LCD monitor with 1280x960 1:1 pixel mapping?

[Yglika]

Hi.

 

I'd like to get some (preferably 14", 15", 17" or 19") VGA LCD monitor for my Atari Falcon. However I want exact pixel mapping for 640x480 resolution what means I need a monitor with native 1280x960 matrix. However it seems there are only 1280x1024 monitors available. That would be fine *if* they can be set *not* to stretch 640x480 to their full vertical size but leave 32 pixels high blank strips up and down and so map every 640x480 Falcon VGA pixel to a perfect 2x2 square of their native resolution.

 

Is there such monitor at all?

Just to note that it may depend from attached computer and even video cable too. I did not look for exact details, but my LCD monitor has narrowed pic, so correct AR with TT - via regular VGA cable, while with Falcon it is full width, so not proper AR.

Then, you will have never exact pixel match/mapping with analogue cable, from analogue video output - talking about horizontal one.

Even modern PCs with the amount of control offered over the video signal, you can't get an LCD monitor to map 1:1 when using analog VGA.

 

The other thing - when you're talking about the ST/Falcon video, then you'd want to take the visible border area into account as well.

So, instead of 640 horizontal pixels, it'd be something more like 800.

The ST modes that work on TVs are based on progressive versions of analog TV signals, so you're probably looking at 313 (Pal), 263 (NTSC) - double each to take interlaced frame into account. Then subtract about 40 from each for VBlank/VSync.

 

If you can attain a close to 1:1 mapping you'd likely have less fuzzy pixels - also you'd want to take aspect ratio into account. Most modern LCD monitors are either 16:10 or 16:9 ratio. If you get a widescreen you'd probably want one with the option to squash the video into 4:3 AR so the pixel size is correct, and you'd need to take that into consideration for your resolution calculations.

Been looking into an RGB monitor upgrade as well. 1224's just don't cut it with vision loss due to age

 

This link has some decent info.

About a year ago, did find some surplus sites with medical quality monitors that would sync to 15Hz, even dated, the business were still asking a high price.

Also found an industrial recycling site (China) that offered chassis mount LCD monitors which could scan down to the beloved Atari scan rates. Bookmarked the site, went back just a month ago, site stating it was no longer available. Think getting in touch with some of the Hong Kong based retailers on the big auction site could lead to a find. The business model they follow is not only to list items they carry, but will also search other business at your request. Might be an option.

 

The Sony's take up a lot of real estate, especially if you're a typical Atari fanatic with two or three octopus machines on your desk

 

With the wife's permission looking into a Sony BVM-D24E1WU 24 inch. (PDF Manual attached). Expensive, must be careful of units near end of life when purchasing.

 

Laying out desk space, a desk unit to house all the Atari computers up and down each side, with the monitor centered on the desktop.

Of course, the CatBox outfitted Jaguar will surely have it's own connection to the monitor.

Just have to swallow the initial cost. Once set up, sure initial cost will fade just like a bad divorce

 

 

Thread's not too old, and subject covered many times in the past, think it worthwhile to keep it going if just not for "warehouse or liquidation" finds. (funny, misspelling "warehouse" gets your first spell checker corrected word as "whorehouse" ).
