suitable monitor?

[tholin]

Hello everyone, I'm new to this forum and need some advice.

I'm planning to get a new monitor in the near future and suddenly I got this brilliant idea. The idea was of course to hook up my consoles to the monitor which lead me to this site. I've read the primers and posts on this forum and would like to confirm my suspicions.

The monitor I'm planning to get would be a tft widescreen model but finding one which could handle vga input sync of 15khz will probably be difficult. There are however monitors with composite, svideo, and component inputs. The gamesx page got guides how to get RGB signals from most of my consoles. All consoles are PAL versions and I can get RGB from the never ones from the scart cable. The problem seems to be that RGB != component even if component cables have red green and blue color.

To connect the RGB to the component input of the monitor I would need something like this:

I do have some basic soldering skill but I don't have a volt meter or signal analyzer. Are there any ready made RGB->YUV converters I could get for a reasonable amount of money? How good would they be and what problems can I expect?

I looked at a LG L246WH monitor with composite input. There is no separate sync signal so I'm guessing it use something like sync on green (or the green wire). Will that be a problem?
The manual has this table:

Component Video INPUT
Display Modes Horizontal   Vertical
(Resolution)  Freq. (kHz) Freq. (Hz)
1      480i     15.75       60.00
2      576i     15.62       50.00
3      480p     31.50       60.00
4      576p     31.25       50.00
5      720p     37.50       50.00
6      720p     45.00       60.00
7     1080i     28.12       50.00
8     1080i     33.75       60.00

The first line looks like NTSC and the second PAL. Will the monitor be able to sync with all my consoles. I have: Nes, Snes, Genesis, N64, PS2, Gamecube. And what about other consoles? (assuming I can get RGB signals from them)

The manual also has this table:

It can sync on ~15khz?
If I understand things correctly HDMI = DVI + audio and DVI can carry both digital info and an ordinary VGA signal containing RGB pins. But looking at the HDMI spec I can't find any analog pins. Wikipedia say that HDMI is not backward compatible with DVI-A (analog) but why would the manual list analog sync frequencies if HDMI only has digital pins?

Do any of the things I say make sense? Anyone have a setup similar to this and how does it work? How bad is the lag introduced in the analog->digital conversion in the tft monitor? Other comments about this idea?

DVI may be digital, but it still has a sync.  Everything needs to come out at a set constant rate from the video adapter, even if nothing is moving on-screen.

I once saw a CRT with DVI input (and it was not DVI-A, it was DVI-D).  I wish I bought it.

Yea i saw something like this about a year ago. It was a 24" widescreen CRT monitor with DVI.
It was posted on craigslist as a multimedia/photoshop monitor. The guy wanted like $400 for it and i didn't have the cash. Still, nothing really beats my two 24" LCD monitors side by side
