I confirmed that the Atomiswave does work with this monitor model Benq rl2455hm in 31khz mode!!!
As long a system can output 31khz RGB HV (a.k.a. VGA format) the BenQ RL2455HM can work with it.
I own the exact same monitor.
Not all VGA monitors or TV’s work. I was surprised that my LG 55 TV worked. I was super curious…lol.
HDTVs are the exception not the rule. Many HDTVs are strict with the NTSC specs. If the signal is off spec the TV will report the signal is incompatible or "out of range"
Sony’s HDTVs are notorious for this.
PC Monitors are more forgiving
