Title: 1084S-D1 vs. 1084S-D2
Post by: orb85750 on February 26, 2011, 12:02:22 AM
Is one any better than the other?

As far as I know, the D1 or D2 had a little nice green button up front, to change all the colors on the screen into an old school green scheme. I had both at one time. :)

Yes, that's the D1.  The D2 doesn't have that lovely feature.  Just wondering if anyone knows whether the D2 was an improvement in any way over the D1?  Perhaps some components were upgraded or the design was improved somehow to improve longevity?  (I have both, but I think my monitors may be taking up a little too much room here.)

The 1084S-Px models were made by Phillips while the 1084S-Dx models were made by Daewoo, they both used various tube manufacturers like Orion, Toshiba & Samsung... :)

The Dx part just refers to the different variations in the models sold, some had DIN connectors or SCART as the RGB input etc...

Not much difference in terms of the components used inside to be honest, the Toshiba & Samsung tubes are about the only thing to look for in terms of better quality (but not much)... :)

Best to keep the one that you consider yourself has the best picture and connectivity for your needs... :)

I believe that the 1084S-D1 could do PAL well (on an NTSC monitor anyway) but on the D2 it did not. (screen was not auto centered and was chopped off at the bottom)

The 1084s don't have "auto centering" any adjustments must be made by hand... :)

The only reason for the picture being chopped off would be the tube used itself, a PAL tube can display 625 lines while an NTSC tube can only display 525.

So while it's easy for a PAL tube to display a full NTSC picture an NTSC only tube will most likely crop the picture as it can only really display 525 lines unless the monitor contains some scaling circuitry... :)

I think the D2 has the best dot pitch and picture..

I have owned many NTSC 1084S monitors and used many others at friend's houses.  They ALL displayed PAL pictures without chopping off the bottom if you adjusted the knobs correctly.  Some versions of 1084S do need more adjustment than others but in the end they all work with both PAL and NTSC modes.

And I agree that none of them have auto-centering technology.

Yes I can attest PAL displays perfectly on all 1084s i've ever had, yes it requires adjustment manually (of course) These are vid monitors from the 90s. You also want to manually adjust your Overscan settings in Sys:Prefs/

I preferred the Original A1080 which was a Phillips unit, I found it to be a very robust unit.
The Worst Commodore Monitor was the 1802, I repaired hundreds of them.

You are right about the auto centering, none have that.  I meant the verticle, it auto centered between NTSC and PAL.  Never had to touch the adjustments.  On the D2 I had to do that as it was severely chopped off at the bottom by like 3"!

Regarding the PAL compatibility on the NTSC variant of the D1, does anyone know if this compatibility would extend to the PAL Commodore 64 being connected to it?

Having owned two of them, I seem to remember the D2 having a digital signal capability, like CGA or something. I got familiar with the manual after the original 1084S went all whiny and blew a flyback transformer and I seem to remember something about that.

Also I'd like to add, the D2 was *much* better quality. The original 1084 didn't last 4 years and the D2 was still going when it got boxed up and replaced by a flicker-fixer plus a Hansol flat-screen.

Yeah, i agree. I had the 1802 was very "fragile".

i think you are thinking of the 1902/1902a, one had the digital/analog switch

all 1084's work with commodore 128 digital rgb tho

My memory is not the greatest, but I swear I'd seen a 1084 hanging off the back of a Commodore Colt 286 one time.

I have three 1084S variants running at the moment. The P-VDE, D1 and D2. None have a scart connector though the P-VDE has a blanking plate which trust me does not have a scart behind.

The P-VDE has the circular style DIN RGB whilst the others have the traditional monitor connector.

The D2 and D1 are kinda the same except the D2 does not have the Analog TTC button at the back nor the green screen button at the front. The display controls are just a different way round otherwise on the front. I have a C64 on a 1081 that runs on green or colour. I wouldn't have thought the green would matter.

The 1084S-P-VDE is a pig cus of the connector and I generally only use that with the Checkmate. Though use the 1081 also on that computer.

Problem with all these monitors is the eventual high pitched whistle which basically means Coopers Ducks and an eventual black screen. Can happen at any time. Lost one recently on the Checkmate.

Inside the Checkmate ...

I saw a 1084S (Philips) with scart connector late 90s in a computer shop.
