I've been looking at monitors and trying to figure out just what I want. My current one is the venerable Dell U2711, which has good colour and resolution, but it getting quite long in the tooth. It's also heavy and power-hungry (about 2-4x what a modern LCD draws).


= Final selection =

I got the LG 32GK850G from jporter, it's a 1440p panel that'll run at 165 Hz. It has a handy bias light on the rear, decent colour in a standard gamut, great gaming performance, and G-Sync which is lovely for gaming.


= What'd be nice? =

 * Resolution of 2560x1440 or higher. 4K would be cool but it's probably not worth it in the smaller sizes, and larger monitors are quite pricey. My experience with work's 32-inch 4K display (LG 32UD99-W) is honestly... good but it's remarkably temperamental. Plus you need to drive all those pixels, which just makes life harder when it comes to gaming.
 * 27-inch at least, thankfully this is the sweet spot for 1440p models
 * High refresh rate, 144Hz sounds nice
 * Pretty good colour, wide gamut is nice but not necessary, and honestly probably more of a hassle than it's worth
 * G-Sync would be really nice please (though it's less important when your system can push higher framerates)
 * HDR would be nice, but this is bottom of the list


= Promising options =

I've whittled it down to a few models. Here's a comparison that may work: https://www.displayspecifications.com/en/comparison/84cb1570fa

|| Asus TUF Gaming VG27AQL1A || $760 || https://www.mwave.com.au/product/asus-tuf-gaming-vg27aql1a-27-170hz-wqhd-hdr-gsync-compatible-gaming-monitor-ac37367 ||

|| Acer Predator XB273U GS   || $850 || https://www.mwave.com.au/product/acer-predator-xb273ugs-27-144hz-qhd-05ms-gsync-compatible-gaming-monitor-ac37396 ||

The Asus is sounding good because it's substantially cheaper, has a wider gamut, might have better colour, and is more HDR-y. It's G-Sync Compat instead of real G-Sync, I ''think'', but it's kinda hard to tell because there's various sub-models of the Predators that make it less clear.


= G-Sync =

G-Sync is kinda a weird mess, but ideally you want the ones with real G-Sync hardware inside, though they're more expensive. Many other models are marked G-Sync Compatible (that's a capital-C nVidia accolade), which means they're certified to be good enough with variable refresh rate, but not ''quite'' as fancy as a real hardware board.
