I have had my s715 for a couple of days. I also have the f510 (I bought the s715, but then got a great deal on the f510, so I am deciding between the two right now).
Here is my question. On the f510 117 point convergence grid, I can see all of the lines, whereas on the s715, the very bottom line is off of the screen. It is below the field of vision so that when the cursor is over this line, I can see only about half of the upper line on the cursor. I assume this is not normal and it is surprising that the entire field shows up on the f510 but not the ultravision s715.
Is this something that may settle in after another 50 hours (I only have about 15 hours on the set now) or will the likely remain until I adjust it? The top line seems to be in the same place on both the f510 and s715, but for some reason the lower line is missing on the s715. In fact, I can see a bit of a line below the lowest line on the f510 (there is a very small gap between this line and the lowest completely visable line.
Should I even worry about this? I know there are threads dealing with geometry, and I have tried to work through them, but find them quite confusing. Before I actually study these threads for several hours, I would like to know if this is something that may chance over time and whether this is worth the effort (i.e., is this error in the signal acceptable?).
Otherwise, I think both are very nice sets. I only have one hooked up to a video source at a time, but I can compare the convergence patterns. Aside from the missing line on the s715, the s715 does seem to be a bit sharper when displaying these lines. However, it is not that big of a deal (I can't really tell any noticable difference when switching between tvs on a HD feed), so I am still up in the air as to whether the s715 is worth $400 more (I will probably not use the tuner or cablecard). The f510 seems like a great deal. I really do like the black frame on either side of the screen on the s715 though, really makes it sa much nice screen to look at.
