To make long story short, l had been using non-calibrated, non IPS, lower resolution(1920x1080 27") monitor as PP monitor.
"Lower" resolution"?! Don't tell that to my 1366x768 and 1280x1024 work monitors :-oI'm glad to report that after spending nearly $3000 on new PC + higher resolution & pre-calibrated monitor + Canon Pro-100 printer(bought it new on CL for $100), I have completed the job before the due date.
When spending €50 on a calibration device, you don't need the very best monitor, they just provide more gammut and better viewing angles. But +1000 for calibrating your monitor (paying someone or diy), it's the most important thing next to buying a lens for your camera.
I never thought I would jump into higher resolution monitor world, until I see it in action
There is no point for me to buy and use 2560x1440 monitor when my 3yrs old laptop can only support up to 1920x1080. So, it was a complete system upgrade for me. The new BEAST is so fast. I'm blazing through those RAW files in LR. Loving it.
