Re: Which 50Hz monitor ?

I have two Viewsonic 1920x1080 monitors that work.

Go to TigerDirect.com and pull up the Viewsonic models and they list the frequencies.  The only ones by Viewsonic that didn't do 50Hz (they were 56Hz) were the 2 older "square" ones.  All the widescreen models I checked seemed to be 50Hz, but do check the models yourself.

I'm very happy with the ones I have and they work with PAL screenmodes on my A4000 (with IndivisionAGA, so it would anyway), Minimig and A2000 (using an "Amber" SDFF - which uses the same Amber chip as the A3000).
A2000, A3000, 2 x A1200T, A1200, A4000Tower & Mediator, CD32, VIC-20, C64, C128, C128D, PET 8032, Minimig & ARM, C-One, FPGA Arcade... and AmigaOne X1000.

I have a BenQ G2400WD and they actually take the 50Hz and in "information" on OSD says 50Hz. BUT: When I boot Workbench, the lower part of the screen is somehow "outside" the image...it is too far on the bottom so I cannot see it. And if I enter OSD and change Veritcal Position so that it is all the way on the top of the LCD, I still can not see the lower 10-15% of the image. I can not "shrink" the vertical size either.

Any tips ?

Have you made adjustments in the OVERSCAN prefs?

But changing the overscan will only give you LESS desktop-size, and is that something you really want ?

PLUS: In games and non-wb environment, this is not a solution either :-\


You can use it to move the visible area around the screen to a point where you should be able to adjust the V&H holds on the TV.

It is very easy to use overscan to make a screen size bigger than your TV can adjust to.  The question is to the stardard PAL screen modes fit BEFORE using overscan?  They should and then you use overscan to maximise them withing the confines of your TV's display.

BTW: Are your Viewsonic monitors 16:9 or 4:3 ?


16:9

I can either stretch the image or have the black bars for native modes.

Personally, with the A4000 I have a 1920x1080 Workbench via RTG on the DVI input and then "stretch" the native modes by choice over the VGA input.
A2000, A3000, 2 x A1200T, A1200, A4000Tower & Mediator, CD32, VIC-20, C64, C128, C128D, PET 8032, Minimig & ARM, C-One, FPGA Arcade... and AmigaOne X1000.

Cool. I found a dealer for Viewsonic (well..many actually) but I do not wanna order a model which won't work :) So what is the model on yours ? I know it's probably off the market already...but, as a reference.


I have 2 of these:
Viewsonic VA2223wm 21.5in 1920x1080 5ms DVI SPK

Like you say, discontinued now but there are lots of newer models.  Just check the specs.  :)
A2000, A3000, 2 x A1200T, A1200, A4000Tower & Mediator, CD32, VIC-20, C64, C128, C128D, PET 8032, Minimig & ARM, C-One, FPGA Arcade... and AmigaOne X1000.

Yes, but the overscan settings you apply is under workbench environment. If you boot a game/demo off a adf file, then it will just use "ordinary" PAL setting like it is within the early startup sequence menu.  Am I right ?

So -- to be sure that things work 100% with the LCD, then I need a monitor which can show the whole screen even before a WB is loaded. So I think I will try to order one and ...well..just see what happens :)

What I do to set up a new monitor is to load a PAL floppy based game, use the H&V holds on the TC to center the display, then I boot to workbench and use overscan to stretch that screen mode to cover the largest area and use the H&V size on the TV to make sure it fills the screen.

You will probably have to adjust each different screen mode if the monitor remembers the different H&V settings for each mode.
