actually HD ready means can accept HD signal like 1080i and 720p..
doesn't mean it outputs HD resolution. cos 1024x768 ain't HD resolution. it could be even 854x480 HD ready, which is EDTV (enhanced definition TV) which is rare these days.. cheers! This post has been edited by ar188: Dec 20 2008, 09:11 AM |

QUOTE(slk5538 @ Dec 22 2008, 09:07 AM) Read in Wikipedia and others websites like cnet that defines HDTV. yes, HDTV must be able to display at least 1280x720pBesides able to accept HD sources like you mentioned, these website also stated that HDTV must be able to display the images at 720 lines in progressive scan mode or 1080 lines in the interlace mode. So, 854 x 480 TV can't possibly display images at 720 lines. I agree with you that EDTV can accept HD signals, but it is termed EDTV, and not HDTV. EDTV are actually those TV with standard resolution but design to received HD sources during the ninties, when 720p panels were still very expensive. The link belows provide classification of HDTV http://www.cnet.com/hdtv-resolution/?tag=rb_content%3brb_mtx Also, ideally the pixel resolution for a HD Ready panel should be 1280 x 720, but 1024 x 768 is acceptable for Plasma TV due to it's cells that are not round, and can't get 16:9 ratio if manufactured to 1280 x 720. You might have read somewhere that says otherwise, mind to share? As at one time, I encountered a FULL HD TV claimed by a manufacturer for its 720p panel capable of receiving 1080p signals at 24 Hz. I personally think that this is cheating. I know this is quite confusing, and I think by better understanding the terms and definition, then we won't be easily cheated by the manufacturers. So, If you had read in somewhere that says otherwise, please share. Thanks if not then it's just HD ready TV.. so that's why those with 1024x768 HD panels can't be called HDTV but rather "HD" TV.. i..e more Hidef than sd TV but not really "HDTV" anyway, no need to be too concern about terminology.. just know HD ready means able to accept HDTV signals (but doesn't mean it's a true HDTV output) while HDTV means able to display minimum 720p, and check for your self the actual panel pixel spec rather than those stickers that say HDTV or HDready.. while plasma can't get 1280x720 (not that I notice before) it comes in resolution of 1366x768p (16:9) and 1920x1080p so the argument it's cells are not round hence can't do 1280x720 is outdated in current year 2008 (maybe in 2004/05 is valid la.) |

QUOTE(tepetlah @ Dec 23 2008, 09:40 AM) if want fullHD Minimum is 40" so that u can see the different of 720p n 1080p..anyway why sony s series 40" only stated fullhd 1080 instead of 1080p..1080 can be 1080i n 1080p..if 1080i better 720p i think yeah somehow, if need full HD need to be larger, however LCD monitors like those 24" sizes have higher resolution lien 1920x1200 cos we sit very near.. so maybe those 32" are suitable for those playing PS3 via 1080p and sitting much closer than normal.I also think 1080i is better except for fast moving scenes like sports etc.. |

QUOTE(kepco @ Dec 24 2008, 08:46 PM) watching 720p material in 1080p panel will have black bar on top and bottom, watching DVD (window) will become smaller. If someone stretch or pan, end up, people body ratio look very funny. Sorry bro. 720p and 1080i/p is same widescreen ratio 16.9. So when viewing 720p material on 1080p tv no black bars anywhere. Cheers.I find most of the people don't mind this stretch or panning, but I always find it funny when the actor/actress have small head with big shoulder. (almost every one become Micheal Phelp). |

QUOTE(Matrix @ Dec 25 2008, 08:59 AM) Err..that is also not quite correct. The black bars are caused by aspect ratio(like 2:35:1, 1:85:3 etc etc), not whether it'ss 720p or 1080p or what resolution. you not quite right either..I was responding to his original statement,Merry christmas!!! "watching 720p material in 1080p panel" 720p material is 1280x720 pixels. we don't care it got black bars or not, just the entire video of 720p. yours is a specific statement regarding 2.35:1 encoded to 720p (hence black bars are a part of the 720p video) while what I said covers both 16:9 (no black bars) or 2.35:1 (inclusive o black bars) encoded to 720p video. besides there is no such thing as a 720p/1080p video 2.35:1 ratio and no black bars... 720p and 1080p are 16:9 ratios.. if you watch 2.35:1 on thse standard HDTV formats, black bars are a part of the video. cheers...and hohoho merry christmas to you too...

QUOTE(piscesguy @ Dec 27 2008, 09:53 AM) I thought "HD Ready" refers to any display that is capable of accepting and displaying a high-definition signal at either 720p, 1080i using a component video or HDMI.. dun char him la.. Added on December 27, 2008, 10:09 am QUOTE(iamsobloodysick @ Dec 27 2008, 10:00 AM) anything not FULL HD is actually SD? downgraded 2 levels from the FULL HD standard?!?!? lol... kenot kenot.. LCD 1366x768 is not really 720 or 1080p either.. so dun have 1:1 pixel mapping so it's actually worst than 480P SD i guess he is applying the theory of HD ready from LCD panel into plasma HD panel. LCD TV =1366 x 768 (real HD ready) vs PLASMA TV 1024 x 768 (fake HD ready). This post has been edited by ar188: Dec 27 2008, 10:09 AM |

QUOTE(gogo2 @ Dec 27 2008, 11:00 AM) ok la... i'm just talking nonsense here.... I still do care but nowadays if your source 1080p blu-rays exceed your Display resolution i,.e. less than 1080p TV panel or projector.... then not much to worry about anymore..Let's come to real issue. Why no one care about 1:1 mapping, Half HD (720p) and FullHD (1080p) anymore? I didn't come to this forum for so long and seems everybody don't care oredi. I just feel weird. |

this confirms the fact that normal/cheapo lcds with ccfl backlight are lacking in pq.. Vibrant lcd colors doesnt mean good pq. Dunno how many proponents of lcd actually have led backlight lcd tv?
Added on December 28, 2008, 1:54 pmas for blooming fm led backlights becos insufficient led cluster points due to cost and signal processing. Usually only got 128 points. The top end ones use over 1k points. Dunno how much though. This post has been edited by ar188: Dec 28 2008, 01:54 PM |

Yeah, nothing wrong if DVD and Astro. Ahem Blu-Ray disc is RM60 only. Actually, I'm just saying kena conned by people who tell them to buy 42" non-HD plasma. Actually, why not buy 50" plasma. The 50" PV80 is 1366x768. If wanna buy PV80, just buy the 50" one la.... But there's really big difference between 720p and non-720p. Go check out yourselves. PV80 50inch how much ar? |

1080i60 with proper pulldown flags inserted can recreate 1080p24 (in slow or still video scenes)
for fast moving scenes, there will be missing information.. of cos advanced motion adaptive algorithms in powerful deinterlacers (better than those built into LCD/plasma HD TVs) can be used to close the gap to rebuild 1080p24 but never 100% due to time differences between interlaced frames |

barricade has brought up some interesting points about 1024x768 HD and 1440x1080i digital video cams being fullHD even hitachi's ALis 1080p which is like 1280x1080... or something like that.. lots of marketing mumbo jumbo,
gogo2 shouldn't be too anal about it... I know you want to follow ATSC's definition rather than CEA (more consumer type marketing) but no need to harp about it too much lor.. marketing people mah.. surely more "creative" in inventing their own specs...
