saving the grid plot created with high resolution 300 dpi

[kcsb]

I have created 4 separate plots using proc sgplot and arranged them in a 2x2 grid. when I am trying to save the grid plot to my device, it saves all the four plots individually and not the grid plot. Here's the code I am using:

ods listing gpath='path';
ods graphics / imagename="test.png" imagefmt=png;
title 'Panel Plot';
ods layout gridded columns=2 rows=2 column_gutter=0cm row_gutter=0cm column_widths=(14.5cm 14.5cm);

ods region;
proc sgplot data=work.mod1;
series x=Pt_no y=pred1 / group=Group markers;
label Pt_no = "x" pred1 = "y";
title "abc";
styleattrs datacontrastcolors=(big bib crimson);
run;

ods region;
proc sgplot data=work.mod2;
series x=Pt_no y=pred2 / group=Group markers;
label Pt_no = "x" pred2 = "y";
title "bvdfb";
styleattrs datacontrastcolors=(big bib crimson);
run;

ods region;
proc sgplot data=work.mod3;
series x=Pt_no y=pred3 / group=Group markers;
label Pt_no = "x" pred3 = "y";
title "vsedf";
styleattrs datacontrastcolors=(big bib crimson);
run;

ods region;
proc sgplot data=work.mod4;
series x=Pt_no y=pred4 / group=Group markers;
label Pt_no = "x" pred4 = "y";
title "vsrdgr;
styleattrs datacontrastcolors=(big bib crimson);
run;

ods layout end;

is there a way to save the grid plot with 300 dpi resolution?

Thank you so much!

The plots are getting saved individually. Is there a way I can save the grid plot I created?
