I have a pretty old laptop with Intel HD graphics and it isnt that fast, but it does the job, but i need help with my resolution are there any other ways i could do it or there isnt any.
Ok, we do not know:
Your processor model number.
Your laptop model number.
Your version of Windows 10. Is it 1909?
What the model number of your TV is.
What resolution you are trying to use.
Etc, etc, etc.
Provide some information for assistance.
Go to the NVIDIA Display Properties by right-clicking on the Windows desktop on selecting NVIDIA Display. Under the Display category, select Change Resolution. Select the icon which represents the display you wish to affect and then click Customize. On the next window, click Create Custom Resolution.
