I needed a new monitor and spent weeks researching in my spare time, paralysis analysis. So many reviews out there with many people advising to wait for new displays coming next year. However I needed something now, that was good enough but not too expensive to tide me over for the next year or two until spending $1000+ on a monitor is actually worthwhile. Seems alot of the current ones on the market suffer issues and are compromised in one way or another.
This one had consistently good reviews and is recommended at pcmonitors.info. They actually recommend the LG27UD68 which is even cheaper $574.20 with the coupon, but this is the newer version which is supposed to be very similar but a little better.
I ordered it yesterday around lunch and I received it today. Loving the 4K resolution everything looks very clear and crisp running off a Surface Pro 2017 at the moment.
Tempting, but I can't bring myself to spend this money on a monitor until they offer real HDR10. You are right that every monitor seems to be compromised in one way or another, not sure why they are so slow to catch up with the latest technologies and what people want.
