Mini Itx Htpc Build 1080p Projectors UPDATED
The motherboard happens to have a mini-PCIe/mSATA slot on it, giving my old Intel SSD 310 mSATA drive a purpose in life. Small SSDs make for great HTPC boot drives (silent, cool running, low chance of failure right before you want to watch a movie). The mSATA interface also removes the need for running SATA and power cables, a welcome benefit when building a cramped mini-ITX system.

1080p playback on the first-generation Apple TV (a.k.a. "ATV1") can only be achieved by hardware accelerated video decoding via Broadcom Crystal HD; the user must replace the ATV's internal WiFi adapter with a Broadcom Crystal HD PCI Express Mini (mini-PCIe) card in order to activate this functionality.[24]
Some examples on building on Kodi-XBMC are LibreELEC, OSMC, OpenELEC and GeeXboX which are free and open source embedded operating systems providing complete media center software suite that comes with a preconfigured version of Kodi/XBMC and DVR/PVR plugins. They are both designed to be extremely small and very fast booting embedded Linux-based distributions, primarily optimized to be booted from flash memory or a solid-state drive, and specifically targeted to a minimum set-top box hardware setup based on ARM SoC's or Intel x86 processor and graphics.[54][55][56][57]
Two years ago, Optoma brought the price of 1080p projection under $1000 for the first time ever with the HD20. As it turns out, the HD20 is still one of the finest 1080p projectors under $1000, despite two years' worth of competition. Now, Optoma has released the HD33, a DLP 3D 1080p projector that sells for less than $1500. This is the first 1080p 3D projector to break the $3000 mark, let alone the $1500 mark, and that in itself is worth getting excited about. Add to that the HD33's solid 2D performance, great color, radio-frequency glasses, and virtual absence of crosstalk and you've got a projector that is a solid value at twice the price. At $1500, the HD33 is a steal.Editor's Note 8/26/11: The original version of this article stated that the projector came with one pair of glasses. The glasses are actually purchased separately. We apologize for the error.The Viewing ExperienceWhile technical details can reveal a lot, the most important consideration for any home theater projector is how it looks--and the HD33, in a word, looks good. The default mode, Cinema, is also the best mode for movies and video, and we measured this mode at 847 lumens with the lamp at full power. This is a lot of light, so the first thing we did was switch to low power, called Standard on this projector. This brought light output to a more manageable 661 lumens, which is still plenty of light. We settled on a screen size of 120" diagonal--you can go bigger with a higher-gain screen or excellent light control--and fired up the Blu-ray player.The Optoma HD33Contrast on the HD33 is only 4000:1 full on/off, and it shows at times. The projector has no iris, auto or otherwise, and black level can suffer because of it. There is the ImageAI function, which varies lamp power in response to the content on screen, but this also causes fan noise to fluctuate and in our experience is not as fast as a good auto iris. Black level on the HD33 is very similar to black level on the older HD20, which we put up head-to-head with this new model. On the other hand, dynamic range shows a clear improvement, and the HD33 looks much more three-dimensional than the older model. The HD33's picture at times looks poised to pop off the screen. The image is vibrant, color is saturated without being overdone, and fine detail is razor sharp. It is a beautiful picture. Next up is 3D. The HD33 is a full 1080p 3D projector with full HDMI 1.4 compatibility. It uses radio-frequency (RF) glasses, meaning line-of-sight is no longer required, as is the case with infrared (IR) emitters. Our preferred test disc these days is The Ultimate Wave: Tahiti, an IMAX film shot in 3D using live actors instead of CGI. The picture was plenty bright for our setup, perhaps even a touch too bright. A touch of ambient light in the room should not do the image much harm. The HD33 strikes a good balance between light transmission and crosstalk, which we saw very little of. The glasses never lost sync thanks to the RF transmitter--turn your head away or look down at the remote and the glasses keep on going. In the past, we have seen IR glasses lose sync at the slightest provocation. Color in 3D is about as accurate as we've seen, though the glasses do add a slight tint of green to the image. Since the HD33 has a separate 3D preset, this can be calibrated out if desired. All in all, it was one of the more enjoyable 3D experiences we've had in the home, regardless of price.
