Hi there,
LED is LCD btw - the LED part is just the backlight. Standard monitors just advertised as "LCD" will use a CCFL baclkight. The edge-lit LED backlights offer benefits with lower energy use and allow for thinner screens - but for image quality they are generally no better than CCFL.
As for a gaming 1920x1080 22in, do you have a budget it mind?
This BenQ 24in monitor is generally well regarded for gaming, but if you want super fluid gaming then a
120Hz monitor is the top dog, however they do command a price premium.
