T85A (AKA part # 9519-AW1 ) from IBM has this feature. It can display resolutions as either expanded to full LCD resolution, or just fill the pixels on teh screen that correspond to the original resolution. It only goes up to 1280 X 1024 though.After many, many hours of searching, I finally found an LCD display that should work. The NEC LCD2090UXI is a 20" 1600x1200 display that offers:
- EXPANSION: Selects the zoom mode.
- FULL: The image is expanded to 1600 x 1200, regardless of the resolution.
- ASPECT: The image is expanded without changing the aspect ratio.
- OFF: The image is not expanded.
- CUSTOM: Refer to the ADVANCED OSM Controls section of this user’s manual for detailed instructions.
So that's exactly what I'm looking for. Now to see if I can find one or one that's equivalent. A 1600x1200 display would be pretty sweet. Only concern I have is whether those options are available over VGA and not just DVI.
A word of warning: Those NECs mentioned above are a decade and a half old now. I have one of the 20" 1600x1200 ones in the garage that I trashpicked because, yeah, at first glance it looked awesome featurewise, but it didn't take me long to realize that there has been a *lot* of water under the LCD monitor bridge since those were made. Not only is the "best case" color reproduction and contrast of the LCD not that great, there's a good chance that a used one has a *lot* of miles on the old CFL backlight. I would strongly recommend seeing a monitor of this age in person before ponying up any money for it. There's a fair chance the display will leave a lot to be desired.
Yeah, after they cleared out from their first use owners, they seem to have disappeared from the market.@trag 1280x1024 is perfect. Unfortunately that model IBM panel appears to be pretty rare.
I was parting out a 17" display just to be rid of it because it was too dim.***** All I wanted were the speakers, but it turned out the backlight sheeting was fine. Could adaptation/cannnibalization be reasonably straightforward in your case? I've always wondered if those sheets could be cut down from two sides and retain function of the reduced size panel?I may pick out the runt of the litter and try replacing the backlight tubes on it and see how that goes.
Check out the specs of the HP PL766A I shared it between HP_Mini and the VGA capable Macs on the display. THaven't looked for the manual yet, but title looks promising anyway?Edit: It's only on their widescreen displays. :/
Custom Scaling (select models) Selects the method on how displayed information on the monitor will be formatted. Select:
- Fill to Screen - image fills the entire screen and may look distorted or elongated because of nonproportional scaling of height and width
- Fill to Aspect Ratio - image is sized to fit the screen and maintains proportional image
- One-to-one - disables video scaling, displays an image that is smaller in size than the monitor’s capability and centers the image on the screen in the active viewing area
I'm thinking that perhaps having a small database of LCD monitors that support this feature would be useful to not just Mac users but any vintage computer user who wants 1:1 pixel mapping on a monitor.
That's just the usual clock, phase, V/H position. No options for scaling.
I recently bought a super-cheap LCD/Scaler combo that uses a Realtek-based scaler chip that's ridiculously widespread in the cheap boards. I've done digging on the "RovaTool" software mentioned a lot in this guy's posts and I have been wondering if it's worth trying to tweak it, since its out of the box configuration is less than optimal. I don't have the link handy, but there's actually a tool out there that can program the board without a separate programmer if the board has a VGA port wired according to the reference design. (It can pass SPI through the DDC channel.)Arbitrary resolutions and scan rates for the target LCD, programmable by the user not the seller
