Why Do Computer Beep Codes Exist
Before we go on to decipher what these particular beep codes mean, it is essential to understand why they pop-up during the start-up process. The process that we will need to look at for this is called POST or Power-on-self-test.
What is POST? Essentially, each time a user turns on their PC, the BIOS gathers information about the major system components and performs a special diagnostic test called the Power On Self Test to make sure that each component is functioning properly. While the entire process is more complicated than that, the thing to keep in mind is that its a kind of a diagnostic test for your computer. So if the BIOS identifies a hardware problem during this test, it will display an error message on the monitor called a POSTCODE.
However, if the failure occurs in the POST process before any display signal is sent, the problem cannot be shown as a visual signal. And this is where motherboard beeps come into the picture. Being an audio signal, beeps can take information from the BIOS and turn it into something we can understand, even when the BIOS cant access the video card.

How To Display A Computer Image On A TV Or Projector
Projecting your computer to a larger display is a great way to present information, watch movies with a group, or play couch co-op games. Most modern televisions and projectors have one or more ports that allow them to receive and display an image generated by a computer. Both desktop and laptop computers are capable of connecting to a TV or projector, provided that they have the appropriate cables.

Beep Code Alternatives: Motherboard Led Debugging
In the recent past, new categories of debugging tools have emerged, and one of the most popular of them are LED indicator lights that check for hardware failure. A popular iteration of this method is used by MSI in some of their motherboards and is called the EZ debug LED.
In supported motherboards, LED lights are placed on the bottom, next to specific texts like BOOT, VGA, or CPU, and in principle, will act as warning lights if something goes wrong.
These LED lights will blink on and off every time you start your PC, which means just turning them on is not a sign of hardware failure. But if they turn a stable red or white, depending on the hardware manufacturer, it signals something has gone wrong with that particular part.
What we need to keep in mind though is that each motherboard LED tells you where the problem has occurred, but not necessarily what it is. So, they still require some guidelines to be understood properly. In this context, what are the ways in which we can interpret these LED lights? The LED lights in MSI motherboards are typically divided into 4 parts, and each of them is appointed to specific areas of the motherboard, so if any of them goes off, it could mean the following things:

How To Wirelessly Mirror A Windows Laptop To An Hdtv
In all Windows 10 and Windows 8.1 computers, including laptops, there’s a built-in capability for mirroring your screen on a television called Miracast or Wi-Fi Direct. There are a few things to keep in mind, though:
- Both the television and the laptop need to be connected to the same network.
- Your laptop and TV both should be current and completely updated with any operating system patches or security updates.
- It is possible that a laptop that was upgraded from an older version of the operating system may not support Miracast .
- While most HDTVs will support Miracast, there are some that do not, and you will not be able to mirror your laptop to those TVs using Miracast unless you buy a separate Miracast dongle.
As long as your computer and your TV support Miracast, mirroring your TV should be a simple process.
Make sure both your laptop and your TV are connected to the same network and then go to the Windows logo button > Settings> Devices.
To get to Settings you could use the keyboard combination Windows Key + I .
In Bluetooth & other devices click Add Bluetooth or other devices.
An Add a device dialog box opens. Select Wireless display or dock.
A list of available devices appears, select the television you’re trying to connect to.
How To Show One Desktop Screen But Use Another
In fact, you can show different content on your laptop vs your projector / TV.
I have my computer set up with an extended display so its like having two connected computer screens side-by-side. If I drag my mouse far enough to the side on one screen, itll jump over to my second screen.
It takes a little bit of time to get used to, and sometimes, it can be hard to find the mouse, but I like having the extra screen real estate.
Using an extended desktop means that I can work on things and get applications ready on my computer screen before showing it to students on the screen which is projected. It means I can quickly switch from a PowerPoint presentation to a Google doc to a YouTube video to another computer program just by clicking and dragging.
PRO TIP: By the way, if you do school assemblies, showing a different screen to the audience is a great way to keep them engaged. Nothing loses a crowd more quickly than when you have to open the file, and then load the video, etc. Just have everything ready to go on the laptop screen, and then when you need it in the school assembly, drag the window over onto the big screen. Back in the day, I used to have grade 7 and 8 students control the laptop so then I could focus on presenting to the classes.
It also means that I can show instructions to the students on the computer projector, but open up a confidential email or student file on my private computer screen.

