Recently finished my setup in my bedroom its a small-ish room so ive mounted the monitors onto the wall. Ive been PC gaming on and off for 12 years now and for the last 2-3 years ive found gaming on my bed is great, with only the sofa as the next most comfortable setup which i'll do after ive saved enough money for a deposit on a mortgage.
Build:
2cm thick ply wood sheet screwed onto the wall (plaster board onto a 3x2" timber frame) across the wall length, painted same colour as the wall (red/blue walls as of 8 years ago - i used to be very patriotic for my countries union flag. It'll do until ive saved enough money for a deposit on a mortgage.
1x flat wall bracket, 2x swivel wall brackets.
1x cable trunking, white to match the wall shelves, otherwise wouldve gone for black to match the monitors.
3x 27" ASUS VE278Q moitors, 60Hz, 2ms.
3x 5meter DVI cables
Im an electrician so:
a 4-way exension socket behind and feeding the 3x monitors. Fed from a 4-way surge protection socket under my bed feeding PC, speaker system, keyboard. Fed from a switch on my bedside table. Fed from the wall socket by the far-end monitor - where my desk used to be.
a blue LED strip light behind the monitors is connected to my bedrooms night-light circuit connected to other strip lights around the room for a low-lighting effect during dark hours. Switchable from the rooms 3-way wall switch by the door.
