m15 R1, another bunch of HARDWARE bugs

Question

The purchased 1 year warranty expired on October 11, 2020.

I don't know what Dell so busy for, but they kill their game gear department... by the luck of support.

I report a lot of bugs into AWCC/LightFX interface, NONE was fixed in 6 months.

Now a fresh bunch of bugs, this time LightFX hardware related.

1. Funny, but it's about color mixing. Open AWCC, and set color like R128, G64, B64. Are you expect dark red? You wrong, Dell sure it's dark WHITE. It's not AWCC, but hardware bug, many colors shows white shades instead of right tone.

2. It's about hardware interface. If you are use some effects like pulse/morph, it works until next color update. Even if this light not involved into update, effect just stop. So that's why no one use effect in games - any OTHER update stop them. LightFX SDK have this issue as well.

(facepalm. Maybe look for better developers/engineers for you, current one drop you out of market... already close to it).

Jeez, You havin that issue too?

I have it with mine but mine is an older model which literally does the exact opposite colors of what its supposed to be.

Lets say you like red ok? nope, lets give you pink instead? No? How about blue? Sorry we only got green.

I fixed that issue with a CMOS battery disconnect and then I rebooted and reinstalled the command center.

Older models have 4-bit per color, not 8-bit, it's a mess in any case. I reset the system (BTW, instead of remove CMOS, you can just shotdown, remove power cord and wait 10 sec - results are the same), but still like this. Currently i correct colors in my apps by software correction.

That’s really great! I tried your method of turning it off for 10 seconds and then re plugged the power cord but it still had the color not being right so the CMOS was the only way I knew how.

My method is for reboot light system, not to fix this error. But I found the reason. In fact, for PWM-controlled LEDs, you heed to do gamma-correction to have right color. Nor hardware, driver or AWCC(!) don't do it. I implement it in my software, now all colors are correct. PS: If some guys from Dell read it - just as simple as r = r*r>>8, g=g*g>>8, b=b*b>>8 before color set.

Got it, I kept that in notes so I can change the colors properly. I also managed to get white on the X51?

What API version you x51 have?

I have issue with white point at my old 13R2, it have API V2 with 4-bit per color.

Let me check my archive, i found a color looks close to white, share rgb for you if found my old profile.

UPD: Ok, i check. You can't set it directly in AWCC, but use "Polar" scheme as a hint (decrease some blue). You need to modify profile file (it's xml), changing RGB there.
