The problem is one of the Back Lighting Strips in the Monitor has failed.

This can only be repaired by disassembling the monitor, and getting a new Back Lighting Strip, to replace the failed one.

If you don't have the tools or "Know-How" to do the fix.
Take it to your local TV Repair Shop.

It may be cheaper to just buy a new or used Monitor.

Agree, but I would first try and uninstall and reinstall your video driver.

Windows 10

Start|Device Manager

In Device Manager find the entry Display Adapters right click on the entry then click on Uninstall Device.
Reboot and Windows will reinstall, then go back and do the same thing but select "Update Driver" "search Automatically for updated driver software".

Windows 7

1. Open the task manager by right-clicking on the taskbar and clicking Start Task Manager
2. Under the Processes tab, click explorer.exe and click End Process. This is to clear up any graphical glitches
3. Under the File menu, click New Task
4. Type explorer.exe in the Open box and click OK
5. Click Start, then type Device Manager in the box and press Enter
6. Select the arrow next to Display Adapters and right click on the name of your video card. Uninstall
7. Reboot then go back like above and Click Update Driver Software…
8. Click Search Automatically to look online for new drivers

Well, that's not what I would call "blurry". Blurry is how things look when I don't wear my glasses. But I do agree it is a backlighting issue. But to verify that, try a different monitor before trying to fix it yourself or taking it to a shop. If you don't have another monitor, most TVs in recent years support computer input. If you get the same display problems on the 2nd display, the problem is NOT with your Dell monitor.
