iPhone 4 vs. Galaxy S, part deux: HD video playback (video)
We just couldn't leave this face-off of superscreens alone, and went back for another bite at the cherry. Admittedly, we found out the Galaxy S had a browser-specific brightness setting that we hadn't maxed out before setting off our camera hounds, so we've gone and remedied earlier comparison shots with the gallery below, and just as a bonus, we've now also run a HD video clip on both phones. This was to see how the Hummingbird and A4 SOCs, considered close siblings, handled some taxing video work and also to again compare performance deep down on the pixel level. What we can tell you now is that both handsets chewed through the 1080p HD clip with ease and that both gave results we have no hesitation in describing as sublime. Click past the break for the up close and personal video comparison action. N.B. -- We ran a 1080p clip on both phones' respective YouTube apps over WiFi. Although we're certain from the quality of the video that it was at least 720p, we can't say for sure that it was the full 1080 enchilada.%Gallery-96333%

iPhone 4's retina display claim put under the math microscope
Samsung might have entertained us with some trash talk about the iPhone 4's IPS LCD yesterday, but this stuff is of a rather more somber variety. Raymond Soneira, president of monitor diagnostics firm DisplayMate, has said that Apple's retina display marketing is inaccurate, because he believes a display that truly makes pixels indistinguishable to the human eye would require a density in the vicinity of 477dpi. The iPhone 4 has 326dpi, and by now you might be surmising that Steve Jobs flat out lied when he said that the iPhone 4's pixels are too small for the human retina to discern from 12 inches away. But not so fast, says Phil Plait from Discover, whose résumé includes calibrating a camera on board the Hubble space telescope. He's done the math too and finds that the 477 number applies only to people with perfect vision. For the vast majority of us, Steve's claim stands up to scrutiny; even folks with 20/20 eyesight wouldn't be able to tell where one pixel ends and another begins. So it turns out Apple can do its math, even if its marketing isn't true for every single humanoid on the planet.
iPhone 4 pixel density examined (video)
Sure, you've seen our iPhone 4 hands-on... but have you seen it through a retina display? We put the new device next to our trusty old iPhone 3G to get a feel just how different the screens look with twice the pixel density and shot a little pseudo-macro video. There's a marked difference in the screens, even side-by-side with the EVO 4G, and we found that even from a distance we were able to read bodies of text we'd previously had to squint to discern on our classic iPhones. Hard to capture, it really is something you have to see first-hand... but until you get that chance, live vicariously through us after the break.%Gallery-94640%
LG Display busts out 84-inch 3DTV with 3,840 x 2,160 res, we want the 2D version
Yesterday we brought you Samsung's 19 inches of transparent AMOLED goodness, today LG counters with an 84-inch 3DTV boasting UHD resolution and a claim to being the world's biggest of its kind. To be honest, at that size you really can't get away with old reliable 1080p, so it's comforting to see LG's keeping pixel pitch in mind when designing its headline grabbers. In other news coming out of the SID 2010 show, LG is demonstrating a "liquid lens" TV that'll give you glasses-free 3D, though the details of how that works are a bit scarce, while the company's also pushing its IPS wares in a big way, with a 47-inch HDTV, a 32-inch pro monitor, and a 9.7-inch (sounds familiar) smartbook on show. Also at 9.7 inches, we have color e-paper that's slated for mass production before the end of the year, while that flexible e-paper from January is also making an appearance. A pretty comprehensive bunch of goodies from LG, we'd say. Update: We just noticed a small but freaky 3.98-inch UHD LCD with a world's best 394ppi density. Amazing.
