<h1>The 15kHz Problem: Finding a Monitor That Speaks Atari</h1>
|
|
<div class="detail-content">
|
|
|
|
<p>Atari ST colour modes (Low-Res and Medium-Res) run at a horizontal scan frequency of 15kHz, a frequency almost no modern VGA monitor supports, since anything made in the last two decades expects at least 30kHz. High-Res monochrome runs at roughly 35kHz and gets along fine with most displays, but colour gaming is a different story entirely.</p>

<h2>Panel Technology Matters More Than You'd Think</h2>
|
|
<ul>
|
|
<li><strong>MVA/PVA panels</strong>, the surprise winners. Their flexible crystal alignment tolerates unusual 15kHz signals far better than standard panels. A NEC MultiSync LCD1970NXp with an MVA panel handles Medium-Res colour reliably, once you fine-tune the H.Size setting.</li>
|
|
<li><strong>IPS panels</strong>, a mixed bag. Some work (a widescreen Lenovo ThinkVision LT1952p reportedly fills the screen beautifully via an ST2VGA adapter), others don't, and there's no way to tell without testing.</li>
|
|
<li><strong>VA panels</strong>, a dead end. Modern VA displays like the Dell SE2722HX and SE2422HX have a minimum horizontal frequency of 30kHz, ruling out native 15kHz signals entirely.</li>
|
|
<li><strong>The universal fix</strong>, an Open Source Scan Converter (OSSC) upsamples the 15kHz signal for any HDMI monitor, at the cost of extra hardware and money.</li>
|
|
</ul>
|
|
|
|
<p class="redacted-note">If you're chasing 15kHz authenticity, buy the specific panel model people have already confirmed working in the forums, don't trust a spec sheet that just says "supports VGA."</p>
