Text Objects can be displayed as #COM type errors, or as the text overlaid with a dithered pattern if the "display value" expression has “uncertain” quality.
This setting allows switching between these two modes. This type of indication is active only when IgnoreValueQuality = 2.
0 – Show the result of the "display value" expression overlaid with a dithered pattern.
1 – Show error status as #COM type errors.
Default Value: 1
