Not sure why you felt the need to post coverage of this twice. Again, I'm not too exhilarated when the LG B/C/E series & Sony AF series OLED TVs exist (up to 77"). The "variable refresh rate" up to 120Hz thanks to the DisplayPort is the only advantage on the spec sheet, but of course the LG TVs I just named can also do 120Hz if you downscale native rendering to 1080p, and variable refresh seems highly counterintuitive without G-sync/Freesync supported. There is nothing about an advantage to input lag, color gamut, or HDR brightness ranges over the TVs we already have.
I think the new 43" Asus ROG Strix XG438Q monitor-- a VA Panel-- is a bit more relevant in the space between those monster 4K OLED TVs and the best 27"-34" 1440p IPS/TN monitors:

The 600 Nits brightness and 4ms response times aren't as good as the LG/Sony OLED TVs, but you get Freesync 2 (supported over HDMI), you will almost certainly enjoy a better input lag due to the panel type, you won't have to worry about ambient light washout, and you won't have to worry about burn-in.
But mostly it will be that unseen spec: price. Expect this monitor to cost around $1K or less, not the $5K HP quoted for its 65" Omen Experium BFGD which actually has G-Sync HDR, and that Dell is too afraid to even list for their new OLED "gaming TV". This 43" monitor is a stop gap. That is a product with a home outside a tech show floor. If you're willing to spend $5K+ would you really pick a 55" 120Hz OLED over a 77" 60Hz OLED or an 82" 60Hz VA? This is 4K.
