HD TV Resolution Comparisions
(High Definition Television)
Your final image size will be 1920 x 1293 pixels. The highest resolution HDTV available today is 1920 x 1080pixels. Naturally, the quality of your final image is going to be greatly dependent on the quality of your original slide. Sometimes people think that their slides are in better shape or sharper than they really are. For our own reputation, we are going to get the images as sharp as possible. The display on your widescreen TV will depend on how you have your TV setup. Our slide show is set up to display in the 4:3 mode. You should be able to set your TV up to display in 4:3 or 16:9.

Progressive Scan and Interlaced Scanning
Computer monitors, like HD TVs use progressive scan. Progressive scan writes one full screen of video from left to right every 1/60 of a second. The entire image is drawn at one time--contrasted to an interlaced image where the even lines are drawn first, and then the odd lines are drawn on a second pass. Since a progressive scanned image is displayed in one pass, the image looks more stable than an interlaced image. When there is fast action on your HD TV, such as when you are watching sports, and you have a 1080p display, it will look better than the same image displayed on a 1080i display. The "p" in 1080p stands for "progressive." The "i" in the 1080i stands for "interlaced." If you can afford a 1080p HD TV, definately get one. If you can't afford the 1080p, the pictures on the 1080i and the 720p are absolutely beautiful when compared to the regular TV that we have been used to for years. Once you get into High Definition TV, the difference between the different displays is sometimes hard to pick out.
1080p: Will display onto a 1080p TV from Blu-ray players and future HD-DVD players and PlayStation 3. 1080p has progressive scan.
