Sounds like some very good things but one possibly bad for my intended purposes.[quote]It doesn't accept interlaced input (480i/576i/1080i)...
Does this mean if I want to hook a TV tuner up to it like the OnAir HDTV GT I cannot get 1080i broadcasts?
If you mean
this, then it won't be any problem. It goes through the PC, so your GFX will send it to the screen as a progressive signal. Most newer external equiptment have their own interlacer/deinterlacer, so you can choose if to output interlaced or progressive signal regardless of input signal. Its only if you have old equiptment that doesn't output progressive signals this would be a problem. :)
Does this mean you could basically use ANY common game res regardless of aspect ratio?
I'm not sure what you are asking about here. Yes, I can use any common game resolution regardless of aspect ratio. I can choose for the signal to be displayed without scaling (1:1), scaled to full vertical height while keeping aspect ratio intact (scale to aspect), scaled to full screen, or choose how much I want it to scale horizontally and vertically. On custom there is also an option to change input signal on the screen to counter any overscan in the signal (H. res and v.res). I can also select where I want the image to be on the screen with H position and V position.
I also have a couple other questions. How do you watch letterbox movies on yours? Do you zoom it or leave it 1:1? Reason I ask is I'm not sure I would like having the huge black bars top and bottom on a 16:10 screen. It's bad enough watching letterbox ratio on my 16:9 HDTV.
It depends a bit. I do both. Sometimes I use Zoom Player, where I can zoom quickly in and out by scrolling the mouse and sometimes I use different settings in media player classic. Or I just let it run in windows media player. :)
Also, do you know if the Planar has that kind of scaling capability or would I be severely limited on game res? I kind of thought the Planar was critiqued too harshly. Maybe some expect too much from it having the same panel as the NEC. The scaling really matters to me though.
Unfortunately, there are little reviews and in most forums they speak about its capabilities for graphical work. In this review, he talks a bit about gaming and scaling though:
Planar review
If I do end up getting just the NEC display itself, can I use the Spectraview for 14 days to fine tune it or do I need to have special hardware? Looks to me like there's a lot of stuff you can tweak in the software even without calibration hardware.
You need a "puck" or hardware calibrator. Spyder2express is among the cheapest and most is compatible. If you know someone who has one, you can borrow it. Otherwise, there are several presets you can change and extremely many options to tweak the image. For movies, you'll like the 6-axis saturation option which goes great with cartoons and the black level slider which gives greater optical black (but at the expense of black level detail).
Anyways I probably should mention that I plan on this system having a 9800GTX and Nehalem 45nm quad with integral memory controller, so it may not be until the end of the year before I can build it.
I'm also waiting for the 9800GTX! :D Take your time, more screens can show up that you want more. But, then again, there comes always a "better screen". I'm really satisfied with the NEC though, so I'm spending my budget on GFX next.
