EDIT for clarity:
While resolving the problem via my GPU's configuration interface does work to a degree, it won't make the problem go away. There are a ton of people out there of whom it's too much to ask to configure their graphics card, much less their monitor lighting, so please don't suggest that as solution

So, I bought the Ebonheart Mansion on PTS, fully decorated, and upon walking in, I face this:

I felt half-tempted to put up a few Ancestor Shrines, if I could have found them in the Crown Store, just to match the overall feel of the place.
In comparison, this is Hrogar's Hold, sharing the same floor plan. There are even _less_ light sources, yet the place is far better lit:

This is the Velothi Reverie, the house that my character and her husband will move in for real:

There are 9 light sources (excluding the fire) on that part of the image that you can see. I have spent 10% of my furniture limit (Yes, ESO+) on light sources, and I still find the place too dark.
This is Neron Arona's House, sharing the same floor plan minus the extra rooms:

There are three light sources on that part of the image that you can see, one of those being a randomly placed lorebook.
Please, can you give the in-house lighting a bit more Magnus? It's probably Meridia, sucking half of it off on the way through the Coloured Rooms, but unlike her, I'm
a paying customer a living person, I need the light far more!