Im Having Trouble Getting My Devices To Connect Whats Happening
Check your internet connection if youre trying to mirror your device to another device, and it wont connect. More often than not, the problem occurs because youre connected to two different bands on the same network. Simply go into the WiFi settings on your device and ensure they are on the same band.
Of course, if youre using one of the HDMI cables weve mentioned above, check that all of your ports are working and the cable is fitted properly. Some devices may require you to turn on developer options before casting your screen, so check with the manufacturer to verify if the image doesnt immediately appear.
What Do Motherboard Beep Codes Mean
The beep codes can vary a lot from BIOS to BIOS, and it can be a bit tricky to figure out exactly what they mean. But, in general, one quick beep means that everything is working fine. Though, if you hear anything other than a single happy start-up beep, you might need to check your motherboard manual to decipher the beep code and figure out what is wrong with your PC.
The aspect that makes this task particularly confusing is that motherboard makers are not necessarily the same as BIOS makers, which means thebeeps are not bound to your motherboard manufacturer but to your BIOS firmware. And well, unfortunately, there isnt a standardized beep code regardless of what BIOS firmware is in your machine.
This signifies that even though there arent too many BIOS manufacturers out there, there isnt a single standard that they all use, leading to each of them having their own set of beep codes. They might use different patterns and beep lengths some might be really short, some might be long, and some might even have varying tonality. So, the same beep sound on two different computers is possibly used to express two entirely different problems.

Wirelessly Mirror Or Extend Your Windows 10 Laptop To Your TV
In closing, most modern laptops can physically connect to a television using either USB-C or HDMI. Some have a mini-HDMI port or a DisplayPort connection. Adapters provide the best functionality since you can utilize different video source inputs. However, a cable such as one with USB-C to HDMI does the job fine. Furthermore, you have the wireless option if your TV supports Miracast. The only thing left is to decide if you want to mirror or extend your current display, which both macOS and Windows support.
Another possibility is mini-DisplayPort: this too can be connected to an HDMI television with the right cable or via a simple adapter. The signals can also travel over a high-speed Thunderbolt bus, so you might be able to connect your TV to a Thunderbolt port on a Macbook or iPad.
HDMI and DisplayPort connections can carry sound as well as vision, so a single cable should do everything required, but you may need to manually switch audio devices to get audio to play through your TV. You can do this by right-clicking on the volume icon in the Windows system tray, selecting Playback Devices from the pop-up menu, selecting the appropriate device, and clicking Set Default.
How To Mirror Your Laptop Using Cables
If you don’t have a newer laptop or a smart TV, you can probably still mirror your laptop to your TV, you’ll just need to use an HDMI cable to do it.
If you’re using an older laptop, you may need to use a VGA cable. The problem with VGA cables is that they don’t carry sound, so you’ll also need an audio cable if you want to hear the sounds your computer makes. Also, check your TV to make sure it has VGA ports. If not, you will need to purchase a VGA adapter, too.
All you need to do is connect the HDMI cable to your laptop and to your TV. Then, using the remote on your TV, select the input that corresponds with where you plugged the cable in.
On Windows, you can then use the keyboard combination Windows Key + P to open display settings and choose how you want to display/mirror your laptop screen.
On a MacBook, you may not have HDMI connections so you’ll need an adapter for a mini DisplayPort or a USB-C. Once connected you can go to System Preferences> Display to adjust display settings if necessary.

Idea #: I Have Five 32 Monitors Spread Around My Room So Students Can Present From A Big Screen
Our school had pods of Google Chromebooks that you could use to teach in the classroom. So if I could get 8 chromebooks / teacher laptops / desktops, I would split the class into groups of 2-4 students, and give each group a device. They would connect the device to a TV monitor, and mirror the display. This way students could present to a small group and everyone could see the screen.
Way better than trying to cram 4 students around a single chromebook screen, but required some Black Friday shopping to get some good deals on TVs.

Will It Even Work
The short answer: Yes. You may need a special cable, depending on your PCs outputs and your HDTVs inputs, and youll need to check a couple of settings, but you shouldnt have too much trouble hooking most modern PCs up to most modern HDTVs.
Modern HDTVs have HDMI outputs. Some older HDTVs have DVI inputs, and some even have VGA inputs specifically designated for PC use. If your graphics card has an HDMI output, youre good to go: Just use an HDMI cable to connect your PC to your HDMI.
All modern graphics cards include at least one HDMI port .
If youre using an older graphics card or motherboard that only has a DVI output, you can snag a cheap DVI-to-HDMI cable and plug it into your HDTVs HDMI output. Amazon sells Remove non-product link. Although some older HDTVs and some older computers only have VGA inputs/outputs, they arent not an ideal choice. VGAs an analog signal that will give you a far fuzzier, lower-resolution image than youll get with an HDMI or DVI cord.
Bottom line? Try to stick to HDMI if or DisplayPort-to-HDMI connections if its possible. Its the easiest solution.
