I've ordered this monitor online, but upon arrival it has an uneven backlight or backlight bleed. Namely, moving an image from top to bottom of the monitor increases its brightness by about 15-20%, and the "blue" Windows desktop looks ... gradient.
I was wondering if I could bring my online-bought monitor into the store and would be able to exchange it for one with a more even backlight.

Re: Uneven backlight in just purchased Best Buy LCD.
My guess on this is either one back light ccfl is cracked/unplugged or the power supply is not running one side of the ccfl back lights, either way you should absolutely take it in for replacement asap

all red, sounds like a bad cable connection or bent pins in the cable connector ends, visually inspect them. If the red you speak of is very faint and uneven it could also be the backlight in the monitor failing, but likely a loose cable
Modern monitors and desktop computer use universal power cables, so you should be able to go to an office supply store like Staples or Office Depot or an electronics store like Best Buy and ask them for a monitor power cable. It will have a three-prong end to plug into the wall and a six-sided end with three recessed slots to plug into the monitor.
If you want to buy online, monoprice.com has grest prices on cables.
You should be able to repair the backlight power supply. That model monitor uses 2 different versions of the power supply. If you can open the unit and take a few pictures of the power supply and send them to us at: firstname.lastname@example.org also include any model numbers from the power supply. We will cross reference the board and get right back with you about what you need to do for the repair.You can also check out our web site at: www.ccl-la.com. If you need parts we carry them in stock.
I hope this helps, if so please rate our solution.
Look for one on eBay with a crushed screen. Shop carefully and buy the cheapest vs. newest one you can find. A store return being your best bet.
Just think of all the folks who drop them hooking them up or otherwise "pull a whoops" within a few days of upgrading from there old "built like a TANK" CRT and 90% or so end up in the "semi trailer of store-returns" market, and most of those end up on eBay.
AND you'll usually pay a fraction for a like-new (except the LCD) whole monitor than the factory single board price (If even available) and have extra good parts that can be sold or saved for future Fixyas!
It sounds like your backlight isn't working properly. LCD screens have backlights that illuminate the colors produced upon their surfaces, so that you can easily see the screen without an external light source. In your case, it sounds like your backlights either aren't cailbrated, are damaged, or were produced unevenly.
There is most likely not a fix for this, though most all LCD screens have some form of light distortion. My own LCD screen is slightly brighter around the edges, where the backlights are located, but this is only noticeable when displaying a completely black screen.
First off it could be the backlight bulb or the LCD inverter. I would try the LCD inverter first it will cost about $25 and is easy to get to Take the face plate off around the monitor and the LCD inverter is at the bottom. It looks like a strip of circut board with plastic coating over it. Most of the time it is the LCD inverter.
But if its the Backlight bulb you might be able to take it to a local tv repair shop. you can order the backlight bulbs online but they are gragile and tricky to replace. you have to seperate the layers of glass on the screen abd the backlight will be at the top inbetween the layers of glass. If you do decide to do make sure to wear rubber gloves because the oiles from your fingers will get inbetween the glass layers and cause foggy spots when you put it back together.
Normally when an LCD monitor goes black, it is because the inverter goes out (which essentially is the backlighting). To verify this problem, hold a flashlight up to the monitor while it is turned on and see if you can "see" the picture. If this is the case, it could be repaired, but realistically, the cost to replace it might be cheaper (and you would probably end up with a larger monitor to boot).
