Marshall 7" R70P-HDA monitor + Color Bar Test

Hi guys. Can anybody who owns an HVX200 and a Marshall 7" R70P-HDA monitor run a quicky test for me....

The HVX200 should be recording and displaying in the viewfinder 0 IRE as all DV & HD cameras do. You know this because you should be able to see the 3 PLUGE bars in the lower right corner of the color bar screen representing superblack, black & grey. Also the composite, s-video and component outputs should be spitting out 0 IRE as well.

Well see, what I'd like to know is if the Marshall monitors are running at 0 IRE or if they are compensating by adding 7.5 IRE like most all US televisions and HDTV monitors do.

SO CAN YOU DO THIS: Plug your Marshall Monitor up to your HVX200 via component/RGB and turn on the color bars from your camera. If you can see the 3 PLUGE bars on the lower right corner of the color bars on the Marshall screen then GREAT. this means the Marshall is not compensating and correctly running at 0 IRE for DV & HD cameras. Turn up the brightness on the Marshall if need-be. it should look like the picture below:

F.Y.I.
This is the reason why using a regular HDTV as a field monitor for color correction & exposure is *not* good. Barry has repeatedly told us that cutting corners by using cheaper home TV's is not good and to get the right tool for the right job. For example, the Dell W1900 HDTV is a great buy, but like most US televisions, it compensates by adding 7.5 IRE to the inputs. *a bad thing* So DO NOT use this montor for your DP. it is good for shot setup and video village for your director. Also it's cool for focusing, but NOT for exposure or color correcting. Any monitor you use you'll want to see all 3 PLUGE bars.

I'd like to know if the Marshall Monitors show them.
 
ALSO, it would be cool if you can connect the component "AND" the s-video connections to the Marshall Monitor at the same time, and then A/B compare the two images. I wonder if the Marshall's component connection @ such a low resolution (800x480) will actually be any better then the S-Video connection visually.
 
Hi Shannon ! I'm afraid I'm not getting any of the pluge bars, or even the lower portion of the color bars just straight color bars.
 
Yea component out from the camera. The color bars on the cameras LCD itself look nothing like the picture Shannon posted, just 7 straight bars with nothing else below ??
 
Ray, looks like your monitor is compensating at 7.5 IRE. What equipment are you using exactly? Camera? Monitor Model? Type of Connection?

Carlone, if you are using the Marshall on your HVX, that's great news.

Also, it looks like my "IS COMPONENT BETTER THEN S-VIDEO ON THE SAME MONITOR AT SUCH A LOW RESOLUTION?" question has been answered by a comprehensive report from the master blaster.....STEEV DINKINS! Read it here:

The short answer: The Component inputs are in fact visually better then the S-Video inputs.
 
Is the Marshall HDA monitor well worth getting then? I showed it to my DP and he thought it may be too low-rez for critical focusing.

Over here in the UK it's close to £1300 for the monitor + a further £400-500 for the V-Mount batteries/charger so we need to make the right decision. This isn't being made easier because the DVRack plug-in is out soon which will turn our laptop into a very nice field monitor.

These are the bars in PAL land.

It doesn't always include the red "Bucket of Blood" bar at the bottom. It would make since that the PAL version of the HVX just shows the 7 vertical bars.

The split field bars with PLUGE are for NTSC
