black and white screen

Post by jky445 »

I connect several things from my PC through UltraVNC, but if I connect only one of them, it comes out as a black and white screen.
The version used is 1.2.1.6.
Will it disappear if I update the version?

I wonder how I can solve it.

An upgrade takes the settings from the previous install.

If you selected full color/256color/B&W you still have the same settings after the upgrade.
The color settings are viewer settings and can be changed on the fly

4-Gray image

Post by jky445 »

When connecting ultravnc viewer, all settings are set to Full Color.

Running with the same settings, only 1 out of 16 PCs comes out similar to the 4-gray image.

I had this problem before, but after using it, it suddenly came back to full color at some point.

I have two thoughts.

1. The pc's network problem
2. Bug caused by lower version of ultravnc

What should I do if the settings appear like 4-Gray images even if I set the settings to Full Color and run it?
