I have a feature request for 70Hz test program. Specifically it should modify line timings so that it produces 720 active pixels, like text mode. The reason is that basically every LCD monitor treats the 70Hz graphic modes as 720 pixels even though they're 320/640 pixels which results in ugly uneven pixels and it makes it harder to judge smoothness of motion in the moving bars part of image because the bars change width as they move across the screen.

Alternatively, there should be moving vertical bars instead/in addition, since the vertical direction isn't subject to this sort of a problem, at least not to this extent.

Ahh that's a great point - didn't even think about it since I use the CRT Terminator setup.

I think maybe the best might be to also add a vertical scrolling element, so one can eyeball using either set of movement. I'll have a look at this.

Bought a "for parts" Samsung 204B on ebay for cheap. Seller said it wouldn't turn on. They likely never recapped the power supply which was the first thing I had to do with my 204b to get it to work. It has a manufacture date of January 2007. So, I hoped it would have the newer revision mainboard.

I dropped it into my monitor, and initially it did not work. It would display with a red hue and the OSD would not function. Fortunately there are some old posts on badcaps.net that mention clearing the EEPROM which stores the settings. It involves shorting pin 5 and 6 on the A81SC EEPROM.

I cleared the EEPROM, and it works!

There is likely another EEPROM that stores the hour/change data, but I just reset those within the service menu. While I have this monitor cracked open, I ordered some new SMD caps to replace the likely aging ones on the mainboard. I'll replace those, and then will confirm I'm not getting any frameskip.

Can 100% absolutely confirm the newer version of the Samsung 204b mainboard does not frameskip at 70Hz. It is buttery smooth. Thanks Tiido!!

Wow, does that make the Samsung Syncmaster 204B 2007 model a unicorn that ticks all the boxes for retro gameplay?
[✓] 4:3 1600x1200
[✓] has DVI and VGA input
[✓] supports full 70hz
[?] how is the image quality and panel ghosting?
[?] how much input latency does the display add?

So far I've regarded the ASUS PA248QV as the best retro monitor, for:
[-] not 4:3 1600x1200...
[✓] but at least is 1920x1200 and has 4:3 mode (though it doesn't work in 4:3 for VGA input, only with CRT Terminator)
[✓] has HDMI and VGA input
[✓] supports full 70hz
[✓] fantastic image quality and no ghosting
[✓] only ~1 msecs input latency + about ~1-2 msecs of pixel switching latency

with Philips Brilliance 252B9/00 as a close second (1920x1200, 4:3 mode, though has about 10 msecs of input+pixel switching latency)

I have not tried to measure input latency (I'm not sure how I can even do it with means I have available) but it should be less than 1 frame, it certainly doesn't get in the way of any of the action games I have played on it.

Blurring is of a typical TN panel of the time, nothing great but not outright terrible either. I have seen far worse, even from modern displays.

Yea the built in VGA scaler isn't great, isn't terrible. I use mine with an OSSC at 2x. The output to the 204b is typically 1280x800 which the monitor does a very nice job of scaling to 1600x1200. Very crisp pixels.

Until someone manufactures a new 4:3 panel (maybe they make a comeback?), I'll be using this.

When I talked about blurring I only meant motion blur of the LCD, and not that of the scaler as it processes the image. I don't actually use the monitor for gaming, for that I have a 20" nokia kinescope right next to it, which puts every LCD to shame on anything that concerns motion. Perhaps if I modify the backlight to strobe in specfic part of a frame, it can become better on that regard but there's little reason when perfection is already right next to it 🤣.

Modern 4:3 panel itself would be nice but just having option to control scaling and aspect ratio would already go a long way. Why is it so hard to offer a nearest neighbor scaling with margins around the image...? 🤣

Wow. I finally brought "the big one" over to my P2 computer, since it has VGA input. This thing is HUGE with DOS blasting out of it!
I was actually surprised with the result, too

That Dell looks a lot like my Acer EB321HQ
According to some unconfirmed sources, they both might be using a BOE BOEA320WU1 panel.

EDIT: even the main logic boards look similar
Acer --> Logic Board 55.T5MM6.004
Dell --> MAINBOARD 201L32BUCFTNDK000 / 320212032901000

EDIT2: the Acer does not have a forced 4:3 mode, only an "aspect" one, which means 320x200 is stretched horizontally. Does the Dell have more flexibility on that front ?

It indeed does. It was initially stretched, but had an "aspect ratio" setting of "auto" or "4:3", which made it look very crisp.