The Optoma HD33 is a projector of firsts. It is Optoma's first 1080p 3D projector. Previously, the company has made a number of 720p DLP Link 3D projectors meant to be used with PCs, but this is their first foray into HDMI 1.4 compatible 3D. It is also the first 1080p 3D projector under $3000. Other 1080p 3D projectors start at $3499 and go up from there. Finally, it is the first 3D projector to our knowledge to use RF glasses technology, eliminating concerns about line of sight and screen bounce.The HD33 shares a lot in common with the older HD20. Both significantly altered the market upon release. Before the HD20, no one had ever seen 1080p under $1000. Before the HD33, no one had ever seen 3D 1080p under $3000. Beyond that, though, the two projectors share the same smooth, natural picture that videophiles enjoy so much. Perhaps most importantly, both projectors offer performance disproportionate with the price. When you are looking for a high-quality 3D projector and want the absolute best value for your money, the HD33 is exactly what you've been looking for.While we have assigned star ratings to the HD33, these are preliminary and based on our opinion of the projector at this time. As competing models come out, we may revise these ratings to better reflect the projector's position in the current market. However, we suspect the HD33 will remain a strong contender in this year's home theater projector lineup. Its combination of performance and low price is simply too attractive to be ignored.

Almost all projectors that offer a 4K image or its equivalent at prices below about $4,000 use one of two pixel-shifting techniques. The majority are based on 1080p DLP chips that use TI's XPR fast-switch pixel shifting. This technology breaks each 4K frame into four sets of 1,920 by 1,080 pixels, then displays all four sets on screen one at a time, shifting the pixels' position between each set. Your eye integrates all four sets into a single 4K image.
At this writing, the only projectors in this price range that use a different pixel-shifting technology are Epson's 4K Pro-UHD models. The Epson scheme uses three 1080p LCD chips and puts two sets of 1,920 by 1,080 pixels onscreen per frame.
As you may already know, the improved image quality of 4K flat-screen TVs over 1080p models depends not only on quadrupled resolution but on the shift from standard dynamic range (SDR) to high dynamic range (HDR), which was introduced along with 4K. Unfortunately, current projectors simply can't produce the peak brightness required by HDR, unless you make the image so small that you lose the inherent projector advantage of delivering a much larger image than any similarly priced TV or other display. Many have trouble delivering suitably dark blacks, as well. As a result, although many 4K projectors do offer HDR support, some don't support it at all, and some of those that do don't handle it well.
An upcoming format which should quickly become widespread is HDR10+. This builds on HDR10, both improving image quality and eliminating some of the manual adjustment HDR10 requires when switching from one image source to another. A fourth format, Dolby Vision, is common in TVs but exceedingly rare in projectors, and likely to stay that way due to technical issues.
At this writing, there are no palmtop or pico projectors with 4K resolution, and none that works on battery power. The most portable 4K model is at the high end of the mini projector range, but only if you stretch the definition of "mini" to just under 4 pounds.
The main advantage of LCD technology is the same for 4K as for 1080p: It can't produce rainbow artifacts. These flashes of red, green, and blue come from using a single chip for all three primary colors and rotating through the colors in sequence. LCD projectors (except for a few lower-resolution portables) use three chips rather than one, which lets them project all three primary colors on the screen at once.
The input lag of any given projector will vary with its resolution and refresh rate. (The latter is the measure of how often the screen image is redrawn.) Doubling the refresh rate will generally cut the lag in half. However, a projector capable of a 240Hz refresh rate at 1080p resolution will likely be limited to 60Hz at 4K, thus an input lag that's four times as long. For current gaming projectors with the shortest available input lag, that translates to roughly 4ms at 1080p/240Hz and 16ms at 4K/60Hz.
The conventional wisdom in the projector business has long been that people who need high-quality or high-volume audio are going to use external soundbars or speakers, so there's little point in trying to build a deluxe sound system into the projector itself. For that reason, home theater projectors traditionally don't have any onboard audio. 350c69d7ab
