Bezel cut ugly, can it be fixed?

Ok, I measured my 25inch monitor and cut the bezel from MDF.
The bezel fits over the tube but I didnt account for the bowl-ness of the tube. It looks a bit ugly now. See the pictures below. Is this repairable? Would woodglue mixed with MDF dust work as a filler? Will the repair be invisible after a paint job?

I haven't much experience in woodworking. I was wondering how do you go about routing around a tube? I can only cut straight with the router... also templating the exactly measurements (or even getting exact angles and measurement of the bowl-ness) is next to impossible. Please, no suggestions on getting a plastic bezel. I cannot get them in my country and importing them costs a fortune.

You could enlarge the opening in your MDF, and then make a cardboard bezel that follows the contours of  the tube to fill the gap.

If you don't intend to remove it then use a proper wood filler to plug the gaps. You can use putty to fill the holes then cover with wood filler and when its dry sand it back to a smooth finish by hand.

Another alternative would be to cut a new bezel so the corners cover the corners of your monitor slightly, then use a dremel tool to route the corners back out to the exact size and shape you need.

From the looks of it, your plywood is roughly level with the highest point on the monitor.

If so, I would get a large piece of paper that is thin enough to see through when backlit, turn the monitor on, mark the paper where the edges of the screen are, and then cut a piece of black posterboard just outside that area.
That would let you just lay the posterboard over the plywood, and cover everything except the usable area of the monitor.
If you use smoked plexi over it, you shouldn't even see the edge of the posterboard.
