    1080p is 1920x1080@60Hz.

    Any 1080p content on a 16x12 monitor would be scaled down to 1600x900.
    That isn't to say it won't look good, there'll just be black bars at the top and bottom.

    But wouldn't the fact that it's 30 FPS make it 1080i?

    1080p = 1920*1080 progressive Scan
    720p = 1280*720 Progressive Scan

    So yes your monitor is "HD" it supports 1280*720. But not 1920*1080.

    No. Frames per second and progessive v. interlaced are totally separate things.

    When each frame contains 100% of the image, it is progressive. When each frame contains either even or odd lines (half) it is interlaced.

    1080p @30fps is definitely a standard 1080p format. Remember that most films are based upon 1080p @24fps.

    If you multiply these resolutions out to get # of pixels, you'd see that 1600x1200 and 1920x1080 are almost identical in terms of resolution. Assuming square pixels, the aspect ratio is different, but that doesn't change the overall resolution. 1600x1200 is definitely HD and just barely below 1920x1080.

    But the actual image doesn't get resized to 1600x1200, it gets scaled down until the width of the image equals the width of the screen, to preserve the aspect ratio: 1600x900 pixels.

    From Wikipedia, the free encyclopedia




    1080p is the shorthand name for a category of display resolutions. The number "1080" represents 1,080 lines of vertical resolution,[1] while the letter p stands for progressive scan (meaning the image is not interlaced). 1080p is considered an HDTV video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080, or 2,073,600 pixels in total. The frame rate in Hertz can be either implied by the context or specified after the letter p, such as 1080p30, meaning 30 Hz.
    1080p is sometimes referred to in marketing materials as "Complete High-Definition". However, 2K/4K digital cinema technology is commercially available, and ultra-high definition video is in the research phase.
    In addition to the meaning of 1080p as a display resolution, 1080p is also used to describe video equipment capabilities. Use of 1080p and the closely related 1080i labels in consumer products may refer to a range of capabilities. For example, video equipment that upscales to 1080p takes lower resolution material and reformats it for a higher resolution display. The image that results is different from the display of original 1080p source material on a native 1080p capable display. Similarly, equipment capable of displaying both 720p and 1080i may in fact not have the capability to display 1080p or 1080i material at full resolution. It is common for this material to be downscaled to the native capability of the equipment. The term "native 1080p capable" is sometimes used to refer to equipment capable of rendering 1080p fully.
    My LCD monitor has a native resolution of 1920x1200 and is considered HDMI capable.Audio signal PCM, DVD-Audio, Super Audio CD, Dolby TrueHD, DTS-HD Master Audio Video signal 480i, 480p, 576i, 576p, 720p, 1080i, 1080p, 1440p, 1600p, etc.
