Can You Use a Laser Pointer On a LED/LCD TV Screen?
FAQs - Updated for 2020
Why does laser not show on TV?
Certain types of TV screens, especially LCD and LED monitors, are designed to keep glares and certain pigments away from the screen. Your TV monitor contains a polarizing filter, whereby the area between colored pixels is painted black. Therefore, TV monitors absorb incoming light, giving you a better contrast of colors. Many traditional laser pointers that show up on projector screens or matte surfaces will not be seen on TV monitors.
In addition, lasers that do show up on TV screens may cause pixels to act up. This is where the class, or level, of laser is too high and damages your screen. Since there is no fix to this, we do not recommend using a regular laser pointer on TV screens.
Can a laser pointer mess up a TV?
The short answer is “yes”. Laser pointers may damage pixels on a TV screen if their class (or level) is too high. Generally, lasers that run on 5 mW of power or more are not safe for TV screens. The damage is usually permanent, so we do not recommend using traditional laser pointers.
Instead, consider getting a compatible presentation pointer that will also make you look professional!
[Solutions] Are there laser pointers that work on an LCD/TV screen?
Instead of using traditional or regular laser pointers, there are digital pointers that are designed to work with LCD and LED TV screens.
We have reviewed a number of these pointers and found the Logitech Spotlight Presentation Remote to be the best option. This digital pointer is compatible with Mac and Windows, has a long range of 98 feet (30m), and comes with a highlighting function and timed alerts. The device also allows you to choose between USB and Bluetooth transmission. However, its price is on the steep side.
A more affordable option, the Doosl Presentation Remote , offers great value. It comes with Mac and Windows compatibility, an anti-lost reminder and is rechargeable. While it has a beautiful lacquered appearance, there are no additional timed alerts.

What is a digital laser pointer?
A digital laser pointer is designed to work with LCD and LED TV monitors. This is in contrast to regular lasers, which may not appear on TV screens, or may cause damage to pixels. Here are some digital laser pointers that we recommend using.
Does the Logitech R800 presenter really work on a TV screen?
The Logitech R800 is a green laser pointer that operates at a range of up to 100 feet (30 meters). It is compatible with projection screens, plasma and LCD, so as long as your monitor is one of these types, there should be no issue getting it to work. However, it requires you to plug in a USB wireless receiver, and is only compatible with Windows Vista, Windows 7, Windows 8 and Windows 10 operating systems. If the R800 is not suitable for you, check out our comparisons of similar models here.
Some users have commented that the R800’s green pointer is not very visible on their TV screen. If you are concerned about it, you might want to purchase a presentation pointer with spotlight or highlighting feature, such as the Logitech Spotlight Presentation Remote .
If you do happen to find a laser pointer that does work on a TV, then you may notice that some of the pixels on your TV may start to act up. The issue with this is that the level of the laser, or what is known as the class, is too high to be compatible with your TV’s screen. As a result, it gets damaged.
Should I Present On a TV?
TVs are an excellent alternative to your classic professional projectors because they’re a fraction of the cost and often come in large sizes. They can also be connected directly to your laptop and only require an HDMI connection. They also provide a large, crisp, clear picture of your slides or presentation.
Now, when it comes to using a laser pointer, there are some created to use with monitors. When it comes to finding these types of laser pointers, though, you’re going to want to check in the product description if it’s safe to use on a monitor or TV screen.
We will warn you that many companies like to say that the laser pointer will work on monitors, but it can do more harm than good. A safe way to ensure that your monitor is protected is by only purchasing laser pointers that have been specially created to be used on a TV screen. This way you guarantee that both of your devices are safe and no permanent damage will be done.
Can I Use My Old Laser Pointer?
We wouldn’t recommend that you use any other laser pointer on your TV. There are two reasons for this: either it won’t show up, or the laser could end up damaging the screen.
While you may have read that red laser pointers are safe to use on a screen, that’s only true if they are a specific power level. If the red laser happens to be even just a bit stronger in design, then you will end up damaging the pixels of your TV.
While you may want to use your "old" laser pointer to help draw in the attention of your audience, we recommend that you use these digital laser pointers on your monitor.
An another alternative is to get a handheld wireless mini keyboard. In this way, you can use the cursor to help bring attention to specific facts and graphs.
Some programs you also include the ability to use a clicker, which can draw or underline on the monitor instead of using a beam light. This alternative is an another way when it comes to preserving the longevity of your screen. What’s more is that you’ll find that this method is also a suitable replacement because you’ll have just as much control as a laser pointer presenter, if not more.
So, can you use a laser pointer on a TV screen? The answer is Yes for the digital laser pointers.
And if you’re insisting on upgrading your current chalkboard, whiteboard, or projector to a large screen monitor, then it’s best to keep it safe. Don’t risk ruining it with a traditional laser pointer and frying the pixels up, as this will only result in permanent damage and be distracting in your next lecture. Hopefully, this article has helped you understand if you could use a laser pointer on a monitor.
