Home Theater: How to Choose The Best Projector
December 26, 2019
The central and most important central equipment for a home theater is a projector. Unlike office projectors, home projectors usually have a wide aspect ratio of 16: 9 and are designed specifically for movie projection.
When deciding on a projector, you should not rely too much on the specifications given by the manufacturer as they tend to be overblown to reality. It’s best to look for information about the machine through the reviews of experts, or from the tech community, and then watch the demo of the machine directly at the shop selling projectors.
Usually, we can easily distinguish home projectors from office projectors. Office projectors often have a high brightness of over 3,000 lumens due to being used in a bright office environment. However, the contrast of the device is quite low, below 3000: 1. Whereas the projectors have lower brightness because they are used mainly in dark rooms, but give very realistic colors and tens of thousands of contrast.
With the development of technology, the quality of home cinema projectors has been constantly improved, and besides, the price has been pushed down to an unprecedented affordable level.
With an investment under $ 1300, you can consider already popular models such as Optoma HD25LV, BenQ W1070 or ViewSonic 7820HD. These projectors all have Full-HD resolution and are equipped with 3D projection feature.
With a higher investment of $ 2100, you can consider high-end models such as Epson TW8100, Optoma HD8300, BenQ W7000 or Panasonic PT AE8000. Of course at this price, the quality can satisfy even the most demanding audience.
A major concern of projector users is the lifetime of the projector lamp. This issue is currently being addressed by projector vendors. And the lamp life has been increased to over 5,000 projection hours. This means you can enjoy thousands of movies without having to consider replacing the light bulbs. The price of genuine light bulbs currently ranges from 200 to 300 USD depending on the company.
As for the camera body, carriers usually offer a 2-year warranty, especially up to 3 years. In order to be assured of using the device, the advice given to users is to choose reputable suppliers and have a good after-sales warranty to buy the machine.
Best TV models for football fans to watch the match
December 14, 2019
For sports people, enjoying the game on the big screen always gives the most feeling. However, not all of us can choose the right TV that suits the needs. Below is a list of the most valuable samples, reference from the US audiovisual product evaluation forum.
This is a high-end product of Samsung using LCD panel combined with quantum dot technology. For sports and football, the most important factor is the ability to handle movement and the Q8 is a good model to do this. Technology site LCD TV Buying Guide rates this product as “good for sports and gaming needs”, while TechRadar adds that “high brightness, colors that evoke emotions, and sharpness.” The TV is capable of promoting images to a higher quality. “
However, both technology sites should note that you should turn off the settings related to motion processing. Help bring a better experience. Damar1979 member from AVSforum also rated QLED Q8, he praised this is a rare LCD TV model with impressive contrast very close to the OLED TV. The same compliment for vibrant colors, wide viewing angles.
In Vietnam market, QLED Q8 has two sizes of 55 and 65 inches, the current reference prices are 52 and 80 million, respectively.
2. LG B8
An LG OLED model appeared also not surprising. Rtings website reviews B8 with extremely wide viewing angle, with instant response time are the two biggest plus points. While the LCD TV Buying Guide praises the deep black, the image quality characteristics are excellent. CNET has the same judgment on factors such as homogeneity, deep black, contrast, viewing angle, …
However, the US technology site noted to readers that, when dealing with movement B8 movement, the black frame inserting algorithm (BFI) may not be very good. The minus point you have to trade is that the brightness can be reduced, the image is less sharp. CNET noted that you can turn it off if you are not satisfied.
3. Sony Bravia X90F
And finally in the current list of AVSforum, also the brightest option, the X90F model of the Japanese representative. The point of AVSforum is that watching sports means non-stop movement, with very fast speed. So a poor motion-handling TV means it can’t keep up with the frame of the game, your experience will be greatly reduced.
Sony’s X90F is simply the best model to do this. Thanks to a new technology called X-Motion Clarity, it helps the TV divide the frame into sections and insert the black frame exactly into those parts, keeping up with the overall picture that is moving very fast. Besides, it also maintains a stable backlight brightness, thanks to the full-array LED backlight system and proprietary control algorithm. TechRadar commented on the effectiveness of X-Motion Clarity as “undeniably making motion more natural and sharper”.
If you just want the best match for football matches, AVSforum’s advice is the X90F. Sony TV’s ability to handle motion limiting blurring, soap opera effect, and motion interpolation, etc., is often very good thanks to its proprietary image processing chipset. However, it was not until the X90F with X-Motio Clarity that the experts were convinced.
