novideo_srgb VS MHC2

The only way to fix this issue is to use an open-source utility called novideo_srgb. https://github.com/ledoge/novideo_srgb

There's novideo_srgb but it only works for Nvidia cards.

I haven't watched the video but just in case it isn't mentioned there I want to mention it here: You need to consider Windows' inability to properly color manage, you will see oversaturated colors in most applications unless you use a tool like: https://github.com/ledoge/novideo_srgb

Also, since you're concerned about color accuracy, check out this program: https://github.com/ledoge/novideo_srgb

And while you're at it, be sure to clamp your monitor to sRGB with this tool for NVIDIA cards, unless your monitor can properly display HDR.

- Odd default color settings; saturation is too high, and the default gamma curve is too high causing everything to be washed out (with no setting to adjust gamma specifically; I can't seem to find good settings myself). If you have an NVIDIA GPU, you can use novideo_srgb in conjunction with RTING's ICC profile and monitor settings to get (what I perceive to be) near perfect colors.

Unfortunately yes. The display comes "color calibrated", there's even a nice report included as seen here, however it's with a widen colour gamut of 125% sRGB. There's an sRGB mode, but it locks the brightness to 75, which is too much imo. Currently I'm using this program to clampen it, which I'd say works quite well, but I can't verify if it's 100% sRGB with this and I don't have an ICC profile to ensure so. The AMD catalyst driver has something similair to this integrated for folks that have an AMD GPU.

For wide-gamut monitors that have oversaturation, I highly recommend novideo_srgb for Nvidia, or using AMD's own SRGB clamp to clamp colors down to SRGB to fix oversaturation. It'll fix oversaturation for the entire screen, not just a specific application. You can also use your own color profile for more accurate colors with novideo_srgb.

get the srgb clamp tool , go to advanced-dithering : enable, spatialDynamic2x2, 8bit (or 10 if your monitor is 10bit native). dont need to do anything else, dont need to activate the clamp.

Here's the thread where I found the settings that gave me the best results for novideo_srgb: https://github.com/ledoge/novideo_srgb/issues/18 I'd follow aufkrawall's findings, as those worked really well for me.

This reverse engineered documentation was the only real resource for a while, but since then Microsoft have published their own documentation here. The new ICC profile stuff is specifically the MHC2 tag.

There's not really much benefit to the HDR Calibration tool over just using CRU to set the max brightness. With better calibration tools MHC2 advanced color ICC profile extensions allows full GPU-based calibration using MHC2Gen as an alternative to tools like novideo_srgb but that's a bit pointless on LG with 3dlut support. Could be useful on monitors with wonky calibration and gamma though.
