I'm still curious about that ati vga wonder+ and if it's any more compatible then the XL

Does anyone know if there's a mode switching utility for Cirrus Logic cards, like there is for Tseng, ATI, Trident and OTI cards? I haven't found anything i suspect that newer ISA Cirrus Logic can't switch to CGA mode which is really unfortunate.

AFAIK, newer CL cards don't have special CGA emulation.
I still take test results and software utilities posted here and will put them up to the top of the tread.

Not even the AcuMos chipsets that were later rebranded by CL?
There's also Realtek cards, which also i know litle about.
It seems that only Tseng, Western Digital, Trident and Oak have DOS utilities to change their graphics mode.
I needed to add some monitor calibration tests to the CGA compatibility tester, so: Surprise! New version (v1.1) is available at http://www.oldskool.org/pc/cgacomp . Features added to the new release:
Much of this work was done because I'm going to start making videos of authentic CGA output, and needed a way to stress any capture/processing solutions I will be experimenting with.
^Thank you for this!

I have found the display mode utility for Realtek cards, and i also know that Chips and Technologies cards also had a switching utility which i could confirm by reading the manual. Unfortunately i haven't found the utility for the C&T cards yet.
Oh boy! Thanks! Time to break out my 286 and test my Trident again 😎
Life? Don't talk to me about life.

If your card can truly do a CGA 8x8 font properly, check out the VileR artwork by selecting the m6845 -> row reprogramming test. After the first pic, his new artwork is the second pic. It's truly amazing.
I think the aspect ratio pattern will surprise some people. Not a lot of people realize that a real IBM CGA 5153 monitor is not 4:3 square pixels; it's "squashed" vertically and is really 8:5.

Thanks (for both the compliment and the advertisement). 😀
For anyone testing this in DOSBox, it'll fail the last test ("Composite: low-res graphics"). This may indeed be the same problem as with Bruce Lee (see DOSBox vs. real hardware) - the fix for BL (included in the Daum build) fixes this one as well. However, this time it thinks it's in text mode, which I just verified with the debugger.
New release of the CGA Compatibility Tester, in which Jim completely removes the aspect ratio test pattern and replaces it with something sensible. Here's what's new in v1.11:
It's usable as a monitor calibration tool too, BTW.
There is some ambiguity surrounding how an IBM 5153 monitor should be adjusted in terms of aspect ratio, so the primary reason for the new version was a new aspect ratio pattern meant for NTSC composite monitors (for which the aspect ratio is fully known).
Another new release; you can grab it from http://www.oldskool.org/pc/cgacomp as usual. I'm gearing up for making captures of CGA from the real hardware, so I added some test plates and options that help if you are trying to do that (both with a capture solution as well as a videocamera.) Full list of new stuff:
My belated thanks for updating the CGA tester, Trixter.
One question: what do the different CGA features weigh in comparison to each other ? I guess some are much more important than others when talking about CGA games.
I have a Trident 8900D in my XT clone (on a HP P1100 CRT) which has trouble with the double and strikeout cursor and start address reprogramming.
What will NOT work or produce garbage, which game/demo should I try ?

Thanks!
...So that's why those dual-chip "Holy (C)Gr(A)il" Paradise cards are so expensive.

Very few VGA cards, even with CGA TSRs loaded, will play Defender of the Crown properly for example.
