So what is an HDTV? On Wikipedia, it says this: "High-definition television (HDTV) is video that has resolution substantially higher than that of traditional television systems (standard-definition television). HDTV has one or two million pixels per frame, roughly five times that of SD (1280 x 720 = 921,600 for 720p, or 1920 x 1080 = 2,073,600 for 1080p)." Now if you ask me, that is a mouthful. What the heck does all that mean? Simply put, the quality of the picture in the HDTV is much better than in a regular TV. The colors and picture quality are much better. If you walk into an electronics store and ask them to show you a side by side comparison of a standard TV and an HDTV with a TV show or a movie from the same DVD or Blue Ray disc, you will be able to see the difference such as the quality of the picture showing up on the screen, the image on the screen doesn't look pixelated (distorted). Now let's try to explain what those numbers that look like math problems mean.
The numbers are what is known as Frame Size and these are measured in pixels (single points that when put together make up a picture/image). On a TV this means the horizontal and the vertical size of the picture is what constitutes the frame size. If you ever wondered what a 720 or 1080 number was on the label of one of these TVs, this implies the vertical size of the picture. So the higher the number, the better the picture whereas the lower the number, the more the picture will look distorted on your TV. Of course, the better the number, the more money you will need to dish out but we will get to that later.
I took from Wikipedia a table that shows the High-definition display resolutions:
| Video format supported [image resolution] | Native resolution [inherent resolution] (W×H) | Pixels | Aspect ratio (W:H) | Description | ||
|---|---|---|---|---|---|---|
| Actual | Advertised (Mpixel) | Image | Pixel | |||
| 720p 1280×720 | 1024×768 XGA | 786,432 | 0.8 | 4:3 | 4:3 | Typically a PC resolution (XGA); also a native resolution on many entry-level plasma displays with non-square pixels. |
| 1280×720 | 921,600 | 0.9 | 16:9 | 1:1 | Standard HDTV resolution and a typical PC resolution (WXGA), frequently used by high-end video projectors; also used for 750-line video, as defined in SMPTE 296M, ATSC A/53, ITU-R BT.1543. | |
| 1366×768 WXGA | 1,049,088 | 1.0 | 683:384 (approx. 16:9) | 1:1 | A typical PC resolution (WXGA); also used by many HD ready TV displays based on LCD technology. | |
| 1080p/1080i 1920×1080 | 1920×1080 | 2,073,600 | 2.1 | 16:9 | 1:1 | Standard HDTV resolution, used by Full HD and HD ready 1080p TV displays such as high-end LCD, Plasma and rear projection TVs, and a typical PC resolution (lower than WUXGA); also used for 1125-line video, as defined in SMPTE 274M, ATSC A/53, ITU-R BT.709; |
The table above just shows what HDTV is best for what situation. Unless you have the money and wish to splurge on yourself, I wouldn't go and get the one in the last entry of the table. I would see that more in a sports bar where it would be beneficial. Most cable/dish companies now offer HD channels free with your package if you have an HDTV (I recommend getting it). So now let's talk about the 3DTVs.
Pretty self explanatory, a 3d TV projects a television image in 3 dimensions (3D). What is good about TVs like this is not only can it projects shows/movies in 3D, but any other shows that are still in the 2D format as well. They have the same concept of the resolution as a high definition tv, only in 3D format. One major difference is should you wish you watch anything in 3D (like a 3D Movie on Blue-Ray/DVD or a 3D channel on cable TV) you require special glasses. Some of these 3D TVs have glasses that require to be charged, and some others do not. Think of going to the movie theaters to watch a 3D movie, they provide you with glasses, so its the same concept as that, without the noise of the other people in the audience.
So what do I suggest to get? Let me start by saying I have checked out both. I personally own an HDTV from Sony and I have tested in the stores a 3DTV with the glasses. The best test to do with this is with one of my favorite movies "Tron Legacy" (if you haven't been able to tell how much of a geek I am, that should prove it LOL). I watched both movies and I will be honest. The 3DTV and the HDTV looked very crisp and just amazing, not to mention the sound. However, I have such a hard time having to deal with the glasses. I find it that after awhile, the glasses get a bit tight. Now I am know to take very good care of my electronic but I don't live by myself. I have a dog at home and he loves to jump around and grab things. My wife and I may also forget to move the glasses to a safe place so if we sit down and hear a crunch, there goes the glasses. If we have children over, and they grab hold of the glasses and pull them or scratch the lenses, then you are done for it. You will need to fork out a lot of money to replace the glasses. Most 3Dtvs come with 1 or 2 glasses (depending on the type of deal they may have). Lets say you broke 2 glasses, retail value to purchase just one can run you about 100 dollars. So you are essentially paying 200 dollars for your pair of glasses. I don't know about you but I don't have that kind of money.
Again, if you have the money, then go for it but to be honest, I wouldn't waste my money on that. I have the best quality with my HDTV at home and I get more satisfaction of going to the movies once in a blue moon to watch a movie in 3D there. Until the companies are able to design the 3DTVs in a way where you wont need glasses, I'd say hold off on spending money on the 3DTVs.
That's all for now. Be safe and happy.
surprisingly beneficial material, all round I picture this is worthy of a book mark, thanks
ReplyDeleteVery quickly this web page will be famous amid all blogging viewers, due to it's good articles or reviews
ReplyDeleteI do consider all the ideas you have offered in your post.
ReplyDeleteThey're really convincing and will definitely work. Nonetheless, the posts are very brief for starters. May you please extend them a little from subsequent time? Thank you for the post.
First off I would like to say great blog! I had a quick
ReplyDeletequestion which I'd like to ask if you don't mind. I
was curious to know how you center yourself and clear your head prior to writing.
I have had difficulty clearing my thoughts in getting
my thoughts out there. I do enjoy writing but it just seems like the first 10 to 15 minutes are usually wasted simply just trying to figure out how to
begin. Any recommendations or tips? Appreciate
it!
Thank you for your response and for taking the time to read. Honestly it isn't easy ... i first do my research online and read. I tend to scribble things down as well but now with my tablet, its easier to just type my thoughts on there. I also do bits at a time, I try not to sit there and do it all in one shot. I tried it before and it discouraged me. Its ok to have several drafts of what you want to say ... once you have it down, before publishing it, ask a friend or loved one to look it over. Then publish it. I hope this helps. Thanks for reading!
