One of your devices is passing black level as Level 0 (the PC) and your Playstation is passing the black as video level 16. Basically this means your brightness (black level) and contrast (white level) are going to be out of whack on the PC. So the brightness control on the projector or video card is what controls your black levels, and the contrast the white peaks. Go into the NVIDIA or ATI control panel and just adjust brightness and contrast, or change the video level in the control panel (if that setting is in there, forgot what they call it in there). Generally, cut the brightness control on the PC (from video control panel) at about half or so, and you may also need to adjust the contrast control a bit. You need a pluge pattern though to check it properly. Here is a pattern generator for the PC: http://calman-htpc-pattern-generator.soft32.com
(it tries to install AD junk, so choose advanced install and uncheck the advertising stuff).
You can also use the AVS Rec 709 disk which has test patterns (Google it for the download).
As far as to how to handle the installation with that low ceiling (besides returning the PJ), well you're going to have to fudge it a bit. The best option is any of the below 3 (or combine them);
1) You can fudge the install a bit by over-zooming the image and you just have a little bit of overflow into the black border areas of your screen. This will overflow the geometric error so that it won't be nearly as noticeable. Most screens have an inch or two of black border around them allowing for some installation error. This can allow you say about 3" to 5" of a lower offset (maybe more).
2) You can in some situations tilt the screen to counter the geometry (mostly with fixed permanent mount screens). For instance, as you tilt the projector to allow it fit in that low ceiling, the image will be geometrically off, but this geometry problem can be countered by tilting the screen towards you a little.
3) You can use keystone (but I'd keep it minimalized). If all else fails this is the easiest and most flexible of the 3 solutions.
You can buy a good HDMI switch for $40 or less if you're receiver is flaking out the HDMI, Denons are notorious for this.
