How can we know whether the scratch is on screen guard or in the mobile screen without removing screen guard?
Most, if not all screen guards would actually cover / disguise a crack / scratch on the screen when properly placed. So if you see a crack or a scratch on the screen of a screen guarded phone, it is more likely that it's on the screen guard, unless, if you can actually see the scratch / crack exceeding the outline of the screen guard.So I believe the best method would be to carefully check using your eyes. Other methods like applying some toothpaste on the screen can also be used to be sure however, the very first step is to carefully examine the screen to see if the line of the scratch / crack actually exceeds the outline of the screen guard.
Why don't movies in DVD format fill the entire screen on my new TV?
3 possibilities -1) Aspect ratio on television set incorrectly (as mentioned above) Use your TV remote to change - it varies by TV, but typically there's a 16:9 vs. 4:3 setting (which you'd want set to16:9, then there are various 'zoom' settings that can change the appearance. if your issue is that you have black or white space to left or right of pic, then this is likely your problem.2) Aspect ratio on your cable box/dish box, etc. Same as above; often will combine with TV settings making it even more difficult to figure out. Set TV to 16:9 and Zoom to 'Full' or 'Wide', then adjust cable set-top box.(cable box settings (#2 above) will only affect DVD playback if DVD output runs through cable box)3) MOST LIKELY - DVD's can be recorded at various aspect ratios (length to height). Believe it or not, a lot of movies shown in theaters use a 2.35:1 ratio. If this is transferred to DVD, you will have black or grey bars above and below your screen, b/c a typical HDTV uses 16:9, or 1.77 ratio. Look on the box cover of the DVD. If it states '1.85:1' or just 1.85, then you should be good. If it states 2.35, expect the black bars. If you absolutely hate them, you can 'zoom' in with your TV control, but you'll lose some of the left-side and right side.

How does one calculate a television's height and width based on its diagonal length and aspect ratio?
Let a, b, and c be the height, width, and the diagonal of the screen respectivelySince they form a triangle and the angle between a and b is 90 degrees, according to the Pythagorean Theorem a^2 + b^2 = c^2Let's assume that the aspect ratio is 16:9. Therefore b/a = 16/9Now we have a system of two equations with two unknowns. We need to express everything in terms of a single unknown, so let's express a in terms of b. Since, b/a = 16/9, by cross multiplying 16a = 9b. Therefore a=9b/16. Now we can subsitute 9b/16 for a in the first equationa^2+b^2=c^2 becomes (9b/16)^2 + b^2 = c^2 Squaring the nominator and the denominator of the fraction yields81b^2/256 + b^2 = c^2 To perform the addition, we need to express b^2 as a fraction with denominator 256 which is 256b^2/256, Now we have81b^2/256 + 256b^2/256 = c^2 Adding fractions with the same denominators is now easy and produces337b^2/256 = c^2 Cross multiply to get 337b^2 = 256c^2Divide both sides by 337 to get b^2b^2=256c^2/337Take the square root of both sides to get bb = sqrt(256c^2/337)Now, let's assume the TV has a diagonal of 55 inches, then b = sqrt((256 * 55^2)/337) = sqrt(774400/337) = 47.936654541850210631076300226891Now that we know b, a = 9b/16 = 26.964368179790743479980418877626
