I have a Lenovo T440p with an Intel 4600 graphics card, and I want to set my resolution to 1080p. When I connect my TV and clone both displays, the laptop screen adapts to the higher resolution and displays 1920x1080. However, I have been unable to find a way to do this without the TV being connected. The native resolution is 1366x768, and 1080p is not an available setting. I have tried custom resolutions, but they do not allow it, saying the hardware cannot do it. I have also tried 'Detect' and other methods, as well as CRU and going into the registry. I understand that there is no reason why I cannot output a high resolution into any screen, but it would result in a poor image quality. All I want is smaller icons, taskbar, etc., more space, and I do not care about the actual pixel resolution or if I cannot even read the text under the icons.
My first idea was to use an HDMI emulator that would be 1920x1080 and then clone that "virtual" monitor, which is not physically there, to the laptop screen. Does anyone know of a way or a simple software, etc. that can help me achieve this?
