37" may be too much monitor for distances typically used with a computer.
It depends on your own needs. It could be good to deal with vision issues.

As for the 1080p part of this, be sure you know for sure what the NATIVE
resolution is. Some 1366x768 HDTVs reach up to the 37" and 42" sizes.
The native 1920x1080 ones cost more. Then make sure you have the computer
configured to exactly match the monitor. If you install with that monitor
in place, it should do this fine. In many cases it will even if you just
switch monitors. But if not, you'll need to force the setting. It is more
likely to just work right if you use a DVI or HDMI output from video card
than if you connect up with the old VGA analog to an analog input (which
will also require pixel lineup which not all monitors do well automatically
and even fewer HDTVs succeed at for computer use).

I have a smaller HDTV in the 19" size that I sometimes use on computers when
I'm building them new and don't want to pull my real monitor from the computer
desk out to the table where I'm building. This HDTV is convenient for this,
but it has one bit of an issue. When I boot up many OSes, the switch from a
text video mode at boot, to a graphical video mode, triggers the automatic
pixel lineup. But the software is only displaying some small activity area
in the middle of the screen and for a while the background is otherwise black.
This fools the TV when it tries to figure out where the active visual area of
the analog signal is, and it gets it wrong because all it saw was some small
stuff in the middle initially. Later more is displayed and it goes off the
edge. I have to make the TV reset the pixel lineup again later to get it done
right (flipping to a TV channel then back to VGA again does it).

PS should get the images right unless you try to make the images exactly fit
the full screen and they aren't really 16:9 images. Just let PS put the image
in a window to work with. This along with correct matching video setup and the
aspect ratio should remain correct. If you then want to use one of your fine
works of art as a computer background image, be sure to crop it to a 16:9 (not
a 16:10 as most widescreen computer monitors use) size, preferrrably an exact
1920x1080. Then also make versions for 16:10, 4:3, and even 5:4 if you want
to share that picture for others to use as screen backgrounds.
