INPUT NOT SUPPORTED ACER Monitor

Input Not Supported Error Indicates the inability of the monitor to work on a user-selected or game resolution. On Acer monitors, like others, it occurs either when you turn on the computer, or when you start the game.

Option 1: Error booting the operating system

If the Input Not Supported is displayed when booting Windows, the user will most likely have to spend some effort to restore the computer's performance, since the usual operating system mode becomes unavailable to make the necessary changes. However, if your monitor is connected via VGA, all corrections are reduced to minimal labor costs.

On the monitor, it is enough to find either a separate "auto" button and press it, or first open the "Menu" and already inside the settings to find the "AUTO" function. Thus, you reset all settings to the factory, and the problem will be eliminated.

When connected via HDMI / DisplayPort / DVI will have to do differently.

Windows 10 and 8

In more modern versions of this operating system, the error correction instruction is reduced to the following actions:

1. When you start the computer, try calling the Download Settings menu by clicking either F8 or SHIFT + F8. If it does not work out this from several attempts, use the boot flash drive or feature of the operating system that causes the recovery mode. We will tell about these versions just below, so that those who managed to call "boot parameters" without additional manipulations, immediately could go to the correction.
2. In this menu, you will need to select the option "Enable low-resolution video" by pressing the F3 key. If suddenly it did not help, you can then go to "Safe Mode" (F4).



3. Since often an Input Not Supported error appears on an unknown reason for the user, first of all it is recommended to remove the video card driver and install its last version.

1. In the "dozen" and "eight" there is a function of automatic recovery that runs after three unsuccessful computer boots. Accordingly, to simulate the unsuccessful PC launch, you will have to interrupt this process in the middle. After the boot screen appears with the OS logo, press the "RESET" button on the system unit, and if it is not suddenly not, hold the "Power" for a few seconds to turn off the computer.

Depending on the game, its location will be either in the root folder or in a separate folder of the "Config" / "CFG" type. If nothing of this was found was found, do not forget to look into the system folder "Documents", where the user files sometimes fall like saving - among them the desired document can also hide.
