Is there a 720x576, 7 inch monitor? at DVinfo.net

Rafael Lopes · January 31st, 2007, 12:51 AM

Hi,

Was I've looked into dozens of portable 7" monitor these few last days and they all seem to have weird resolutions like 1440*240 or something like that. I was wondering if anybody know if there actually is such a thing as a 7" 720*576 monitor out there? I'm so desperate that I even started looking into some DVD players to see if they met these specifications.

Oh, and apart from this mains problem. None seems to have a compatible video input . All monitors and dvd players I check have only an AV IN mini jack input, and the Canon A1 ouputs RCA, BNC, FIREWIRE, COMPONENT (and with an adapter it could output S-VIDEO). Actually the A1's RCA output is RCA in one side and AV mini jack in the other side (the side that comes out of the A1's body), but I couldn't find any cables that are AV mini jack in and out.

I was hopping not having to spend MUCH more than 200 EUROS.

I think the answer is no.
Probably because video isn't displayed at 720x576 anyway.
SD 4:3 PAL is displayed at 787x576 and SD 16:9 PAL is 1049x576.

The video itself always contains 720x576 pixels but they're not square pixels. The pixel aspect ratio is changed between 4:3 and 16:9 however LCD screens only use square pixels so to get the display res you have to multiply the video res by the PAR of 1.0926 for 4:3 or 1.4568 for 16:9.

So, what would be the closest I could get?

here my new DIY 7 Zoll LCD fieldmonitor, 800x480 pixel (16:9) for SD PAL/NTSC.

Wolfgang, have you tried just one battery pack on the LCD screen? I find most of these LCD panels work fine off of the typical 7.4v coming out of camcorder batteries (much to my amazement). I powered mine for a while with JVC batteries.

Wolfgang Winne · February 20th, 2007, 12:45 AM

<Wolfgang, have you tried just one battery pack on the LCD screen?

Yes, but this monitor works only correct from 9,5 - 14V.

Do you need 720x576 specifically? What video outputs do you want to use? Here's an ikan with 800x600:

Here's another ikan with 1024x768

How much portability do you need? I don't think any of these monitors will help with focus if thats what you are looking for. You're gonna need to pay over $1000 US for a decent monitor to pull focus with.

If that isn't an option. Get an LCD with sharpness adjustment. Crank the sharpness up to max. I use a cheap LCD for legal depositions and I found that if you up the sharpness and train your eye you can get decent focus on a cheap LCD. It is similar to the peaking function (not as good, but similar) on the XH-A1.

Sorry Wolfgang, I wasn't including your monitor, nor did I mean for it to seem that way. :)

James R. Leong · February 20th, 2007, 03:01 AM

What about this one for the XH-A1? It is a portable PC monitor 1024 x 768 but I don't know if the RCA input will give you that resolution.

Tony Tibbetts · February 20th, 2007, 03:07 AM

Isn't 1024X768 a square (4:3) resolution? That LCD looks widescreen. I'm pretty sure those specs aren't accurate.

Wolfgang Winne · February 20th, 2007, 03:58 AM

<It is a portable PC monitor 1024 x 768 but I don't kn...

this is not the native pixel resolution.... 7 Zoll 16:9 has max. 800x480 pixel, the most 7 Zoll LCDs have the same electronic from china inside. 1024x768 is only for VGA Input, this resolution is downsample to 800x480.....
the best 7 Zoll HDV Monitor is " Marschall Electronics V-R70P-HDA - HD/SD 1.2 Mega Pixel"

Wow, 1.2 Megapixel !!!

My LCD:
800 red + 800 blue + 800 green = 2.400 Pixel

2.400 x 480 = 1.152.000 Pixel = 1.2 Megapixel

Here is a Marshall 7" monitor with 1.2 megapixels and 800x480 with many input options:

There are not that many DVD players with video input. Mine is a Philips PET-1000, which is quite good. It does have a composite video input, but as you may see on my recent thread it has its own problems too.

Perhaps you can get that model in Europe for the kind of money you mentioned.

For quality viewing you will need at least S-video connection, which is not rare in portable monitors. Component video is, and only the more expensive have it. But I think the S-video should be fine, if the monitor has good resolution. This you should try.

Not being able to try it was the reason why I didn't buy a Xenarc in 2005, so I got a generic model from B&H, then called TV-One.

http://www.visualcm.com/tvone/pdf/Sp...070-LTM104.pdf

Today I connected my Sony Z1 for the first time to it, and to my surprise the image was inferior to the one I got from the Philips PET-1000 DVD player. Which in turn provided better image when fed from my Sony PDX10. So go explain that!

But the Philips should provide what I want now, which is monitoring my frame while interviewing, having a cameraman or not to do it. On the first case to check what he/she is doing; on the second to check if the interviewee framing needs some correction.

The bad news last. I don't think you will find anything decent for that kind of money. Only to check the framing and not much more than that.
