Hello,

I hope my query does not voilate the forum rules.

I going to purchase a 23" monitor but cannot decide with one to buy. Dell ST2310 23 has 250 cd/m Brightness with 50000:1 contrast ratio. the other one, Dell SP2309W 23, has 300 cd/m Brightness with 80000:1 contrast ratio. I will mainly use for education purpose, sometimes play pes 2010 and maybe watch a film but that is very rare. My question is how much of the difference is there between 250 cd/m brigthness and 300 cd/m brightness for a 23" widescreen monitor. If there isn't much difference in brightness then then I can go for the ST2310.

Thanks for the advise.

Quick clarification: cd/m^2 (candela per square metre) is a measure of screen luminance. Numerically 300 cd/m^2 is 20% brighter than 250 cd/m^2, but that percentage rarely translates into a dramatic perceived difference in everyday use. For classroom or home use, web work, and casual gaming (like PES 2010) the lower figure will usually be perfectly adequate — ambient light, panel coating, and your brightness setting matter more than the raw spec.

Manufacturer contrast figures (50,000:1, 80,000:1, etc.) are almost always dynamic ratios and not useful for comparing real image quality. The things that make the biggest visible difference are panel type and quality (viewing angles, color uniformity), actual static contrast, backlight uniformity, and how the monitor performs after you set brightness/contrast and, if needed, apply a simple calibration/profile. Unit-to-unit variation can be significant, so measured reviews are far more helpful than headline specs.

Practical tips: try to view both models in the lighting you plan to use, or buy from a retailer with a good return policy. Reduce the OSD brightness from its maximum to a comfortable level (many people find 100-150 cd/m^2 comfortable indoors), and use built-in presets or a basic calibration tool if color accuracy matters. Since pointed to a review earlier, prefer sources that publish measured luminance/contrast rather than marketing numbers. Given s follow-up — choosing the ST2310 and finding no problems — reliability and how the unit looks in your environment are often the best tiebreakers.

Hi prixat,

thanks for reply. I decided to buy ST2310 the day after I started this thread. I orignally had problems with the samsung p2250, twice actually by replacement. The connector in the monitor, the cable power supply. So far no problems with the ST2310.
