Handy video - thanks!

Not sure if you know this. But some EGA cards (pretty sure this includes ATI EGA Wonder) allowed 350-line EGA on a 200-line CGA monitor using interlacing. Also, some could even simulate a 64-color EGA palette on a standard 16-color CGA RGBI connector using clever tricks. Maybe read the EGA Wonder manual? Cheers and thanks for the video!

Monkey Island 2 has a sort of dithering filter over the VGA graphics if you start it on an EGA system. Looks fairly grainy on a standard VGA screen, but much less so on this one.

Exactly. It uses 640x200 and each VGA pixel is mapped to two EGA pixels.

I have the variant of that monitor without TTL support.

Maybe it can be modded. Similar to my model that is missing the separate Luma/Chroma input.

Good video, but please consider applying a low pass filter to the audio when recording footage of CRT monitors. I'm in my mid-30s and haven't been able to perceive CRT whine in years, except at the beginning of this video where I find it absolutely ear-piercing. I can only imagine that it'd be agonizing to younger viewers, especially on headphones. Maybe also an indication that there's something wrong with the monitor, because I don't think this intensity is normal.

LOL. Thanks for the feedback! My kids can still hear it - for me it’s very attenuated. Let me check if Final Cut has a narrow band filter that I can tune to the 15-16kHz range.

You should try Ironman offroad and see if it supports the 64 color mode (most, if not all, ega monitors ignore intensity pin when in lo-res mode) with redefined palette...

Good idea! But I bet that the CM8833-II doesn't support the extra intensity pins. Would be an interesting experiment, though! Also: Wouldn't that use the inverted sync signals, too? That was used by IBM EGA monitors to do the autoswitching, I think.

That trick only works on real EGA monitors with 6 color pins (rRgGbB). This monitor only has the usual 4 (RGBI).

Thanks for the confirmation, Jim. I doubted that the Philips would have extra intensity pins. I think that was only supported by EGA and perhaps some Multsync monitors?

I switched to Nec71vm's with different Adapters (like mce).

Yeah, I do have the RGBtoHDMI (with adapter for EGA and CGA!) and it works great. However it is nice to see EGA on an actual CRT for once!

Ja, verständlich, die kosten ja auch Platz. Aber ich bin total dafür, dass Philips nochmal eine Auflage von 13" Farb CRTs rausbringt! :-D

Vermutlich ironisch von dir gemein? :-D Sehr gut sicher nicht, aber weltweit vermutlich ein paar tausend an Nerds. Ist aber nur Wunschdenken. Ich mag CRTs einfach gerne aus nostalgischen Gründen, und aufgrund der Tatsache wie sie funktionieren -- Elektronen per Magnetfeld irrsinnig beschleunigen, so das sogar Röntgenstrahlen entstehen??? Quasi der Teilchenbeschleuniger für zu Hause!
