8770W Screen panel broken, need replacement

Hello everyone, glad to be in a forum with multiple conversations about the 8770w.
On my 8770w laptop the screen is broken.
I have opened and had the model: LP173WF1 TL B5
I bought a compatible model: N173HGE L11
I have assembled it and I do not like to see. It seems somewhat dark. The brightness adjustment to the maximum but I do not like to see.
What is happening here? The compatible panel are not good?
Should I go to another option?
My screen frame has a DreamColor sticker
What does that mean? the broken screen is not DreamColor I think.
Maybe in the past?
Can I then add a DreamColor screen here?

 

If you shine a flashlight on the panel do you see any display at all that way?

 

[QUOTE = "Vaardu, post: 11040181, member: 683461"] Si enciende una linterna en el panel, ¿ve alguna pantalla de esa manera? [/ QUOTE]
If there is light on the screen, but the previous one was brighter, more vivid, now it is as if I am wearing sunglasses.

 

I think the 8770w's DreamColor panel is from the LP173WF3 family. Does the cable go directly in the display or goes through another PCB mounted on the display frame?

 

The cable goes directly to the panel, there is no intermediate circuit.
So it is not Dreamcolor.
I can add DC for an interesting price:

I have installed the AMD Radeon application and accessed additional settings. Now the screen N173HGE L11 looks great
