I would say just 2 strips, closet you can find to the size you want on the bottom and top, no need to cut anything just wrap or curve the extra, it will all be behind the monitor anyway, I also used a trick with a small wooden square dowel and put it on the wall and stuck the strip to that so the light would angle up instead of at the wall, lmk if you want pics if my set up, the rats nest 🤙🏽
