FAQ

Consult a Technician First

Before diving into an upgrade, always consult with a qualified technician. They can help you determine if the upgrade is feasible and compatible with your laptop model.

LCD Whitelist

Some laptops have a whitelist embedded in their firmware, which restricts the use of certain LCD panels.
If the new screen’s EDID doesn’t match a model in the whitelist, the screen won’t display an image.
Advanced modifications to the laptop or LCD firmware may be required to bypass this limitation. You need to talk to your technician to determine if this is something your system can handle.

Cooling

Upgrading to a higher resolution increases the load on your video card, especially when moving from 1366 x 768 (1,049,088 pixels) to 1920 x 1080 (2,073,600 pixels)—almost double the pixel count.
Impact on Graphics: If you use your laptop for basic tasks like browsing or social media, the change won’t be drastic. However, if you play 3D games or run graphics-intensive applications, the video card will be under significantly more strain.
Heat Generation: Higher graphical load generates more heat, and if your laptop was not designed for a higher-resolution display, the cooling system may struggle to keep up. Many laptops have limited cooling capabilities due to their compact size, and the system may not be able to handle the extra heat generated by demanding applications at a higher resolution.
Risk Factor: Upgrading the resolution adds strain to your system and may impact long-term performance. It’s done at your own risk, and we cannot guarantee success. If the upgrade doesn’t work, we are not liable. Please use your best judgment.

You Experiment, You Take a Risk

Upgrading your machine with non-manufacturer-approved products is always a calculated risk. Be prepared for the possibility of issues, including screen incompatibility or other malfunctions.

Video Cable Compatibility

The video cable connection and pins must match up properly for the upgrade to work.
Cable Availability: It may be easy to find the right cable for your laptop, or it could be nearly impossible depending on your model.
If the cable is incompatible, the display won’t work correctly or may fail entirely. In some cases, finding the right cable may be challenging or costly, especially for laptops with unique connection types. Always double-check cable compatibility before proceeding with the upgrade.

Do Your Research

Before making any changes, take some time to research your specific laptop model.
Check online forums, especially hardware communities, to see if anyone else has upgraded the resolution on your exact model.
Find out if your laptop’s cable needs to be replaced, what part numbers are needed, and where to source them.
Investigate whether your laptop has an LCD whitelist and if your graphics chip can handle the added load.

Limited Coverage for Small Businesses

As a small business, our insurance coverage is limited when it comes to third-party or non-standard upgrades. Please ensure you understand the risks and consult your technician for guidance before proceeding.

Final Thoughts

Upgrading your resolution can be tempting, but it's not without risks. In many cases, upgrading a popular laptop with a low-resolution display can make it "perfect." However, always be prepared for potential challenges, and consult experts before moving forward. We don’t provide guarantees, and upgrading your laptop screen is always at your own risk.

Fit and Gaps

Removing the touch glass, especially if it's thick, can leave a noticeable gap in your machine's assembly. While some casings may close flush, others won't, resulting in a loose fit that could cause durability issues.

Durability Concerns

Without the touch glass layer, the screen may not sit securely. If you frequently travel or use your machine in active environments, the loose screen could easily break.

Loss of Touch Functionality

Downgrading to a non-touch screen means losing the ability to use touch functions, which could limit your productivity if you rely on it for certain tasks.

Software Compatibility

Machines designed with touch screens often operate as hybrids (laptop and tablet). Switching to a non-touch screen may result in software errors or reduced functionality since your device was built with touch capabilities in mind.

Think Long-Term

While switching to a non-touch screen may seem like a cost-saving option, it could lead to long-term usability and durability challenges. Consider how you use your machine daily before making the change.

Touch-Downgrade

The laptop may not respond properly when switching from touch to non-touch, the new screen may not be recognized. You may receive errors from your device manager.

What is an OEM screen replacement?

OEM (Original Equipment Manufacturer) screens are produced by the same manufacturers that supply screens to laptop brands. These screens match the original quality and specifications.

Are these screens the same as the original?

Yes, OEM screens are identical to the original screens installed in your laptop. They meet the same quality, resolution, and performance standards.

Will an OEM screen work with my laptop?

Yes, as long as the specifications (size, resolution, connector type, etc.) match your original screen. If you're unsure, we can help verify compatibility.

Is an OEM screen different from aftermarket screens?

Yes. OEM screens come from the same factories that produce for laptop brands, ensuring high quality. Aftermarket screens are third-party products that may not meet the same standards.

Why choose an OEM screen instead of buying from an official store?

Laptop manufacturers often charge significantly more for replacement screens to encourage customers to buy a new device. OEM screens offer the same performance at a fraction of the cost.

How do I know if an OEM screen is right for me?

If you want a high-quality replacement screen without paying a premium price, an OEM screen is the best option.

What is a dead pixel?

A dead pixel is a small defect on the screen where a pixel does not function properly. It may appear as a black, white, or colored dot that does not change. These pixel issues can also be referred to as:

• Dead Pixel – A pixel that does not light up and remains black.
• Hot Pixel – A pixel that stays permanently bright (white or a specific color).
• Stuck Pixel – A pixel that remains frozen on one color and does not change.
• Bad Pixel – A general term for any malfunctioning pixel.
• Black Pixel – A pixel that does not illuminate at all.
• White Pixel – A pixel that stays white and does not adjust to display content.
• Not Working Pixel – Another term used to describe a defective pixel.

What is Bliss Computers’ dead pixel policy?

For standard purchases, our policy allows 3 to 5 dead pixels per screen, which is within industry standards. Displays with up to 5 dead pixels are not considered defective and are not eligible for replacement.

Do you test for dead pixels before shipping?

All our screens undergo factory testing to ensure quality. However, individual pre-shipment testing is not cost-effective due to the high cost of specialized equipment and labor.

Do you offer zero dead pixel screens?

Yes, we provide custom pre-tested zero dead pixel screens for bulk orders (such as for military or medical equipment) where precise display quality is critical. This service is not available for single purchases.

Why isn’t zero dead pixel testing available for single purchases?

Testing every screen for zero dead pixels requires specialized equipment and additional labor costs, making it impractical for single-item orders. Instead, we follow the industry-standard dead pixel policy for all regular purchases.
