Current OLED TV LG’s C-Series has always been highly appreciated for its balance between performance and price, the latest LG C5 model is no exception. But the question is, compared to its predecessor, how superior will it be, and should we upgrade or not? To clarify this issue, let’s analyze in depth the differences between the two TV models LG 65C5PSA and LG. 65C4PSA. We are confident that after reading this article, you will make the most accurate choice for yourself.
1. Main improvements of LG C5 compared to LG C4
LG TV The 65C5PSA, although similar in design to the LG 654PSA, contains significant upgrades, mainly focusing on optimizing the viewing experience instead of a revolution in appearance or technology.

The most important upgrade on the LG 65C5PSA lies in the Alpha 9 Gen 8 processor. This chip brings improvements in image processing performance, more accurate dynamic tone mapping and advanced algorithms to adjust images and sound automatically through artificial intelligence (AI).
1.2. Higher maximum brightness

Television The LG 65C5PSA outperforms its predecessor in terms of maximum brightness, especially when displaying HDR content. Measurements show that the 65C5PSA reaches a peak brightness of 1,174 nits, while the 65C4PSA only reaches about 998 nits. Although the increase is not too significant, it is enough to help the 65C5PSA perform better in environments with lots of light, retaining image details and vivid colors even when strong light shines on it.
1.3. Enhanced HDR processing: Reproduce details in the dark

Not only has the brightness increased, but the way the LG 65C5PSA TV handles HDR content has also improved significantly. Although both LG 65 inch TV These all use WOLED (White OLED) panels with Brightness Booster technology, but on the 65C5PSA, you will easily see that the overall contrast is much better, details in dark areas are shown more and colors are more natural. This is a significant plus for those who like to watch high quality movies on Netflix and Prime Video.
1.4. webOS 25 operating system: A smarter experience

LG 65C5PSA OLED TV has been upgraded to the latest webOS 25 operating system. This version offers a smoother, more user-friendly experience, and integrates more intelligent features, including AI-based voice recognition.
2. Compare details of LG 65C5PSA and LG 65C4PSA TVs
2.1. Design: Old bottle, new wine
When placed side by side, these two LG OLED TV models are almost difficult to distinguish. LG doesn’t seem to have changed a bit in terms of appearance, keeping the minimalist, modern design that has created its brand. Both models have a slim, elegant design with a central stand, helping to save space and suit a variety of entertainment spaces.

The thickness of both is less than 5cm at the thickest point, ensuring elegance and sophistication for any space, whether wall-mounted or placed on a table. This inheritance shows that LG does not seem to be too important about changing the appearance, but improving the user experience from the inside is given priority.
2.2. Image quality: Not a big difference, but worth noting
Both of these 65-inch LG TVs use popular WOLED panels with Brightness Bosster technology, not MLA (Micro Lens Array) or Primary RGB Tandem like the flagship models. In theory, the difference between the two TVs is not too big, but if we look closely, we will notice clear improvements on the 65C5PSA that make the visual experience more refined.
Brightness: LG 65C5PSA has higher peak brightness when displaying HDR content. The enhancement level of nearly 200 nits helps LG C5 TV dominate in well-lit environments such as living rooms with many windows or natural light.
Processing performance: Both can handle dark scenes quite well, but the 65C5PSA has the edge thanks to improved tone mapping and enhanced processing performance thanks to the more powerful chip. That’s why LG C5 TV can display the same content more delicately and clearly. Even with low-resolution content, the 65C5PSA handles with slightly better detail than the 65C4PSA, even if only slightly.

To summarize in terms of display, if compared, the LG 65C5PSA is clearly better than the LG 65C4PSA, and is the choice with the most comprehensive image quality in the mid-range OLED segment. However, if you currently own an LG 65C4PSA, upgrading to the new generation is not necessary, because the LG C4 TV itself has performed very well.
2.3. Gaming performance: Premium standards are maintained
Besides movie experience, the LG C-Series is also highly rated for gaming performance, and both the LG C4 and C5 inherit and promote that advantage.
Scan frequency: Like the 65C4PSA, the 65C5PSA supports 4K@144Hz, meeting the needs of most gamers.
HDMI 2.1: All four HDMI ports of the 65C5PSA are 2.1 standard, ensuring compatibility with high-end gaming devices.
Game features: Both are fully equipped with modern gaming features such as VRR (Variable Refresh Rate), AMD FreeSync Premium, Nvidia G-Sync, ALLM (Auto Low Latency Mode) and Dolby Vision Gaming.
Game Optimizer: Provides rich customization for users to have the best gaming experience.

Although LG did not push the refresh rate on the LG C5 to a higher 165Hz like some other 2025 OLED TVs, to be honest, for most console and PC gamers, too high a refresh rate does not bring any particular benefit. Because, current console devices only support a maximum of 4K@120Hz, and if a gaming PC wants to output 4K@165Hz images, its configuration also needs to be extremely powerful to do so. So, 4K@144Hz of both TVs is completely enough.
3. Sound quality: Needs improvement
The sound quality of the LG 65C5PSA and 65C4PSA is comparable, as they both use the same core audio hardware, support 11.1.2 virtual surround sound, and are equipped with AI Sound Pro to improve quality, especially voice.
However, the overall sound quality of both OLED TV models is still not really impressive. The sound is sufficient for everyday needs, but does not really match their excellent image quality, especially when watching blockbuster movies or content with many complex sound effects.
In general, for the best sound experience, users should combine a soundbar or external speaker system for both TVs.
4. Should I buy LG 65C5PSA or LG 65C4PSA TV?
Objectively speaking, smart TV The LG 65-inch OLED evo 4K OLED65C5PSA is a worthy upgrade: a more powerful processor, higher brightness, and smart AI features make for a better movie-watching, gaming, and overall experience.
However, if you already own it smart TV LG OLED 4K 65 inch 65C4PSA then upgrading to the LG C5 may not be really necessary, unless you want the best image quality.
The final choice depends on your needs and budget. If you want the most advanced technology, the LG 65C5PSA is the ideal choice. If you want a great OLED at a reasonable price, the LG 65C4PSA is still a great choice, especially now that it’s on sale.
