Sony PVM-20L4 resolution

Post by Stan »

According to the last page of this flyer
http://www.pmotions.com/Public/PDFs/SON ... (brch).pdf
it has a resolution of 800 TV lines.
But the scanning frequency is mentioned with 15.734 kHz

My question: does it support VGA resolution?

You need 800 TV lines to display anamorphic 576i. The monitor supports 15khz only.

Ok, it means it will display the anamorphic 576i, but will not display 480p, right?

that's right, 240p, 480i, 288p and 576i only. All in 4:3 and 16:9. I'm just getting a 20 F1E myself.

I'll expand:

800 TVL on a 4:3 monitor means that you should be able to send it a 1066 x 240p or 1066 x 480i signal, and the monitor should be able to resolve that horizontal resolution. It's usually related to how fine the dot pitch is in the shadow mask.

I believe the test is only for the center of the screen, where the crt is the sharpest. So if you tried to display 1066 alternating white/black columns. It would just look grey towards the sides.

Thanks.

Do you know if it will accept "standard" RGB-signal (from DVD-player or console) from SCART using a BNC adaptor?
I am not sure, as in the flyer it also says "Sync on G"...

RGBs is ok, but you need clean sync, meaning that if your source does only provide composite video as sync, you need to run the signal through a sync stripper/cleaner.
