I've got a bit of a problem...

I'd like to make a custom desktop wallpaper that is a little darker than the default that you see when you boot to the Windows 8.1 desktop. That's simple enough. I already made it.

But the issue is (and I've always noticed this when I use lighter colors) when I look at my monitor, the color does not appear flat and even throughout. It starts out a little darker at the upper left and then gets a little lighter as my eyes move down.

I have a Samsung LED type monitor. Model is UN19C4000PD.

So I don't know what to do here if there is anything I can do to make these lighter colors look more flat and even.

Or maybe this is something I'm doing wrong in Paint Shop Pro when I create my background. I just start with a white background layer and then add a new raster layer and then use the flood fill tool to fill the raster layer to my specific color, and finally I merge layer down and it's d

Does it look the same in and out of paintshop? if so then it is not a paintshop problem.

Perhaps that's the nature of LED monitors because they are backlit.

In PSP, revert the background image up/down and another left/right mirrorring (and save them). And place them as your background. If you see the same visual defect with the different images, the culprit is your monitor.
You may also take a sample of color in each corner with the dropper tool and compare the RVB values.

I've decided not to monkey around with my current monitor. I ordered a Viewsonic LCD. It's got great specs and a very inexpensive price.
