correlation plot of high dimensional data looks unreadable

I am trying to do a correlation plot using corrplot in R with a high dimensional data consist of more than 100 variables. But the plot is unreadable as the r values in the cells are jumbled as it cannot accommodate the large (121 * 121) matrix in the plot. How can I make a bigger size plot so that the numbers are readable. This the command I used corrplot(c, method="number", tl.cex = 0.6). correlation plot using corrplot in R.

The problem is that you cannot expect the numbers to be visible. There simply is not enough pixels on your screen to display the text.

What I would try is saving the graph in a pdf file:

pdf("file.pdf", height=45, width=45)
corrplot(c, method="number", tl.cex = 0.6)
dev.off()

Then open "file.pdf":

And zoom in to see the numbers:
