flatscreen for dos games resolution blurred, is there a fix? need your opinions

[Unregistered DOS Fan]

These tft screens are very nice to work with but i you change the resolution fitting to dos games the screen appears a bit blurred, you know it all, its no game breaking, but it feels not right, much of the crystal clear dos feeling is lost that way.

So is there a way to fix this like a special emulator or ftfs that supporting lower resolutions, i know that the zsnes emulator can get rid of these problem if you set the emulator resolution higher, but dosxbox is not supporting this option.


Thanks

Things you could try:
1- don't use 'fullscreen' on TFT
2- set windowsresolution in dosbox config to something that suits you (1024x768 or whatever, try things out.... for dosgames better keep it to 4:3 , less distortion)
3- alter output to ddraw or opengl, whatever suits you
4- you eventually can set fullresolution to 0x0 , but that doesn't always work nicely, depends of the TFT settings, .... trial and error.

Read the dosbox manual, it's all pretty swell explained there.

These screens can never support other resolutions than the native one, because each pixel is a physical thing, unlike tube screens, whose pixels are just the places where the electrons are driven to land on a continuous surface. On a TFT any other resolution is converted into the native one for display.

You can play with the DOSBox settings, specially if you want to shrink the image (either full screen or windowed as Dosraider says) so that the scaling factor is an integer. But even in that case it's mostly up to the graphic card settings what scaling gets used.

Not directly related to this particular question, but this is my advice for resolution scaling with DOSBox:
