: $50″ A 21”?!?!?! w00t! I went over to check it out and fell in love! In fact I told the gentleman that if he had more of them I would probably buy two or three.. “I do have more.” he replied. My heart start beating harder and I forgot how to breath as schemes of how to convince my wife that I needed not one “new” monitor but several started bubbling in my head. 15 minutes later I left with two of them and a $90 hole in my wallet where some of my LCD money used to be.
They are gov surplus (I live in a fairly high-tech area), vintage 2000, so they have seen lots of use, I’m sure. The pictures are still nice and crisp and they pull off 1600×1200 @85hz with no problem (3200×1200 in twinview! Yipeee!) but i DID notice that really “black” blacks were tough to get with them, even with brightness turned all the way down. Usuable, but far from what manufacturer’s specs were, I’m sure. I posted in the Tech Talk section of one of my favorite BBSs and got the following reply from one of my friends:
The P1110 is a great monitor, but you will run into a problem, but it is easy to fix.
At some point you may start to notice that it takes 10 minutes or more to go from blank screen to being able to see a picture. This has to do with a faulty heat regulator. I’ll try and find the link on how to fix it.
Another problem you may encounter is that it is too bright. You can find a way to fix that here: http://www.hutzelman.com/home/hardware/mods/monitor/
So it’s off to http://www.hutzelman.com/home/hardware/mods/monitor/ I go… nice HOWTO with lots of detailed photos. Doesn’t look too difficult… just requires replacing a single resistor (in each monitor) that controls black levels. Time to go find a soddering iron 😉
