LG 27GL83A. Why even bother with the LG 27GL850?

Wish i had learned this one existed before i ordered the LG 27GL850. It's the exact same panel, except no wide color gamut, and some pointless fluff like USB ports.

Considering how weak the HDR is on the LG 27GL850, what's the point of a DCI-P3 variant of this panel if they are going to give us a cheaper sRGB alternative?

I feel conned now. I'm paying 100 euros or more extra for something i won't probably use, since i'll most likely set the LG 27GL850 in sRGB emulation mode. The monitor market is a complete mess.

Some people prefer the oversaturated colors on a wide color gamut monitor even when displaying sRGB content. If you want a more natural appearance then yes there is absolutely no reason to get the 850 if you never plan to display any HDR content and just want a really good sRGB display. Why not return the 850 and go get an 83A?

Well, i returned two monitors already (they were defective, but still). This would make a third, and i heard Amazon is started to get a bit unforgiving to people who return stuff constantly. If the monitor isn't defective (I.E., no BLB, no dead pixels etc) i may be compelled to keep it, but i still sort of feel burned, not the least because there's a chance the LG 27GL83A might have better contrast.

The LG 27GL850 doesn't even get to 400 nits so even if you like HDR stuff it still seems pointless. Bad luck not learning about this earlier, ho well i guess. Maybe i'll like the extra saturation.

It's definitely a thing of personal preference. Kinda like when it comes to music; the purists will swear that you must have a flat frequency response in your headphones in order to listen to the tracks "the way the artists intended it to sound like" but if someone prefers to crank up the bass boost equalizer setting because that's how they prefer to listen then there's absolutely nothing wrong with that. If you end up preferring the extra saturation from wide gamut colors hey there's nothing wrong with that either, as long as you aren't doing any real professional color work I suppose.

I'm one of the guys you are talking about. I prefer pure sounds in my music and rarely touch the equalizer.

If i don't like it i'll risk yet another return i guess (here in Europe we have the right to return anything for any reason within 14 days so it's not a big deal. Worst thing Amazon can do is ban me). Funny that one has to pay at least 100 dollars extra for a feature that may actually be detrimental to the user's needs. That's what makes it a bummer because the LG 27GL850 has an sRGB emulation mode, but then i'd be paying more for nothing.

If the monitor has no BLB issues or stuff like that, i may keep it just so that i won't have to play the lottery again. If not, i'll send it back and get the other one, whenever that's available since those new LG monitors are missing in action all the time.

It is not the same ISP panel. The LG 27GL850 has LG’s Nano IPS technology. "Nano IPS Display Feel Actual Combat with True Colors Nano IPS covers 98% of the DCI-P3 color space, the professional film industry standard. The Nano IPS display delivers stunning image reproduction that brings your virtual world to life from any vantage point." HDR content is in games and videos.

Before deciding I'd check out the Nano IPS thing (independent reviews), whether it's worth having. I personally wouldn't be content with sRGB. It's an aging colour standard and limited in colour representation, while DCI-P3 and Adobe RGB (they're somewhat similar) give you better and a wider range of colours, a more vivid picture.

Interesting. I thought the result was an increase in saturation and nothing else (for sRGB content i mean). Are you saying the image will become more vibrant, and not simply more saturated?

It is for HDR content like movies and games. sRGB ISP panel is 8 bit clolor. HDR Nano IPS is 10 bit color.

"sRGB (standard Red Green Blue) is an RGB color space that HP and Microsoft created cooperatively in 1996 to use on monitors, printers, and the Internet. It was subsequently standardized by the IEC as IEC 61966-2-1:1999.[1] It is often the "default" color space for images that contain no color space information, especially if the images' pixels are stored in 8-bit integers per color channel." https://en.wikipedia.org/wiki/SRGB

"High dynamic range (HDR) is a dynamic range higher than what is considered to be standard dynamic range. The term is often used in discussing display devices, photography, 3D rendering, and sound recording including digital imaging and digital audio production. The term may apply to an analog or digitized signal, or to the means of recording, processing, and reproducing such signals"

Visual
High-dynamic-range imaging (HDRI) is the compositing and tone-mapping of images to extend the dynamic range beyond the native capability of the capturing device.[2][3]

High-dynamic-range video (HDR video) refers to a video signal with greater bit depth, luminance and color volume than standard dynamic range (SDR) video which uses a conventional gamma curve.[4]

High-dynamic-range rendering (HDRR) is the real-time rendering and display of virtual environments using a dynamic range of 65,535:1 or higher (used in computer, gaming, and entertainment technology).[5]

On January 4, 2016, the Ultra HD Alliance announced their certification requirements for a HDR display.[6][7] The HDR display must have either a peak brightness of over 1000 cd/m2 and a black level less than 0.05 cd/m2 (a contrast ratio of at least 20,000:1) or a peak brightness of over 540 cd/m2 and a black level less than 0.0005 cd/m2 (a contrast ratio of at least 1,080,000:1).[6][7] The two options allow for different types of HDR displays such as LCD and OLED.[7]

HDR transfer functions that better match the human visual system than a conventional gamma curve include the Hybrid Log-Gamma (HLG) and Perceptual Quantizer (PQ).[4][8][9] HLG and PQ require a bit depth of 10-bits per sample.[4][8]" https://en.wikipedia.org/wiki/High_dynamic_range
