Hisense Roku TV Slow To Respond? (Here’s How to Fix It)

We understand how annoying it is when your Hisense Roku TV slow to respond to the remote inputs and loading times are unbearable.

Don’t worry–you’re not alone, and we’re about to fix it.

Starting with the answer to the most important question…

Why is My Hisense Roku TV So Slow?

There are many potential reasons why Hisense Roku TV is slow and laggy:

1. Overfilled cache data and file corruption
2. Too much TV background services usage
3. High TV resolution, mostly 4K on 60 FPS
4. Running an outdated TV firmware version 
5. Too many unused channels (full storage)
6. Hardware overheating & thermal throttling
7. Hisense Roku TV system-related problem 
8. Networking issues (only for online lagging)

Let’s continue and chronologically address each of these possibilities!

Hisense Roku TV Slow to Respond – 7 Ways to Boost Speed!

Note: Have you tried restarting the Hisense Roku TV or unplugging it for 60 seconds to perform a power cycle?

1. Clear your Roku System Cache

If your Hisense Roku TV is laggy and everything takes too long to load, the first step is to get rid of all temporary files (cache) that are slowing down the system. 

The cache data is automatically generated, containing app settings, login credentials, and other scripts intended to increase the loading times.

Well, in reality, they can slow down your Roku TV.

To clear the cache on your Roku TV, press the Home button and follow these steps:

• Press the “Home” button (x5)
• Press the “Up” once (x1)
• Press “Rewind” twice (x2)
• Press “Fast Forward” (x2)

This will clear the cache data on your Hisense Roku TV, which may reset some in-app settings and sign you out from your accounts. 

However, test whether your TV performance is now improved.

2. Reduce the Background Usage

The Hisense Roku TV has a lot of background processes working simultaneously as you are using your television.

These settings can slow down your Roku system’s performance, so we will show you which settings are big drainers and how to stop them to speed up the operation.

2.1 TV’s Input Info Gathering

The input data collection allows your Roku TV to dynamically gather data from what you’re viewing and personalize ads for you.

So feel free to disable it.

• Press the Home button and go to Settings → Privacy → Smart TV Experience → Use Info from TV Inputs → Toggle OFF.

2.2 Data Collection & Tracking

The “data collection and tracking” monitors not only what you’re viewing but how you interact with the TV, even networking, with the purpose of ad personalization.

• Press the Home button and go to Settings → Privacy → Advertising → Limit ad tracking → Advertising → uncheck Personalized ads.

2.3 Roku TV Screensaver Time

When enabled, the Roku TV screensaver is constantly tracking the time your TV remains idle, which is another process running in the background.

• To disable the screensaver, press the Home button and go to Settings → Theme → Screensaver start time → Disable screensaver. 

Note: Disabling only one option wouldn’t make all the difference in the world because the magic happens when you disable multiple drainer settings.

3. Lower your Roku TV Resolution

The Hisense Roku TV may be lagging and responding slowly due to the used display resolution, especially if you’re rocking 4K at 60 FPS.

Luckily, Roku TVs allow users to change their display resolution, which is a guaranteed way to relieve the CPU usage and boost the TV performance.

Here’s how to change the resolution on your Hisense Roku TV:

1. Press the “Home” button on your remote.
2. Then, head to Settings → Display Type.
3. Select a lower resolution for the Roku TV.

The recommendation here is to use a resolution that doesn’t run on 60 FPS.

If you use Hisense Roku TV 4K, we recommend trying the “4K HDR 30fps TV” option.

If this doesn’t help with your TV performance, you can go down to “1080p TV” or even “720p TV”.

Note: Lowering the resolution will drastically reduce the quality of the picture!

4. Update your Roku OS Firmware

Sometimes, the slow responses or “input delay” on Hisense Roku TV may occur due to failed or pending system updates.

A quick way to exclude this possibility would be to manually update your Roku TV system through the settings.

• To update your Hisense Roku TV, go to Settings → System → System update → Check now and wait for the scan to complete.

If your Roku system starts updating, that’s good news.

The performance will likely improve after the update, so remain patient.

If the Roku TV is still responding slowly, continue reading ahead.

5. Remove Unused Roku Channels

Another reason why your Roku TV is responding slowly and lagging could be due to full storage and overwhelming memory.

That’s why it’s important to remove all channels that you don’t often use, which will free up the storage and improve the performance.

To remove channels on Roku TV, go to the home screen and highlight any channel you want to remove.

Then press the Star (*) button on the Roku remote and choose “Remove Channel”.

Repeat this for as many channels as you can to free up as much storage as possible on the TV.

6. Check and Prevent Overheating

Well, one of the potential reasons why Hisense Roku TV is responding slowly may be thermal throttling, in simple terms, overheating. 

So, smart TVs have a built-in protection system that monitors the hardware temperatures, and when the thermal margin (heat limit) is exceeded, the performance is automatically decreased. 

This is called thermal throttling, making your TV run slow and laggy, lowering the temperatures.

To justify this, touch the Hisense Roku TV on the back. If it’s unusually hot, well, it’s overheating!

How to Prevent TV Overheating?

There are various ways to cool down your overheating Hisense Roku TV:

If your Hisense Roku TV performance is fast after the TV has been off for a while but becomes laggy after a certain time, it’s overheating.

Note: If you can’t resolve the overheating, your TV cooling system may not be working; hence, it’s best to get in touch with an expert-vetted technician.

7. Factory Reset Hisense Roku TV

Sometimes, the reason why Hisense Roku TV is slow to respond is that you’ve installed or enabled a service without knowing it.

The best way to address ALL possibilities at once is to perform a factory reset, which will cleanly reinstall the operating system, providing a fresh start

• Press the “Home” button and head to Settings → System → Advanced → Factory Reset → Factory reset everything.

You will be asked to insert a PIN code shown on the screen to initiate the restoration, so when the Roku TV resets, test the performance.

Warning: ALL settings and installed channels on your RokuTV will be permanently erased!

Hisense Roku TV Running Slow in Online Apps? (Networking)

Well, if your Roku TV menu navigation is smooth and fluid, but the TV is loading too much while using an online app, this is a whole different story.

Hence, if your TV is not lagging while you are browsing the menus, but online streaming apps are loading slowly, there is a networking issue.

There are many different ways to resolve networking problems:

• Test & Justify Wi-Fi Speed: Connect your smartphone to the same Wi-Fi as your Roku TV and go to speedtest.net, where anything below 5 Mbps is considered too slow.
• Stop the Bandwidth Saver: This option slows down the networking when it detects inactivity, and to disable it, go to Settings → Network → Bandwidth Saver → OFF.
• Switch from 5 to 2.4 GHz Wi-Fi: The 5 GHz Wi-Fi is faster but not as consistent and reliable as the 2.4 GHz Wi-Fi, so go to “Set up new Wi-Fi connection” to switch.
• Switch to an Ethernet (Wired): If nothing works, switch to a wired internet connection by connecting your router and Hisense Roku TV via an Ethernet cable.
