When may distort geometry occur on an LCD monitor?

A distorted monitor display can cause images to appear blurry or unfocused. It’s usually temporary and resolves itself over time, though sometimes it’s a sign that your monitor is defective or needs to be replaced.

Typically, distorted geometry occurs on monitors that aren’t in use. However, it can also occur when you’re using your monitor for gaming or other applications that require a fast refresh rate. 

When it occurs, the resolution may be incorrect or the connections to your computer or video card aren’t working properly. You can test whether the resolution is correct by connecting your monitor to another computer and seeing if it displays well. 

It’s also possible that the problem is a faulty screen or bad pixel, which are called dead pixels on LCD monitors. These problems are rare, but they can occur in older models, so it’s important to verify the issue isn’t related to a hardware or software problem. 

The pixel layout on a monitor is designed to produce an accurate representation of the scene in front of it. The number of pixels in each cell, the size of each pixel, and how they are placed within the cell all play a role in producing a clear picture. 

Unlike CRT screens, LCDs are less fragile and require less electricity to operate. This saves money, especially if the screen is used in conjunction with an energy-efficient computer. 

They are also brighter than CRTs, which can be useful for displaying images with strong contrast or dark backgrounds. Typically, LCDs are available in ranges of brightness from 250 to 300 nits, which is enough for most users. If you’re a serious gamer, you might want to consider a higher nits range to improve your visuals. 

Distortion issues are generally minimized on curved-screen monitors because they take advantage of their curve and aim light at the viewer, rather than blasting it off in a straight line. This makes it easier for the eyes to take in an image, which helps alleviate eye strain. 

Some diagonal patterns in CAD programs can interact with the inversion process, causing objectionable flicker on some monitors. This is only an issue if the manufacturer has left the common-electrode voltage grossly mis-set, but it’s still something to be aware of if you’re considering purchasing a new display. 

It can also be caused by a loose or defective video cable. Disconnect the video cable (usually a DVI, VGA or HDMI connection) going from the back of your computer to the monitor and check that no pins are bent, burnt or broken. Once verified, re-connect the cable to your computer. 

If the problem is not resolved by re-connecting the video cable, your monitor may be defective. The distorted monitor display will likely return to normal once your computer is restarted. If you’re still experiencing a problem, contact your dealer or customer service team to determine the next steps for repairing or replacing your monitor.
