Dream Authentics LCD Claims

Ummon:
I don't follow that one. Tons of each, neither liked. Quite good as fodder.

For you 2600 (and other) gamers out there, I got one of these about 7 years ago and it worked a million times better than that crappy RF box.

I paid about $1 for it then, but $5 now still seems like a steal to get one.  Also, the picture was much cleaner with this than the RF box I had.

Not meaning to step on any toes, tick anyone off or say anything to start a fight! :)

I have a 22" CRT in my cab right now, but in defense of LCDs I had a 26" LCD hooked up to my primary personal computer (not to be confused with PC, but my own PC, not my work setup) and it literally has been running 24x7 since 2005. 

When I say 'had', it doesn't mean it died.  I replaced my main computer's 26" LCD with a 32" LCD and moved the 26" over to my secondary system in my computer room.  It is still working perfect and just as bright as ever and not a single bad pixel.

I personally wouldn't have any problem switching to an LCD in my cab as far as fear of failure.  BTW, I bought my 32" LCD AND a 22" LCD for my work PC (Both 720p HDTVs with PC inputs) for less than what I paid for the 26 incher four years ago!

Will I have them 20 years from now?  Probably not.  But I doubt my 22" CRT will last that long either.
Bluedeath:
LCD panel itself (in theory) lasts almost forever what gets dim overtime is the backlight but replacing it costs more thank buyng a new one. Panel controller tends to die more for bad assembly than from the ages.
Said that unless you are buildiong a cab to play Street fighter4 /street fighter vs tastunoko o soldner X (that are the current generation arcade cames and are 16/9) i would use a CRT.
AndyWarne:
There are quite a few issues with the original statement.

The very first arcade monitors were TVs with the RF and other unnecessary parts not fitted to the PCB.
Then the next variants, the most common, were based on TV electronics but with specifically designed chassis. Thats why they are 15Khz scan rate, as a TV, and they used TV CRTs. CRT tubes used in all the classic arcade monitors are TV tubes.
It also explains why they needed isolation transformers, as they used the same design of very simple non-isolated power supply as a TV.
 
LCDs will not be damaged by gaming. Plasma screen might be an issue when displaying game-type graphics over a very long period of time but not LCD.

LCDs which can accept 15Khz horizontal scan have been around for a while and are extensively used in Asian arcade cabs.

Its not the case that LCDs cannot display anything other than certain vertical scan rates such as 60 Hz etc. They do often have built-in limits but they will generally go down to around 45 Hz. The min horizontal scan rate is usually limited to 30Khz though so you cant connect a 15Khz source to a standard LCD screen, you would need one of the special 15Khz-capable ones.

But there is not really any point in getting a 15Khz-capable LCD for Mame because the picture will not be any different to a 31Khz one, and not be any closer to a CRT picture, where each scan line is a game pixel (when using native resolution). The LCD will have a large number of physical screen pixels per game pixel. If you run at 31Khz it just means twice the number of LCD pixels, vertically, than there would be at 15Khz.

Thats not to say there is no advantage in using native resolutions on an LCD screen. There is almost as much advantage as on a CRT screen, because no stretching is required to be done by the VGA card or Mame.

CRTs are almost history as eventually the last CRT tube plant will close and that will be the end of it.

Golden Tee, which are probably the most common real coin-op video machines are now using LCD.
