If you take retro gaming seriously, you’ll eventually face the question: classic 4:3 LCD, or a modern OSSC Pro + OLED combo?

Eizo S2133 – The Alleged King of 4:3 LCDs
The Japanese-made Eizo S2133 (or the current S2134) is often considered the holy grail of 4:3 LCD monitors. IPS panel, LED backlight, 1500:1 real contrast ratio, and of course a VGA input — everything you need to give your retro PC a worthy display.

First impressions:
+ off-white casing with a pleasant retro vibe
+ adjustable filter (1–5 scale) — at 5, pixel sharpness is excellent
+ fast mode switching, automatic color calibration, analog scan support
+ correctly detects 640×400@70Hz and 720×400 modes (something even many CRTs struggled with)

Then the downsides:
– the text and VGA modes misalign because the monitor treats them as the same
– demoscene-style exotic resolutions (320×200, 50Hz, etc.) often fail or shift
– BIOS screen looks blurrier due to scaling differences
– 60Hz fixed panel — no native 70Hz, so scrolling never feels perfectly smooth

Overall, it’s a beautiful piece — made in Japan — and delivers a clean analog image, but not without quirks.

OSSC Pro + OLED
Anyone who’s tried it knows: the OSSC Pro + OLED combo plays in a completely different league.

+ OLED image is more vibrant, contrasty, and “painted on glass” beautiful
+ razor-sharp scaling, as OSSC Pro offers separate filters per resolution
+ lightning-fast resolution switching
+ handles every weird mode you can throw at it (15kHz, 120Hz, 288p — you name it)
+ on a 34" ultrawide, the image is centered, and the black bars perfectly hide the aspect ratio difference

The result: pixel-perfect, saturated, stable image quality that leaves LCDs in the dust.

Verdict
The Eizo S2133 (or the older but still respectable Dell 2007FP) provides a solid, authentic retro feel — especially if you want to feed VGA straight from your vintage machine. But the OSSC Pro + OLED simply eliminates all compromises: it supports every mode, every resolution, and makes everything look better. So yes, the S2133 might be “the best 4:3 LCD for retro gaming.” But in reality, even the best 4:3 LCD is just a backup plan once you’ve seen the OSSC Pro + OLED in action.
