I am Not a Geek dot com have posted a review of the 570v entry level flat screen monitor from Samsung. Heres a quick bit:
The 570v is strictly an analog monitor, most 15" TFT's only come in analog. A digital input on a flat screen is far from a must when shopping for one. I recently reviewed a monitor with both analog and digital inputs I could not tell them apart. Digital input is supposed to have less distortion but I assure you that you won't be able to tell the difference. Also if you are going to use a digital flat panel you need a video card with a DVI output which is not very common yet. The only real advantage I found with digital input is you do not have to adjust any of the screen settings.
