Apparent brightness diminishes with distance from the source, with respect to point source illumination, illumination diminishes by half, when distance is increases by a.factor of 1.4, (the approximate square root of 2). And if anybody wants to watch a movie in a fully lit room, I wouldn't be able to help then with set adjustment. As for loss of contrast with higher brightness levels, you have to increase set contrast, along with color saturation, then use the brightness control, to compensate for apparent brightness loss. In other words, bright crimson, blocks more of the back light, than pale pink. A color's density affects either transmitted or reflected light values, (expressed as a percentage). Now I'm not such a dolt as to increase brightness to the point where I can't get black on screen. .Accordingly, if the available gamma, shrinks, I'll gladly suffer the loss of shadow detail, as opposed to looking at the washed out screen you're describing. As far as maximum nits available with any screen, I'll gladly turn a too bright screen down, as opposed to pegging a brand new monitor on all elevens, then watch it go to sh!t from there. So, if a monitor isn't going to come out of the box at 300 to 350 nits, Newegg can keep it. Which is also true of my cheap a** Walmart, (Vizio). The trouble with energy saving features" is, the picture looks dull, flat, and washed out.Just saying, "Energy Saving", is something to write on the box, but nothing anybody in their right mind would want to watch. Why would anybody need a "video player" to watch broadcast TV on an ATSC tuner equipped TV?? the tuner merely repeats the color space it receives without tweaking it. If a tuner did modify the color space of different content, networks would be getting their pants sued off, for modifying the "mood", and "substance" of the content. A beer ad is sparkly. A lobster is saturated red. A child coming home from scholl with a bad report card, from not having attended whatever preschool, is shades of gray. Now, take a few moments to watch this piece of sh!t propaganda ad for "Rexulti". Notice first the woman at the beginning looks like a basset hound, (albeit a muted blue & gray basset hound), and further note as, "the drug kicks in", the color balance is shifted from muted grays and blues, to sunshine yellow: They even drop the lighting contrast to alleviate the simian lines on her face, thus making her look "happy". Now, every broadcast technician has his or her own opinion, of how every thing should look, on THEIR screen,which isn't necessarily calibrated with YOURS. You go through half dozen commercials, you get a half dozen interpretations of color balance, saturation, brightness, and contrast. Whether or not they're mixing for the same color space, matters not, the end results vary wildly.
