Smartphones with 1080p Full HD display have been available on the market since 2012. [15] As of late-2014, it is the standard for mid-range to high-end smartphones and many of the flagship devices of 2014 used even higher resolutions, either Quad HD (1440p) or Ultra HD (2160p) resolutions. Here’s a cheat sheet for display resolutions, if you do not want to get into the technicalities: Resolution For a list of resolution standards in computer monitors, see Graphics display resolution. Pixel aspect ratio (PAR) The horizontal to vertical ratio of each pixel. Storage aspect ratio (SAR) The horizontal to vertical ratio of solely the number of pixels in each direction. [note 1] Display aspect ratio (DAR) The combination (which occurs by multiplication) of both the pixel aspect ratio and storage aspect ratio giving the aspect ratio as experienced by the viewer. Computer and handheld screens To further uncover long-term outcomes of perceived PA behaviors during childhood, the relationship between exposure to PA and HRQoL domains was examined. We chose to adopt the SF-36 as a well-established measure developed in the International Quality of Life Assessment (IQOLA) project [ 54] since HRQoL is a topic in which cultural beliefs, behaviors and bias may affect the responses of participants, raising the issue of cross-cultural equivalence of translated measures [ 55, 56]. The IQOLA project was launched with the goal of testing the cross-cultural applicability of the SF-36 with a team of investigators from 14 different countries. The findings from several studies demonstrated that the Italian version of the SF-36 had a high level of equivalence with the original version developed in the United States [ 42]. In this study, reliability of the WHO-3 was established with a Cronbach’s alpha of 0.62. Moreover, the WHO-3 showed a significant negative correlation with the BDI-II ( r = −.53, p< 0.01). Data analysispossibly DPAL or F-PAL [ citation needed] It is the 4:3 equivalent for PAL (576 lines) on a display with square pixels. Coates AA, Messman-Moore TL.

The survey consisted of demographic questions (i.e., age, gender, level of education, employment, and information about parents) and a series of standardized measures, three of which were examined for this study. Baker Strategy Questionnaire (BSQ)

Chi-square analyses were conducted to examine whether any exposure to PA behaviors (PA vs. No PA groups) was associated with greater likelihood of being above the clinical cut-off on the BDI-II, the 6-item version of the BDI-II, and the WHO-3, as well as with greater likelihood of being below the established threshold on SF-36 domains. For these analyses, dichotomous scores for all measures were selected. The name comes from having a quarter of the 640 × 480 maximum resolution of the original IBM Video Graphics Array display technology, which became a de facto industry standard in the late 1980s. QVGA is not a standard mode offered by the VGA BIOS, even though VGA and compatible chipsets support a QVGA-sized Mode X. The term refers only to the display's resolution and thus the abbreviated term QVGA or Quarter VGA is more appropriate to use. High Definition 1080p TV: Why You Should Be Concerned.

In the mid-2000s, when the digital HD technology and standard debuted on the market, this type of resolution was often referred to by the branded name HD ready or HDr for short, which had specified it as a minimum resolution for devices to qualify for the certification. However, few screens have been built that use this resolution natively. Most employ 16:9 panels with 768 lines instead ( WXGA), which resulted in odd numbers of pixels per line, i.e. 1365 1 / 3 are rounded to 1360, 1364, 1366 or even 1376, the next multiple of 16.
