Why is picking a monitor so dang hard? I can't make up my mind. I feel like I'm missing some great deal or hidden gem of a monitor or something...
Amazon and others do have aggressive sales but they are often only in a very short window. LG 34um95 was on sale for 600 dollars (I believe) for a few days not that long ago. If you managed to snap one of those up, you best belie you made a good call.
4k and gsync prices are coming down, but it's in relation to everything else. Still no G-sync with 21:9 34-inch curve for under a grand, and we won't see it until the 36-inchers and 40-inchers start popping.
And what they will do is first phase out a new line without gsync on some models and then the gsync models come later, and they are all bumped and adjusted in price in contrast.
When it comes to monitors figure out what you want in a monitor and then be dogmatic. I think that if you're on a budget you need a good monitor but not so much that you should pay a premium because its top dog. Then I'd rather get a compromise-ish monitor I'll upgrade sooner than later until something better comes along.
Monitors traditionally lasted people for many years. Since Apple shaked up the game with Retina Macbook Pro, we've gone towards a new era after being stuck in 2560x1440 for so long.
