uberamd, not trying to rain on your parade (and if that works for you, great!), but my points were more aimed at suggesting the thread starter thinks through this decision rather than just doing it. I've found that often this idea is driven by one of two things:
- A focus on price- as in, I want a big computer screen but I don't want to pay much for it, OR
- A focus on trying to kill 2 birds with one stone- I want an HDTV and I want a big screen for my computer. Maybe I can get both in one buy?
The tradeoff in this is exactly what I posted. The projector suggestion was more to just hammer the idea home. If his needs aren't dependent on screen resolutions beyond 1920 x 1080, then this kind of thinking may work well for him (too). However, if anything that he regularly does with his computer depends on fine screen detail, the more pixels the better. 1920 x 1080 is a lot of pixels, no doubt. But dedicated larger-sized computer screens pack even more screen real estate into the same (and even smaller) sized hardware screens.
"Just do it" is fine advice if his needs match your own. But if the above two bullets are mostly driving his thinking, he may want to consider what he trades off to get #1 or #2. A computer screen is something he might use for hours a day for many years. Saving a few hundred doesn't equate to that much savings over time if any of the stuff I've offered matters to that guy.
