LCD technology still has a few drawbacks in comparison to some other display technologies:

• While CRTs are capable of displaying multiple video resolutions without introducing artifacts, LCD displays produce crisp images only in their "native resolution" and fractions of that native resolution. Attempting to run LCD display panels at non-native resolutions usually results in the panel scaling the image, which introduces blurriness or "blockiness".

• LCD displays generally have a lower contrast ratio than that on a plasma display or CRT. This is due to their "light valve" nature: some light always leaks out and turns black into gray.

• Older LCDs had longer response time than their plasma and CRT counterparts, creating ghosting when images rapidly change; this drawback, however, is continually improving as the technology progresses and is almost imperceptible in current LCD Computer Displays and TVs. Most newer LCDs have response times at approximately 8ms, with the exact response time varying according to the type of panel and manufacturer.

• LCD display panels have a limited viewing angle, thus reducing the number of people who can conveniently view the same image. As the viewer moves closer to the limit of the viewing angle, the colors and contrast appear to deteriorate. However, this negative has actually been capitalized upon in two ways. Some vendors offer screens with intentionally reduced viewing angl, to provide additional privacy, such as when someone is using a laptop in a public place. Such a set can also show two different images to one viewer, providing a three-dimensional effect.

• Some users of older (around pre-2000) LCD monitors complain of migraines and eyestrain problems due to flicker from fluorescent backlights.

• LCD screens occasionally suffer from image persistence, which is similar to screen burn on CRT displays. This is becoming less of a problem as technology advances, with newer LCD panels using various methods to reduce the problem. Sometimes the panel can be restored to normal by displaying an all-white pattern for extended periods of time.

• Some light guns do not work with this type of display since they do not have flexible lighting dynamics that CRTs have. However, the field emission display will be a potential replacement for LCD flat-panel displays since they emulate CRTs in some technological ways.

• Some panels are incapable of displaying low resolution screen modes (such as 320x200). However, this is due to the circuitry that drives the LCD rather than the LCD itself.

• LCD monitors may tend to be more fragile than their CRT counterparts.
