Had my 15" tft for 6 month nd finally found there is a loose connection at the back of it causing the screen too shut off. I love the monitor and am well within my rights too have it fixed. But also within my rights too get a refund and maybe see this as an opportunity too upgrade too 17". Budget of £280. Also is it worth the extra cash. More chance of dead pixels. What sore of response time should i be looking for seen as i am well into gaming, 14ms????
