Wahoo! :) This project has been a real labor of love for me, I've lost count of the hours I've put in over the last few months testing, and trying to fix issues to make the mini SLG as compatible as possible with all the different hardware out there. All told I think I've made a couple hundred bucks, so I'm definitely not in it for the money!

I got my mini SLG on Friday but did not get a chance to test it out until this weekend.  I hooked it up and was very impressed with how well it works.  The scan lines look really amazing and make the games look very authentic on my 19" Dell monitor, it is a 1905FP.  The only downside is that I am experiencing a big increase in brightness.  I test it in both 640x480 and 1024x768 and it is occuring in both.  The 640x480 looks much better on my monitor so that is what I am running MAME in.  I am using the monitor for a cocktail cabinet so it is being used vertically but the Dell 1905FP has viewing angles of 170 degrees.  I do not have any issues when I unplug the mini SLG and just run the video without the scanlines.  The image is very good and the black backgrounds are solid black.

When I use the mini SLG it takes the black backgrounds and kind of makes them more grayish.  I turned down the brightness on the monitor but it did not seem to make much of a difference.  I also tried adjusting the brightness through the video card settings in windows and also through MAME itself.  Thorugh the video card setting and through MAME I can get the backgrounds to be darker and more black, but in doing so, it dims the rest of the display as well.

The video card I am using is a nVidia 9400GT.  As a test I took out the video card and used the on board Intel chipset.  This appeared to be a little darker than the nVidia was but the black backgrounds were still very grayish.  I think 1500points was reporting a similar issue.  I am trying to figure out the best way to optimize the black backgrounds.  I do not need them to be 100% pure black but I would like them to be darker but not effect the other colors.  I am wondering if it is the video card, the driver, the monitor or some combination of them.

Is anyone else out there using the mini SLG with an nVidia card?  I really liked the picture that CraftyMech posted showing the Donkey Kong scan line comparission screens.  The black looked really good.  I will be trying a different monitor later this week when I can borrow a friends for testing.  I have a piece of tinted plexi that came with the cocktail cabinet that I am converting to MAME.  I have tested with this layed over the monitor and it helps a little bit with the black levels, but once again darkens the whole screen so I don't think that it is the best option either.  I will continue to see if I can figure anything out.  If you have used the mini SLG with nVidia and have had better luck with the black levels let me know what card and driver you are using.  I would also be curious to know about ATI cards and how they are with the brightness. 

I am very pleased with the mini SLG and how well it works, I just need to see if I can tweak it to get the best black levels and still maintain the vibrant colors.

The photo comparison I posted of Donkey Kong was taken running Mame on a Nvidia Ion chipset (Acer Aero loaned courtesy of ChopperDog) and a Samsung SyncMaster 740N LCD. I've been watching eBay to try and snag a Dell LCD or other similar brand as well for testing.

Let me know how the other LCD monitor works out, that will be a big help to know if the brightness increase is more effected by changing video cards (as you tried with the on-board video), or by changing monitors. In the meantime, if I come up with something for you to try out with your driver settings, I'll let you know.
