Все способы:
- Способ 1: Обнаружение устройства
- Способ 2: Формат отображения
- Способ 3: Регулировка частоты обновления
- Способ 4: Работа с драйверами
- Способ 5: Настройка BIOS
- Способ 6: Диагностика физического подключения
- Вопросы и ответы: 5
Способ 1: Обнаружение устройства
Обычно второй монитор начинает работать без дополнительной настройки, но если система его даже не идентифицировала, можно воспользоваться функцией принудительного обнаружения.
- Сочетанием клавиш «Win+I» открываем «Параметры» Windows 11, во вкладке «Система» переходим в настройки дисплея,
открываем блок «Несколько дисплеев»
и нажимаем «Обнаружить». Возможно, это поможет распознать второй монитор.
- Если монитор беспроводной, нажимаем «Подключение»,
в появившемся окне выбираем дисплей, а затем подтверждаем сопряжение на самом устройстве.
Способ 2: Формат отображения
Windows 11 поддерживает разные режимы проецирования. Возможно, у вас выбран тот, при котором второй монитор не получает картинку. Естественно, эта функция будет работать, если устройство обнаружено, но оно ничего не транслирует.
- Комбинацией клавиш «Windows+P» вызываем окно выбора типа передачи картинки на экран. В данном случае включен «Повторяющийся» режим, при котором изображение должно быть одинаковое на обоих экранах, а значит, проблема не в этом.
Но если у вас выбран режим «Только экран компьютера» или «Только второй экран», переключитесь с них, так как они предусматривают передачу изображения лишь на один из мониторов.
- Альтернативный вариант – открываем настройки дисплея, как мы это делали в первом способе, в верхней части страницы кликаем кнопку под изображением экранов
и переключаем режимы.
Способ 3: Регулировка частоты обновления
Вообще, два монитора с разной частотой обновления могут работать одновременно. Но, возможно, ваша видеокарта не способна обработать установленную герцовку или само устройство отображения данных, согласно своим характеристикам, ее не поддерживает. В этом случае можно подключится к другой видеокарте, если она есть, либо попробовать изменить значение частоты обновления, например снизить его, если стоит самое высокое.
- Снова открываем блок с настройками экрана, прокручиваем страницу вниз и кликаем «Расширенные параметры дисплея».
- Сверху выбираем второй монитор, а в блоке ниже меняем значение частоты обновления.
Способ 4: Работа с драйверами
Иногда недостаточно просто подключить монитор к видеокарте, так как и тому, и другому устройству для нормального взаимодействия с системой нужны драйверы. Возможно, в этой области как раз и кроется проблема.
- Кликаем правой кнопкой мышки «Пуск» и открываем «Диспетчер устройств».
- Ищем вкладку «Мониторы», разворачиваем ее и, если кроме основного дисплея в ней отображается второй монитор или хотя бы неизвестное устройство, значит, Виндовс 11 все же их видит, но из-за устаревания драйверов или их отсутствия не передает картинку. Поэтому кликаем по устройству правой кнопкой мышки, в контекстном меню выбираем «Обновить драйверы»
и кликаем «Автоматический поиск».
- Если подходящего ПО нет, можно запустить поиск в Центре обновления Windows.
- Если это не помогло или второй монитор вообще не отображается, значит, возможно, дело в драйверах видеокарты. Например, установлена версия, которая не поддерживает подключение второго монитора. Поэтому открываем блок «Видеоадаптеры» и таким же образом пробуем обновить драйверы видеокарты.
Впрочем, ограничиваться поиском программного обеспечения только с помощью службы «Windows Update» не стоит. Довольно распространены случаи, когда производитель выпускает для своих устройств «свежие» драйверы, но они далеко не сразу появляются на серверах Microsoft. Поэтому поищите актуальные версии ПО самостоятельно, используя способы, которые описаны в отдельных статьях на нашем сайте.

Способ 5: Настройка BIOS
Если компьютер оборудован двумя видеокартами – интегрированной и дискретной, и к обоим подключены мониторы, откройте «Диспетчер устройств» и посмотрите, сколько видеоадаптеров отображается. Если один, значит какая-то графическая карта, скорее всего, отключена в системе BIOS. Конечно, на разных материнских платах процесс переключения может отличаться, но основной принцип подробно описан в отдельных статьях на нашем сайте.

Способ 6: Диагностика физического подключения
Проверьте все кабельные соединения на наличие повреждений. Если используются переходники, попробуйте подсоединиться без них или используйте другие, ведь такие аксессуары, особенно если они дешевые, как раз могут быть причиной неполадок. По возможности попробуйте подключить другой монитор или телевизор. Также отключите на время все внешние периферийные устройства (флешки, диски, колонки, принтеры, проекторы и прочее), которые в данный момент не нужны вам для работы.

- Inspect the signal cable connection – Check that the cable connecting the monitor to the graphics card is securely plugged in at both ends.
- Reconnect the signal cable – Disconnect the video cable from both the monitor and the computer, wait for 60 seconds, then reconnect it firmly.
- Swap the video cable – Use a different cable to rule out a faulty or incompatible one. Even small issues, such as bent pins or poor shielding, can screw up the signal.
- Check cable specifications – Ensure you’re using a cable that meets the monitor’s requirements. For example, DisplayPort 1.4 or HDMI 2.0/2.1 may be necessary for high resolutions or refresh rates. Refer to the manufacturer’s documentation for compatibility guidelines.
- Try different video ports – If your monitor and graphics card support multiple input and output ports, test each one to rule out port-specific issues.
- Connect the monitor to another computer – This will help determine if the issue lies with the display itself.
- Test a different monitor – Connect a known working monitor to your computer to check if the problem is related to your system’s graphics card or drivers.
- Disconnect all peripheral devices – Unplug printers, cameras, USB drives, and other accessories to eliminate potential conflicts.
- Surface devices using a docking station – Bypass the dock and connect the monitor directly to the device. This helps identify whether the dock is the cause of the problem.
- Update your monitor’s firmware – Although rare, outdated firmware can cause compatibility or performance issues. Check your manufacturer’s website for firmware updates and installation instructions.

- Select an option to answer the question.
- Click the Yes button.
- Restart the device.
Once you complete the steps, Windows 10 should start rendering content on the external monitor.
Update graphics driver with manufacturer control panel
The operating system can automatically install drivers for most graphics adapters, but the drivers available through Windows Update are usually not the most recent. If you need to install the latest driver, companies like NVIDIA, AMD, and Intel offer tools to quickly update to the newest version, which may help fix external display problems.
Check out these links to download the drivers, depending on your manufacturer:
- Intel Driver & Support Assistant

- AMD Radeon Software Adrenalin Edition
If you want to use the manufacturer’s control panel application, the installation is simple. You only need to download and double-click the installer using the links above. Then, follow the on-screen directions to complete the setup and check for updates.
Alternatively, you can download the drivers directly from the manufacturer’s support website using their recommended instructions. You can use the links below to find the drivers:
