First off, I value discussion for the varied opinions because my monitor at my desk is an 10+ year old 60Hz IPS 1680x1050 that I'd like to replace with a 1440p high refresh display with good color and HDR if possible (that doesn't cost $750) so I'm very interested in everyone's input. I leave most of my statements open ended so the reader can ultimately decide, but there are sometimes things that stand out, like the fact that many displays don't meet proper HDR standards under scrutiny by independent reviewers despite the advertising as HDR capable. Both Tim from Hardware Unboxed and the folks at Rtings came to the same conclusion that the 27GL850-B falls short on HDR. Absolutely I agree with you that it doesn't mean people aren't going to like it, but there comes a point where the shortfall can start to be significant. And even if the user likes what they see, there is still a defined standard for HDR that technically should be met. The display has to be capable of peak brightness above 1000 cd/m2 (m-squared, superscript not working). You'll see that many TVs fall short here if you look at the test results on this page:

Now here's the peak brightness of the LG 27GL850-B:

It's even less than many of those TVs, which mostly also don't meet HDR standards. That's all I'm saying. It doesn't meet the technical definition. But, certainly you would want to make sure the TV or display is not at the bottom of the list or you might be disappointed. There are actually several levels of HDR defined, but as Tim stated the LG display doesn't even meet the lowest tier definition, which is HDR-400. See here for more info:

Yes, I saw the reviews for the new Gigabyte monitor. I liked it until the reviewers scrutinized it
Really, I do agree with you. At some point you have to pick something and just see how it is. Obviously price is a big starting point for many people, and then you just try to find something in that range that the manufacturer has done a good job with - the best model at the price you can afford. It's not always an easy choice. I think I'd miss the beautiful color of my TV if I get a monitor that isn't OLED, but there aren't many OLED monitors out there right now and I'll have to choose between TN, IPS, VA, or whatever - and they all have their strengths and weaknesses. There are some games I can't play on the TV, and my old monitor just doesn't pair with my new PC. I'm glad we are getting more HDR options in the monitor market, but I haven't decided yet. Honestly, I'll probably put off buying a new monitor for a while by only playing the games suited to TV just so I won't have to spend the money. Time will only bring better and hopefully more affordable options the longer I wait, but if the product and the price is right I will go for it. I did want to provide some more info here because I do have some applicable info from my own efforts and I think more information is always better. So I guess you could say I've got some analysis paralysis! Seriously, though, I think you said this before - very few options, if any, are going to have everything you want.
