A few of them:
There are a few 4k monitors in the mix however, that is just for consideration. Am mainly looking for a 1440p 27" IPS panel which, if its 60Hz too is fine. If its 144Hz, its better too!
The only reason to include TN panels here is for the 144Hz and, also better in terms of no BLB, etc..
You'll want to stay away from LCD monitors to avoid back light bleed. On top of that, ASUS monitors seem to have a lot of dead pixels, from what I've read.
I'd trust some of the consumer reviews. When hunting for a PSU I thought I found a good one with EVGA's 850 GS but was discouraged by numerous negative reviews on Amazon and Newegg. Went to the EVGA forums and found similar scrutiny. So I chose EVGA's 850 P2 instead, paying a $10 penalty for a product that works brilliantly.
Some reviews from my retailer;
In all honesty, if you see too many poor reviews of a product you should avoid it. Check Newegg and Amazon. There you will find an abundance of reviews on ASUS products.
