I found a 960 for a very good price, but I don't think I'll be buying it anymore. 1080i (AKA 540i?) only? No thank you.
The 960's input electronics support INPUT source resolutions of 480i, 480p30, 720p60 and 1080i source. You cannot feed it 1080p.
And of course, its composite and S-video inputs support only 480i input. For 480p, 720p and 1080i, you must use either its component video input or its HDMI input.
The 960 has a "native resolution" of 1080i. That means it has a maximum of 1080 lines of electron beams projected onto the screen by the electron gun, and that at that maximum resolution there will be alternating "interlaced" sets of the even/odd 540 lines at a time, each set of 540 lines sent out to the screen 30 times per second. A CRT monitor can display an image at any "display (aka "source input") resolution" at or below its maximum "native resolution". The electron beam is "scaled up" if necessary in order to utilize the complete 34" diagonal screen area available for the image being displayed, subject to some service menu adjustable "overscan" around the perimeter designed to reduce negative visual artifacts of projecting the electron beam from a conceptual point source onto a flat rectangular screen. The adjustable overscan "magnifies larger" the actual displayed image typically anywhere from 0-10% to try and eliminate the worst artifacts which appear at the extreme edges of the electron beam image which are now no longer physically visible on the screen.
Because scanline-based CRTs are analog in nature they can vary their display CRTs provide a variability in resolution that fixed resolution pixel-based LCDs cannot provide. The 960 eliminates its "interlaced" function when the input is 480p, so 480p30 input (e.g. from old video games) is presented using 540 display lines (which holds the complete 480 lines of source input) 30 times per second so that there is no visible "flicker" at all. This is what made (and still makes) the 960 desirable for early gamers. As a matter of fact, I was able to sell my own 960 last year (located here in LA) to a buyer in Oklahoma who was willing to pay for crating and shipping (by a mover) halfway across the country, so that he could have this set for him and his son to play old video games on... at a "true progressive 480p" non-flicker no-delay only possible with old analog CRT-based sets.
So you could say 480p30 input is displayed at a "native 480p" within 540 screen lines completely refreshed 30 times per second. Zero flicker. In contrast, the 960 displays the 1080 screen lines of 1080i input exactly as one would expect, namely displaying all 1080 lines of input as two alternating interlaced sets of even/odd 540 screen lines, presenting each set of 540 lines 30 times per second.
720p is obviously its own problem for an analog CRT that has 1080 screen lines to display content and a maximum refresh rate of 30 times per second. My old Sampo set actually had extra electronics in it to provide "native 720p60" HD support. That means (like how 480p is handled on the 960) it would display all 720 lines of source input using the 1080 lines on the screen, refreshing those 720 lines 60 times per second, which is what 720p60 HD demands.
The 960 doesn't contain this electronic capability for "native 720p60" support as it can only refresh the screen 30 times per second. So it converts 720p60 input into 1080i for display, displaying alternating even/odd 360 source input line pairs at a time, within two pairs of 540 screen display line sets, with each alternating set of 540 lines refreshed on the screen 30 times per second. Yes, input 720p60 is accepted, but it is not displayed as true 720p60 like the Sampo did. Instead 720p60 HD input is interlaced by the 960 electronics for presentation, and is displayed as interlaced 1080i.
(I'm pretty sure I've got this right).
