The main TV purchases.1. the number of pixels.Current technology is subject to rapid development, it. Tv we buy little example should have a resolution of up to Full HD level, little 1080p, but if there are many who are buying one, consider a higher resolution is Ultra HD or hit that 4K (3840x2160), not that many people might think that high-definition tv is also no longer necessary because the content is also not widespread. But we want to say it again that in the current system, up scale images of TV so far and then developing to UHD. 2.Contrast Ratio The higher this value, the better Contrast Ratio value because this is the ratio of black that black and white-white tv can display. Any tv with an ultra-high contrast ratio will show images, see deep hierarchies are unrealistic. You will keep the details of your pictures in dark scenes (black, not grey) colours, the brightness of the image is good, the images will have dimension. Details are vague, if not valuable, High-Contrast tv it will have a more realistic.3. Response TimeThe lower this value, the more I go overboard, at least should be low that Response Time 4ms value this is the response speed of the display when changing from pixels, black and white, then change from white to black again by the millisecond. (Ms), however the user than is often seen bundle specs that reference numbers somewhat. The cause is because the manufacturer, each brand has a Response Time of the measurement methods themselves, so buyer should test this with your own eyes rather than believe the specification is written, bundle. 4. have a comprehensive.-If a size 42 "and up should have an HDMI version 1.4 (but if buying a tv should be TV HDMI UHD version 2.0) with the 3 little! but if it is smaller than most of the individual brands are supplied for 1-2 channels only.-Jack Component should have at least one series.-Optical Jack-USB Port connection section in the current version of the fictional size 32 "least, 1 channel, then the middle size 40" up to should be at least 2 channels. 5. stand and view.I have to admit that the stand of most current tv nearly 80% left-right cannot be rotated. Before buying, be sure users, taking into account that the time we actually use. To much tv, however, the production technology and development is very simple. The user can choose to buy larger TVs in less. So the problem with the rotation of the stand so you hardly need attention. The user should consider the views of tv instead. Honorably before buying the user should try to see a side view of the tv, the picture is, however, is different, however, from looking in the Middle much with. 6. DesignIf the tv does not even say what it is not different with the wrong because the first tv is often placed on the living room. So choose the design of the tv to match the furniture, it is considered one of the arts. Therefore, each brand, in addition to input the subject image and still think regardless of the design, the user likes. Design matters, it depends on the individual, because each preference are not the same.7. the size of the monitor (a very important factor).เชื่อว่าหลายๆคนที่เคยซื้อ LCD TV หรือ Plasma TV ไปแล้ว ใช้ไปซักพักจะเจอปัญหา "จอหด" คือทีวีที่มีอยู่ที่บ้านมันดูเล็กเหลือเกินทั้งๆที่ตอนซื้อเราก็ว่าใหญ่แล้วนะ ทางผู้เขียนแนะนำให้ซื้อขนาดที่ใหญ่ และเป็นขนาดที่ "ใหญ่แบบพอเหมาะ" มิใช่ใหญ่จนเกินไปจนสายตากวาดไม่ทั่วประหนึ่งนั่งแถวหน้าสุดในโรงหนัง หากมีระยะดูซัก 1.5-2.0 เมตรขึ้นไปก็แนะนำระดับ 40" ขึ้นไป หรือหากมีระยะรับชมซัก 3.0 เมตรก็แนะนำขนาด 50" ขึ้นไป ขนาดยิ่งใหญ่ = เป็นการขยายขอบเขตความสุขในการรับชมให้มากยิ่งขึ้น และเป็นการซื้อทีเดียวจบด้วยครับ
