The Oppo A6 4G has a 6.75-inch IPS LCD at 720 x 1570 pixels, 120Hz and 1125 nits peak brightness. It is the only LCD in a group where the Tecno Spark 40 Pro Plus, Infinix GT 20 Pro and Infinix Zero 40 5G all use AMOLED panels at 144Hz.
The Tecno Spark 40 Pro Plus has the sharpest screen, a 6.78-inch AMOLED at 1224 x 2720 (about 440 ppi), against about 256 ppi for the Oppo A6 4G. It also reaches 4500 nits peak and 1600 nits HBM brightness. The Infinix GT 20 Pro and Infinix Zero 40 5G share a 6.78-inch 1080 x 2436 panel, about 393 ppi.
On brightness, the Infinix GT 20 Pro lists 1300 nits peak, which is 175 nits above the Oppo A6 4G’s 1125 nits peak. The Infinix Zero 40 5G lists 1300 nits as an HBM figure with no peak value. HBM and peak are different measurements, so it can’t be ranked directly against the Oppo’s number.
The Oppo’s refresh rate is also 120Hz, against 144Hz on all three rivals, a 20% gap in motion smoothness. The AMOLED panels also give the rivals deeper blacks than the Oppo’s LCD, a difference an IPS panel can’t match.
Price makes the gap harder to justify. The Oppo A6 4G in 8+256 GB costs PKR 83,000 new, which is PKR 11,000 more than the new Tecno Spark 40 Pro Plus at PKR 72,000. The used Infinix GT 20 Pro (PKR 70,000) and Infinix Zero 40 5G (PKR 75,000) cost PKR 13,000 and PKR 8,000 less, but used prices aren’t like-for-like with a new one. All prices are from retailers.
