The size of the icons will look bigger or smaller depending on one thing and one thing ONLY: Pixel Density. Some people on this site refer to this number as "PPI", or pixels per inch. This can easily be calculated using the resolution and size of a display. People often use the website www.sven.de/dpi/ to do the calculations for them.That's the problem. I though that they would look bigger on a bigger screen.
There's not point for me in getting a big TV if the icons/text are gonna look same size like on an 34" monitor. I'd still need to squint and strain my eyes.
I completely don't get how all that resolution/size/dpi shit works.
Using this site, we can see that your 34" Asus has a pixel density of 109.68 PPI.
We can also see that the 49" Sony TV has a pixel density of 89.91 PPI.
This means that icons on the TV will indeed look larger than those of you monitor, though not by much. They'll look about as large as ions on a 24" 1080p monitor.
Hope this helps!
