How many nits do I need for HDR10?

[singhcr]

I am starting to look to get into the UHD game at last. I already have a Dolby Vision compatible receiver, but I need a new TV and UHD player.

I had a CRT 1080i rear projection TV for years and loved it, and I was forced to upgrade when it finally bit the dust a few years ago. My current Panasonic VT60 plasma improved on that with superior detail, color, and even better blacks. I was hoping that OLED would be my next step when getting into 4K, but I am hearing again and again that without a bright enough TV my UHD movies just won't look correct (too dark, etc).

Black levels are extremely important to me and having washed out blacks annoys me more than anything else as color in general suffers with such a display. I know there are high end LCD TVs like the ZD9 that people here like, but even that won't have the same blacks as an OLED. It's just a limitation of the panel technology, just as OLED will probably never have the same light output as an LCD. Assuming it was bright enough to tone map correctly, I'd rather sacrifice a bit of brightness for better blacks than the other way around. I watch my movies in a totally dark room anyway.

Is there an approximate target for what's needed to make HDR10 work? Would a 800-1000 nit TV be enough as some titles are mastered at a 1000 nit level, or do I need to go higher to make the 4000 nit titles look any good? From what I have read LG is coming out with a new OLED panel in 2018 so hopefully that will be helpful for me as they are supposed to be brighter.

It seems that I have to trade off between brightness and black levels when stepping into the world of HDR which is frustrating for me because in the past I never had to do that. Any suggestions would be appreciated!
