I used to be nuts about spectrum for awhile. I used to believe that my issue was with spectrum and flicker. I don't fully understand how they get these spectrum charts because take any TN LED from 2013 and compare it to some low end TN panels now and the color reproduction now is incredible and even the viewing angles are starting to close in on IPS. Some monitor maker just made a claim that there TN has the same viewing angles as IPS don't think it's out yet. Here check out this spectrum from a plasma. I own 6 plasma TV's in my house.
Lots of red middle green little blue.
I believe the panel powering the monitor plays a bigger role. A lot of the newer 2019 monitors are using a new panel from AU Optronics. The quality of these compared to anything even last year is next level. They have IPS panels with a GTG of 1 now. Panel type also is a factor VA/TN/IPS. Check out this video from Linus especially on the first monitor. Its a VA panel look how smeary it is when playing games. The pixels can't change fast enough so you don't get proper color.
You get greenish/washed out ugly colors when the monitor isn't good enough. Even check the LG at the end it's great for gaming but not good for internet reading in terms of image quality.
I believe it's this video where he talks about the panel behind the screen when Linus reviews the first 300hz Laptop.
Does anyone else know how these spectrum charts work?? Do they account for brighness?? I know that if you control the gamma and turn the brightness down to zero you eliminate a significant amount of blue light. I believe it was Eizo who makes these claims on their site by just dropping down to 5000K you eliminate a certain percentage of blue light.
Anyways interesting none the less.
It's interesting as well because it's hard to get this information but monitor/TV makers keep changing their LED quality but don't really make it too public. LG did in 2017 models of OLED TV's.
