Reblogged from MaximumPC Posted 05/18/10 at 06:03:33 PM by Dr. Raymond Soneira By now, you’ve surely seen ads for Sharp’s Quattron four-color technology. George “Mr. Sulu” Takei dons a lab coat, and fawns over Sharp’s introduction of a yellow primary-color sub-pixel to the traditional three-sub-pixel, RGB primary-color arrangement. According to Sharp, this results in “expanding the color gamut and faithfully rendering nearly all colors that can be discerned with the unaided human eye, especially golden yellow.” If you have read this far, you already know that Quattron is just another shameful marketing gimmick. HDTV television and movie content is produced and color-balanced on three-color displays that are accurately calibrated to Rec.709. Sharp’s fourth primary color is yellow, and there isn’t anything for it to do because yellow is already being accurately reproduced with mixtures of the existing red and green primaries. More importantly, a Quattron display can’t show colors that...

Reblogged from MaximumPC Posted 05/18/10 at 06:03:33 PM by Dr. Raymond Soneira Color gamut, which is the range of colors that a display can produce, is undoubtedly the most misunderstood and exploited spec—precisely because it’s natural to believe that the range should be as large as possible. While that’s true for most specs (even when they’re exaggerated), it’s definitely not the case for the color gamut. The color gamut that you want on all of your PC monitors, laptops, HDTVs, and even smartphones is the same color gamut that was used when the content you’re viewing was created. If a different gamut is employed, you’ll see different colors than you’re supposed to see. Virtually all consumer content is created using industry standards that specify the exact color gamut to be used. For computers and digital cameras it’s sRGB. For digital HDTVs, it’s called ITU-R BT.709 (often referred to as Rec.709). Fortunately, both of these standards specify the same exact gamut. Yes, there are...

Reblogged from MaximumPC Posted 05/18/10 at 06:03:33 PM by Dr. Raymond Soneira All displays show artifacts of one sort or another when their screen images change rapidly. It’s most easily detected with moving objects, or when the entire screen moves due to camera panning. In many cases, it’s not the fault of the display. Rather, it arises somewhere in the signal path from the source, which can be caused by camera blur, interlaced scanning, MPEG compression artifacts, poor video processing, insufficient bandwidth, or insufficient CPU speed in the case of games. Further confusing matters, artifacts can occur for different reasons with CRT, LCD, LCoS, plasma, and DLP technologies. It can even occur with OLEDs, if switching speeds aren’t sufficiently high. But when people discuss motion artifacts, they are generally talking about LCD response time. And not surprisingly, the manufacturers’ published specs for response time have become one of the major deciding issues for many consumers. A...

Terjerat KejahatanSendiri Bacaan hari ini: Ester 7:1-10 Ayat mas hari ini: Amsal 5:22, BIS Bacaan Alkitab Setahun: 1 Tawarikh 28-29; Yohanes 9:24-41 Kompas, 16 Januari 2010, memuat berita tentang pemalsu uang yang tertangkap di Kuala Lumpur. Pria ini tertangkap setelah memberi tip selembar uang 500 dolar AS (senilai 4,6 juta) pada pelayan hotel. Pelayan hotel yang merasa beruntung segera menukarkan uang itu. Akhirnya, si penukar uang segera memanggil polisi untuk menangkap sang pemberi tip. Sebab, pecahan tertinggi dolar AS adalah 100, bukan 500! Dari pria itu, polisi menemukan uang palsu senilai 66 juta dolar! “Dosa orang jahat bagaikan perangkap yang menjerat orang itu sendiri,” demikian peringatan Amsal 5:22, dalam versi Bahasa Indonesia Sehari-hari (BIS). Tak selamanya korban kejahatan adalah orang lain. Ada saat di mana kejahatan menjerat pelakunya sendiri. Mengapa? Karena dalam tindak kejahatan tersimpan benih penghancuran diri pelakunya. Sejenak, pelaku keja...

Reblogged from MaximumPC Posted 05/18/10 at 06:03:33 PM by Dr. Raymond Soneira Both manufacturers and consumers are obsessed with contrast ratios. Because many people choose the model with the highest number, manufacturers have developed new contrast ratio specs to win at this game. It’s a sordid business, but deserves exposure, so let’s jump in. When Contrast Ratio Actually Matters
