yes

Depends on the LCD. I've seen some that can do 320 so I would say yes. If not, change the full screen resoltuion of dosbox to 640.

That, and some LCDs do a terrible job at stretching low res images to fill the screen. You may be better off setting the fullscreen res of dosbox to 640 or 1024 and let DOSbox do the streching.

To LCD users:
Describe how the games in fullscreen DOSbox look, does it look blurry or is it acceptable for you. Thanks for reply.

DOSBox is configureable so you can force it to look the way you want

Games wise all [most] old games look crap when compared to recent titles. The only area where bad scaling can be a 'showstopper' is black text on a white background. Try different scaling options (monitor, graphics card driver, DOSBox) and you'll find something that works.

Edit: Windows desktop is the best test for bad scaling. For example, with monitor scaling conifgured if I set my desktop res to 1024*768 I get 'blotchy' text. If I set Fixed Aspect Ratio Scaling, I get blurry text and borders top and bottom. The blurryness is not really significant in an old game given that the result is sorta smoothed similar to a TV output (i.e. not well defined like a TFT).
