Here's my problem: I have a MacBook Air (11.6") and a Philips 234EL monitor whose native resolution is 1920 x 1080. However, when I connect the monitor to the laptop with an Apple HDMI cable and a Moshi Mini DisplayPort to HDMI adapter, the maximum resolution I can get is 1600 x 900. The problem seems to be that Mac OS sees the display as a television, not as a computer screen. I've tried with another monitor (Asus VH226H) and another Mini DisplayPort to HDMI adapter (Sandberg). Same results: Max resolution = 1600 x 900. The reason I prefer HDMI is that it carries both video and audio, meaning one less cable (my monitor has sound). Does anyone know how to fix this? Thanks in advance.
