$200 Asus PB238Q
After about 8 years my old 17" 1280x1024 lcd ccfl monitor is turning yellow so it was time to replace it.
What to get? What do I use it for?
For games and movies I would want a wide screen. For websites and office I would want a tall screen. I want both portrait and landscape. But you can't just rotate any LCD on it's side and expect a great view. That's where IPS comes in. IPS is all about viewing angles.
What size? Why?
1080p @ 24" since a 24" has a higher pixel density than a 27" monitor at the same resolution. Large selection of consumer IPS. And price.
Why not 2560x1440?
My video card can not play games at that resolution. Mainly cost.
What about pulse-width modulation?
At any brightness less than 100% you activate the PWM. Some people can get sick from the strobe effect. I turn down the brightness in the OS settings, not the monitor and I don't get the pwm strobe.
When you consider you next monitor, go to a store that has an IPS monitor with pivot and take it for a test drive. You may like it.
