I've been looking for a monitor and got this one for free. It's a 22" Viewsonic P810 model #VCDTS21542
I'm doing my best to educate myself, but I'm still learning to navigating this site.
It has a VGA connector, but it also has these connector... I'm not sure what they are, or if I could use them...or should.
Could use some advice. The last 2 are H-sync & V-sync. what ever the hell there for... pic. included.
Thank you in advace.

they are rgb as indicated on the monitor...you could use them I suppose if you really wanted to...I would just use the vga port though if it were me. ;)
-
the actual connector is called "BNC"
the only reason you would use them is if it didn't have a VGA port or you where going to be using an arcade board (since it outputs RGB sync signals) if you are just going to use the monitor with MAME, just use the VGA.

Ohhh... That's "BNC". I thought they were call Stick and twist for some reason. The pieces are coming together.
So, then, from what I'm reading, I could use BNC, but the VGA port is better. You know sometimes you need help with the simple things before they make sense. This site rocks! :cheers:

Used to be the higher end equipment would use BNC connectors it's supposed to have a better image here is some more info.
Oh and here is the cable also

Should I use a VGA to BNC cable if my monitor has BNC connectors?
(The following assumes a normal video card with a mini-DB15 VGA/SVGA connector - if yours has BNC connectors, the improvement may be even greater.)
The answer is an unqualified maybe. In principle, the BNC cable should have higher bandwidth and better transmission line characteristics (impedance, termination) and result in sharper crisper images with less ghosting, ringing, and other artifacts. However, this will only likely be significant at higher refresh rates (1024x768 at 75 Hz and beyond) and depending on your monitor and video card, you may see no change - or it may even get worse. It is best to purchase a good quality VGA to 5-BNC cable with a return privilage and try it. I suggest a 5-BNC cable even if you only need 3 or 4 connectors so that it will be compatible with any monitor or video card you might have in the future. Cost should be in the $25 to $70 range.
Potential advantages of using the BNC connector inputs on your monitor with a good quality cable are:
higher video bandwidth -> sharper display.
proper connectors (at one end, at least) and correct termination implies less ghosting and ringing.
For a good monitor with a high quality video card, the difference can be dramatic - as is the case with my ATI GPT and NEC 5FG.
