My flat panel monitor has begun having problems displaying pictures. The pictures, my own files, and those in ads looked ragged and appear to have small "blocks" of color that are visible rather than being in-focus and sharply defined.
I've used the monitor controls to reset the monitor to its original factory settings. That didn't help. I've looked to see if there are any other drivers available, but I've only had the unit about 4 months and I've not found any.
Any suggestions as to why the monitor is suddenly not displaying pictures correctly?

The .inf drivers for almost any computer monitor is already built into ALL operating systems.
There are, generally, no drivers necessary or available for monitors.
This is the way it works. A computer's Graphics Card (which is, effectively dedicated a mini Motherboard with its own dedicated RAM Memory, Heatsink and/or Cooling Fan and Microprocessor - GPU), purely to power and manage the overall graphics capability of the computer. The Graphics Card does most of the work involved in taking encoded or decoded image files from your computer, from a DVD or VCD, from the internet or from a typical, external imaging source like a Smart Phone, Webcam, Digital Camera, Camcorder or a Media Player and then and interprets these image files into the analogue or digital signal (depending on monitor type) it sends to the monitor for it to resolve into an image.
A monitor has a range of Resolutions it can operate within, and if the Graphics Card or Graphics Chip Setting are set too high or too low, outside this range, the next time the computer is restarted or shut down and powered up again, the monitor might be incapable of resolving the image and therefore remain blank, as the computer boots, leaving the user blind to its Desktop.
Other faults preventing monitors from displaying images include foreign metal objects or bent, touching, pins shorting in the connectors at each end of the VGA (Analogue) and DVI (Digital) Video cables that link the Monitor to the computer. The cable may also have a failure or a fault somewhere along its length or a failed connection at the junction of cable and connector.
The quality of the image displayed on the Monitor is mainly governed by the resolution of the image, which is controlled by the software governed settings of the Graphics Card
If none of the above is preventing the Monitor from functioning then the Monitor might have an internal fault. The inside of Monitors and TVs are a hostile, non User Repair Friendly working environment, with lots of capacitors storing relatively high charges even when the monitor in not connected to the mains electricity, that can seriously injure or even kill an inexperienced repairer.
Internal monitor repairs are rarely economical because a successful repair often requires the replacement of a faulty internal component, the cost of which, when added to the labour cost involved in the repair, is unsustainable, given the widespread availability (due to the rapid uptake of HD technology) and relatively low cost of Warrantied new and 2nd user models in the marketplace.
If your Monitor is powered by an AC/DC Power Adapter, check for any faults with the Adapter that might be preventing the power from reaching the Monitor and if, found, consider a replacement adapter from here or from similar sources to this:
If the monitor proves to be faulty and none of the above solutions remedies the fault, it may be time to consider buying a new Monitor.
Definitely do not waste any more time looking for Monitor Drivers.
I hope this helps.

A ghost on your screen is usually caused by a second or reflection of the same image getting into your monitor, and the space between the real image ant the ghost is the delay in time or extra distance the second image travels before it is displayed on your screen. It is usually caused by a defective video cable or a cable longer than usual like 8 feet or more. Also is your monitor plugged into the same outlet as the computer, and is the case on your computer as all are possible reasons for your problem. Some times adding a ground wire from monitor to computer can correct problem. This can be a problem that takes some real detective work to find, and all I can do is suggest some possible causes.
It may have one of reasons: 1. "Dirty" supplying voltage in the monitor - check all electrolytic capacitor. 2. Bad controller chip - check if it gets extremely hot when working, also you may see darkened area on other side of the PCB where that chip is located. 3. Loosed connection between controller PCB and the display itself - disconnect the cable and clean contacts, especially of blade connector on display side, check if there are some overpressed contacts.
