For an HDTV 42 or 46 inches, what is the difference in 60hz and 120hz?


60 hz bad, lot of pulldowns , motion blur. don't recommend less 120 hz.

brands , best least:
- (top brands) panasonic, samsung, lg, sony.
- (top offbrands) toshiba, phillips, vizio.
- when buy tv, make sure , has input , outputs needed, know there smart tv's.

plasma >=< led > lcd (led same, upgrade lcd).
- best picture quality = plasma.
- best audio quality = plasma.
- best energy consumption , environment friendly = led.
- best reliability = led.
- (newer plasma tv's fixed burn in , use little less energy , little better bright rooms, way plasma tv's designed have no motion blur problems).
- (newer led's use motion interpolation frames frame rate of video fix motion blur, can cause soap opera effect, led's bright rooms).

1920x1080 resolution or higher resolution (1920*1080=2,073,600 pixels).
- 1080 resolution better 720 resolution.
- bigger tv's better 1080 720 (if tv around 32 inches or less go 720, bigger want 1080 tv's on 42 inches).
- farther sit away tv means it's better go 1080 720 (if watch more 6 feet away tv, go 1080).

progressive scan > interlaced scan.
- progressive scanning way of displaying, storing, or transmitting moving images in lines of each frame drawn @ same time.
- interlaced scanning way of displaying, storing, or transmitting moving images in odd lines of frame displayed first lines of frame displayed second.
- example: 1080p > 1080i
- example: 720p > 720i
- example: 1080i > 720p (because more resolution better slower passed videos).
- example: 720p > 1080i (because fast pass videos better off progressive scan).

fps = frames per second (of video).
- frame rate how many individual images displayed in second. think of video fast moving flip book.
- ntsc countries use 30p or 60i fps.
- pal countries use 24p/25p or 50i fps.

hz = refresh rate (of tv).
- example: tv 120hz refresh rate, meaning refreshes entire tv screen 120 times second, tv's use black light scanning.

- many tv's allow viewers have computer program in television digitally analyze concurrent frames , use data create intermediary frames. insertion of these frames called interpolation , cause soap opera effect creating more fake frames (higher fps) in between real frames match refresh rate of tv.
- many tv's allow viewers turn off interpolation , force television repeat same frame number of times match refresh rate of tv or use 3:2 or 2:3 pulldown match refresh rate of tv (a pull down cause jittery screen known judder).

ntsc countries:
- example: display 30 frames per second on tv 120 hz refresh rate, each frame repeated 4 times every 30th of second.

pal countries:
- example: display 24 frames per second on tv 120hz refresh rate, each frame repeated 5 times every 24th of second.

when frame rates of video cannot not divide refresh rate of tv equally above examples, there more math , there 3:2 or 2:3 pull downs.

still new 3d tv's, ill have them , not fan of 3d tv's anyways.
- can slow moving scenes.
- when movies start using higher fps (ex: lotr-hobbit 48 fps), 3d better , less blurry during face pass scenes.

not fan of projectors either.

i've done quite bit of research , find answers vary. refresh rate of 120 better worth paying 20 dollars for? best buy has 46 inch led refresh rate of 60hz 440 dollars, while 120hz 460. worth paying for?

snow in march in sleep found childhood friend @ play in northridge park. cheeks stained fallen tears, bobbed hair sleek , dark. snow slow melt march, our breath condensed in air , recall clarity while on lower stair, neighbour called pass on news, jeannie's mum dead. overheard whispered tones, should have been in bed. oh jeannie after time, face still wet grief. have pleased me more if had found relief. if had captured in eyes laughter once shared, wouldn't feel life had been impaired. snow in march in sleep found childhood friend @ play in northridge park. cheeks stained fallen tears, bobbed hair sleek , dark. snow slow melt march, our breath condensed in air , recall clarity while on lower stair, neighbour called pass on...

Peugeot 106 door stuck open?

agree other contributors door stay/check arm not going in properly. however, having replaced 1 on 106 last tuesday, understand how work. if can contort in door stay goes in door, stay should flat , pass between 2 upright cylindrical rollers. should not able see end of stay, supposed hook behind 1 of rollers inside door itself. if rollers aren't upright, need new door stay assembly (about £25 peugeot). if stay no longer hooked behind rollers, rollers ok, may able put end of stay through. bit fiddly (i had when fitting new 1 car), 1 of rollers spring-loaded , has levered (you can manage shortish flat screwdriver , 3 skinned knuckles!) allow hooked tip of door stay pass through. not recommend "heavy friend" leaning on door, bend stay, or damage door. if end replacing stay assembly, have remove door inner trim panel @ roller bit. can give advice on fitting new 1 if needed, have typist's cramp @ moment(!), post again if need more help. luck. the door opened wide ,...
