يطلق مصطلح دقة الشاشة للتلفاز الرقمي أو لشاشة الحاسب على عدد البكسلات الموجودة في (صفوف وأعمدة) الشاشة. من الممكن أن يكون هذا المقدار غير محدد بدقة بسبب تأثير العوامل المتعددة في شاشات أنبوب الأشعة المهبطية. ولكن يكون من السهل تحديده بدقة في شاشات البلازما أو شاشات الكرستال السائل أو تقنيات مشابهة بحيث يكون هناك نقاط موزعة على شكل صفوف وأعمدة في الشاشة بحيث يكون هناك عنصر فيزيائي مقابل لكل بكسل من الشاشة (مثلاً: 1280×1024).
