I just got a 4:3 ACER monitor for a DVR I picked up. Plugged in the cameras and picture was horrible....thought I had bad cameras or a crappy DVR....I then took the same DVR and plugged in my desktop CRT monitor and picture was great no fuzzyness or pixelation at all.
My whole thing with LCD's is if the output to the LCD is not the native LCD resolution then the picture will be horrible. Works that way on laptops. CRTs can adjust for this so is the reason why the CRT picture was good.
CRTs don't really "adjust" for different resolutions... they just display pixels differently than LCDs (and plasmas and DLPs and LCD-based projectors, for that matter). With LCDs, there are very sharply-defined edges between pixels, and each "hard" pixel can display the full range of color in itself. With CRTs, each "display pixel" is made of three discrete "hard pixels", one each for red, green, and blue. If an image covers more than one pixel, the color components tend to blend together, rather than being separated by hard edges.

The output on my DVR is 640x480 and the native resolution on the Acer I believe is 1280x1024. Would be great if I could change the DVR output to match but since it is a standalone I am stuck with the resolution provided.
Are you sure? I've set up some VERY CHEAP, VERY CRAPPY off-shore standalones, that had selectable VGA resolutions (granted, limited to 640x480, 800x600, and 1024x768).
Another thing I've found with some cheap standalones is their "VGA output" isn't really VGA... their internals are outputting a composite signal at MAYBE 420TVL, but they have an internal card that converts THAT to VGA... and does a very poor job of upscaling it. Their internal software isn't actually creating a VGA/XGA/etc.-resolution image direct to the VGA port.
