Answer 1

I was looking for the same answer and your question actually put me on the right track.
From inspecting the TCPDF class, ended up finding the answer in the TCPDF_STATIC class, in the static method TCPDF_STATIC::getPageLayoutMode().
The correct function to use would be TCPDF::SetDisplayMode($zoom, $layout, $mode). For your purpose I'd suggest:
$pdf->SetDisplayMode('default','OneColumn');
OR
$pdf->SetDisplayMode('default','continuous'); // continuous not documented, although should work.
Possible values for those parameters are as follows (from the method's PHPdoc):
$zoomThe zoom to use. It can be one of the following string values or a number indicating the zooming factor to use.
fullpage: displays the entire page on screen
fullwidth: uses maximum width of window
real: uses real size (equivalent to 100% zoom)
default: uses viewer default mode
$layoutThe page layout. Possible values are:
SinglePage Display one page at a time
OneColumn Display the pages in one column
TwoColumnLeft Display the pages in two columns, with odd-numbered pages on the left
TwoColumnRight Display the pages in two columns, with odd-numbered pages on the right
TwoPageLeft (PDF 1.5) Display the pages two at a time, with odd-numbered pages on the left
TwoPageRight (PDF 1.5) Display the pages two at a time, with odd-numbered pages on the right
$modeA name object specifying how the document should be displayed when opened:
UseNone Neither document outline nor thumbnail images visible
UseOutlines Document outline visible
UseThumbs Thumbnail images visible
FullScreen Full-screen mode, with no menu bar, window controls, or any other window visible
UseOC (PDF 1.5) Optional content group panel visible
UseAttachments (PDF 1.6) Attachments panel visible
public function SetDisplayMode($zoom, $layout='SinglePage', $mode='UseNone') {
if (($zoom == 'fullpage') OR ($zoom == 'fullwidth') OR ($zoom == 'real') OR ($zoom == 'default') OR (!is_string($zoom))) {
$this->ZoomMode = $zoom;
} else {
$this->Error('Incorrect zoom display mode: '.$zoom);
}
$this->LayoutMode = TCPDF_STATIC::getPageLayoutMode($layout);
$this->PageMode = TCPDF_STATIC::getPageMode($mode);
}
