You have not provided adequate information to simply answer your
question.
Not knowing what you don't know, but knowing enough when asking a
question with the intention of drawing out salient information from
respondents should not automatically generate a superior attitude snotty
comment such as yours !

If I connect my computer to a large television
First lack of information.
Older "HD" TVs were 720p resolution, which, illogically, means
1280x720 pixels
Most still operative HD, FHD, Full HD, etc. TVs and many still for
sale are 1080p, 1920x1080.
The newest 'hottest' (at least marketers hope so) TVs, called '4K',
are actually 3840x2160, which is technically not quite 4K.
Possible mis-assumption. Size of the screen has nothing to do with
resolution. A 1920x1080 image will exactly fill the screen of a 1080p
TV, be it 100" or 10" diagonal in size.
using an HDMI cable will the image fill the entire tv screen
[assuming the same aspect ratio]
In default mode, the TV will show the image pixel for pixel the same
as it comes in. On a 1080p TV, your 1000 pixel wide images will fill
roughly half the screen width.
without loss of resolution or clarity
This is a trick question. Yes, without any loss of resolution. But no,
if it's a really large screen, and/or you sit close to it. By
effectively enlarging what you see, the shortcomings of a lower
resolution image that weren't apparent on a smaller computer screen
will become less felicitous.
, or will the tv screen image appear the same size as it would have
done on my computer monitor [ie: 10" x 6.66"] ,
Asked and answered above. On our 53" wide, 1080p screen, a 100 pixel
wide image will display at ~27" width.
or will the 10" x 6.66" image be pulled out in both direction with a
consequent great loss of resolution and clarity?
Most TV now have various alternate display formats available. Some
would indeed stretch, although likely no equally in both directions,
as they are designed to adapt various standard in put formats.
However, even in default mode, you may well find that it seems that
you have lost resolution and clarity, as above. This is the same
problem that DoF tables have had to deal with for many decades. Also
the reason those giant billboards with iPhone 7 images on them look
great; the billboard is visually no larger than the phone itself,
looked at aver so much closer.
Final mis-assumption: ppi has to do with printing. It is absolutely,
completely meaningless in this context of visual display. Save it at
1000 ppi, save it at 10 ppi, it will display the same on your computer
screen and on TVs. It's only the absolute pixel dimensions that matter.
