my viewing distance is aroun 60cm. Do you reckon thats too close for a 24" or enough?
Could you tell which has the best colors/performance regarding the specs? is the 2ms respons better for gamin or there isn't really a big difference?
As I said no HDMI should I get one with HDMI or is dvi enough?
Both will have about the same color since both use the same type of LCD panel; TN.
Generally not much difference between 2ms and 5ms for gaming. Hardcore gamers tend to go for 2ms just because the number is lower.
The only difference between HDMI and DVI is that HDMI carries both video and audio signals. If your monitor has speakers and you want to use those speakers, then you can just use HDMI, or use DVI and an audio cable from your sound card to the monitor.
