You get what you pay for. Slow delivery. The leds are ok, nothing more, nothing less. Quite dim, and cold white making the image have a blueish tint. In the pictures there are two identical monitors, the left one with OEM CCFL tubes and the right one with these LEDS. The left CCFL one is at 10% brightness, the right LED one is at 85% brightness. Very very dim compared to the original setup. Be very careful when cutting the cable if you have to solder the wires. They made both ends fit the connector, thus swapping colors. If you're not paying attention you could end up with black for POWER and red for GROUND and burn your driver immediatly. Samsung monitors have two Dim channels. ADim and BDim. ADim should work for everyone. But read about BDim and/or if the driver might need some modifications and and try it. Mine on BDim is a bit brighter than ADim. Brightness is mostly 0-10 %; 10-80 % and 80-100 %. There is no linear growth, so find the lowest sweet spot and get used to it. The lower the brighness, les voltage or amperage will travel through leds making them warm less and live longer. EDIT: After about a week in use, the lights started flickering, making it seem like the refresh rate of my monitor was to blame. When I checked - the two resistors in parallel got fried and were showing very high resistance - ~15 ohm for a 1R0 and R620 in parallel which should be about half an ohm normally. I replaced them with a single 1R0 resistor and now the brighness is very bright even at 0%. 0% brigthness on the LED monitors is about 50% brightness on the CCFL monitor. The blueish tint still sucks as much as before, though. Do what you want with this information, but if you are planning to install these you should have at least basic electronic knowledge because they lack in the quality department.
