how to get fullscreen windows on dos 7.1

[rynio]

Hello
1. how to get full screen window on dos 7.1.

2.And can i play games like blood on dos 7.1 on virtualbox?

3. Also have question, there isnt any problem with desynchronization(vertical sync)?

1. DOS can't have the resolution you use on the Host, so even if you hit Hostkey+F to enter Fullscreen, it won't fill your screen entirely, because VB doesn't change the Host resolution to match the Guest's.

2. I'm sure you can, but if you can't, maybe DOSBox can help you with it.

3. Do you mean the screen? Not that I know of, DOS is fairly old and it's been at least 10 years or so since I last used it. VB paints the window as the Guest asks it, there isn't a real refresh rate.

i tried dosbox, but it doesnt have vertical sync, its only has 'fulldouble' when i get it to true, then vertical sync on, but sound break off.

I wanna play games like blood on dos 7.1 under virtualbox on fullscreen, is it possible? And isnt there any chance to resize operating area on virtualbox ex. in dos 7.1 ?

You're not giving much info, but instead ask the same question. I guess I have to repeat myself too, but I actually hate it.

If you have you Host and you run it on 1280 x 1024 resolution, the VM won't go any bigger than the 640 x 480 or something it already has. Games can be played in full screen just fine, there is no other mode on DOS. If you want to let the game fill the entire screen, you have to lower your Host resolution to that of the Guest.

i can't get lower resolution than 800x600, but old dos games were less than 640x480.

Well, there you have your answer.

[rynio]

Well, there you have your answer.

yes, its my answer, but i ask: is there any solution, what can i do?

[Sasquatch]

Nothing. DOS can't provide higher resolutions and VB can't alter the Host resolution. You're stuck with a border around your VM display.

[rynio]

ok i have question , why there isn't any stretch mode to resize? It isn't modify resolution, but just stretch display to fit it

[Sasquatch]

VB doesn't stretch the display. It tells the Host to display a picture of x pixels wide and y pixels high. That's all. The host then displays that picture and if it's larger than what it can handle, it will show scroll bars.
