- Hello Admin, in short, this is the case: I bought a new TV with a screen resolution of 1920×1080, connected the TV (second monitor) to the computer via HDMI, everything is basically fine, the picture is on the TV, but I can’t set the resolution on the monitor correctly. The computer monitor does not support the maximum resolution of a 1920×1080 TV. The maximum that can be set on my monitor is 1280×1024. Therefore, the resolution on the TV is normal 1920×1080, and on the computer monitor everything is a little flattened. In principle, the resolution on the monitor is not important to me, the most important thing is that everything was fine on a large TV, but still, maybe there is some solution to the problem?
- Maybe you can help me, I have a simple system unit on which there is a card with an HDMI output and there is a TV with an HDMI input. I want to use the TV at times instead of the monitor, but many do it, for example, to watch movies, which I have a lot of. I really want to see all these films on my TV, but it doesn’t work out, or rather it turns out, but not really. With me connecting the TV to a computer via HDMI there is no sound, but the picture is very good. Windows 7 operating system, tried several HDMI cables, maybe it’s not about them, but about the settings of the operating system?
How to connect a TV to a computer via HDMI
For example, take a Samsung TV, a not entirely new 4 series (type LED), bought several years ago, but it already has two connectors for connecting HDMI devices.
The computer that we will use to connect to the TV was also purchased about three years ago, it has an Nvidia card and also with an HDMI connector.
As I said, there are two HDMI connectors on our TV. On the TV turned off, connect the HDMI cable to the HDMI 2 connector,
the opposite end of the cable is connected to the HDMI connector of the card of a desktop computer. The computer, in turn, is already connected to the monitor (also Samsung SyncMaster 971P) with a DVI cable.
Turn on the computer and TV. There may not be an image on the TV at once; instead, we see the following message: “Cable is not connected” “Check cable connection and source parameter” or “Weak signal or no signal”
On Samsung TVs, to display a list of all available sources, you need to press the button on the Source remote control.
A menu appears on the TV, in this menu, using the remote control, select the HDMI 2 connector,
then on the remote control press the button Confirm selection.
Now, on our TV, an exact copy of the desktop of our computer should appear. But again there is nothing, the same error appears on the black screen. So we go to the “Screen Resolution” settings. Right-click on the desktop and select “Screen Resolution”.
As you can see in the window that appears, the second (2) Samsung SyncMaster 971P monitor is set as the main screen, and in the “Multiple Screens” option we set “Display the desktop on only 2 monitors”, that’s why the image is only on the computer monitor but it’s not on the TV
We bring everything to this state in this window. Select parameter
Multiple screens: “Duplicate these screens”
In the “Screen” parameter, “Multiple Monitors” is automatically set, click Apply and OK.
The desktop of our computer appears on the TV.
The resolution of our small Samsung TV is 1366 x 768. If your computer monitor supports this resolution, it means that it will be set to the same resolution 1366 x 768 automatically. If not, then either the TV or the monitor will have the wrong resolution. For example, my Samsung SyncMaster 971P monitor has a maximum resolution of 1280×1024. When using a TV and a computer monitor at the same time, the main thing for me is to set the resolution on the TV correctly, otherwise why did I connect it then. I set 1366 x 768 resolution on the Samsung TV, the image is perfect.
And on a computer monitor, such a resolution of 1366 x 768 looks like this.
And nothing can be done here. If you need a perfect picture on a TV and a computer monitor, then they should support the same screen resolution, that is, have the same characteristics.
Equipment and soundSound
If you don’t have anything in this field, right-click on an empty space and select “Show disabled devices” in the menu that appears. “Show connected devices”
Now we look at the name of our TV, in my case it’s Samsung, you need to turn it on, and turn off the rest. Right-click on Realtek and select Disable.
