This resolution [40] is equivalent to two Full HD ( 1920 × 1080) displays side by side or one vertical half of a 4K UHD ( 3840 × 2160) display. It has an aspect ratio of 32:9 (3. 5:1), close to the 3.6:1 ratio of IMAX UltraWideScreen 3.6. Samsung monitors at this resolution contain built-in firmware to divide the screen into two 1920 × 1080 screens, or one 2560 × 1080 and one 1280 × 1080 screen. [71] Baker AJL, Verrocchio MC.

All of the above-mentioned names refer to the same screen resolution.

Since QVGA is 320 pixels wide and 240 pixels high (aspect ratio of 4:3), the resolution of a WQVGA screen might be 360 × 240 (3:2 aspect ratio), 384 × 240 (16:10 aspect ratio), 400 × 240 (5:3 – such as the Nintendo 3DS screen), 426 × 240, 428 × 240 (≈16:9 ratio) or 432 × 240 (18:10 aspect ratio). As with WVGA, exact ratios of n:9 are difficult because of the way VGA controllers internally deal with pixels. For instance, when using graphical combinatorial operations on pixels, VGA controllers will use 1 bit per pixel. Since bits cannot be accessed individually but by chunks of 16 or an even higher power of 2, this limits the horizontal resolution to a 16-pixel granularity, i.e., the horizontal resolution must be divisible by 16. In the case of the 16:9 ratio, with 240 pixels high, the horizontal resolution should be 240 / 9 × 16 = 426. 6 (426 2⁄ 3), the closest multiple of 16 is 432. DisplayPort 1.3, finalized by VESA in late 2014, added support for 7680 × 4320 at 30 Hz (or 60 Hz with Y′C BC R 4:2:0 subsampling). VESA's Display Stream Compression (DSC), which was part of early DisplayPort 1.3 drafts and would have enabled 8K at 60 Hz without subsampling, was cut from the specification prior to publication of the final draft. [129] Blu-ray Discs are able to hold 1080p HD content, and most movies released on Blu-ray Disc produce a full 1080p HD picture when the player is connected to a 1080p HDTV via an HDMI cable. The Blu-ray Disc video specification allows encoding of 1080p23.976, 1080p24, 1080i50, and 1080i59.94. Generally this type of video runs at 30 to 40 megabits per second, compared to the 3.5 megabits per second for conventional standard definition broadcasts. [14] Smartphones [ edit ]
