Does the color of the IBM Badge indicate the screen spec?

#1 Post by Thinkpad4by3 » Sat Jul 29, 2017 7:23 pm

Ok, so I just noticed that monochrome IBM models seem to have an all BLUE badge while the color models have the RGB badge. Is this accurate?

Yes, models such as 340, 365 or 750 with a monochrome display will have a blue "IBM" badge on the lid and cover, while color machines such as 755C, 380ED or others will have the RGB "IBM" badge (please note that DSTN and TFT use the same badge)

Actually about that, for some darned reason my 755C has a TFT display with TWO SLIDERS unlike regular TFT displays that have 1. Its really wierd. And I know its TFT for certain because the colors are sharp and very vibrant with nice refresh rates and no ghosting. Maybe IBM refurbished it but couldnt find the normal TFT inverter so they swapped the inverter?
