I'm getting a 20" widescreen with these specs:

5ms Response Time

1680 x 1050 Resolution

2500:1 Contrast Ratio

View Angle: 160x160

Brightness: 300cd/m2

Analog Input Signal

It depends what video card do you have, if your video card is able to play games at 1600x1050 than go for 20-22"dayaccus007

What size monitor and maximum resolution do you recommend for gaming?

I want fairly cheap!

19" widescreen?

hmmm sounds like you might need to buy a new monitorcrippo_gamer

you should just be able to buy the power cable and plug it into the wall?crippo_gamer

Most power supplies are like that, and have always been like that since ATX specifications were drawn up. Monitors usually come with power converters on their own, and do not interact with your computer except for on the video cable.RayvinAzn

Are the converters standard (voltage / amps/ watts)?

I live in the UK, where can I buy one?

My new 650w PSU only has a power in socket = no power out to connect to my monitor.

Are most PSUs like this, nowadays?

What do I do?
