Everyone's looking for an upgrade and here i am, looking for a downgrade.

Well, i am currently using Dell U2311H.

Problem: Motion sickness. FPS game is a nono to me except for Counter Strike.

Thinking of downgrading the size.

Would like to remain 1920x1080 though.

Prefer a really crystal clear/crisp image.

Really do not like Dell U2311H's anti-glare screen which i think plays a part in causing motion sickness due to its anti-glaring nature.

Also, due to the motion sickness problem, I would prefer a monitor with a faster response time, lesser to no smearing/ghosting.

Budget below RM 500-600.

Thanks in advance!
