You can get a greater red shift with some monitors
Hi all. What a helpful program Flu.x is
Last December I bought an HP 27F IPSmonitor. I was delighted to find that it has a "night light" setting that produces a red shift. I combine this with Flu.x to go redder past the flu.x settings. Not all the time but when I want to. I leave this HP monitor setting on all the time and adjust Flu.x at night and daytime to my desired result
I also have the slightly older HP 27" and it has the same setting. It is less expensive but not as slim as the HP 27F. Both work very well. The older one has the power supply inside the monitor while the new version has an external A/C adapter power brick that laptops and printers have.
