If you have a triple screen set up on your Sim Racing rig and want to lose the black strip that occurs where your screens meet then this is the basis of a DIY Bezel-Free Kit.
The original ASUS ROG Bezel-Free Kit was an accessory that enables gamers with multiple-monitor setups to visually eliminate the gaps where their displays connect.
In addition to the four mounts (2 x top, 2 x bottom) you will need 4 M6 bolts (10mm / 20mm) and some Fresnel Layer or similar.
Fresnel Layers can be found covering the LCD panel of an old monitor. So you want to be finding an old display and carefully dismantling it.
These mounts are designed around Iiyama monitors. The slot gap is 24mm and depth is 18mm. The bottom is snug and the top has more space.
