1440p at 27 inch is perfect

But hard to get new ones for his price.

Nowadays, there are a few options for 24 inch 1440p and 27 inch 4K.

TV is not suitable for gaming because
1. Colour - TV colour is normally worse than monitors
2. Response time - Normally TV has much higher response time, so for playing games you will feel the "lag"
3. Lower lifetime - from my own experience TV usually break down much quicker than monitors, in fact I never have any monitors that become faulty before while the living room had already gone through 2 or 3 TVs

The older thicker LCD TVs.
This is based on personal experience.
Depends on luck, I suppose.
Any HDD I own never last more than 2 years.

But do you ever see a monitor break down?
