You can turn the disc around and visually check the disc for fingerprints and scratches which can be fatal for disc playing, alternatively, you can try to play the same disc on another device and if it fails there also it is not the disc, it is your drive. So if it is no issue with the disc let's see that seems to be a problem with the drive. The common thing that could stop disc reading are cables, check all connections and cables in the back of your device to be sure that everything is plugged in correctly and nicely. After checking cables if the issue persists lens cleaning is the next step. Over time lens from the Blu-ray, the device becomes dirty and dust accumulates on it, there are special cleaning discs on market made especially for this purpose, to clean the dirty lens of optical devices. If you have one put it in and clean your lens. After lens cleaning with a specialty disc, a good idea would be to use compressed air in a can to reduce the dust inside so no excess dust will accumulate quickly again on the lens itself.

So the device is cleaned and checked and still no disc playing?

Update firmware first. In order to accomplish this visit your device manufacturer's website and follow instructions there on how to upgrade firmware. If this did not helped also update or reinstall device drivers. Go to device manager and update drivers for your device by right-clicking on it and choosing update driver. If none of the things helped, go to command prompt as administrator and type in SFC /scannow, leave the process to finish, and reboot.

You have probably heard a lot of good things about gaming mice, how they are better feeling, better in any way possible and it is all true, everything you heard is actually true, they are superior in any way to a regular mouse but with one big disadvantage, and that would be the price. While you can find a regular mouse for pocket change, a gaming mouse is in comparison very expensive even for entry-level ones.

In this article we will explore all advantages and compare it with the regular one so you can come up with your own conclusion about do you really need one for yourself or if you are fine with regular.

Price

As stated price is one factor that does not favor gaming mice. Regular mouse for a personal computer goes around 10 or 20 USD, while entry-level in gaming one will be 40 USD and can go up to 250 USD, this large gap in price is usually determining factor why people pick up regular one. If you are on a really tight budget go for the regular one, but if you can afford a gaming one get it without second thoughts.

Software

This is where you will see the big difference between mice. Regular ones when connected are recognized and the driver is automatically installed and you can use it, same goes with gaming ones but with one big difference, you have an option to install additional manufacturers' software specially tailored for your mouse. In the application, you will be able to access some features that are specific to the mouse model that you could not set in typical Windows mouse properties. Beside more options software can also have features like setting your profiles and saving them to be recalled when you need them on the fly.

Sensitivity of mouse

The sensitivity of the mouse is measured in dots per one inch or short DPI, this is directly shown on your screen by how fast your mouse can move, higher sensitivity means your mouse will move faster across the screen and lower means it will move slower. All gaming mice come with buttons and settings that will allow you to change DPI on the fly and you can choose precise DPI settings in the software.

The regular mouse comes with DPI around 800 and goes to 1200 typically and does not have usually the option to change this while gaming mice start at 400 and can go as high as 26000 with the option to change it. Some regular mice can have only 1 option of DPI, usually very cheap ones.

Polling rates in mice

Pooling rate is the measurement of how often your mouse reports where it is positioned on the computer. The higher the pooling rate, the more responsive your mouse will be and vice versa. It is measured in hertz (Hz) and regular mice have them around 125Hz that is enough if you are using a computer for office, internet, and mail work.

If you are working in design or gaming you will need more than 125Hz polling rate, luckily gaming mice come with a minimum of 500Hz as an entry point and some hi-end models are going as far as 8000Hz. This very high pooling rate will get some extra load on your CPU but the mouse itself will be maximally responsive and will respond even to the smallest moves.

Ergonomics

Regular mice are well just mice, they are typical shape and size, gaming mice are made with ergonomics in mind. How they are made for extensive daily use of several hours per day they are constructed in a way to offer a pleasant and pain-free experience.

If you work on a computer for long periods of time consider gaming an ergonomic mouse since it will take the strain from hands and place them in a more natural position.

Macro keys

Gaming mice most of the time come with more keys compared with regular ones and good thing is that via its software you can tie certain actions to these extra keys making work or gaming more pleasant and quicker.

Components and material quality

In order to make regular mice more affordable and cheaper materials and quality of components had to suffer. Gaming mice have millions of guaranteed clicks by companies that make them before they break and regular ones usually do not guarantee a single one. This is due of course quality of materials that have been used in constructing these devices.

In the long term, if you use a gaming mouse for typical daily tasks it will outlive your regular one and on the side offer you more pleasant and responsive use along the way.

On older models of TV, there is an overscan option which can lead to different resolutions and screen sizes. Overscan is a technology that was used in order to help content creators to deliver consistent pictures on different screen sizes and aspect ratios but how technology has advanced and everything including aspect ratio was standardized overscan itself has become a relic of the past. If you are unable to access or see edges of your desktop on the TV screen it is very likely that overscan is the issue. In order to fix this be sure to select HDTV's aspect ratio to fit the screen setting in the picture setting. Sadly finding this option on your TV will be different from manufacturer to manufacturer and even from model to model of the same manufacturer so we can not cover all models but in most cases option is located under picture settings or advanced options. Sometimes you will face even different overscan settings instead of classic ft to screen options, in this case, experiment with the setting until you find one which will work. If you have it, find settings in the user manual of your TV. Luckily you have managed to find the proper option on your TV set and have chosen the right aspect ratio for display. If everything works ok there is no need for the next step but if you experience a different resolution than desired on your TV follow this next guide on how to change the resolution of the TV on your PC.

1. Press the ⊞ Windows and type Change Display Settings. Click on the top result.
2. Once the Display Settings App opens, you’ll see two screens (or more if you’ve got multiple HDMI outputs connected). Make sure you select the right display for the HDMI TV before making any changes. You can do this by clicking on Identify.
3. You’ll see the number from the screenshot above displayed on the monitors for a brief period. Depending on which screen is set to your primary display, make sure you change the settings for the HDMI monitor.
4. Select the HDMI monitor from the available displays.
5. Scroll down until you see the current resolution settings for your HDMI monitor.
6. You can change the resolution settings and test different values that match your HDMI TV’s configuration.
7. Once you change the setting, Windows will apply the new resolution for a limited time and revert if you don’t accept the new setting.
8. Once you’ve found the best resolution for your TV, select Keep Changes to keep the new resolution.

You are all set now, make sure that you have the latest drivers on your system and enjoy using your TV as a second monitor.
