Putting a paver brick edging around my front beds and one bed in the back is a major project for me this summer so IÂm dealing with some of the same questions that you are. IÂve always liked the look of brick edging but have avoided doing it previously because of fear of grass growing though the gaps  plus itÂs easier to change the shape of a bed if when the beds are just trench edged. My front beds are (I hope!) finally pretty much in a shape I figure I can live with for a while. That plus physical signs that it is time to think about reducing garden chores has made this the summer of the edge. To eliminate the grass worry, IÂm using the Curve-rite aluminum edging (the more flexible one  there was two different types at the supplier) between the grass and the bricks. The bricks are set on a couple of inches of screenings, compacted with a rubber mallet. IÂm also using the screenings to fill the gaps between the bricks  although I suspect I need to be using concrete sand or something like that. I will probably have to add sand as the screenings settle. The edging and the bricks are set ½" or so above the grass roots. Hopefully that is high enough to be a barrier to the grass but low enough so the lawnmower can easily run over it without the blade hitting it. My bricks werenÂt free unfortunately :-) But itÂs the aluminum strips that are the pricy part. Here they are $20 CDN for an 8 strip with 5 support spikes. The paver bricks for an equivalent 8 are only a few dollars. So far it looks good and I like the look better than the trench edge. It is certainly easier for the lawnmower  and you donÂt have to be as careful walking because thereÂs no risk of falling into the trench! IÂm going to backfill behind the bricks with pine bark mulch in one area but just slope the soil in the bed to the back of the bricks in most areas. I plant very densely with a Âno bare ground philosophy so I donÂt have a problem with erosion . I generally donÂt mulch my garden beds. The plants are my mulch! Some of my filler plants (particularly feverfew) get cut down during the summer and are left on the ground to compost in place. In most places, the plants will overhang the brick edging to soften it and deflect some of the force of heavier rains. Since I leave the previous year's growth standing until new growth starts in spring, that should, I think, help reduce erosion issues in the bare seasons. We'll see next year I guess!

Stones would look great at first but would gradually be home to weeds and then you'd have to move the stones to get the weeds out. Nope not my cup of tea. Edge with your pressure treated wood. Lay down a thick layer of newspapers over the weeds and grass that is there tucking it under the wood and put wood bark or chip mulch on top of the paper The paper and mulch will kill off anything under it. You will have to do this every couple of years because the paper and mulch will rot down but it's better than digging weeds out of rock

Your problem may be the video card, the monitor, the setup functions built into the monitor, or setup parameters in the software drivers for the monitor and card. to check out the monitor, connect it to another computer, even a laptop will do. Before you connect the monitor, set the display mode of the test computer to a generic VGA (640 x 480 pixels). Almost all monitors will recognize this mode and it is supported by generic drivers. This circumvents the need to install a driver for your monitor. If the monitor works ok on VGA, there is a good chance that it is ok for other modes.

Numerous driver incompatibilities and goofy settings (as described in the link by zep516) are among the common problems many Windows 10 updaters have experienced. One of my PCs had a manufacturer's message popup saying in so many words - "Don't upgrade this PC to W10, the drivers won't work and your PC will become inoperable" As described in another thread, problems like this are why the big (and well- informed) private and public employers intentionally DON'T update their IT software when there's no benefit to do so and a risk of problems. It's senseless. Can you roll back your PC to the earlier Windows version? That would be my recommendation.
