The K242HYL has a better display type than most medium monitors that were released in the last 12 months. This Acer LCD screen has an LCD display type, whereas most new medium monitors have an LED display type.
An LCD display type is actually the worst display type amongst all medium monitors that have been available for around the same time as the K242HYL.
An LED display type is the best display type across similar types of flatpanel monitor.
It may also be worth considering one of the alternative flatpanel monitors that have an LCD Display currently available including because of it's better review score, the LG 23MP68VQ (£116.25).
If the display type of this medium monitor is too bad for you then you might want to consider the Acer KA240H (£94.98) (LED), or the HP V243 (£99.99) (LED) which is also cheaper.
