Help! M6500 Display is CRAAAAZY.

Hi. This is my 3rd Dell M6500 laptop, standard display, FX3800 graphics card. The 1st one was a refurb w/ some bad color/gradation issues (not displaying full range). They sent a new graphics card. Didn't fix it. They sent a different refurb. This one didn't have the color range issue, but instead was displaying CRAZY bright colors (particularly cyan/red/magenta/orange), looking way too saturated. They then replaced ALL internal components, including display, and the issue is still there. So they replace that unit with a COMPLETELY new one...guess what? SAME issue as the previous one w/ crazy saturated colors. No amount of tweaking the display settings seems to help it at all. Help? Anyone?

 

Does it have the RGBLED screen? I feel like I recall that one having a higher gamut than standard laptops, maybe even 100%, which would result in "oversaturated" colors.

 

If it's a RGB LED screen, perhaps it's a digital vibrance issue like Bokeh had here. I've also been told that those used to a "regular" TN screen will pretty much always find a wide-gamut one oversaturated, because they're too used to the "dull" colors of a regular screen. There is also Bokeh's post here that lists the steps you should take step by step to possibly solve the situation.

 

I didn't order the RGB LED display, and after reading those threads, thought they might have snuck one in by mistake...but when I go to display properties, it just says Generic PnP Monitor. ....but it certainly sounds like the issue is similar (I just don't have that fancier display)...
help!?

 

The display properties won't show whether it's the RGB LED screen or not. I'm not sure how to tell.

 

If you must:
Documentation

Follow the guide if you feel capable and remove the LCD. Check the model, and look to see if it's RGB LED or standard LED.

 

I'm not confident enough to disassemble the unit...I'm hoping Dell can tell me if it shipped w/ that display (I doubt it would have cause I didn't pay the extra $300 for it)...If it IS a standard display, any fixes?

 

AH. Just found out from Dell they DID send me the RGB LED display (why, I don't know). So it looks like the posted work arounds should work...Can anyone put them in laymans terms?

 

Go to Nvidia Control panel head over the Adjust Desktop Color Settings: select Use Nvidia Settings.
Manipulate Digital Vibrance to allow for less saturated colors.

Kelvin is the color temperature. Typically you want to get as close to 6500k temperature color for the most accurate color reproduction. 6500k=white light.
He is using a colorimeter to measure the screens temperature color, just ignore it as you do not have a way to do hardware calibration.
Gamma is the linear luminance on the RGB spectrum, if my definition is correct. The target for accurate color reproduction is 1:2.2 or simply put 2.2.
Once again just ignore that bit, as you need hardware calibration to get accurate measurements.

 

TheZoid posted color profiles in the main m6500 thread. we made seperate lg and samsung curves. i posted instructions on how to use them. Getting stuff ready for the holidays, so i can't dig them out. I think we posted the color profiles in late April. Most color stuff would be Jan and Feb.
