After we’ve talked about different ways you can hook up your computer with TV and mirror the monitor content on your TV, and other technical aspect of doing this, we feel it’s important to talk about the challenges usually experienced in getting the correct output. Take a cup of coffee or juice, get yourself relaxed and read on. ……..
If your PC is not having the HDMI output and only work with DVI
What you should do here is to get a DVI to HDMI cable and you’re good to go but it’s important to know that, not all graphics cards can transmit sound through the DVI output; this makes your laptop brand and specification another factor.
To overcome this, you’ll need another cable for audio transmission. This addition cost is worthwhile than buying a new PC because of this. This cable is much needed if you don’t want to use DVI and HDMI to avoid the old VGA connector. Here you can also check if your TV still has a corresponding input.
The audio output on your laptop is usually based on a 3.5 mm jack; check your TV and you’ll find either the same jack or red and white RCA Jack.
Take away: If you’re not able to use the HDMI cable, you can as well work with HDMI-over-wireless solution, such as the Celexon WHD30M, whereby the HDMI signal is transmitted at maximum high definition via radio.
We’ve noted that things work very well if both the laptop and TV are not far from each other, so that the signal can be easily received.
How does Cable Connection works & How to fix my TV when it says no signal
There’s no much to do here as the HDMI cable connection works simple. Power on your laptop and TV, plug in the cable appropriately to the outlets and the two devices would start working, provided the settings on your Smart TV is correct; it should receive the signal immediately and there would not be problem of connecting the hdmi cable and no signal.
Sometimes, the TV product, like samsung tv may fail to recognize your hdmi cable, in this case, if the hdmi port is not working on tv, you need to change the cable and ask the seller before buying it. In other time, it may also be the hdmi port that’s not working on the PC. I’ve experienced thin on Asus computer.
If these are not the problem and the aforementioned tips we provided do not work, activate the necessary output devices in the display drivers. If this does not help, try to update your computer OS version. You can do this via Windows Update if it’s windows CP and also update the video card drivers with new ones if possible.
You can get this on the official website of the manufacturer of your video card. If you have an AV receiver between your PC and TV, you should remove it from the network first, at least for testing purpose, to get to know what causes the problem.
Make sure that your TV is switched to the correct signal source. Most TVs have multiple connections and an internal tuner for TV reception. You may need to make sure that the TV shows the signal that it is now connected to the HDMI socket connected to the PC.
After that, check to see if your laptop has detected the TV. You should see that a new device has been detected in the tray, usually at the right corner of the computer screen or go to the PC settings under “System > Display > Screen”. If there’s no connection, disconnect everything and reconnect the cable.
HDMI cable is Connected between Laptop and TV but No Picture
If there’s no picture on your laptop when HDMI cable has been connected to the TV, or showing blurry text or fuzzy , it’s much likely the picture resolution settings is not properly done or it’s set to have some effects, like no picture or blur picture etc. Also check to see that image resolution is in pixels and frequency is in Hertz.
If you check your TV manual, you’d see the description as regards the TV resolution and frequencies limit and if you can find the manual or you bought a fairly used TV, you can try the default setting such as 1,920 x 1,080 pixels at 50 or 60 Hz.
Graphics adapters from AMD, Intel and Nvidia have their own programs for these settings which you can find in the taskbar (near the time display) or on the Start menu. Otherwise, use the Windows settings (“System > Display > screen”) for image resolution. For the repeat frequency, see “System > Display > Screen > Advanced display Settings > Display adapter Properties > Monitor”.
Note: You can just right click anywhere there’s no icon on your desktop; The shortcut menu which pop up get easily get you to the graphics settings program of the computer manufacturer and to the Windows settings as well.
TV connected to PC, TV cuts off edges of PC Screen
Some LCD TV’s products like Panasonic, Samsung, LG etc sometimes have picture size problem, off the top and bottom of picture, left side of the screen etc , especially with windows 7,10, Intel graphics.
How do you now adjust the TV screen picture size to fit screen?, to adjust the desktop size and position, you can just disable the feature commonly called ; you can also do this from the laptop, but the best seems to be on the TV picture settings as just described.
However, each manufacturer designates this function differently. Look for terms like “picture mode”, “p. Mode”, “p. Size” on your TV remote control or on the on-screen display. For example, the setting you call above means “true pixel”, “true Scan”, “full Pixel”, “unscaled”, “Screenfit”, or just “PC”.
If the TV is not set correctly, you may be able to correct it with the overscan effect using the settings of your video card.
For example, the Nvidia drivers offer a feature that allows the image to be displayed on the area displayed by the TV.
The Screen Refresh Rate
You need to check your monitor refresh rate and change the refresh rate if possible. However, if you find it difficult to change the monitor refresh on old windows like 7 and 8, you can update to the newer ones like windows 10. The software supplied by most graphic manufacturers is faster.
HDMI connected to PC but no sound from TV
This is usually not wimdowor Mac problem, if picture is showing and there’s no sound on TV, This is how to get sound from laptop to tv with hdmi, go to your computer system Control Panel, under sound card settings, make sure you have selected HDMI as the sound output device. That is the basic requirement.
In addition, it may be necessary that you specify a specific format, for example Stereo. Here, too, you may need to take a look at your TV manual guide to know the format that’s compatible with your TV.
