So I’ve had my Mac Pro hooked up to my Sharp LC-47SB57UT 47” LCD and have loved it since the first volts of current passed through its wires to turn both it and me on. But there was always something that bothered me, the black border around the desktop that isn’t quite filling up the entire screen!

Sure I’ve overlooked it this far, but I think its come time to tackle this problem once and for all. I’ve tried a couple different applications out there for the Mac OSX that helps resolve issues of scaling the resolution correctly to fit your flatscreen pixel to pixel, but have found that SwitchResX is the best out of them all, considering it has a lot of fluid options to control both the entire desktop when loading at startup as well as individual applications when launched.

For many of you that have experienced this problem with your Mac’s, you know that it can be a very aggravating experience to fix the timing and resolution settings to be in perfect sync for your monitor to recognize correctly. I had a Powerbook G4 that was quite often hooked up to my Sharp Aquos model LCD that with a few hours of tinkering with SwitchResX, was able to get it going — with the help of Sharps menu within the its control panel to “fit” and “scale” the picture to be either “dot by dot” or “letterbox”, etc. etc.

With the Sharp (non-Aquos) LC-47SB57UT model I have, it lacks that same menu to choose a “dot by dot” setting which makes things much more difficult because usually, that along with checking “Overscan” within the System Preferences > Display > Options pane does the trick. Not so this time around!

So in I dove with SwitchResX and reading all the tutorials, posts, and blogs out there about others frustrations with getting their custom resolution settings correct. Im just going to come out and say it, I need help! To those who know their way around SwitchResX and timing definitions I would be most appreciative if you could send a little help my way. The following is my EDID info for my Sharp LC-47SB57UT I have:

My Display Settings when going to System Preferences are as follows:

And finally, when I open SwitchResX and add a Custom Resolution setting, the defaulted settings that are currently in use are pre-loaded as seen below:

But after days, and now weeks of trying to tinker with the right timing settings and (probably) doing incorrect math to make sure I don’t blank out my monitor, I cant avoid the fact that I need help. So if you’ve read this and can understand my frustrations send me a little help in the comments. Or tweet me, Im going to solve this one way or another but I really don’t see why I should go it alone. Any and all help is GREATLY appreciated and will be properly honored.

UPDATE: In case you also, have a similar problem like myself I found SwitchResX’s User Guide floating around online, its not the current version but it may help some of you grasp the concept of how/why SwitchResX works, as well as some tips on what to do in certain situations.
