1920x1200 How to add?

Post by mritter0 »

I have RadeonHD.chip 2.18 (08/12/2016) installed (from Enhancer CD). Devs->Monitors->Radeon HD 7800 series I added to the tooltypes MODE=1920x1200@60
Go into Prefs->ScreenMode->Monitors it shows the 1920x1200 resolution.
But in Available Modes, it does not appear. 1920x1080 is the largest.

Is there something else I need to add/change to make it available?

Try adding +RB:

MODE=1920x1200@60+RB

First of all...can your monitor work with anything higher than 1920x1080 (FULL HD), that would be an UHD monitor for example (4096x

If yes, read on, if no, skip and live with the 1920x1080, it's the largest screenmode you'll get with your monitor



You can add whatever screenmode you like until it meets the boundaries of both the gfx card and monitor you have.
Once one of those boundaries are breached the screenmode won't come up as usable.

I take it you have a gfx card that "could" display it

1920x1080 is what the industry calls "Full HD" nowadays, most of the HD screens/monitors are limited to this.
If you want to expand your screenmode to 1920x1200 your monitor has to be able to display that, if you have a FullHD monitor i doubt that it will work, but check your manual.

Thats the easy one, now you have to check if the VSync/HSync Rates are conform with your monitor settings, don't go beyond that or you might harm your monitor

and finally the refresh rates of the screenmode itself, e.g. MODE=1920x1080@60

First of all, Screenmode prefs has a bug where it always resets your setting to 60Hz (default) when you are in the Monitors tab (Manual settings) even if you typed in lower rates in the Monitor tooltypes (your monitor might understand, e.g. i have my two largest screenmodes set to MODE=2048x1440@59 and MODE=2560x1440@59, using @60 the OS would calculate a too high HSync rate for my monitor to cope with and i'll end up a black screen in Workbench) -> already reported
Thats en evil bug btw, if you don't know where to look and land on a black Workbench screen, scary even as i thought i have trashed either my monitor or my gfx card the fist time it happened

So, *if* you want to change the screenmode setting, do it in the tooltypes, set the refresh rate as low as your monitor can cope +1 (just to be on the safe side, and add 1 to it to test where the HSync rates end (you can check them once the screenmode comes up in Screenmode prefs (just click on it and you'll get the calculated HSync rate)

I use two seperate monitors at different desks one a 1920x1080P and a 1920x1200.

My simple answer is that I have the prefs screenmode/monitor tab (detect setting automatically) checked.

So when I use my 1920x1200 it just "knows" it's there correctly.

+RB did not help.

Checking "Detect settings automatically" and some reboots did the trick.
