how can I connect my VCR to my HP monitor
model A2094A which is hooked up to a hp 715/75

one answer could involve leaving the monitor attached to the 715/75
and another answer could involve hooking up the monitor to a PC with a video card

There is nothing in common between a TV or VCR and PC's or workstations. TV/VCR's are low resolution and have a unique refresh and interlace. Although the screen may look like a TV, there is nothing inside the monitor that will sync to your VCR.

There are special adapters you can buy that allow displaying TV or VCR signals on a computer monitor.

This idea seems weird. A monitor is just a high resolution dumb device.It does not have the necessary receiving and amplifier ckts like the TV.You can connect the monitor to a PC which is normal and watch dvds with your multimedia kit. But I dont think there is any interface in the market which connects the TV to a VCR.
Why some one would buy a monitor and the interface if any with the VCR when you get a good TV with std features for less than $250 bucks.

The cheap (read "cost effective") answer is: you can't. Here's why:

According to...
http://www.monitorworld.com/Monitors/hp/A2094A.html,

the A2094A monitor has the following specs:

Max Resolution: 1280 x 1024
Sync Type: Separate Sync
H Freq/ V Freq: 78khz/72hz
Connector: 5 BNC

The output of your VCR is either NTSC (if US) or PAL (if Europe). NTSC's V Freq is 60hz (frames per second) interlaced. PAL's V Freq is 50hz interlaced. Since the A2094A is a single sync monitor, it will need a storage device to store a frame at the slower rate and output it at the faster rate. Combine that with the fact that the 2094 uses 5 BNC connectors which apparantly equates to a separate line for red, green, blue, vertical sync, and horizontal sync. I don't know if your VCR is commercial or consumer, but if it's consumer it provides only a composite sync video or at best an S-video feed, and you have a bit of work to do to get it broken down to RGBHV signals. There may be some adapter available, but expect to pay $$$.

Here is a useful FAQ on the subject:

especially look over:
5.3) Watching TV on a PC monitor - NTSC/PAL to VGA

and remember that this relates to _VGA_, not the 2094, which uses a higher set of sync frequencies than VGA.
