its not really a huge deal when wathcing tv, though sometimes it is very noticeable.
My opinion is if it is noticeable at all then there is probably too much.
i end up adjusting the sliders and i end up with a resolution of 1622x925
The suggests fairly extreme overscan.
Would adjusting overscan in the service menu remedy my problem?
It could at least help. The reason overscan exists is to hide the geometric distortions and coarse edges that exist at the edge of the beam. If you want 100% viewable like on a computer monitor then you'll need to accept some inperfection. In my case, I would have had to have substantially underscanned the image to have shown 100% because of deflection issues. Your TV might have been better put together. Ideally, 0.1% overscan is preferable to 1% underscan because with long term use it might have a "ring" worn into the phosphers around the edges of where the beam has been.
There are alot of geometric controls in the service menu. It is like adjusting the knobs in an old time CRT computer monitor. Make sure you write down any setting before changing it so you'll know what the factory settings of your TV were.
Reducing overscan may make geometric distortions more visible and require adjusting geometry controls to correct for them.
Ive also done some looking around but havent got a clear answer on wether the xbr960 can deal with pc monitor use fine without damaging it short or long term. Some peoeple were saying that CRT's can get burn in issues or something >_<. Hoping that the 960 is such a beast that it can do anything it wants :P
CRTs' phosphers degrade with time so with more hours use the lower end of the gamma curve will become unresponsive and it'll lose shadow detail, although you can correct for this to some extent from external analogue and PC outputs with the right equipment or software.
If you double the number of hours you're using the CRT by using it as a computer monitor too then it won't last as long, especially with the bright white backgrounds favoured by computers. Pattern burn in from short-term use isn't very likely unless you leave a picture static for an hour or two. Setting a blank screen saver to come on after a minute idle should help. CRTs don't burn in as easily as plasmas but unlike plasmas the burned in artefacts can be highly persistant.
Whats the color axis setting about. I know it affects red's but whats the deal? Is it just preference?
Each input type / picture setting combination can have a different AXIS setting in the service menu. The AXIS setting, references four settings, RYR, RYB, GYR and GYB, that control how red and green are expressed. By default, there is a severe "red push" that reddens the picture horribly. In the service menu you can turn this off, as described in the service menu thread linked to above.
Try the following settings:
