When you connect your TV via HDMI cable Windows will recognize it as another monitor and will control the display settings for your HDMI connection. In most cases using it as the extended desktop will work fine, issues will arise when you play video on it. Video playing applications can override Windows settings which can lead to strange results on the screen. Here in this guide, we will tackle with reasons and solutions to this particular issue. Solutions provided are not meant to be followed in the way they are presented but as a silent rule, they go from most common one to most rare so it is advisable to try them in the order presented.

FIXING RESOLUTION ISSUES

The first thing when experiencing resolution issues on your TV connected to a PC is to check TV settings. There is very likely a chance that you will need to manually adjust picture settings on the TV itself using TV controls. 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.

Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.

1. Check if BlueTooth is ON

   Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.

2. Restart the BlueTooth device.

   Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.

3. Check power supply

   If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.

4. Restart PC

   Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.

5. Checks BlueTooth device distance from computer or interference from obstacles

   The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.

6. Reinstall or update device drivers.

   Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.

7. Remove and Pair deice again

   if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.

8. Use Windows troubleshooter

   If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.

If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

• While a user is performing the updates, the Windows computer will stop running the updates, and it will show the error code 0x80070490.
• Windows updates will not install any new features and will not install security patches.
• The computer will not continue with the Windows update, and it may revert back to the previous state that the computer was in, prior to attempting the updates.

Error Causes

There is not a lot known about what exactly causes the error code 0x80070490, but it is something critical that makes Windows abruptly stop its updates. It could be caused by a simple glitch in the computer system, or it could be caused by a larger problem. One thought is that the CBS (Component-Based Servicing) manifest can be corrupt. Another thought is that the computer's anti-virus software may be interfering with the computer's ability to perform the necessary updates.

Method One: Creating a new local account

Create a new local account on the computer, and allow administrator privileges on it. Next, move all of your documents and personal files to the new account. Delete the old account (you will no longer be using this) and switch over to the new one. After switching to the new local account, add the Microsoft account to it.

• You will need to open the Registry Editor. Do this by pressing the Windows Key and R, then typing in “Regedit”. After this is typed in, press Enter or click the OK button to start the registry editor.
• When this starts, you will need to navigate all the way to the following key on the left pane:
• HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionAppxAppxAllUserStore After this, find the key that is similar to this: S-1-5-21-1505978256-3813739684-4272618129-1016
• NOTE: this is just an example. The keys will be in a similar format but will not look exactly like this.
• Select all the keys that look like this, and then delete them. After these keys are deleted, close the Registry Editor and restart the computer.

Method Three: Check to see if BITS, MSI Installer, Cryptographic, and Windows Update Services are running

Press the Windows key and R. Then, type in services.msc. After the Services window starts up, find the following services:  BITS, MSI Installer, Cryptographic, and Windows Update Services.
