I just re-tested the Philips 252B9 at both 1600x1200@70Hz and 1920x1200@75Hz and also my Acer EB321HQ at 1920x1080@70Hz with vsynctester.com . In all cases, the beach scene scrolled very smoothly . Thank you darry. About the OSSC, is it able to handle gracefully the switch between 720x400@70 / …

Verdict : Except for f) , this monitor is practically perfect for 4:3 retro needs when used with an OSSC and VGA source as well as, optionally, an FX 5900 with an EDID emulator for 70Hz . Many thanks for your testing and quick report, darry! :) I have noticed while testing a cheap Acer fullHD …

Thanks for the detailed explanation darry, it makes a lot of sense. I probably thought 720x400 was used in mode 13h because that's what some LCD OSD would show, but I realize now it's a lot more logical for the video card to simply double the horizontal lines. I suppose a LCD scaler would need a …

The Philips 252B9 looks really good! Looking forward to your review 😀 BTW I thought the VGA output for 320x200 games was 720x400, not 640x400. Is this correct? In either case line doubling would work the same I suppose.

Awesome! It's too bad 1600x1200@70 is not supported by your nvidia card iirc. Do you think that perhaps by resucimg blanking it could reduce the pixel clock enough for it to work?

My 75Hz IPS Acer VW257 does not smear or ghost in a noticeably annoying way at 70Hz , at least not to my eyeballs. No dropped frames are apparent using Pixperan through DVI/HDMI at 70Hz . I have recently noticed though that running at 70Hz vs 60Hz gives static flat surfaces a slightly "textured" …

Oh, I thought you were using one of these old, ~2008 era 1600x1200 monitors. I did try a 1920x1200 monitor last year, but I was a bit disappointed by it. As far as I understand, almost all 1920x1200 displays use an IPS panel (a few use PLS, which is a similar tech), and I found it to have pretty bad …

I am curious as to why you prefer 1280x960 to say 1600x1200 . Is it to get the integer scaling of 640x480 ? My reason for preferring 1600x1200, (on a 1920x1200 display due to 1600x1200 no longer being made) is to get close to integer scaling for 320x200 (640x400) with an OSSC (and maybe eventually …

I would really like to see a 1280x960 LCD on the market that could upscale 720x400 without artifacts and able to handle 70 Hz without dropped frames. Pro ably not going to happen though 🙁

About the Voodoo 5, is the excessive price really worth it? It seems one could get a Voodoo 3 (which is what I currently have) for games up to '99 or so, and a GeForce for later games. Both are sellers pics although I have already received and tinkered with the athlon. Very interesting (and to my …

Not a 486 game but the EGA version of LOOM looks incredible imho, a superb demonstration of what can be achieved with a limited color palette.

Thanks Darry and Oetker. By the way, I was mistaken: it is a Voodoo 3 3000 (not a 2000). Anyhow using MTRRLFBE did not fix it unfortunately, but flashing the BIOS to version 2.5.12SD fixed the problem completely, so that's great 😀

Thanks Darry. About the Voodoo 3, I've recently received a Voodoo 3000 2000 and I'm noticing something strange: a couple games (like Worms) and DOS text programs cause what seems like bits flipping in the VGA output (it appears as random pixels turning on and off, rather distracting).
