Plasma's also put out a lot of EM radiation, so it can mess with radio, notable if you use RF devices, especially wireless headphones (the ones that use RF like Sennheiser's basic ones). OLED and CRT still have issues when used for desktop applications due to their burn in. All three are arguable poorly suited for sitting on a desk. Every screen technology has drawbacks. I'd argue that TN/IPS are the easiest to adapt to a desktop experience while mitigating downsides. I personally use an LCD monitor combined with a projector, but a projector requires you to build a room around it.

Just to pitch in, I got the VAST ultrawide 100hz monitor, and while it's not a dealbreaker, I personally find the ghosting quite distracting compared to my old 144hz TN panel. In fairness however, it's a new panel, by a new company, on a newish technology, and it's definitely on the cheap end of the spectrum. From the posts on Massdrop, it seems either it's less noticeable to some, or perhaps some of the panels are better than others in that batch, so if you're going with a trusted brand, it'll might be less noticeable. That's my 2 cents. 
 
TL;DR: You'll probably like it, but don't be afraid to return it if you don't.

well i wouldn't say this is something for holy shit but more like for shit manufacturers say.
 
they have tested these fancy HDMI cables and were really surprised, maybe there is a similar story with different projector screens.

According to LG, that monitor does have HDMI 2.0

If you are setting the resolution from the NVIDIA control panel, make sure you have checked the "PC" section of the list.
