Zee530 Wrote:basically what makes a display 1080p The number is the height in pixels and the letter is the format. 1080p is 1080 pixels high in progressive format. 480i is 480 pixels high in interlaced format (now in SD territory). The aspect ratio is not given, but it's easy to guess with 1080p: it's almost always in 16:9 ratio so 1920x1080. Things get kind of fuzzy at smaller stuff though. 720p can either be 1280x720 or 1366x720 depending on the pixel width (NTSC pixels are wider than they are tall). Same goes for 480i 16:9 with NTSC widescreen (720x480) versus 480p 16:9 with square pixels (853x480). Then there is different aspect ratios, such as 480p meaning 640x480. It's a tad... nuts.

What does a cracked or broken solder joint look like? Got a soldering iron and solder, going to attempt repairs on my motherboard. Need some pointers on soldering, do I repair the circuit with new solder or melt the existing solder to seal the connection?

These look duller (i.e. less shiny) than they should. Sometimes they'll work for a while, due to the fact that there're still metal touching metal, so conduct, but then something slips, and due to the fact that the joint is only touching, not 'welded' together, the connection is lost. You fix this by either melting the old solder to make a new joint, or replacing it with new solder. You may find that the first option doesn't work because the old solder is 'dirty', which is when you'll need to do the second. Basically, if something is less shiny than it's friends, it's likely the problem.

Both are 16:9 AR. 1280x 720 is the more proper of the two since it is actually 720 lines of height. The main reason 1366 x 768 became the standard for HDTV hardware and later computer monitors is because of the widespread and cheap XGA display controllers and panels at the time (1024 x 768). Which of course are wired for 768 "scanlines" instead of 720. Since you can't really tell the difference between 720p content on a 1280 x 720 display vs. a 1366 x 768 display hardware manufacturers were too lazy to move to 1280 x 720. So it became the standard. It also has the added benefit of providing a bit more resolution for 1080i and 1080p content. And since it's a higher resolution than 1280 x 720 and was already the standard for HDTVs it was logical for PC monitor manufacturers to adopt it as well. Oh and NTSC uses square pixels (or more correctly it doesn't even have pixels since it's an analog standard). ATSC CAN have non-square pixels. And usually that's the case. However with HD resolutions ATSC always uses square pixels. On 1366 x 768 displays 1280 x 720 content is simply scaled by a factor of 1.066 along both axis. The AR/pixel width is not changed at all.

Are you sure it's 1360? I mean they do exist but like I said they're rare. Sometimes the EDID doesn't report it properly. I've had that happen to me before.

If the EDID isn't reporting it properly how else could I tell? It's a tv and the weird thing is I traded my tv for my brothers tv the day I moved for college and his and my old one are both 1360x768 so I supposed the EDID could be reporting wrong but I would have no idea how to check.
