Thread: Sharp 7" 16:9 widescreen update and help request

Laxrox, are the mods, modw, and modn easily modified? are there dip switches easily accesable? are there dip switches accessable if you take the case appart? do you even now where these things are so that they can be modified high or low. ime sorry if this is answered in the data sheet. I dont have a printer and my eyes hurt from reading it off the screen. also do you know what mode the redant sets the screen in if it is not adjustable? probably wide 1 mode but it would be really nice if they came cinima mode.

laxrox, I think you should check the LCD pins for signals like you said. The LQ070T5CRQ1 has a lot of nice features that I am not sure would be in the Redant unit. Your pics of the unit show an NTSC decoder daughter board, but the 'CRQ1 has a decoder built in. That and the wide-mode switching or external separate H & V sync may be missing. Check it out. If the 'BGO1 has the H & V sync in then it would be easier to connect to a VGA output. Most all video type of LCD's are fixed-frequency displays and require "NTSC" or "PAL" timings to operate whether using composite or RGB signals. A VGA adaptor would need to be able to put out 640H x 480V x 30Hz Interlaced in order to display on these LCD's. The displays 1440H x 234V dot resolution has nothing to do with the required video signal format, the 1440 is 480 each of R, G, & B pixels across, and the 234 means that each video field of 240 lines (NTSC) is displayed on the same pixel row minus some lines that they throw away. Okay I'm rambling, but the display may still do you good, you just need to get it the RGB & Sy in some form or another. Oh-yeh, that part 3 of section 7-3 stuff is about the specs of an external clock that the 'CRQ1 need if you are giving the display external H & V sync. That would be a bother but not impossible, first find out if the Redant unit has this function by tracing the circuits and scoping it out. The Sony XTL-770W display on the stupid web-page is a similar Sharp display with the wide screen mode-change features, some modes would be useless for PC desktop display as they would cut-off some of the image but a DVD or VCR video image with letterboxing built in can be stretched to fill the screen and look "good". I wouldn't mind a stretched PC desktop in any case as most everything looks "good" stretched out, kind of like "the future". ;-)

bump and question...
Could this be modified to accept S-Video input easily?? Since S-Video is better than composite ( no color bleeding). It seems to have input for Svideo or am I worng?
what you think laxrox?

If we used a composite(RCA) to s-video adaptor, would be have the better quality of S-Video?

The short answer is no. Simple S-Vid to Comp Vid or Comp Vid to S-Vid adaptors are only meant to provide a way to get a signal in or out of a box if you do not have the proper connection on the other box or the proper interconnect cable.
The adapters use filters to separate or combine the Luminance & Chrominance signals for the S-Vid connection. S-Vid looks better than Composite Vid, but if the signal started out as Composite Video, it will always look like Composite Video of worse.
