DELL P1110 monitor too bright

Ivan

You have been doing the "Auto Color calibration" after you tried each resistor, right? If not, you could get funky stuff like that.

The monitor was pretty messed brightness/contrast wise after I performed the mod until I did this.

How do you do that? If it's what I think it is, then it might have been the thing that messed it up.

More details on my funky brightness controls. When you turn it up from 0 to 30 it gets brighter, then after that, the more you turn it up the darker it gets.

Any help would be appreciated.

Well, because I dont have the monitor in front of me this moment, tell me what you did to mess it up, and I'll tell you if that's what I was talking about. ;)

Went into the menu, and did the "Color Return??" option.

Is this the same thing you did?

The higher the resistance, the brighter the picture.

are you SURE?

i heard it was just the opposite in regards to making this modification

i was told to try 4.7M first, and if that doesn't make it dark enough THEN to try 6.2 (or 6.8M)

i decided to skip 4.7 and go right to 6.2 though since my monitor was so bright i couldn't imagine it being too dark, i wanted "maximum brightness reduction"

i don't claim to know anything for sure myself though! i would be interested in an explanation as to what's what & why it works that way

i just tried that too

my screen went black for about a minute, then came back

scared the sh*t out of me!

is that the "AUTO COLOR CALIBRATION" thing?? or how do you do that?

thanks!

To use the auto color calibration thing, you need to have the monitor powered up (and not let it go into power save mode) for about an hour. You'll know it's warmed up, because once it's happy with it's “warmth” will it let you even select the option.

At which point, you can select the option, press (what I recall to be) the right arrow button, and the monitor will go black, and slowly (over the course of 10 seconds or so) fade to white. Then the picture will return (with a better color/brightness/contrast calibration) but you will still have to set the levels themselves, this only calibrates the scale.

thanks but....

my moniitor doesn't have an option to do that anywhere....i've searched all of the menus

i have a DELL P1110 / trinitron

When i got my hyundai L70S it was way to bright but my eyes got used to it :D

You sure? Check Color/sRGB tab/ and select "Color Return". Keep in mind it may say "Available after warmup", and be unselectable untill the message goes away.

Jameco can source and supply milspec resistors (look for those with 5% variance or less, in the commercial catalog, and NOT the home catalog). As to where Navy Electro(nics) Tech got his at work, um, milspec supplier I would guess....

So anyone have any insight on why my brightness controls are all messed up?
When you increase it from 0 to 30 it gets brighter, but if you increase it after that, it actually gets darker.

I'm really confused. I'm wondering if I burned out the resistor with heat when I was soldering it on.

stratacat

Go to control panel then adobe gamma load a different monitor profile i am using the canon hdtv gamma 1.5 monitor phosphors (trinitron) check the single gamma only box desired Macintosh default 1.80 white point hardware 6500 k daylight
ADJUSTED SAME AS HARDWARE I'M USING THE SAME MONITOR AND NOW MY BLACKS ARE BLACK INSTEAD OF WASHED OUT GRAY !!!! HOPE THIS HELPS YA OUT !

right! i did do that b4, under the "EASY" color submenu

i just tried it with the RGB menu as well

i didn't realize that was what you meant by "AUTO COLOR CALIBRATION"


now here's a new perplexing thing

when i just went to do that under the "RGB" setting, now my monitor is really "faded".....it looks terrible....no brightness or color adjustments seem to help either


but i can go into the "COLOR" menus, and switch it to "EASY" instead of "RGB" & it looks alot better

also tried the 3 settings there, 9300, 6500, and 5000, and 9300 looks "best" but not great

i don't know what any of this stuff means but think i learned something - that there is alot more to this than i realized....

Hello, I found this thread to be very helpful as I too have this monitor. I dont have a problem with it being too bright. My problem is that I get a shadow to the right of everything on screen. It is not the Convergence settings because the shadow has no color. Is there a controller inside the monitor that will adjust this? Or is this some signs of old age which can not be repaired? Also, how do I remove the cover from the back of the monitor. Thanks for your help :)

Unless you know what you are doing, removing the cover of a monitor can be extremely dangerous. Monitors are not like a typical household appliance (including the computer itself), even unplugged there is enough stored voltage in there to kill you.

The shadow problem sounds like it could be interference from a power cable or a speaker. Try moving anything electrical or magnetic which is near your monitor and see if the shadow disappears or moves. :wave:

I am a new owner of a pre-owned Dell P1110 monitor. I picked it up from the trash pile at a friend's company. It had the brightness problem. I performed the resistor hack. I went to Radio Shack, and picked up a 100-pack assortment of cabon film resistors. In that package, was 5 1-megaohm resistors. I soldered them all in series to create 5 megaohms, and soldered it in. And now the monitor is good as new!!!!!! Thanks to all who have provided information on this.

On the note of your shadows, I also am getting shadows to the right of every dark contrast line. The reason this happens is because this particular monitor is very sensitive to interference. If you are using a poor quality cable (as I am, its a $20 best buy cheap cable), the ghosting is typical. Buying a high quality cable, I am told, will solve this problem. Here is the cable that I just ordered which I hope will solve the problem:

http://www.pccables.com/cgi-bin/orders6.cgi?action=Showitem&id=ID1811422&partno=00646&search=MONITOR&rsite=pccables.com&rcode=

That is PCCables part number 00646, 10FT. SVGA CABLE MONITOR HDDB15 M-M, $6.45. I will keep posted how this cable works for me when it arrives in the next few days.

great infomation partipilo. I hope this cable works for me too. :)

That monitor cable worked! No more ghosting! Wheee!!~

mine was shipped out today. I hope i have the same results.

The higher the resistance, the brighter the picture.

I am going to try getting a 10 MOhm pot. (variable resistor) That way,
I can fine-tune it and also readjust later if the screen degrades again.

I will let you know what happens.

Dan

Element

The shadow is gone!! thanks for the tip. :D

I ended up just using a 5.1 MOhm resistor instead of the POT. BTW, I could
have gotten the same result by leaving in the existing resistor and soldering
in another 10 MOhm resistor in parallel, givinig a total resistance of 5 MOhm.

Flyingpolarbear

I was about to open up the case and change the resistor, when I came across a much simpler fix for the washed-out appearance on my Dell P991 Trinitron.

Go into the Option Menu and activate the Color Return feature (available after the monitor has warmed up).

This will recalibrate the grey levels and fix the brightness.

Before, I had to turn it down to 0 brightness. Now it's perfect at level 50.

No need to risk being fried by human bug zapper or obtain fancy service software.

One killer on this monitor is the convergence. How the hell do you set it up perfectly? I just can't seem to set it up perfectly :(
