Our Verdict
LG C3 OLED
Samsung S90C OLED
The LG C3 OLED and the Samsung S90C OLED are similar TVs occupying the same market position. Of the two, the Samsung is the better gaming TV and slightly better overall TV, while the LG is the better TV for movie fans. The Samsung has a wider color gamut and gets brighter than the LG, especially in HDR; not only that, but it also maintains its HDR brightness better in Game Mode. It also supports 4k @ 144Hz (120Hz on the 83-inch model), while the LG is limited to 4k @ 120Hz. However, the LG supports DTS audio formats and Dolby Vision, making it great for Blu-ray fans. It also has better low-quality content smoothing than the Samsung TV, making it better for watching streaming content, especially in low-bitrate situations.

Was XE Wireless tested in competitive mode? Or is it the default?
Also, was motion sync turned on?
Hi, could you please mention which firmware was used? Apparently their competitive firmware gives the best results
Mouse: VAXEE XE Wireless (v5) 23.08.22 Receiver: VAXEE XE Wireless (v5) 23.08.22
Hey thanks for reaching out! We tested both the High Speed Mode (Default) and tested the Competitive mode firmware. Stay Tuned for the full review to read about the results.
The full review has been posted here. Let us know what you think!
4K dongle has been released. Can you test it?
Hey bmkbmk, thank you for reaching out. We will be ordering the 4K dongle, and we will test the Vaxee XE Wireless once we receive the dongle. Stay tuned for an update in the coming weeks.
Is this in progress?
Hey bmkbmk! We just recently received the 4k dongle for the Vaxee. At the moment our testers have their hands full, however this will be retested as soon as they become available. We are aiming to retest it within the next week or 2. We appreciate your patience.
Can you tell me the delay(Start, half, end) of 800 and 1600 dpi in competition mode with motion sync turned off?
Hello bmkbmk, Thank you for your interest in our mouse reviews.
Here are the results for mouse in competitive mode with motion sync off at 800 dpi: Delay to start of movement: 12.2ms Delay at half movement: 2.6ms Delay to end of movement: 2.1ms
The latency at 1600 dpi will be slightly lower than at 800 dpi.
Hi when will the test be updated for 2khz and 4khz?
Hello, We’ve just finished testing the mouse at a 4000Hz polling rate . Stay tuned, the review should be updated with the new performance results soon.
Update: We bought and tested Vaxee’s newly-released VXD02 wireless receiver, which adds support for a new maximum polling rate of 4000Hz. We’ve added new information about this receiver in several sections and added supplementary test results in the Sensor Latency and Click Latency sections. However, we haven’t altered our original scoring.
I would like you to measure 1k and 2khz sensors using a 4k dongle.
Hello Rumad, We’ve conducted tests on this mouse at 1000Hz using the included dongle, which remains the configuration we anticipate most users will utilize. Additionally, we’ve recently published results for the mouse tested at 4000Hz with the VXD02 receiver, revealing negligible differences compared to the 1000Hz results. Currently, we do not intend to conduct further performance testing at lower polling rates, as we anticipate the results would be insignificantly different from those previously obtained.
The firmware of the 4K dongle has been updated and it seems to be working better than before, so I’d like you to check it out.
Now, only sold with 4K dongle include. so 4k should be the main and new 4K enhanced firmware is now available, please test it out
Hello, Thank you for bringing this to our attention. We plan to update our Vaxee XE Wireless receiver to the latest firmware and retest the mouse to ensure our review reflects these improvements.
Additionally, since the mouse now comes standard with the 4000Hz receiver, we will update our review to feature the 4000Hz results as the main results. This will provide a more accurate representation of the mouse’s performance for new buyers.
We appreciate your patience and will post the updated results as soon as the testing is complete. If you have any further questions, feel free to ask!
Haven’t you re-verified yet?
Hello Rumad, We haven’t had the opportunity to retest this mouse yet on the newest firmware yet, but rest assured, it’s still on our to-do list. We understand your anticipation and truly appreciate your patience. Please check back soon for our updated results, as we aim to provide the most accurate and comprehensive reviews possible.
Thank you for your understanding and continued support!
I’m looking forward to it!
Update: We’ve updated the review to reflect that the mouse is now only available with the 4000Hz receiver.
