I'm trying to decide between two 27" monitors - one is a 4K (3840 x 2160) monitor that covers only sRGB and the other is a QHD (2,560 x 1,440) monitor that covers Adobe RGB. Both monitors are of high quality, with an IPS panel and 10-bit engine. For the sake of the discussion, let's assume that they only differ in their resolution and color space coverage.
I plan to use the monitor for RAW development and photo editing, with the goal of exporting for the web - social media, email, mobile apps, etc. I print very rarely and when I do it's at a consumer-level camera shops.
Based on what I've read, this type of use means that the advantage of a wider gamut monitor will come into play only when I'm developing/editing the photos. Because once they are exported, they are compressed to sRGB. If I had printed more seriously I could have exported with a wide-gamut printer in mind, but I'm not. Photography is a hobby for me.
Currently I'm using a low res sRGB monitor, so it's a little hard for me to value the gain in higher resolution compared to wider gamut. I assume that I would appreciate both, but not sure which one would be more useful.
I'd be glad to hear what other people think - whether for a use case like mine the benefits of higher resolution take over wider gamut or vice versa.
