Display

The OPPO K14x 5G has a 6.75-inch HD+ IPS LCD display with a resolution of 1,604 x 720 pixels and a 120Hz refresh rate confirmed by OPPO India’s official press release. The peak brightness is 1,125 nits also confirmed by the official press release. The display has a punch-hole cutout in the top-centre for the front camera.e.

The 1,125 nit peak brightness is useful in India’s outdoor conditions. OPPO’s Outdoor Mode 2.0 confirmed by OPPO India automatically pushes brightness to maximum when ambient light is detected, keeping the screen readable in direct sunlight.

OPPO K14x 5G Camera

The 50MP primary sensor uses PDAF  Phase Detection Autofocus confirmed by Xpert Kashi. PDAF locks focus faster than contrast detection autofocus, which means the K14x focuses on subjects more quickly than entry-level phones with older autofocus systems.

Video recording on the rear camera goes up to 1080p at 60fps confirmed by Gizmochina. The front camera records at 1080p at 30fps. There is no 4K recording  which is typical for phones in this price segment.

OPPO has loaded the camera app with several AI features  all confirmed by OPPO India’s official press release. Removes unwanted objects or people from a photo after shooting. You tap on what you want removed and the AI fills in the background naturally.

In daylight, the 50MP sensor captures detailed photos with accurate colours confirmed by 91mobiles. Low-light performance is average for the price  the f/1.8 aperture lets in reasonable light but the small sensor size limits performance in dim conditions. AI processing helps but cannot fully compensate for the hardware limitations.
