The pixels are engineered differently and are bigger on TV's so text looks crap.
The colours on TVs are nearly always over saturated so people see them and think wow much like the Dr.Dre beats headphones that have way too much bass.
Monitors like the ultrasharp line have better build quality than a TV.
Monitors have higher resolution meaning better picture quality and more screen estate.
TVs have big stupid ugly bezels (except the new thin ones)
TVs are nearly always glossy I hate gloss.
Monitors have better input speed.
TVs are usually too bright up close.
TVs are made more in bulk so cheaper production costs with SMT soldering.
Components of monitors are harder to source for PCB assembly
Monitors use 16:10 ratio instead of 16:9 (God I hate 16:9)
Wrong, majority of monitors are 16:9 and all 3D/120hz models are aswell
TVs use SPVA panels instead of IPS. IPS you get more color accuracy, gammut, and viewing angle.
True but for fast paced gaming such as FPS a TN panel with a high refresh rate beats all, IPS is good for MMO's etc.
3D Tvs usually don't actually accept a 120hz input but only have 120hz output so useless for gaming.
All tv's have a 60hz input since that's all they need to use, even when advertised at 600hz it displays the same frame 10 times rapidly but that doesn't give a better picture
